Date:
November 06, 2015 11:14 PM
The human body is a miracle designed differently. At conception, our cells are encoded with a genetic blueprint and if kept clean with all nutrients provided, the cells will perform perfectly. Current research shows that our bodies are engineered for up to 120 years but our lifespan nowadays wind up to 60's to 70's only. This is a result of poor maintenance of the body. When one starts to get older, the more damage accumulates in the cells and speeds the aging process. But we can never escape aging. Aging is controlled by two factors which are heredity and the internal and external elements that results to our way of living. These external and internal factors can be the kind of food we eat, quality of air we breathe and also the amount of stress that accumulate in our bodies. Consumption of excess alcohol, smoking, oxidized fats and chemicals in food speeds the aging process. Oil is one of the causes of absorption issues in the colon. Example, cooking meat creates a substance called hetero cyclic amines which cause colon cancer. Poor elimination and toxic buildup are said to be a result of premature aging. Poor digestion and absorption drives the aging bodies to nutrients they need. The solution to slow down aging is to eat food that are nutrients-dense and low-calories. The absorption of food by the colon is determined with what we eat. The best diet for the colon is a natural diet which is easily digested by our bodies. The more you take man-made ingredients, the more you make it difficult for food to digest. This means when the food will be passed to the colon from the small intestine what will remain to the colon will not be digested hence making it difficult for the colon.
Diatomaceous Earth suggests that the best diet for a healthy colon in the absorption of food is fiber and water. Fiber means adding more plant based food on the diet. These include eating more vegetables, whole grains, fruits and nuts. Fiber helps retain water and roughage in the body making your stool softer for easy passage to the colon. Another way is that you can conduct a colon cleanse. This removes old fecal matter and helps the colon to function more. Diatomaceous Earth is good for lowering blood pressure, cholesterol, and good for the skin hair and bones. When taking diatomaceous earth make sure you take a lot of water because it dries you off. Drinking water not only provides moisture to your body but also helps to remove out toxins. Avoid drinking drinks with sugar especially those that got high fructose corn syrup. The colon is the most important part of the waste treatment. The more we take care of our bodies the more energy we will have. To restore our health we need good diet and a good colon that will help our bodies function.

And that’s why we’re so excited to introduce new Erythritol. Since the early 1990’s, the popularity of this low-calorie, white crystalline sugar alcohol has steadily increased, and is now becoming the norm among many consumers and businesses alike. With a sweetness that is approximately 70% that of sucrose, a non-hygroscopic texture to prevent clumping and easy digestibility, it’s easy to see why so many are turning to this completely safe polyol.*Low Calorie One of Erythritol’s most unique characteristics is its incredibly low caloric content. While polyols are generally known for being low calorie by nature, Erythritol exemplifies this characteristic, and contains just 0.2 calories per gram. Safe for Teeth Erythritol is non-cariogenic, and does not metabolize the oral bacteria that break down sugars and starches needed to produce the acids that lead to cavities and decay. In fact, the FDA recently released a qualified health claim stating that polyols including Erythritol “do not promote tooth decay”.* Won’t Raise Blood Sugar Several studies have suggested that Erythritol won’t raise blood sugar or insulin levels, and may therefore be a safe alternative to sucrose-based foods designed especially for diabetics.* Easily Digested Based on the small size and unique molecular structure of Erythritol, it is easily absorbed by the small intestine. As a result, gas and laxation are far less likely in comparison to sucrose.* Zero Impact Carbs
As one of only two polyols that carry a glycemic index of zero, Erythritol has zero “impact carbohydrates”.*

From corssets to stomach stapling and liposuction to wiring our jaws shut, we’ve tried it all. So where are we today? The following are indicators of abundant obesity: Research and public education efforts are in agreement that excessive dietary fat is the primary cause of adult obesity.2, 46, 47 Despite the fact that food manufacturers have flooded the supermarkets with low-fat, artificially sweetened, “lite” products, we are fatter than ever before. Is maintaining a healthy weight really that difficult? In its simplest form gaining or losing weight is a matter of the balance between energy in and energy out. This simplistic approach led to the early starvation diets. Unquestionably, these conventional very-low-calorie diet plans do not work. For most of us the first thing we lose is our sense of humor; then maybe some weight or possibly our self-esteem. The fact is, as most of us have regrettably discovered, that drastically reducing our calorie tally only serves to slow our metabolism and make us even more efficient at the business of storing and hoarding fat. Since very-low-calorie diets didn’t work alone, exercise was added to the regime. This also failed miserably because the first thing the body does when it is in a starvation mode is to burn off muscle mass so as to conserve energy supplies. In fact, in animal studies, semi-starved animals maintained nearly the same fat to muscle ratio as their well-fed litter mates.43,44 Even worse, when food is again available the body not only gains back all the original fat but an additonal few pounds just in case this ever happens again. Is it any wonder then that yoyo dieting leads to obesity and a host of other problems?42,45 The reconstruction of muscle mass after starvation, a much slower process than regaining body fat, leaves a person feeling weak and even more lethargic than before he started his diet.

