If you're like most people, you probably think of olive oil as a healthy cooking oil. But what you may not know is that olive oil has some amazing health benefits, including the ability to improve brain function. In this blog post, we will discuss the science behind olive oil and brain function and explore how this powerful oil can help improve your cognitive performance.
What is olive oil and where does it come from
Olive oil is a type of vegetable oil that is extracted from olives, the fruit of the olive tree. Olives are thought to originate from the Mediterranean region, and they have been cultivated for thousands of years. Olive trees are well-suited to the Mediterranean climate, and they produce a high quality of olive oil. The oil is then extracted from the olives using a cold-pressing process. This process helps to preserve the flavor and nutrients of the oil. Olive oil is a popular cooking ingredient, and it is also used in cosmetics and pharmaceuticals. It is a healthy source of fat, and it contains antioxidants that can protect against cell damage.
There are many benefits to using olive oil, both for cooking and for health. Olive oil is a healthy alternative to other oils, as it is lower in saturated fat and contains high levels of monounsaturated fat. In addition, olive oil contains antioxidants that can protect against cell damage. Some studies have also shown that olive oil can help to lower cholesterol levels and reduce the risk of heart disease. When used for cooking, olive oil can add flavor and depth to dishes. It is also a healthy way to cook, as it does not produce harmful chemicals when heated. Overall, olive oil is a versatile and healthy option that can be used in many different ways.
How olive oil can improve brain function
Recent studies have shown that olive oil can improve brain function. The main active ingredient in olive oil is oleocanthal, which is a powerful anti-inflammatory. Studies have shown that inflammation is a major contributing factor to cognitive decline. By reducing inflammation, oleocanthal can help to improve brain function. In addition, olive oil also contains antioxidants, which can protect the brain from damage. These properties make olive oil an ideal food for people who are looking to improve their brain health.
The science behind olive oil and brain function
Olive oil is a healthy fat that has been shown to have numerous benefits for the body, including brain function. Numerous studies have shown that olive oil can help improve cognitive function and memory, as well as protect against age-related decline. The beneficial effects of olive oil on brain function are thought to be due to its high content of monounsaturated fatty acids, as well as its antioxidant and anti-inflammatory properties. Additionally, olive oil is a rich source of phenolic compounds, which have also been shown to boost cognitive function. To get the most benefit from olive oil for brain health, it is best to use extra virgin olive oil, which contains the highest levels of these beneficial compounds.
How to use olive oil for better brain health
There is growing evidence that olive oil can help to improve brain health. Numerous studies have shown that olive oil can help to protect the brain from age-related damage, and it may also have neuroprotective properties. One way to get the benefits of olive oil is to take a teaspoonful each day. This can help to increase levels of healthy fats in the brain, which are essential for cognitive function. Another option is to use olive oil when cooking. This can help to improve the absorption of nutrients from other foods, and it also provides a healthy source of calories. Also, your body needs fats to manufacture hormones. Either way, incorporating olive oil into your diet is a simple and effective way to boost brain health.
Olive oil a needed fat for the body to produce hormones.
While fat has gotten a bad rap in recent years, the truth is that our bodies need fat in order to function properly. Fats help to insulate our organs, protect our joints, and produce essential hormones. And while there are different types of fats, olive oil is one of the healthiest choices thanks to its high levels of monounsaturated fatty acids. These healthy fats can help to lower bad cholesterol levels and reduce the risk of heart disease. In addition, olive oil is a rich source of antioxidants, which can help to protect cells from damage. So next time you reach for that bottle of cooking oil, remember that olive oil isn’t just good for your health—it’s essential for it.

Olive Oil Can Help Preserve Memory And Prevent Alzheimer's
June 24, 2017 12:14 PM
Alzheimer's disease affects nearly 44 million people worldwide. According to a study done by researchers at Temple University in Pennsylvania, olive oil can help preserve memory and essentially prevent Alzheimer's disease. Dominico Pratico, lead researcher of the study, stated that olive oil helps reduce inflammation and activates a process in the brain called autophagy. Autophagy is a way that the cells in the body break down and clean out unwanted debris in the body. Mice were given olive oil in the study, and the mice that received the olive oil showed signs that the olive oil made their memory improve and lessened the signs of Alzheimer's. The researchers from this study plan to continue researching the effects of olive oil and Alzheimer's in older mice to see if they can eradicate the disease in mice altogether.
"When the team studied the brain tissue from both groups of mice, they noticed "dramatic" differences in nerve cell appearance and function. As compared to the mice that didn't consume the oil, the brain cells of rodents in the oil group showed a dramatic increase in nerve cell autophagy activation."

Animal Study Finds Monounsaturated Fats in Olive Oil May Extend Life
June 10, 2017 12:14 PM
A recent genetic study on metabolic changes has discovered an unexpected finding: accumulation of monounsaturated fats may lengthen one's lifespan. Though the study was conducted among roundworms rather than humans, it is interesting to note since researchers previously thought that decreased caloric intake would increase longevity. Rather, it appears that this particular build-up of fat and calories can be beneficial. The researchers discovered this by blocking certain DNA-modifying proteins to increase lifespan among worms, and then noted that these worms displayed higher levels of monounsaturated fatty acids.
"Prior research shows the type of fat consumed has a much greater influence on health than the quantity, and the recent experiment builds upon what is known on the topic."

Eating anti-inflammatory foods may reduce symptoms of rheumatoid arthritis
March 22, 2017 11:44 AM
As it happens your diet may have a significant impact upon the likelihood of Rheumatoid arthritis (RA) eating away at your joints as you age. 70% of white blood cells occupy the human intestinal tract - as RA is an auto-immune disease that turns the body's natural defenses against itself the link is worthy of further study. Several recent studies have made the connection between good diet (olive oil rather than butter) and RA incidence as well as severity and progression of the debilitating disease. The benefits of a good diet contrast with the current medical treatment prognosis for RA which actually weakens the immune system overall, opening the body up to any of a number of potential risk factors which eating right will strengthen the body's ability to resist.
RA is a life threatening disease which kills about 40,000 Americans annually and has a three to one preference to affect the female gender. A quarter of RA patients reported that a few specific dietary changes made noticeable impact, namely increasing blueberry and spinach consumption and reducing processed sugars.
"Recent medical research has suggested a strong link between the autoimmune illness rheumatoid arthritis and our food choices."

Omega Oils-What Are They For?
January 02, 2014 09:22 PM
What is all the hype about with these omega fatty acids?
Curious why they have become a huge talk of the nation, and such an important part of our diets all of a sudden? Some omega oils are essential for the growth of human tissue and proper body function, but our body don't produce enough of them on its own.
What is the difference between Omega 3's-6's-8's-9's?
Omega 3 is an essential fatty acid that is not produced by the body naturally. They're obtained from food sources, such as fatty fish, and flax-seed oil. They contain a number of health benefits for the body, such as reduced inflammation throughout the body, and have benefits for the heart. Studies have shown the reduced inflammation has a huge impact on heart health, and is highly recommended to incorporate into your daily diet.
Omega 6: is also an essential fatty acid that is not produced naturally by the body. These omega oils obtained from different types of vegetable oils, and through dietary supplements. Many claims made about Omega-6 fatty acids, however the only substantial proof is for heart health. They lower bad cholesterol levels, while raising healthy cholesterol levels. While essential, they are not to be overused, or they start being unhelpful by adding too much fat to the diet.
Omega 7's: are monounsaturated fatty acids, palmitoleic acid and vaccenic acid. Palmitoleic acids are commonly found in fat tissue of the human body, and in the liver. Animal oils, macadamia nut oil, vegetable oils, and marine oils are good sources of omega 7's. They're considered a beneficial fatty acid by increasing insulin sensitivity by lowering inflammation. They also aid in the destruction in of insulin beta cells in the pancreas. This action has been proven to reduce insulin levels, which have claims that omega 7's are helpful in weight loss. Other uses include support of healthy skin, and soothing the gastrointestinal tract.
Omega 9: fatty acids are not considered essential fatty acids since they're produced by the body. They're obtained from olive oil, and other monounsaturated fats. They contain the same heart healthy benefits as omega 3's and 6's helping lower cholesterol, our body makes them as needed.
Omega oils are important for our overall health, especially heart health. Omega 7s are important to control insulin levels, and may aid with weight loss. Supplementing omega 3, 6, and 7 can lead to better cholesterol levels, and healthier skin.
Diet To Lower Cholesterol
December 26, 2012 12:07 PM
Cholesterol is found naturally within the human body, particularly, in skin, internal organs, nerves, brain, cell membranes and bloodstream. This wax like compound is very important for the body's normal functioning. However, when there is excessive cholesterol buildup within the body, your health is at risk, because it gets deposited within the blood vessels. This article will talk about how to lower cholesterol levels through diet.
Consequences of Excessive Cholesterol Levels
Excessive cholesterol levels can cause dangerous ailments. Food habits as well as lifestyle changes are a few of the main reasons behind its rising level. Presented below are a few of the medical problems associated with high cholesterol levels within the body. When excess cholesterol is deposited on the inside of the arteries, flow of blood is interrupted which leads to inadequate supply of blood to the body. One of the organs that are mostly affected by high cholesterol levels is the heart. Extreme cases might lead to cardiovascular diseases such as heart attacks. Blocked arteries and reduced blood flow may lead to blood coagulation. Also, if blood supply to the brain is impaired, it can lead to confusion and stroke.