Date:
June 14, 2005 05:23 PM
America's Most Wanted by Brian Amherst Energy Times, January 6, 2000 The United States eats well, a little too well, according to experts. Amply supplied with a large supply of high-calorie food, our diets might seem to be chock full of every conceivable nutrient. Well, to the question "Getting all the right vitamins, minerals and other nutrients?" the most appropriate answer seems to be "Not exactly." Eating a lot doesn't equal eating a lot of the most important vitamins and minerals. So, which vitamins and minerals are likely to show up in short supply in the typical American diet? Calcium certainly sits at the top of list. According to the most recent Continuing Survey of Food Intake by Individuals, which is conducted by the United States Department of Agriculture (USDA), women and girls age 12 and up are not consuming adequate calcium from their diet. Research reveals that about 1200 mg. day suffices for those over age 50 and 1000 mg a day should be adequate if you're between the ages of 19 and 50. Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Stanford University, ". . .osteoporosis is a pediatric disease." For long-range protection against that bone-weakening disease, kids should eat calcium-rich, low-fat dairy products and plenty of leafy greens (broccoli, cabbage, kale) as well as salmon (with bones), seafood and soy. But the calcium campaign does not end in early adulthood. Bone mass begins to deteriorate at about age 30. Menopausal hormonal changes can exacerbate bone brittleness. Medical conditions, including cancer, liver disease and intestinal disorders; prescription drugs; tobacco and alcohol indulgence; or a decline in activity, especially the weight-bearing kind, also jeopardize bone strength. According to the National Osteoporosis Foundation, about one in every two American women will break a bone after age 50 due to osteoporosis. That translates into about half a million fractured vertebrae and more than 300,000 shattered hips. Frequently, those breaks are life-threatening. Crucial Calcium The critical role of calcium in many body functions is perhaps the most extensively clinically documented among nutrients. Researchers in the Department of Medicine, Oregon Health Sciences University in Portland, reviewed epidemiological and clinical studies conducted over the past two years on the relationship between dietary calcium and blood pressure (J Am Coll Nutr October 1999: 398S-405S). "Nearly 20 years of investigation in this area has culminated in remarkable and compelling agreement in the data," the researchers report, "confirming the need for and benefit of regular consumption of the recommended daily levels of dietary calcium." Investigators at the State University of New York, Buffalo School of Dental Medicine, presented results of their studies of calcium and vitamin C and gum disease at the June 26, 1998 meeting of the International Association for Dental Research. Two separate inquiries revealed that people who consumed too little calcium as young adults, and those with low levels of vitamin C in their diets, appear to have nearly twice the risk of developing periodontal disease later in life than folks with higher dietary levels of either nutrient. Calcium: Much Documented Researchers offer extensive evidence of calcium's benefits on many fronts: n Osteoporosis poses a threat to older men as well as women, according to Randi L. Wolf, PhD, research associate at the University of Pittsburgh Graduate School of Public Health. Dr. Wolf presented her award-winning study to an October 3, 1999 meeting of the American Society for Bone and Mineral Research. Dr. Wolf suggests that men increase their consumption of calcium, particularly after age 80, to avoid age-related declines in the amount of calcium absorbed. According to Dr. Wolf, "It appears that the hormonal form of vitamin D, which is the main regulator of intestinal calcium absorption, may have an important role. We are conducting more research to better understand the reasons for why calcium absorption declines with age in men." n Scientists at Tufts University in Boston did some earlier work on the calcium-vitamin D connection and reported it in the September 4, 1997 New England Journal of Medicine. Using the National Academy of Sciences (NAS) increased recommended daily intake of 1200 milligrams of calcium and 400 to 600 international units of vitamin D for people over 50, the Tufts researchers found that with supplementation of the nutrients, men and women 65 and older lost significantly less body bone and, in some cases, gained bone mineral density. n Two studies published in American Heart Association journals show that atherosclerosis and osteoporosis may be linked by a common problem in the way the body uses calcium. The September 1997 Stroke revealed that, in a group of 30 postmenopausal women 67 to 85 years old, bone mineral density declined as atherosclerotic plaque increased. Researchers reporting in Circulation (September 15, 1997) advanced the theory that the osteoporosis-atherosclerosis connection may be related to a problem in handling calcium. n For people who had colon polyps removed, taking calcium supplements decreased the number of new polyps by 24% and cut the risk of recurrence by 19%, according to researchers at the University of North Carolina, Chapel Hill, School of Medicine. The study, published in the January 14, 1999 New England Journal of Medicine, was a first in crediting calcium with anti-cancer properties. The D Factor Without adequate vitamin D, your absorption of calcium slips and bone loss can accelerate, increasing the risk for fractures. Fifty percent of women with osteoporosis hospitalized for hip fractures at Brigham and Women's Hospital in Boston had a previously undetected vitamin D deficiency (Journal of the American Medical Association, April 28, 1999). University of Pittsburgh Cancer Institute researchers told participants at the April 14, 1997 meeting of the American Association for Cancer Research that vitamin D "significantly inhibits highly metastatic, or widespread, prostate cancer in animals," suggesting its potential for treating men with similar conditions. Few foods that Americans eat, except dairy, contain much vitamin D, but we can usually synthesize sufficient amounts from as few as five minutes' exposure to the sun. But as skin ages, its ability to act as a vitamin D factory decreases. According to Michael F. Holick, the director of the Vitamin D, Skin and Bone Research Laboratory at Boston University Medical Center, upwards of 40% of the adult population over age 50 that he sees in his clinic are deficient in vitamin D. Recently, the National Academy of Sciences (the official body that decrees the required amounts of necessary nutrients) increased the daily recommendations of vitamin D to 600 IU for people over 71, 400 IU for those aged 51 to 70 and 200 IU for people under 50. The best dietary sources, apart from dependable supplements, are dairy and fatty fish like salmon. Four ounces of salmon provide about 300 IU. The Facts About Fats The American lust for low-fat, high-carbohydrate diets filled with sugary foods has exploded into nothing short of "obsession," according to experts at the General Research Center at Stanford University Medical Center (Am J Clin Nutr 70, 1999: 512S-5S). That mania oftens robs us of the crucial balance of omega-3 and omega-6 fatty acids typical of the Mediterranean diet that protect us from heart disease by controlling cholesterol and making blood less likely to form clots. These fatty acids cannot be made by the body but are critical for health: n Omega-3 fatty acid (linolenic acid) comes from fresh, deepwater fish (salmon, mackerel, sardines) and vegetable oils such as canola, flaxseed and walnut. n Omega-6 fatty acid (linoleic acid) found primarily in raw nuts, seeds and legumes and in saturated vegetable oils such as borage, grape seed, primrose, sesame and soybean. The American Heart Association recommends limiting total fat consumption to 30% of daily calories. Saturated fats like those in dairy and meat products as well as vegetable oil should comprise 10% of total calories; total unsaturated fat (fish oils, soybean, safflower nuts and nut oils) should be restricted to 20 to 22% of daily calories. Be Sure About B12 Vitamin B12 presents a particular problem for the elderly because older digestive systems often don't secrete enough stomach acid to liberate this nutrient from food. (The elderly have no problem absorbing B12 from supplements, because it's not bound to food.) Vitamins generally moderate the aging process but, ironically, that process and the diseases that frequently accompany it affect vitamin metabolism (Schweiz Rundsch Med Prax 83, 1994: 262-6). And because of those changes, we need more of certain vitamins. This is the case for vitamins D, B6, riboflavin and B12. Crucial for health, B12 is necessary to prevent anemia, and, according to recent studies, needed (along with folate and B6) to help stave off heart disease. B12, with thiamine and niacin, boosts cognition (Adv Nutr Res 7, 1985: 71-100). Screening for vitamin B12 deficiency and thyroid disease is cheap and easy and can prevent conditions such as dementia, depression or irreversible tissue damage (Lakartidningen 94, 1997: 4329-32). In the January 5-12, 1999 issue of Circulation: Journal of the American Heart Association, the AHA urged doctors to screen levels of homocysteine (the amino acid byproduct of protein digestion that damages arteries, causes heart disease and, possibly, strokes) in patients at high risk for heart disease. They also recommended all Americans to up their daily levels of vitamins B6 and B12, as well as folic acid. Since fruits, vegetables or grains lack B12, vegetarians need B12 supplements. And they're a good idea for the rest of us, too. Folic Acid Benefits Folic acid made headlines in the early 1990s when the U.S. Public Health Service declared that "to reduce