Research And Foods
Research has indicated that a diet which includes a daily consumption of oats, sterol based foods, nuts, soya based products and fish is extremely effective in decreasing the amount of cholesterol within the body. In fact, it is as effectual as taking cholesterol medication, and definitely a preferable as well as less costly option, with very little or no side effects. However, if you suffer from any special health condition, make sure you first speak with your healthcare professional before you go on a diet that is low in cholesterol. If you are currently taking some medication, you should check with your doctor to make sure the drugs are okay with the low cholesterol food.
Different Foods that Can Lower Cholesterol
Oats provides your body with soluble fiber that is beneficial in decreasing bad low density lipoprotein (LDL) cholesterol. Foods that contain oat bran, whole oat flour and oatmeal are extremely healthy as well as filling. Oat bran cold cereal and hot oatmeal porridge have been traditionally been eaten for breakfast, however you can include ground oatmeal to casseroles, baked foods and soups as well.
Nuts contain lots of fiber, protein, vitamins, polyunsaturated and monounsaturated fats, phytonutrients, antioxidants and plant sterols. They are not difficult to eat. All you need to do is remove the shell and put a handful in your mouth, lengthy preparations are not necessary.
Foods Rich in Soluble Fiber
You can keep your cholesterol levels low by regularly consuming foods that contain high amounts of soluble fiber. Soluble fiber adheres to cholesterol within the blood to flush it out. It also promotes healthy digestion.
Aside from oats, other examples of foods rich in soluble fiber:
Other foods that can lower cholesterol levels in the blood
However, you must bear in mind that even though eating foods that contain low cholesterol is definitely beneficial, these foods will not cure existing problems. Eating the foods mentioned above regularly in moderation and doing sufficient exercise is the secret to enjoying good health.
There are some supplements known to help lower cholesterol as well:
These are safe and effective ways to help reduce unwanted cholesterol.

Whether coconut oil is good for weight loss or not, it is becoming an increasingly popular component of a weight loss diet. So how justified is this in view the fact that fats and oils are not normally regarded as being the best form of food to take if you want to lose weight?
Apart from any other considerations, fats are actually very important components of any diet. Consider, for example, how many vitamins are fat soluble: vitamins A, D, E and K are all fat soluble, and without fats in your diet vitamins would not be able to circulate and be taken to where they do most good. Fats are also essential building blocks for hormones and cell membranes. In short, you cannot survive without fats. Coconut oil is a fat.
In referring to coconut oil here, we are discussing virgin oil, not the refined form that is high in cholesterol. Refined, or processed coconut oils, is hydrogenated, which renders it more in nature to the longer chain fatty acids. Virgin coconut oil contains what are known as medium chain fatty acids (MCFA), which are easily metabolized by your liver into energy.
The longer chain fatty acids, also called triglycerides, are not easily broken down into smaller components, and tend to be stored in the body as fat. This fat can be particularly dangerous if stored round the midriff, and so long chain fatty acids are dangerous to your health. This does not apply to MCFAs, and a possible mechanism for this is discussed later.
An inability to distinguish between the different types of fats and oils in your diet is largely due to a lack of education in the chemistry of fats, and the lumping together of all fats and oils under the 'fatty' flag. Perhaps it is the use of the word 'fat' for the overweight condition and the fact that the triglycerides and other chemicals are known generically as 'fats' that triggers a connection between the two, but although this is logical, and in some cases justified, it is not always the case. There are fats and fats, just as there are lubricating oils and greases, and edible cooking oils and greases.
The fatty acids in coconut oil are composed of relative small carbon chain lengths. Caprylic acid and capric acid contain 8 and 10 carbon atoms in the backbone compared to the 18 of the stearic acid that is commonly contained in animal fats. The longer the carbon chain in the molecule, the more difficult it is to break down, and the more likely it is to be stored in the body as a dense fatty deposit that places a strain on the heart.
Due to the shorter chain length the medium chain fatty acids hold less energy per unit weight. Apart from any other reasons then, coconut oil contains fewer calories than other fats and so if used as the bulk of your fat requirement, will be less liable to generate body fat. Not only that, but as inferred earlier, due to the smaller molecule these calories are more readily released as energy for use by your body rather than stored unused.
However, that is not the whole story on either count: coconut contains saturated fats, and also monounsaturated and polyunsaturated fats, although in small quantities. These, however, are present in only small amounts, although would still be expected to undergo oxidation and produce the rancid taste commonly found in aged unsaturated oils and fats. However, even after a year this does not happen, which indicates that coconut oil possesses some form of antioxidant properties. This is confirmed by the fact that people eating a diet rich in coconut oil has less of a need for the strong oil-soluble antioxidant vitamin E.
In fact, the metabolism of fats is usually connected with the carnitine transport system in the mitochondria, although the shorter chain fatty acids do not need carnitine for their metabolism. What happens then is that because carnitine promotes oxidation during stress, and causes oxidative damage to body cells, its absence in metabolism of coconut oil fatty acids results in a reduction in the oxidation that degrades unsaturated fats. Hence the lack of rancidity.
Taking this further, then, this lack of oxidation infers that those that take a diet rich in coconut oil (for example using it for cooking rather than animal and vegetable oils containing longer chain fatty acids) should be partially protected against cell oxidation in general. Oxidative effects such as aging, cardiovascular diseases and some cancers should be reduced, and studies have shown this to be the case. Those consuming coconut oil rather than other oils tend to age more slowly, suffer less from heart disease and tend to experience fewer incidences of cancer.
With regard specifically to weight loss, it is believed that consumption of medium chain triglycerides, as opposed to longer chain triglycerides, results in a higher rate of thermogenesis, or the conversion of carbohydrates to energy (fats are also carbohydrates). The first step in this process requires the presence of Coenzyme A in the form of the enzyme acyl-CoA-dehydrogenase, and measurement of the activity of this enzyme has indicated that medium chain triglycerides exhibit much higher expenditure of energy than the metabolism of long chain triglycerides when being converted to fatty tissue. However, though the energy used up in this reaction, known as lipogenesis, was higher, the formation of fatty tissue was the same.
Hence, MCA uses more energy to produce the same amount of fat as LCA, and therefore, although more energy is used up, no new fat is generated by the liver. Since your dietary fat intake can ultimately have only three fates: burned as energy, stored as the emergency energy source glycogen, or deposited as fat, then it is logical that the more energy generated then the less fat will be stored.
In this way, coconut oil, with a high content of medium chain fatty acids, has a scientific explanation for causing weight reduction when used as a source of fat in the diet rather than animal or other vegetable fats or oils. It is converted to energy rather than fatty tissue, and if you exercise to use up that energy then your weight loss can be significant.
What this theory also states, however, is that coconut oil should be used as a replacement for other fats, and not in addition to it. If you take coconut oil in addition to your normal diet, do not expect to see results.

DHA is a fatty acid that is essential for many body processes and structures. Fatty acids are the building blocks that create lipids, which are important nutrients that make up 25 to 45 percent of total body energy for most of those who are living in industrialized countries. The majority of dietary fatty acids are made from dairy products, meat, margarine, and vegetable oils.
Lipids are important because they store and transport energy from one part of the body to another and they also insulate and mechanically protect certain parts of the body. Any fat that is eaten is converted by the body into fatty acids, where it is then burned for energy, stored, or synthesized into other acids which are called prostaglandins. Some fatty acids are also vital structural components of cell membranes. DHA is part of a special class of highly concentrated, long-chained, polyunsaturated fatty acids called omega-3 fatty acids. Omega-3 fatty acids are looked at as one of the most fundamental molecules in the structure and activity of the membranes of all cells. They have a huge influence on the production of cellular regulatory compounds which are known as eicosanoids. They also are highly specialized in their function in neurological tissues, especially the retina of the eye. It is also very likely that omega-3s have specific and beneficial effects on the heart muscle, while they also influence the production of substances that control immune responses.
Fatty acids are short-chained, medium-chained, or long chained. Short-chain fatty acids are water-soluble and absorbed directly from the intestine into the bloodstream. They are generally used for immediate energy and can be found most abundantly in dairy products. Long-chained fatty acids are more emphasized when it comes to health concerns as they are stored in cell membranes and have a huge affect on membrane protein function. Their behavior in tissue membrane is what makes them greatly influential in health.
Besides the length of the chain, fatty acids are also described by their saturation. Saturation means how many hydrogen atoms the fatty acid carries. Fatty acids that carry as many hydrogen atoms as they can are called saturated fatty acids, while those that lose a pair of hydrogen atoms become unsaturated. This loss of hydrogen atoms creates a double bond between the two carbon atoms on either side of the missing hydrogen atoms. Those fatty acids that have one double bond are called monounsaturated fatty acids, while those with two or more double bonds are called polyunsaturated fatty acids. Most omega-3 fatty acids are highly unsaturated and have five or more double bonds.
EPA and alpha-linolenic acid are most commonly found in plant sources. DHA and EPA are made in phytoplankton, which is consumed by fish, mollusks, and crustaceans. The above reason is why these two essential fatty acids are found mainly in the aquatic food chain. LNA and EPA cannot substitute for DHA in all metabolic functions, even though DHA and EPA are more able to cover for each other in certain metabolic functions. It has been found that LNA is less effective than EPA which is less effective than DHA in enriching tissues, meaning that food sources such as vegetables and seed oils are not as good of sources than sea foods or other foods that are enriched with DHA and EPA. DHA in itself provides most of the health benefits displayed in research, to take essential oils that contain no DHA would limit the health benefits discussed above and from other sources. Have you had your DHA today?
Coconut Oil May Help Promote Healthy Thyroid and Digestive Function
November 01, 2007 09:49 AM
Coconut is extracted from coconuts, the coconut palm often being called the tree of life and for good reason. However, its benefits were lost to America for many years due to the politics of the vegetable oil industry claiming that all saturated fats are bad. This is not based on scientific or medical fact, and coconut oil was recently rediscovered in the USA, and the health benefits enjoyed by the rest of the world are once again available to Americans.