the frequency of neural tube defects [spina bifida, or open spine, and anencephaly, a lethal defect of the brain and skull] and their resulting disability, all women of childbearing age in the United States who are capable of becoming pregnant should consume .4 milligrams (400 micrograms) of folic acid per day." This recommendation followed voluminous research that showed taking folic acid was associated with a significantly reduced risk of birth defects. (The advisory is based on the fact that nearly half of all pregnancies are unplanned. If you think you are pregnant, consult your health practitioner for supplementary advice.) A Team Player Folic acid's efficacy intensifies when it works with other nutrients. Among many studies on the preventive powers of folic acid on birth defects, one published in The New England Journal of Medicine (327, Dec. 24, 1992: 1,832-1,835), disclosed an even greater decrease in neural tube defects when supplements of folic acid contained copper, manganese, zinc and vitamin C. As a warrior against homocysteine, folic acid joins the battalion of B12 and B6 in detoxifying this harmful protein. At the University of Washington's Northwest Prevention Effectiveness Center, researchers recently analyzed 38 published studies of the relationship between folic acid, homocysteine and cardiovascular disease and, according to associate professor Shirley A. Beresford, MD, folic acid and vitamin B12 and B6 deficiencies can lead to a buildup of homocysteine. Compelling Evidence Canadian researchers reported in the Journal of the American Medical Association (275, 1996: 1893-1896) that men and women with low folic acid have a 69% increase in the risk of fatal coronary heart disease. This 15-year study of more than 5,000 people stressed the need for dietary supplementation of folic acid. Folic acid also has been credited with the potential to protect against cancers of the lungs, colon and cervix. It appears to help reverse cervical dysplasia, the precursor cells to cervical cancer, especially for women taking oral contraceptives, which may cause a localized deficiency of folic acid in the cells of the cervix. According to Shari Lieberman, PhD, and Nancy Bruning, authors of The Real Vitamin & Mineral Book (Avery), folic acid derivatives work with neurotransmitters, the chemicals that permit signals to be sent from nerve fiber to nerve fiber. A lack of folic acid can cause some nervous-system disorders, such as depression, schizophrenia and dementia; it also may be related to some forms of mental retardation. Other supporting roles of folic acid, according to researchers: the formation of normal red blood cells, important for preventing the type of anemia characterized by oversized red blood cells; strengthening and improving white blood cell action against disease; limiting production of uric acid, the cause of gout. The Best Sources Many foods are rich in folic acid: beef, lamb, pork and chicken liver, spinach, kale and beet greens, asparagus, broccoli, whole wheat and brewer's yeast. But experts believe that only 25 to 50% of the folic acid in food is bioavailable. Processing also reduces an estimated 50 to 90% of its content. Folic acid supplementation overcomes these obstacles with little risk, as it has no known toxicity. Women taking folic acid who are current or former users of oral contraceptives may require additional zinc. And be sure to augment your folic acid supplement with its synergistic counterpart, vitamin B12. Focus on Fiber The American Heart Association came out squarely behind fiber in a June 16, 1997 issue of its journal Circulation: Double your daily intake to lower cholesterol and the risk of heart disease. The American diet is consistently low in fiber, notes Linda Van Horn, PhD, RD, author of the article. Twenty-five to 30 grams a day from foods (or supplements) are not only heart healthy but seem to aid weight control. Iron Problem Getting enough iron? An estimated 25% of adolescent girls in the United States are iron deficient, according to an October 12, 1996 issue of the British medical journal The Lancet, which reported that girls who took iron supplements performed significantly better on verbal tests than those who took a placebo. "Teenage girls should be regularly tested for iron deficiency because rapid growth and the onset of menstruation during puberty increase the body's need for iron," says Ann Bruner, MD, of the Johns Hopkins Children's Center and a lead author of the study.USDA data reveal that women up to age 50 also tend to get much less than recommended levels of iron, a lack of which leads to anemia, a deficiency of red blood cells, hemoglobin or volume of blood. For kids, deficiency is more common from six months to four years and during the rapid growth spurts of adolescence when the body is growing so quickly that the body's iron stores may sink to dangerous levels. Vegetarian women run the greatest risk for deficiency, as meat is iron-rich; foods like beans, grains and