Coconut palms grow in most tropical climates such as Southern California and Florida, the Philippines and the Caribbean. Refined coconuts oils are mass produced and much of the beneficial nutrients are lost by the refining process. Virgin coconut oil is by far the better form, though is a slower process. It is generally obtained by shredding and dry milling the meat, and then cold pressing to produce the milk. The milk is fermented for a day or so and the separated oil collected.
Such oils are analyzed to contain over 50% lauric acid and high levels of phenolic antioxidants. Much higher than from refined oils. It is said to be the healthiest oil on earth. So why did the American authorities legislate against its use? It is because of the bad press received by saturated fats and oils.
You can have saturated, monounsaturated and polyunsaturated fats. The majority of the fats and oils in our diet are composed of long chain fats and oils. The chain length refers to the length of the hydrocarbon chain, whether saturated or unsaturated. It is long chain saturated acids that are bad for your cardiovascular system, and that should be avoided. However, there are also short chain and medium chain fatty acids that are more easily metabolized by the body. Coconut oil consists predominantly of medium chain fatty acids that help to protect against heart disease and cholesterol rather than promote it.
The highest levels of medium chain fatty acids are found in coconut oils and palm kernel oils, and these are far more nutritious than the saturated long chain fatty acids found in animal fats and just about all vegetable fats. The main MCFA in coconut oil is lauric acid.
Lauric acid is generally regarded as being responsible for the vast majority of the health benefits of coconut oil. The only other source of this fatty acid other than coconut oil is in human breast milk. After absorption, lauric acid is metabolized into monolaurin that is the monoglyceride used by the human body to destroy viruses and microbes, and attack the fat coated viruses that cause such diseases as HIV. It destroys flu viruses, a number of dangerous bacteria and protozoa such as giardia lamblia.
However, let’s have a look at some of the lesser known effects of coconut oil, such as its effects on the thyroid. Anything that blocks the efficient operation of the thyroid and secretion of the thyroid hormones can lead to excess estrogen in the body that can contribute to excessive blood cholesterol. There is a body of evidence that polyunsaturated fats and oils, such as soy, can have this effect is many people. When coconut oil is used instead, the medium chain fatty acids do not have the same effect, and those that are affected frequently find that their thyroid problem is cured and their blood cholesterol reduces.
This is not to infer that all hypothyroidism can be cured through the use of coconut oil, only those cases caused by consumption of excessive amounts of polyunsaturated fats. Although this is refuted by some medical practitioners that are against the use of supplements in general, it has been supported by medical evidence.
Coconut oil is also good for the digestion, and helps the cure of many digestive problems including Crohn’s Disease. It helps to build lipoproteins, fats and bile in the liver, the latter being essential for digestion. It helps to create a much healthier digestive tract that makes for generally better digestion and more efficient use of the foods you eat. Absorption of the nutrients is maximized and you feel altogether better in yourself when you take a small amount of coconut oil daily.
You can have sugar cravings for a number of reasons, and taking coconut oil can reduce these quickly and effectively, irrespective of their cause. The medium chain fatty acid breaks down and is rapidly metabolized to glucose thus providing a source of the energy your craving is telling you that you lack. It is very useful in reducing sugar cravings without you having to eat excess sugar that can create yeast problems.
If you replace the fats you are currently eating with coconut oil, it will not only act as an appetite suppressant but can also help you to lose weight. The fatty acids in coconut are absorbed immediately and converted to energy thus reducing your immediate need for food and hence your appetite. If you eat the saturated fat in coconut oil rather than the polyunsaturated fats in vegetable oils, then you can lose weight.
Many of the benefits of coconut oil are due to the speed with which the lauric acid is absorbed and metabolized in comparison to the long chain polyunsaturated fats. It is the chain length of the hydrocarbon tail that is important here rather than the number of double bonds in that chain that determines the degree of unsaturation.
Make sure that it is virgin coconut that you use since that is the most nutritious form. Do not be misled by labels claiming the contents to be extra virgin oil, since that is a term borrowed from the olive oil industry, and there is no such thing as extra virgin in relation to coconut oil. Never use refined coconut oil since that will just as bad for you as other saturated oils. Not even ‘Extra Virgin Refined Coconut Oil’ in the mistaken belief that such a label must indicate that the oil is extra good. It does not – it simply indicates that the supplier is a charlatan deliberately trying to mislead you into paying a premium price for a useless product.
Coconut oil may promote a healthy thyroid and digestive function, and all the medical tests indicate that it does. People that use it regularly swear by it and if you have a problem that virgin coconut oil might help, then one thing is sure: it will certainly do you no harm, and all indications are that it will do you a lot of good.
The Skinny on Fats - Omega-3, Omega-6, Omega-7, Omega-9
October 04, 2006 04:53 PM
Health experts keep changing the storey on fats. First we were told that polyunsaturated fats were better than saturated fats. Then it was discovered that refined polyunsaturates were favorite targets for free radical attack. Next, monounsaturated fats took center stage and have remained in the spotlight ever since. The Mediterranean Diet, with its high intake of olive and other oils high in monounsaturates, offers several important safeguards against cardiovascular disease, cancer and overall mortality. (Laino, de Largeril, Kokkinos, Trichopoulou). While monounsaturated fats are important for maintaining optimum health and smooth supple skin, it’s the kind of fatty acids and antioxidants they contain that make up the real story.
Dark green unrefined “extra Virgin” olive oil has a delightful full bodied flavor due to its natural antioxidants. Not only are the oils of various olive cultivars distinctive, they all help fight arterial plaque buildup. (Visioli) Olive oil has a long history in Europe as both food and medicine, and carbon dating of seeds found in spain have shown that the use of olive oil dates back 8,000 years. Gourmet chefs usually prefer particular oils for various uses in making dressing, marinades, and sauces for dipping. Olive orchards have now achieved a status second only to that of vineyards.
Macadamia nut oil is another designer oil that is fast gaining a reputation among chefs and health experts. The nuts originated in Australia where they were staples in the diets of the Aborigines. In 1881, they were introduced in Hawaii and in the 20th century, made their way to California where several cultivars are now grown. Like olive oil, macadamia nut oil is rich in antioxidants and contains the highest levels, greater than 80 percent monounsaturates, primarily polmitoleic (omega-7) than other oils. (Hiraoka-Yamamoto)
Macadamia nut oil products found in mass market are typically refined, with many of the antioxidants removed. The highest levels of antioxidants in macadamia nuts are found in the shells. During cold processing, some of these antioxidants leech into the oil, increasing its antioxidant potential. (Quinn) unrefined and organic oils have a golden color, pleasing nutty aroma and buttery flavor. Scientists have found that macadamia nut oil lowers, LDL cholesterol and triglycerides, and may help prevent stroke. (Yamori, Colquhoun) It is delightful on vegetables, in soups, on popcorn, and as a replacement for butter in baking.
The essential oils (Fish oils, flaxseed, GLA, DHA), which are available as liquid and packaged in black bottles, must be stored in the Refrigerator even when they have not been opened. You cannot heat or cook with them. Essential fatty acid supplements are convenient to take and have specific therapeutic value.
Cardiovascular and Nerves – Consumers have been advised to eat more fish rich in Omega-3 to reduce their risk of cardiobascular disease. However, experts worry that eating several servings of fish each week may not be safe especially during pregnancy, dursing or trying to conceive. Instead they recommend fish oil supplements such as Omega-3 from Algae , Fish oil, and Omega-6 Evening Primrose and Borage oils.
Pain Relief – A blend of cetylated fatty acids including myristate, myristoleate, laurate, oleate, palmitate and palmitoleate appear to be effective in reducing inflammation and pain in arthritis and other inflammatory conditions. (Vanderhaeghe) In a San Diego California study of sixty-four patients with osteoarthritis, an oral preparation of cetylated fatty acids known as celadrin significantly improved range of motion and flexibility. (Hesslink)
Two other studies of osteoarthritis patients at the University of Connecticut, using a topical preparation of Celadrin, showed significantly greater knee stability, improvement in stair climbing ability, balance and strength, and reduction of pain. (Kraemer)
Animal studies at the University of Minnesota have shown that cetylated fatty acids administered either topically or orally are well tolerated and rapidly dispersed throughout the body. (Gallaher) Doses for the oral form are 1500mg three times a day. The topical cream is applied two to four times a day.

Essential Fatty Acids - The “Good” Fats
June 25, 2005 08:24 PM
All About Fats
Some people shy away from anything that has the word “fatty” associated with it. They instantly think it will cause them to gain unnecessary weight. However, there are “good fats” and “bad fats,” and the beneficial ones can actually help decrease the desire to eat the harmful ones. Fats are important for health. Also known as lipids, they help balance the body’s chemistry and provide padding as protection for vital organs. Fats provide a source of energy for body processes, and they help with the transportation and absorption of fat-soluble vitamins such as A, D, E, and K. They are also a source of the vital nutrients known as essential fatty acids. Categories of fats include the following:
SATURATED FATS: All fats are composed of carbon, hydrogen, and oxygen molecules. The carbon atoms of fatty acids hold together in a chain-like fashion. These carbon atoms can attach hydrogen to them. When each place that can hold a hydrogen atom is filled and there is not room for even one more, they are described as saturated. The longer the chain, the harder the fat will be and thus, the higher its melting point. These types of long-chain fatty acids are found in “hard fats,” such as those in red meat, butter, cheese, sour cream and palm kernel and coconut oils. When a person’s diet is high in saturated fats, these fats tend to clump together in the body and form deposits, along with protein and cholesterol. They then lodge in the cells, organs and blood vessels. This can lead to many health problems, including obesity, heart disease, and breast and colon cancers.
UNSATURATED FATS: Unsaturated fats are called such because there are at least two adjacent carbon atoms on a chain which are not attached to hydrogen atoms. When at least two pairs of carbon atoms are empty it is known as a monounsaturated fatty acid. When two or more sets are empty, then it is referred to as a polyunsaturated fatty acid. A good rule of thumb is that the more saturated the fat, the more easily it will stay hard at room temperature.
ESSENTIAL FATTY ACIDS: Essential fatty acids (EFAs) are vital nutritional components that our bodies need for many functions. They are found in the seeds of plants and in the oils of cold-water fish. Essential fatty acids—sometimes referred to as vitamin F— cannot be made by the body; they must be sup-plied in the diet. However, at this time, the government has not officially established a Recommended Daily Intake (RDI). Many factors, including stress, allergies, disease, and a diet high in fried foods, can increase the body’s nutritional need for essential fatty acids.
Fats and Oils: Clearing the Confusion

Fats and Oils: Clearing the Confusion
By Fred Pescatore, M.D.
Aside from tax forms, it's hard to find anything more confusing to consumers than fats and oils. Fat-free diehards still don't know that fat is essential for the brain, hormones, cellular membranes: life itself. The clueless still use shortening, margarine and damaged grocery store vegetable oils. But what worries me more is that supposedly educated consumers aren't even getting it right. Should we be surprised since their doctors probably don't know the truth?
Mistakes made by your customers. They:
Let's clear up these myths so consumers can get busy being confused about something else:
I hope this helps you educate consumers about the proper use of fats. Unfortunately, that still leaves a long list of other things they've been misled about.
June 14, 2005 10:52 AM
Nutritional Scorecard by Sylvia Whitefeather Energy Times, June 15, 2004
For over 50 years, the federal government has produced Recommended Daily Allowances (RDAs) as guidelines for vitamin and mineral intake. Then, in 1993, the Reference Daily Intakes (RDIs) superseded the RDAs. By applying this new designation, the government's guidelines are now supposed to represent the designated amounts that an average person should consume. With this in mind, and the fact that many experts think you should consume more than some of the RDIs, how does your nutritional scorecard add up? Answering a few nutritional questions can point you in the right direction.
Are you trying to lose weight? If you are, the latest thinking on weight loss opines that eating more protein may be the key to keeping your weight down. Two recent studies published in the Annals of Internal Medicine (5/18/04) found that people who ate a low-carbohydrate, high-protein diet lost more weight and had better cholesterol levels than dieters who ate fewer fatty foods. Both studies found that a low-carb diet can improve your triglycerides (blood fats) and boost your HDL, or good, cholesterol.
Eating protein satisfies both tummies and taste buds. Researchers have found that the amount of protein eaten in a meal determines not only how much food you eat but also how satisfied you feel after eating (J Nutr 2004 Apr; 134(4):974S-9S). And when you feel satisfied after eating less food you improve your odds of losing weight.
We need about 50 grams of protein a day to support the body's functions. The best sources of protein are eggs, meat, milk, protein shakes and yogurt.
Does your energy level go up and down during the day? To get off the energy rollercoaster, cut down on carbohydrates, and make sure the carbs you do eat are complex.
Carbohydrates have been getting some unflattering press lately. Yes, if you want to lose weight, you may want to go on a strictly low-carb diet. But for those not concerned with weight, carbohydrates are the principle source of energy for the body.
What's more, even if you do restrict carbohydrates, you should still eat a tiny bit of them. Without some carbs in the diet your body cannot regulate protein or fat metabolism. According to Michael and Mary Eades, MD, authors of The 30-Day Low-Carb Diet Solution (Wiley), "Carbohydrates control insulin and insulin controls your metabolic health."
So, make your carbohydrates count. Indulge in complex carbohydrates: whole grains, fruits and vegetables. In those foods, carbs are accompanied by fiber and larger amounts of vitamins and phytonutrients. Other reliable sources of complex carbohydrates are whole wheat bread, brown rice and oatmeal.
Are you concerned about your heart health? Fiber from beans, oats, legumes, nuts, rice bran, fruits and vegetables helps stabilize blood sugar and reduce cholesterol. Pectins, found in apples, pears, prunes and plums, are a particularly useful form of water-soluble fiber.
Insoluble fiber, in cereals, wheat bran and vegetables, reduces the risk of colon-related problems. In addition to adding fiber to the diet, dried beans and soybeans have been shown to lower cholesterol, improve vascular health and kidney functioning, preserve bone mineral density and reduce menopausal discomforts (AJCN 1999 Sept; 70(3 suppl):464S-74S). Fiber also promotes good bowel health and encourages the growth of beneficial intestinal flora.
You need 25 to 40 grams of fiber daily. If you have cut back on your carbohydrates, be sure to take a reliable fiber supplement.
Do you have problems focusing on mentally challenging tasks? If so, you should eat more fish and get more of the omega-3 fatty acids that fish and flax contain. Higher levels of this type of fat have been linked to better concentration while performing demanding intellectual work (Lipids 2004 Feb; 39(2):117-23).
Fats add flavor to food, making meals taste better. Monounsaturated fats like plain olive oil and canola are liquid at room temperature and are suitable for use in cooking at high temperatures. Researchers have found that a diet high in monounsaturated fat has the ability to decrease LDL (bad) cholesterol (J Nutr 2001; 131:1758-63). Other fats, such as extra virgin olive oil and flaxseed oil, are best used in dishes that don't need cooking, such as salads.
Although the RDI for fat is less than 30% of the total calorie intake, some researchers believe that if you eat healthy fat, eating too much is not a concern. Omega-3 fats are available in supplement form.
Do you suffer from dry skin? You may not be drinking enough water. This precious liquid is used by every cell of our bodies and makes up 60% to 75% of our body weight. Water is important for kidney function. Researchers in Italy found that drinking adequate amounts of water can help prevent the formation of kidney stones (Urol Int 2004; 72 Suppl 1:29-33).
Your activity level, environment and diet influence how much water you need daily. Try to drink at least eight cups of fluid a day from noncaffeinated, nonalcoholic sources.
Do you exercise frequently? If you do, you need more antioxidant vitamins like natural vitamin E and vitamin C as well as a healthy supply of carotenoids. A study at the School of Applied Medical Sciences and Sports Studies, University of Ulster, found that exercisers need more antioxidants. Otherwise, their exertion may release an excess number of free radicals (caustic molecules) in their bodies and do damage to the heart arteries and other internal organs.
Vitamins, in general, are defined as micronutrients that are necessary for life. They are necessary for the production of energy, a healthy immune system and hundreds of other functions in the body.
Vitamins aren't the only substances that produce big benefits in small quantities. Phytonutrients are chemicals in plants that have health-promoting properties. These nutrients are getting more and more attention from researchers who are keeping score on our nutritional requirements.
Do your meals contain plenty of calcium? If not, you may need supplements to keep your bones strong and help keep your weight down. One study, presented at the Experimental Biology 2003 meeting in San Diego, found that young women who consumed more calcium had better luck controlling their weight. In this research, it didn't take much calcium to make a difference in waistlines. Consuming just one more serving daily (a cup of milk or a thumb-sized piece of cheese, each of which contain about 300 mg of calcium) made, on average, about a two-pound difference.
In addition, many experts recommend multimineral supplements (along with multivitamins) to promote better health. A recent study of people with immune problems, for instance, found that those kinds of supplements seem to help boost the immune system (AT News 2004 Feb 27; 398:4-5).
Cancer at the Millenium - the war on cancer entering its third decade...
June 13, 2005 10:23 AM
Cancer at the Millenium by Harriet Brown Energy Times, May 1, 1999
With the war on cancer entering its third decade, the necessity grows clearer for medical science to engage the enemy on several fronts. Until recently, high-tech medical weapons like vaccines and gene therapy, inspired by a flood of insights into the molecular basis of cancer, garnered most of the hope, hype, headlines and research money. The science was sexy and the prospect of a "cure" dramatic. But, today, advocates of prevention receive equal, if not greater, attention.
Improving our diets and prudently supplementing with vitamins and minerals, can deliver a major preventive impact. Contentious experts concede that at least a third (and probably more) of all cancers can be blamed on a combination of eating too much of the wrong foods and not enough of the right ones.
The Dietary Difference
Though cancer can progress rapidly once it leaps past its inception, it develops over many years and in several stages. Beneficial compounds in food and supplements may intervene along a line that runs from initial exposure to carcinogens to the final step into outright malignancy. Nutrients may: - counteract environmental poisons and the toxic byproducts of liver metabolism
The Big Picture The dietary guidelines advocated by the American Cancer Society and the National Cancer Institute (which generally coincide with those of most health organizations) may sound familiar: Eat plenty of fruits and vegetables. Get lots of fiber. Limit fat, especially animal fat. Go easy on meat and avoid the cured variety (they contain nitrites). If you drink alcohol, do it in moderation. Watch your total calories, and your weight. Pretty straightforward stuff.
Carotenoids, as their name suggests, are orange and red pigments in fruits and vegetables, most notably carrots and tomatoes, although they're also in everything from sweet potatoes to spinach and brussels sprouts (in the latter their distinctive color is masked by green chlorophyll).
Lycopene, a carotenoid found primarily in tomatoes, displays double the free radical-fighting activity of beta carotene, the most widely studied carotenoid. Of 72 studies looking at consumption of tomatoes or tomato-based products reviewed in the February 1999 Journal of the National Cancer Institute, almost half showed a significant reduction in one or more of a variety of cancers.