vegetables also contain some iron. Supplements, of course, supply easily absorbable iron. And to absorb iron from vegetarian sources, take vitamin C with your meals. That boosts the amount of this mineral you will take in. Bear in mind, however, that certain folks-older men and post-menopausal women-generally have adequate dietary supplies of iron. Of greater concern, in fact, is excessive iron, and for these folks iron-free multivitamin and mineral supplements are available. Ante Up the Antioxidants Antioxidant nutrients help protect the body from oxygen-scavenging molecules called free radicals. The products of pollution, the body's own metabolic processes and other sources, free radicals are linked to heart disease, cancer and other chronic health problems. The most important antioxidants, which include vitamin C, E, beta carotene, and selenium, are often lacking in the American diet. Plus, optimal amounts of vitamin E cannot be consumed from food. You need supplements. The bottom line: even though we live in a land of plenty, you can still miss vital nutrients. So make sure to consume these vital substances. Sprouts: Nutritional Source of Missing Nutrients In the search for the nutrients missing from America's diet, one big help is the sprout. The sprout is truly one of nature's heavyweights: fresh, tiny and moist, its power punch of vitamins, minerals, protein, chlorophyll and disease-busting phytochemicals land it in a weight class far beyond that of its full-grown competitors. Size does NOT matter to this nutritional giant. A championship belt currently wraps around the miniscule broccoli sprout, catapulted into the ring by Paul Talalay, MD, professor of pharmacology and molecular sciences at Johns Hopkins University. Dr. Talalay discovered that the seedlings contain substantially more of the cancer-fighting substance sulforaphane than mature plants (Proc. Natnl. Acad. Sci. USA, 94, 10367-10372). Sprouts, the quintessential health food of the Sixties, provide a wonderfully varied and versatile way to get your daily greens. Raw or cooked, strong or mild, vegetable and grass sprouts and their algae cousins add low-calorie texture to recipes and a rich, diverse complement of nutrients and fiber. Ancient Asia to the Modern Lab Asians stir-fried sprouts as one of the earliest fast foods as long as 5,000 years ago. The ancient Chinese relied on sprouts for year-round vegetables in colder regions of their vast country. Today, researchers studying sprouts and adult plants have identified their important chemoprotective and other health-bolstering substances. In Paul Talalay's research project at Johns Hopkins, scientists found that three-day-old broccoli sprouts contain up to 50 times more sulforaphane than mature plants, which prompts the body to produce an enzyme that prevents cancer tumors from forming. Uniform levels of the compound saturate the shoots, unlike the chemically uneven adult plants. The Brassica family of broccoli and cabbage is richly endowed with phytochemicals that also help reduce estrogen levels associated with breast cancer. Other phytochemical compounds in the Brassica family are associated with the prevention of stomach and lung cancers. Most of the initial landmark work on phytochemicals' cancer-fighting powers has taken place since 1989 under the aegis of the National Cancer Institute's "Designer Food Program," which isolated, for example, the isoflavones in beans that seem to neutralize cancer-gene enzymes. Strong Suit: Soy and Spirulina The isoflavones and phytosterols in soy produce an estrogenic effect that appears to relieve menopausal symptoms and help prevent breast cancer. Soy foods expert Mark Messina, PhD, has done extensive work on the subject, some of which has been published in the Journal of the National Cancer Institute 83, 1991: 541-6. Researchers also have synthesized a bone-strengthening form of soy isoflavones called ipriflavone, following impressive clinical trials in the treatment of osteoporosis (American Journal of Medicine, 95 [Suppl. 5A] (1993): 69S-74S). Spirulina and other micro-algae are fascinating organisms that inhabit a niche between the plant and animals kingdoms. Named for its tiny spirals, spirulina, a blue-green algae, grows in saline lakes but is cultured for maximum nutritional content. In her book Whole Foods Companion (Chelsea Green), Dianne Onstad notes that spirulina contains "the highest sources of protein, beta carotene and nucleic acids of any animal or plant food." Its nucleic acids, she says, benefit cellular regeneration; its fatty acids, especially GLA and omega-3 acids, make it one of the most complete foods. Sprouts, like any other produce, should be rinsed thoroughly before serving. People at high risk for bacterial illness-young children, the very elderly or folks with weakened immune systems-should limit their consumption of raw sprouts. But no matter how you eat them, you may find more spring in your step from these tiny, sprouting nutritional wonders.