Research shows that lycopene may be best at lowering a man's risk of prostate cancer. A 1995 Harvard Medical School study (Journal of the National Cancer Institute 1995; 87: 1767-76) queried nearly 48,000 male health-care professionals about their consumption of fruits and vegetables. The only foods that reduced their risk of prostate cancer were, apparently, tomato sauce, tomatoes, pizza (tomato paste). For those who ate ten servings a week, risk dropped 45 percent; with four to seven servings, 20 percent. In animal studies lycopene decreased the number and size of mammary tumors (Eleventh International Symposium on Carotenoids, 1996).
Tomatoes are one of the richest sources of lycopene. Cooking tomatoes helps by releasing the lycopene from the plant cell walls. Also, the oil in tomato sauce enhances absorption in the stomach. Lycopene is also available in supplements.
Wine drinkers rejoiced when resveratrol, a constituent of the skin of red grapes, was found to protect their hearts (by blocking oxidation of LDL cholesterol and discouraging blood clotting). Now they have another reason to toast this potent antioxidant. When researcher John Pezzuto at the University of Illinois at Chicago screened about 1,000 plants for anticancer activity, he came up with one whose active ingredient turned out to be resveratrol. In lab tests it squelched both free radicals and inflammation, two well-known cancer inducers (Science, 6/10/97). In a study with mice, resveratrol reduced the number of skin tumors by up to 98 percent compared to control animals. Because the effective doses were high (Pezzuto estimates a person would have to quaff about five gallons of wine a day to get the equivalent) and because more than a drink or two a day may raise the risk of breast cancer, researchers don't recommend nondrinkers take up wine. But supplements of synthesized resveratrol (as well as grape juice) may help.
Saturated fat is an authentic dietary villain. Aside from clogging arteries, it's a suspected contributor to several cancers, though the evidence is greater for some cancers (prostate) than for others (breast cancer)
Of the two other main categories of fats, monounsaturated and polyunsaturated, mono seems benign, if not positively protective. For example, in a study of the influence of diet on breast cancer, Greek researchers discovered that women who consumed higher amounts of olive oil (which is mostly mono) were less likely to be afflicted with breast cancer (Journal of the National Cancer Institute 1995: 87; 110-116).
When it comes to polyunsaturated fats, however, things get complicated. The fat that predominates in corn, sunflower and other vegetable oils, called omega-6, has long been associated with cancer risk in animal experiments. Likewise the type found in margarines, trans fats, which are partially saturated vegetable oils. On the other hand, the omega-3 fats called EPA and DHA, which are found primarily in deep- and cold-water fish like cod, mackerel, and halibut, protect against both heart disease and cancer. In an epidemiological study covering 24 European countries, British researchers established that mortality rates for colon and breast cancers declined as fish and fish oil consumption rose (British Journal of Cancer 1996: 74; 159-64). And Finnish scientists discovered that the breast tissue of women who had breast cancer contained significantly less DHA and EPA than the breasts of healthy women (Nutrition and Cancer 1995: 24; 151-160).
Experts believe the omega-3s' anticancer effect derives from its ability to tamp down the prostaglandins that stimulate inflammation. Chronic inflammation unleashes a steady stream of free radicals, which can damage DNA and thereby trigger cancer. Omega-3s also help the liver detoxify potentially harmful substances.
Fortunately for the fish-phobic, nonmarine sources of omega-3 fats include flaxseed and hemp oils.
Minerals to Lower Cancer Risk
n Calcium: possibly protective against colon cancer. In a recent trial (New England Journal of Medicine, 1/14/99) researchers gave people with a history of precancerous colon polyps either two 600 mg calcium tablets a day or a placebo for nine months and found fewer polyps. n Selenium: powerful antioxidant and supporter of immunity. Researchers find that cancer rates in various regions is lowered when soil and vegetables contain more selenium
In a selenium-depleted area in China afflicted with one of the highest incidences of stomach and esophageal cancer mortality in the world, scientists asked different groups to take various combinations of nutrients. After five years they found a significant reduction in the cancer rate among those who had gotten supplements of selenium, vitamin E and beta carotene (Biological Trace Element Research 1985; 7: 21-29). In the U.S. researchers studying the potential effectiveness of selenium supplementation for preventing nonmelanoma skin cancers came up with a surprise. The 200 mcg a day the subjects received for an average of 4.5 years had no impact on skin cancer but did significantly cut the rates of lung, colorectal and prostate cancers (Journal of the American Medical Association, 12/25/96).
More recently Harvard researchers determined that men with prostate cancer had much lower levels of selenium in their toenails (a measure of consumption) than healthy men (Journal of the National Cancer Institute, 8/119/98).
Cruciferous vegetables like broccoli, brussels sprouts, cauliflower and kale, have long been singled out for their association with protection against cancer. In a 1996 survey of 94 population studies and clinical trials focusing on consumption of cruciferous vegetables, 67 percent showed a reduced risk, the strongest link being with lung, stomach, colon and rectal cancers (Cancer Epidemiological Biomarkers 1996; 5: 733-748).
Scientists at Johns Hopkins showed that sulforaphane, from these plants, stimulates enzymes that help detoxify carcinogens generated in the liver. When they injected rats with a cancer-causing chemical, only 26 percent of the rodents pretreated with sulforaphane developed mammary cancer, compared to 68 percent of controls. Even animals who did come down with cancer had tumors that appeared later and smaller.
Other researchers have focused on a cruciferous-vegetable compound called indole-3-carbinol, which has proved especially effective against breast cancer cells. Recently, scientists at the University of California at Berkeley found that indole-3-carbinol, rather than acting as an anti-estrogen, (as had been thought), actually stops breast cancer cells by turning off a protein critical to their replication (Jrnal of Bio Chem, 2/13/98). Consequently, when treating certain forms of cancer, some doctors have paired indole-3-carbinol with the chemotherapy drug tamoxifen - which counteracts estrogen - and found that the combination has proven more potent than either separately.
Several decades ago British physician Denis Burkitt proposed that the low incidence of colon cancer among native peoples in South Africa was attributable to the fact that their diet was rich in fiber. The fiber, it was hypothesized, bulked up the stool, speeding its passage through the bowel and reducing the time carcinogens contact its lining; it also helped neutralize cancer-promoting bile acids.
This concept has been backed up by numerous studies. Recently, Harvard researchers sprinkled cold water on this idea, finding that an examination of the eating habits of more than 80,000 female nurses, could find no protective effect against colon cancer or precancerous polyps from consuming fiber (NEJM, January 21, 1999). Most experts' take on this apparent refutation: Maybe the "high fiber" intake in this case wasn't high enough, and this is just one study among many.
Fighting Breast Cancer
Fiber has also been linked to reduced rates of breast cancer. At first it was thought that if fat was a breast-cancer culprit, fiber might just be a marker for a low-fat diet. But a look at Finland undermined that idea: Finnish women eat both a lot of fat and a lot of fiber, and their breast cancer rate ranks much below that in the U.S., (where we eat gobs of fat and little roughage).
Fiber helps take estrogen out of circulation as it passes through the liver, while the isoflavones in many high-fiber plants and vegetables are themselves weak estrogens, which compete for slots on breast tissue's estrogen receptors. The special fiber in flaxseed oil called lignans act against estrogen in two ways: by binding its receptors and by inhibiting the enzyme that converts other hormones into estrogen.
Fiber comes in two basic forms, insoluble (e.g., wheat bran, celery, the skins of fruits and vegetables) and soluble (e.g., oat bran, citrus fruits, beans). Until a few years ago, scientists believed that cancer protection came mainly from insoluble fiber, but that thinking has turned around.
A soluble fiber called citrus pectin has been shown to halt the tendency of prostate, lung, breast and skin cancers to metastasize, or spread (e.g., Journal of the National Cancer Institute 1995; 87: 3448-353). Typically cancer turns deadly only when it gets into the bloodstream and invades new territory. Modified citrus pectin appears to stop this aggression by preventing cancer cells from attaching to healthy tissue.
While the name inositol hexaphosphate (IP6) sounds like a mouthful, many of us consume mouthfuls of this natural substance every day - in foods like corn, rice, whole-grain cereals, oats and wheat.
But now scientists have isolated IP-6 and found that this powerful antioxidant can slow the destructive cellular processes that lead to tumors. In a study published in Anti-Cancer Research (Nov/Dec 1998), scientists at the University of Maryland School of Medicine demonstrated that IP-6 could shrink liver tumors in laboratory animals.
The researchers believe that IP-6 can help prevent cancer and also be useful in lowering the risk of health problems like kidney stones and heart disease. Research like this continues to expand our knowledge of how to lower the risk of cancer. In the next millennium, with more and more information making its way into the media and onto websites, our power and the responsibility to reduce our risk of cancer will continue to grow and offer new possibilities.
Fats for Life - the quality of the fat you eat is probably much more important than the...
June 12, 2005 02:39 PM
Fats for Life by Henry Wolfe Energy Times, August 6, 2003
For years, many experts argued that the only good fatty foods were the ones you didn't eat. That was a big, fat mistake. Overwhelming evidence now shows that certain fats are not only necessary for optimal health, but that the quality of the fat you eat is probably much more important than the quantity.
Threatening Trans Fats
"The biggest thing wrong with the fats Americans eat today is that they are eating too many trans fatty acids," says Fred Pescatore, MD, author of The Allergy and Asthma Cure (John Wiley). "About 42,000 foods contain trans fats. These fats are linked to a higher risk of heart disease, stroke and cancer."
Trans fatty acids are fats that form when food manufacturers add hydrogen to fat molecules, a process called hydrogenation that makes fats stay fresh longer without growing rancid. Trans fats also form when foods are fried.
Hydrogenation extends the shelf life of refined foods like cakes, donuts, and crackers. Unfortunately, it also creates fats that many experts believe can compromise your health. In a study of the health effects of trans fats, 26 people agreed to eat a diet that changed every five weeks, continually shifting the types of fats in their meals (American Heart Association's Scientific Sessions 2000). All of the diets in the study provided 30% of calories from fat. One fifth of the fat came from either soybean oil, semi-liquid margarine, tub margarine, shortening, stick margarine or butter.
"We were interested in assessing what would happen when we substituted one fat for another," notes researcher Alice H. Lichtenstein, DSc, professor of human nutrition at Tufts University, Boston.
The study showed that as people ate more trans fatty acids (in the more solid margarines) and fewer polyunsaturated fats (in the liquid oils), their triglycerides increased after each meal. Triglycerides are blood fats that boost heart disease risk.
For instance, when these folks ate stick margarine, which is high in trans fats, their triglycerides climbed an average 18% higher than when they ate semi-liquid squeeze bottle margarine, a type of margarine that is softer because it is less hydrogenated. Stick margarine raised heart disease risk by causing a drop in HDL, or "good" cholesterol. Although butter increased HDL, it also caused a significant increase in LDL, the "bad" cholesterol that raises heart disease risk.
"The best dietary advice we can give people is to minimize their intake of animal and hydrogenated fats in order to reach the American Heart Association's target of 10% or less of total calories from saturated fat and trans fatty acids," Dr. Lichtenstein says. "That would mean consumers choosing low-fat and non-fat dairy products and lean cuts of meat, and the food industry decreasing the amount of hydrogenated fats used in their products." According to a study at Johns Hopkins University (Amer Coll of Card, 52nd Scientific Session, 3/30/03, Chicago), people who eat saturated fat have more visceral fat, fat surrounding their internal organs. This fat around the waist is now seen as a risk factor for heart disease and other illnesses.
Another hidden problem in our fat consumption, according to Dr. Pescatore, hides within canola oil. Dr. Pescatore says that although many consumers believe canola oil is beneficial to health, the refined canola oil sold in the US has had its potential health benefits removed during processing.
"People still think canola oil is healthy and eat too much of it," he says. "The problem with canola is that it is highly processed and refined....Processors hydrogenate canola oil to keep it from getting rancid."
According to Fred Ottoboni, PhD, coauthor of The Modern Nutritional Diseases (Vincente Books), "Canola oil is lightly hydrogenated to take out the omega-3 fatty acids (the healthiest, but most unstable, fats) and then the food manufacturers filter the trans fats out. I don't worry about the trans fats in canola, but the problem is the huge ratio of omega-6 fatty acids to omega-3s."
To get more of the omega-3 fatty acids, which are lacking in most Americans' diets, Dr. Pescatore advocates using macadamia nut oil. "Macadamia nut oil is higher in monounsaturated fats than olive oil; it is the healthiest fat with an omega-3 to -6 ratio of one to one."
The Omega-3 Difference
Omega-3 and omega-6 fatty acids are basic forms of fat found in oils. Fish oil, hempseed and flax oil are high in what are called omega-3s. Certain plant-derived oils like corn and soy are richer in omega-6 fatty acids.
"Primitive humans ate a diet that contained a one-to-one ratio of omega-3s and omega-6s," says Dr. Pescatore. "Today we (Americans) eat 20 times more omega-6 than -3; that's why we suffer so much chronic disease and chronic inflammation. For instance, the Japanese eat a (much better) diet that contains a two-to-one ratio of omega-6 fatty acids to omega-3." "Not all omega-6s are bad," he adds, "we just eat too many of them."
Switching to healthier fat isn't hard. Eat more fish. When cooking, stick to oils like olive oil and macadamia oil. The quality of your oil and your health may improve in a big, fat way.

The cholesterol story packs enough subplots to satisfy a soap opera. There's Cholesterol: The Good, the Bad and the Awful. Cholesterol: The Stalker Behind Every (Restaurant) Door. Cholesterol Steals Your Heart Away-to the Mediterranean.
The very image of cholesterol chills the imagination. Lurid and unsavory, it would seem to bob through the bloodstream like blobs of fat congealed on cold soup, slathering itself onto arteries.
Cholesterol is in fact a normal, natural substance in our bodies, found in the brain, nerves, liver, blood and bile. Cholesterol is so crucial that each cell is equipped with the means to synthesize its own membrane cholesterol, regulating the fluidity of those membranes when they are too loose or too stiff.
We manufacture steroid hormones-the female hormones estrogen and progesterone, and the male hormone testosterone-from cholesterol. Adrenal corticosteroid hormones, which regulate water balance through the kidneys, and the hormone cortisone, the vital anti-inflammatory that also governs our stress response, come from cholesterol. Other jobs of cholesterol: production of vitamin D and bile acid (for the digestive process); healing and protecting skin, and antioxidant compensation when vitamin and mineral stores are low.
How can mere mention of this invaluable component in our body chemistry make our blood run cold?
Guilt by Association
Cholesterol's reputation as a bad character actually originates in the crowd it runs with: the lipoproteins, protein molecules to which it binds in order to travel back and forth through the bloodstream to the liver, where it is manufactured.
Not really a nasty round glob of fat at all, cholesterol is a crystalline substance, technically a steroid, but soluble in fats rather than water, thus classified as a lipid, as fats are. Thousands of cholesterol molecules bind with lipoproteins, spherical fat molecules that transport them through the bloodstream.
Three different kinds of lipoproteins participate in this necessary process, not always with the same salutary effect. Here's how they work:
High-density lipoprotein (HDL): referred to as the "good cholesterol." Carries relatively little cholesterol. Travels through the bloodstream removing excess cholesterol from the blood and tissues. HDLs return the surplus to the liver, where it may once again be incorporated into low-density lipoproteins for redelivery to the cells.
Low-density lipoprotein (LDL): the so-called "bad cholesterol," heavily laden with cholesterol, hauling it from the liver to all cells in the body.
Ideally, this system should be in balance. But if there is too much cholesterol for the HDLs to pick up, or an inadequate supply of HDLs, cholesterol may aggregate into plaque groups that block arteries.
Lipoprotein(a), or Lp(a): the "really bad" cholesterol, can step in, providing the glue that actually sticks to the arterial wall. Lp(a) is an LDL particle with an extra adhesive protein wrapped around it, enabling it to attach fat globules to the walls of blood vessels. The potentially deadly results are atherosclerotic ("plaque") deposits. Simple LDL lacks adhesive power and presents little risk for cardiovascular disease.
Researchers confirmed the existence of Lp(a) in the August 1996 issue of the Journal of the American Medical Association, disclosing that high levels of Lp(a) in the blood can double a man's risk of heart attack before age 55. Doctors estimate that about 20% of all Americans carry elevated levels of Lp(a).
One troubling aspect of the report, part of the ongoing 40-year-old Framingham Study, concerned the fact that the men who suffered heart attacks entered the project with no signs of heart disease and only slightly elevated cholesterol.
But during the 15-year investigation, 129 men out of 2,191 developed premature heart disease.
The culprit? High levels of Lp(a)
Experts don't know for certain where Lp(a) comes from, or its normal function, although they suspect the body's quotient of Lp(a) is mostly due to your genes. According to the study, they also believe that aspirin, a blood thinner, and red wine (or its grapeseed and skin extracts) may mitigate the damage of Lp(a). That also would explain why the French, who tend to wash down their fat-rich diet with red wine, experience a relatively moderate incidence of cardiovascular disease
The Terrible Triglycerides
The body also transports fats via triglycerides (TGs), the main form of body fat and the storehouse for energy. Edible oils from seeds, egg yolk and animal fats also are composed chiefly of TGs. Although not as corrosive as LDL, excess TGs intensify heart disease potential when they oxidize and damage artery linings or induce blood cells to clump.
An "acceptable" level of triglycerides is thought to be 200 milligrams, although under 150 is probably healthier. And some researchers think your triglyceride reading should be below 100. High triglycerides and low HDL often occur together, increasing the risks of cardiovascular disease, high blood pressure, heart and kidney failure and other degenerative diseases.
What To Do About Your Cholesterol
Have it checked. High cholesterol alone shows no symptoms. Your health practitioner can perform a laboratory test to measure your levels. Thoroughly share your own medical history and as much as you know about your family members: heredity and related illnesses definitely are important influences. People with diabetes, for example, can have high levels of triglycerides, which also may lead to pancreatitis (painful inflammation of the pancreas) at extremely high levels.
According to the National Cholesterol Education Program, a reading of under 200 mg/dL is desirable; 200 to 239 is borderline high; 240 and above is high. Your LDL level should be 130 or under; HDL should not be lower than 35. A triglyceride level below 200 is considered desirable; readings above 400 are high.
Adjust your diet. Cholesterol levels are readily controllable, primarily through changes in your diet. Leslie C. Norins, MD, PhD, suggests all-out war in his Doctor's 30-Day Cholesterol Blitz (Advanced Health Institute) with saturated fats, which raise cholesterol more than any other component in your diet, as your number-one target. Out with saturated fats like butter, cheese, whole milk, ice cream, red meat and some vegetable fats found in tropical oils like coconut and palm; in with fruits, vegetables, brown rice, barley (a good source of soluble fiber, the kind that soaks up fats and cholesterol and escorts them out of the body), beans, potatoes and pasta, prepared or dressed with monounsaturated fats in olive and canola oils (the so-called Mediterranean diet concept). Feast on cold-water fish (mackerel, salmon, sardines and herring) rich in omega-3 fatty acids that help reduce serum lipids, among many other healthful advantages.