Power Meals by Phyllis D. Light, RH Energy Times, March 12, 2004 Choices, choices, choices: For convenience, nutrition and either low-calorie or low-carb dieting, you now have an enviable range of choices. Shakes, smoothies and bars help make getting good nutrition easy. Whatever your inclination, drinks and bars offer a shortcut to daily nutrition without cooking. And whether you use them as meal replacements, diet aids or healthy snacks, these power meals fill you up without filling you out. That's the main reason these items have grown in popularity in natural food stores among the nutritionally knowledgeable searching for healthier alternatives to fast food. No matter how hectic your day, you have no excuses anymore for missing your daily required antioxidants and minerals. Either select a bar suited to your taste, or put your blender or food processor to work in creating drinks that use fresh fruits and veggies, yogurt, low-fat milk or ice and protein powders for maximum nutritional output. Quality note: always be sure to use organic foods for the best nutritional content, flavor and taste. Powerful Nutrition Prepared protein shake mixes and bars are ideal for losing weight, expanding personal energy or building muscle. Protein mixes are available in an assortment of flavors that are generally high in amino acids (protein building blocks) and low in carbohydrates. Of course if you are on a low-carb diet, forsake putting fruits and vegetables in your shakes; these items are too high in carbohydrates. What's more, bars not only provide a wealth of different tastes, but different bars are also tailored to different needs-whether you're seeking to lose weight, gain muscle or replace a meal, there's a bar out there just for you. If you use power shakes as meal replacements and you are on a low-carbohydrate diet, make sure the drink supplies plenty of protein and few carbohydrates. If you use either shakes or bars to replace one or more meals during the day, take a fiber supplement in addition. Fiber, which contains no calories, helps speed food through your digestive tract and may lower your risk of heart disease and cancer (Lancet 5/2/03). And remember: powders and bars should also be low in sugars and saturated fats. The weight-loss benefit: If you drink high-protein shakes or eat bars that taste good and leave you feeling satisfied, you'll have a better chance of sticking to your diet long enough to lose a significant amount of weight. Drink to Lose Research into weight loss has established protein shakes and bars as reliable diet aids. A study of 100 dieters between the age of 35 and 65 found that people who drank a daily soy protein shake lost more than 14 pounds each in three months (Eur J Clin Nutr 2003; 57:514). And in a study reported in the Journal of American Dietetic Association (3/01), folks who had a protein shake in place of one daily meal lost almost twice as much weight over 12 weeks than those who ate their regular food with the same amount of calories. Drinking your breakfast in the form of a protein shake can both increase your metabolism and help curb your appetite for the rest of the day. Researchers at Harvard University found that metabolism rose faster after eating a high-protein breakfast and that blood-sugar levels stayed high for about six hours after the meal (AHA Annual Conference on Cardiovascular Disease Epidemiology and and Prevention, 3/6/03). In comparison, when a sugary breakfast is consumed, blood-sugar levels rise quickly but fall rapidly, causing fatigue, tiredness and sleepiness. Protein shakes are especially effective when you are on a weight-loss plateau, trying to lose those last few tenacious pounds. (But shakes, smoothies and bars should not be your only meals of the day. Eat at least one low-calorie meal daily to supply nutrients that may not be in your shakes or bars.) Smoothie Operator Made with fruits and vegetables, smoothies are a tasty way of getting extra amounts of nutrients and soluble fiber. Using low-fat milk, yogurt, buttermilk or kefir, plus ice, creates a tempting and wholesome blend that lights up the taste buds. Powdered mixes can be used for added protein. Fruits and vegetables in your smoothies not only fill you up on relatively few calories, but they boost your energy and supply plenty of bioflavonoids (healthy, natural chemicals from plants), antioxidants, vitamins and minerals. The fiber in smoothies can help reduce cholesterol, relieve constipation and aid in the prevention of high blood pressure. For reduced calories and added heart health benefits, low-fat or no-fat milk products can be used in place of cream or regular milk in most recipes. For the best taste sensation, combine sour and sweet fruits together. Adding raw fruits and vegetables to smoothies provides natural enzymes that help with digestion and act as catalysts in hundreds of chemical reactions throughout the body. (You can also take enzymes in supplemental form.) Enzymes are not present in cooked foods since the heat of cooking destroys them. Nutrition for