Exercise. Move it and lose it are the words to live by when it comes to cholesterol. Researchers from the Stanford Center for Research in Disease Prevention reported in the July 2, 1998 New England Journal of Medicine (vol. 339, pages 12-20) that a weight-loss diet like that of the National Cholesterol Education Program plus exercise significantly lowered LDL (bad) cholesterol levels for men and postmenopausal women. The diet alone failed to lower LDL in these folks with high-risk lipoprotein.
Educate yourself. In addition to your health practitioner, books and magazines can guide you in cholesterol management. A trove of information is the National Cholesterol Education Program (NCEP), launched in 1985 by the National Institute of Health.

Take it to Heart - Lower Cholesterol

Take it to Heart by Dawn Lemonathen Energy Times, January 2, 2002
Lifestyle is key to bettering your odds of beating heart disease. A few simple, everyday heart-friendly habits can help your heart help you. Right now, heart attacks and other cardiovascular complications like stroke have reached sky-high levels across the US.
Nearly 60 million Americans suffer from one of the various forms of cardiovascular disease and these often fatal complications cause more than 40% of all deaths in the United States. Statistics show that nearly a million Americans succumb to heart problems every year. The humongous cost: Heart disease and stroke consume almost $260 billion annually. Heart disease is the top cause of death for older Americans and remains the leading cause of death for all Americans age 35 and older. Coronary heart disease (CHD), also known as ischemic heart disease, is the most frequent cause of death for adults in the United States-accounting for more than 500,000 deaths a year. And even though most women have had their consciousness raised about their risk of cancer, particularly breast cancer, in fact, their chances of dying from one of the forms of heart disease is double their risk of succumbing to one of the forms of cancer. And ten times more women die from cardiovascular problems than die from breast cancer.

Essential Fatty Acids - Lipids, Cell Memgranes & Eicosanoids
June 09, 2005 09:35 AM
Essential Fatty Acids and Phospholipids
Essential fatty acids & phospholipids are primary constituents of cell membranes, and as such they are vital to the makeup of the human body. Essential fatty acids are used to generate certain intra-cellular hormone-like substances, including prostaglandins and leukotrienes, which are responsible for regulating key bodily processes. Source Naturals essential fatty acid supplements are potent, effective and chemical-free.
LIPIDS, CELL MEMBRANES & EICOSANOIDS
Almost by definition, life is composed of cells, and cells are defined by membranes. One theory suggests that, around four billion years ago, self-replicating molecules, similar to the ribonucleic acid or RNA in our own cells, were synthesized from organic molecules. These self-replicating molecules adapted to changes in their environment to increase their potential for survival. Thus began the process of evolution that has led, over the eons, to us. One turning point was when these molecules developed membranes - envelopes which could help concentrate chemicals needed for the cell's survival. There existed in the "primordial soup" substances uniquely suited to this purpose: a class of organic compounds we call lipids . Lipids are more commonly called fats, and in this health and image-conscious age people often think of them as something to be avoided. However, the word fat refers to a variety of substances with a diverse range of chemical properties, which are essential for survival and well-being . The simplest lipids, fatty acids such as palmitic acid, consist of a hydrocarbon "tail" connected to a carboxyl group (COOH). The majority of lipids in food and in the human body occur in the form of triglycerides - a molecular configuration in which three fatty acid chains are attached to a 'backbone' of glycerol (an organic alcohol composed of a 3-carbon chain with an alcohol group attached to each carbon). The major roles of lipids can be described as energy and storage, structural, and metabolic.
Energy and Storage
Molecules can contain more or less chemical energy. In living systems most of the energy needed to drive chemical reactions is derived from oxidation. Oxygen, the ultimate electron acceptor, is a strong oxidant: it has a marked tendency to attract electrons, becoming reduced in the process. When a molecule undergoes a chemical reaction from a high-energy reduced state to a low-energy oxidized state, energy is released. This is what happens in a fire: the high-energy carbohydrates in wood, such as glucose, react with oxygen, releasing heat and the low-energy molecules of carbon dioxide and water. This is similar to what happens in metabolism.
Most of the carbon in a fatty acid chain is highly reduced, which makes fats more energy-rich than the other organic molecules that can be burned as food. This is what we mean when we say fats are high in calories - a measure of the amount of energy released when a substance is oxidized. Fats contain more than twice as many calories as carbohydrates. This makes fats an important storage fuel for most of the body.
Another important class of lipids in the human body consists of the phospholipids. Like triglycerides, phospholipids contain fatty acid chains- in this case two, one saturated and one unsaturated, attached to a glycerol backbone. Unlike triglycerides, in phospholipids the third carbon of the glycerol molecule is attached to a phosphate (a molecular group that contains phosphorus and oxygen), which is in turn attached to either an amino acid or, in the case of phosphatidyl choline, a molecule of the B-vitamin - like substance, choline.
Their unique molecular structure makes phospholipids amphipathic, which means 'likes both':
Fats, being hydrophobic, tend to separate out from water. When fat is mixed with phospholipids in the presence of water, the phospholipid molecules attach themselves to the molecules of fat and bring them into the water solution, enabling the fats to dissolve in water.
Phospholipids form a structure called a lipid bilayer, a two-ply sheet of phospholipid molecules in which the hydrophilic head groups face outward and are in contact with the water, and the hydrophobic tails face each other on the inside of the bilayer. This structure is one of the key constituents of the cell membranes that surround every living cell.
The lipid bilayer of cell membranes is a fluid in which membrane-embedded proteins "float." These proteins serve a wide variety of different functions. Some are enzymes, serving to carry out chemical reactions in the adjacent solution. Some are involved in signaling, in which a biochemical action in a cell is 'commanded' by means of a hormone or some such other signaling molecule. Still others are involved in transporting substances across the membrane, into or out of the cell.
The functions of membrane-embedded proteins are dependent on a very precise balance of phospholipids for their function. Phosphatidyl serine, for instance, has a negatively-charged head group that associates preferentially with a class of membrane-bound proteins called ATPases. ATPases regulate, among other things, the balance of sodium and potassium in intra- and extracellular fluids, a balance that is necessary for the integrity of our cells and also for the electrochemical impulses that make up our thoughts and feelings. Without phosphatidyl serine, these vitally important membrane-embedded proteins could not function.
Cholesterol is a waxy substance that is essential to the structure of cell membranes, which depend for their function on a delicate balance between fluidity and solidity. Cholesterol provides a semifluid matrix, as well as enhancing membrane fluidity. About 80% of the cholesterol the body uses is manufactured by the liver; the other 20% is consumed in food. Elevated blood cholesterol levels are associated with heart disease. Saturated fats are converted into cholesterol more readily than unsaturated fats, and polyunsaturated fats usually depress blood cholesterol concentration to some degree. Researchers have thus recommended that people lower their consumption of saturated fats and increase their consumption of polyunsaturated fats. A process called hydrogenation , in which hydrogen molecules are added, is used to harden these unsaturated fats to create solid spreads, such as margarine. This process causes formation of altered fats called trans fatty acids. Although the results are not conclusive, human and animal studies have pointed to possible deleterious effects from consumption of trans - fatty acids, which are estimated to account for 5.5% of all fats consumed by Americans. These studies include one in men and women that showed harmful effects of trans - fatty acids on blood cholesterol ratios.
When each link of a fatty acid chain contains an atom of hydrogen, as in palmitic acid, that fatty acid is said to be saturated . If two carbon links are double bonded to each other, each has one less hydrogen atom, and the fatty acid chain is said to be unsaturated. If a fatty acid contains one double bond, it is said to be monounsaturated, and if it has two or more double bonds it is said to be polyunsaturated . Certain polyunsaturated fatty acids cannot be manufactured by the body and must be obtained from the diet. These nutrients are called essential fatty acids and are necessary for the normal function of all tissues. The essential fatty acids fall into two categories:
In addition to being phospholipid precursors, essential fatty acids can be converted to a class of hormone like intracellular messengers called eicosanoids. The physiologic effects of eicosanoids are potent in minute quantities. Their effects are so powerful that they need to be produced near the site of their action and are quickly inactivated. The important eicosanoids include the thromboxanes, leukotrienes and prostaglandins (PGs ). Prostaglandin molecules consist of a five-carbon ring with two side chains. They can be distinguished from each other by numbers that refer to the number of double bonds in their molecular side chains: 1-series PGs have one double bond, 2-series have two double bonds, and so on. Prostaglandins mediate a variety of bodily processes, including inflammatory reactions, blood vessel contraction and dilation, and platelet aggregation. The different PGs have different effects on the body, and different essential fatty acids act as precursors for different PGs.
Important essential fatty acids in humans are the omega-6 fatty acids, which include linoleic acid (LA), gamma-linolenic acid (GLA), and arachidonic acid (AA). 1-series PGs are derived from GLA and tend to cause blood vessels to dilate and reduce the stickiness of platelets (cell fragments in the blood that help initiate blood clotting). 2-series PGs are derived from arachidonic acid and tend to increase platelet stickiness and cause blood vessels to constrict. Meat and dairy products are dietary sources of the PG2 precursor, arachidonic acid; American diets tend to be rich in these foods. The rate-limiting step for production of GLA in the human body is an enzyme called delta-6-desaturase (D6D). The action of this important enzyme can be blocked by a number of different lifestyle factors, including a diet high in saturated or trans- fatty acids and chronic alcohol consumption. A modest increase in consumption of GLA will significantly increase the ratio of GLA to AA in the tissues, which may have a beneficial effect on the homeostasis of the cardiovascular system. Supplementation with omega-3 fatty acids, such as flaxseed oil or fish oil, is beneficial for similar reasons. Omega-3 fatty acids are precursors for 3-series PGs, which reduce platelet stickiness. Series-3 PGs also tend to inhibit conversion of AA into its metabolites, the 2-series PGs.
The lipid composition of our diets has changed radically in the 20th century. Our intake of saturated fats has increased dramatically, and trans fatty acids, which did not exist before the advent of modern food processing technology, now form a major part of our diets. We eat less fish and green leafy vegetables, important sources of omega-3 fatty acids, than our ancestors did. Far from being an inert, homogeneous substance, fat is dynamic and varied - a subtle and interactive matrix for many of the biological processes taking place in our bodies, minute by minute.
Gluco Sciense - Take Control of your Blood Sugar ...
June 02, 2005 10:51 AM
Sedentary lifestyles, obesity, and sugar-rich diets are prevalent in our society. The result: challenges to your multiple, interdependent body systems involved with blood sugar levels and insulin activity. Now is the time to learn how a healthy diet and lifestyle can help you maintain healthy blood sugar levels. For further support, Source Naturals offers you GLUCO-SCIENCE™, a breakthrough formula. GLUCO-SCIENCE is uniquely effective because it is a Bio-Aligned Formula™. Source Naturals evaluates the underlying causes of system imbalances. Then we design formulas that provide targeted nutrition to bring your interrelated body systems back into balance. GLUCO-SCIENCE can help bring your body’s systems for carbohydrate metabolism back into alignment.
A Bio-Aligned Formula™
GLUCO-SCIENCE is a comprehensive herbal-nutrient formula, based on the newest clinical research into key herbs and special ingredients. Source Naturals studied the scientific research, and then designed GLUCO-SCIENCE. This Bio- Aligned Formula provides targeted nutrition to five different body systems involved with healthy blood sugar levels and insulin activity.
GLUCO-SCIENCE supports glucose/carbohydrate metabolism with a range of nutrients. B-vitamins are required for glycolysis and the Krebs cycle, the metabolic pathways by which the body converts glucose into cellular energy. Chromium is believed to work closely with insulin to facilitate the uptake of glucose into cells. Manganese is also involved in glucose uptake. The formula also features herbs from several traditions, such as Gymnema sylvestre.
Insulin is secreted by the pancreas in response to high blood glucose levels after meals. Without insulin, glucose cannot enter cells to provide fuel for cellular energy. Certain nutrients (see chart) support these vital metabolic processes, including mediation of insulin release and activity, and enhancing insulin sensitivity. N-acetyl cysteine protects pancreatic beta cells from oxidative damage in animal studies. In addition, vanadium, zinc, and selenium are notable for their insulin-like actions.
Heart and Circulatory System
Vitamin E supports a healthy lipid status, while myricetin has been shown in animal studies to influence triglyceride levels. Gymnema sylvestre and vitamin C are involved with lipid metabolism. Additional heart-healthy ingredients include CoQ10, garlic, fenugreek, and hawthorn.
Antioxidants are important for a healthy nervous system. Lipoic acid helps prevent lipid peroxidation, which can impact nerve function. Many B-vitamins are vital to the metabolic processes of the nerves or are present in the phospholipids of cell membranes. Methylcobalamin, an active form of vitamin B-12, supports the central nervous system. Other supportive ingredients are included (see chart).
GLUCO-SCIENCE provides antioxidants, nutrients and herbs with an affinity for eyes and the physiological processes involved in sight. Alpha-lipoic acid, quercetin, and vitamin C support healthy lens function. Bilberry, shown to support microcirculation in animal studies, is widely recognized for supporting vision.

Improve Your Diet and Stop Being S.A.D.

Improve Your Diet and Stop Being S.A.D.
The Standard American Diet (or S.A.D.) is exactly that ? sad! Sadly lacking in essential nutrients and sadly loaded with an excess of the wrong things, like fat, cholesterol, salt and sugar. How can we improve our diets and truly nourish our bodies?
Eat More Fruits and Vegetables
Why are fruits and vegetables so important? Not only are they high in vitamins and minerals, but they also contain bioflavonoids?naturally occurring plant constituents that act as antioxidants and support the integrity of our connective tissue. And fruits and vegetables are high in fiber, so crucial in maintaining our digestive tract health.
What fruits and vegetables don't contain is just as important as what they do contain: fruits and vegetables are free of cholesterol, additives and preservatives, contain no added sugar or salt, and are low in fat?nature's perfect foods. All you have to do is look at the bright, crisp colors?the vibrant greens, yellows, oranges, reds and purples?to know how good fruits and vegetables are for you.
Eat More Whole Grains
Whole grains, like oats, brown rice and barley, help us meet important nutritional goals. They are low in fat and high in fiber, and, because the germ of the grain has not been lost in the milling process, they are higher in essential fatty acids, vitamin E and B vitamins compared to processed grain products like white bread or pasta. And they're delicious! Have a bowl of hot oatmeal with fresh fruit and nuts for breakfast?or make a hearty barley-vegetable stew for dinner. Your body will thank you!
Increase Your Fiber Consumption
Fiber exercises our digestive tract?toning and strengthening the muscle that surrounds our intestines just the way lifting weights tightens and tones our skeletal muscles. Low-fiber diets increase our risk for a variety of bowel problems, from constipation and hemorrhoids to diverticulosis and diverticulitis to colon cancer. Increasing fiber in the diet is good for the digestive tract, helps regulate blood sugar and may also help reduce cholesterol levels.
What are the best dietary sources of fiber? All plant foods (whole grains, legumes, fruits, vegetables, nuts and seeds) contain fiber. And all animal products (meat, poultry, fish, eggs and dairy products) contain zero fiber?that's right, none!
Eat Healthy Fats and Oils
Fats and oils have gotten a bad rap. Somehow the idea has been promoted that all fats are bad and we should eat as little fat as possible. The truth is that fat is an essential part of our diet, and dietary fats are used for many important functions in the body, from energy production to cell membrane maintenance to nerve conduction. While much of the focus has been on the amount of fat we should eat, the type of fats we eat is at least as important.
High-quality fats are rare in the standard American diet. Most of the fats and oils we eat have been damaged by exposure to heat or light during processing or cooking. This damage destroys essential nutrients and creates free radicals, chemically unstable molecules that can wreak havoc in the body. For this reason, fried foods and highly processed fats like margarine and shortening are best avoided. Health concerns have been raised about margarine, as it contains trans fatty acids?a configuration of fatty acids not found in nature.
And our ratio of fat consumption is skewed. Most Americans consume too many saturated fats and not enough polyunsaturated oils. How do you tell which fats are saturated and which are not? Saturated fats are solid at room temperature (think butter, lard and coconut oil). Polyunsaturated oils are liquid at room temperature (like corn oil, safflower oil and sunflower oil). In addition to polyunsaturated oils, olive oil, a monounsaturated oil, is also a heart-healthy choice and one of the best oils to use.
Reduce Your Consumption of Animal Products
While animal products (meat, poultry, fish, eggs and dairy products) contain many valuable nutrients, as a nation, we tend to overdo it. A diet high in animal products is a diet high in cholesterol, and is strongly linked to the number-one killer in the industrialized nations: cardiovascular disease, which includes high blood pressure, heart attacks and strokes.
How do you know which foods contain a lot of cholesterol without having to read labels? All animal products contain cholesterol. All plant foods (grains, legumes, fruits, vegetables and nuts and seeds) contain zero cholesterol. It's that simple. Eating a predominantly vegetarian diet is one way to maintain your cardiovascular health.
Avoid Stimulants?Like Caffeine
Most people think caffeine "gives" them energy. Nothing could be farther from the truth! Caffeine in fact robs the body of energy?by withdrawing from your energy 'savings account' now, leaving you less reserves to draw upon later. The pick-me-up feeling artificial stimulants provide is inevitably followed by an energy crash.
Reduce Your Caloric Intake
About a quarter of the U.S. population is now considered to be obese, and the numbers are rising. Our children are increasingly overweight, from a steady diet of junk food and TV-watching. As a nation, we are overfed and undernourished?our diets are too high in "empty" calories and too low in essential nutrients.
Being overweight significantly increases the risk for a variety of cancers, including colon, prostate, breast, ovarian, and uterine cancer. Animal studies have shown that the only consistent way to extend the life spans of laboratory animals is to put them on a lower calorie diet. Thinner rats live longer?and we suspect the same is true for humans.
Are you too serious about your diet? Do you miss out on social opportunities because you are too busy counting calories or grams of fat? Lighten up! To paraphrase one poet, "?Tis better to eat steak and beer with cheer than sprouts and bread with dread!" Don't allow your dietary restrictions to rule you or limit your social life.
Eating out is possible, even on a restricted diet. Most restaurants are willing to accommodate your requests. It's just a matter of learning how to order the healthiest meal possible. Good options include poached fish with lemon, salads with vinaigrette dressing, and plain baked potatoes. Get in the habit of ordering sauces on the side and avoid filling up on empty calories, like white bread rolls.
Take Time To Savor Each Meal
We often make the mistake of eating hurriedly, standing at the sink wolfing something?anything!?down so we can move on to the next activity in our busy lives. But digestion actually functions better when we take the time to slow down. The parasympathetic nervous system is responsible for enhancing circulation to the digestive organs and promoting the flow of digestive juices. There is only one catch?we must be relaxed for our parasympathetic nervous system to predominate. So, take a deep breath and relax, there's plenty of time!