Kids If you have trouble getting your children to eat their fruits and vegetables, try giving them smoothies. Children can't resist these naturally sweet and healthy creations. According to Sally Fallon, author of Nourishing Traditions (New Trends Publishing), smoothies should be "high in quality, contain healthy fats, be naturally sweet, and contain fresh seasonal fruits and vegetables." Fallon also believes children should consume what are called lacto-fermented foods, including yogurt and kefir, which are aged to contain the kinds of friendly bacteria that normally live within our digestive tracts. For kids, Fallon also encourages the use of cream or cultured milk to ensure adequate fat and calcium, so important for the development of growing bodies. Smoothies are an interactive drink as far as children are concerned, since they love to help blend them. For extra nutrition power, add nutritional yeast, nut butters or ground flaxseeds. These supply additional vitamins and minerals, along with healthy fats. You can also add silken tofu to bump up the protein content. If your child is lactose intolerant, try mixing smoothies with rice milk, soy milk or juice. Bars Designed With A Woman's Needs in Mind The modern woman is a multitasking wonder, constantly juggling work and home responsibilities. So it's no wonder that bars aimed at women are among the most popular bars there are. Many women, in eyeing the bathroom scale, shortchange themselves of the nutrients they need. That's why a woman's bar needs to provide minerals like calcium, a bone-building necessity. Women also need to ensure that a bar contains enough of the B vitamins, particularly folate. This is especially true if a woman is pregnant, or wants to be: Folate is crucial in helping to prevent neural tube birth defects. Folate also teams up with two other B vitamins, B6 and B12, to control homocysteine. This protein metabolism byproduct, when present in excessive amounts, is associated with heart disease. Another popular ingredient in women's bars is soy, which has been duly recognized for its heart benefits. Studies also indicate that soy may help keep bones strong. (Not to mention the fact that the moisture soy holds helps make a bar's texture that much more appealing!) The Protein Game If you are unsure about how much protein you need each day, you are not alone. Are you getting too much, not enough, or just enough? Most people need between 45 and 60 grams of protein daily, and most protein shakes contain about 14 and 20 grams of protein per serving (check your labels). No matter what your nutritional needs are, you may find an answer in a smoothie, shake or bar. When it comes to power nutrition, tasting is believing!

Date:
June 12, 2005 08:03 AM
Down with Blood Pressure by Kim Erickson Energy Times, January 6, 2002 More than one of four Americans suffers from high blood pressure, also known as hypertension. This so-called silent killer is often the first step in developing long-term problems like heart disease and stroke. According to the American Heart Association, high blood pressure leads to about 45,000 deaths a year and contributes to another 210,000. Hypertension is more common in women beginning at age 50, particularly African-American women. And since high blood pressure rarely causes obvious physical distress, unless your health practitioner monitors your blood pressure on a regular basis, it's easy to miss. The famous study by the National Heart, Lung and Blood Institute (NHLBI), known as the Framingham Heart Study, found that half of all people who suffered a first heart attack and two-thirds of first-time stroke victims also had moderate to high blood pressure. What's more, left untreated, high blood pressure can also increase the risk of atherosclerosis (hardening of the arteries), aneurysms, loss of vision and kidney failure. Normal blood pressure is considered 120/80. When blood pressure reaches 140/90 or above on a consistent basis, you have high blood pressure. What do the numbers mean? The top number, systolic pressure, represents the peak pressure generated in your arteries when your heart beats. The bottom number, diastolic pressure, indicates the pressure when your heart is at rest between heartbeats. Among 95% of all people with high blood pressure, health practitioners can generally pinpoint no specific, single cause. So Salty For decades, the most common recommendation for people with high blood pressure was to eat less salt. Experts have advocated reducing our salt intake to no more than three teaspoons a day: six grams (2400 mg), which is four grams less than the current national average. This recommendation was largely based on a study conducted by Northwestern University Medical School in Chicago, Illinois, known as INTERSALT. The study tested more than 10,000 men and women from 32 countries. The researchers concluded that eating a lot of salt was linked to rises in blood pressure. Other scientists haven't always found the same results. One review of 56 clinical trials by the Integrative and Behavioral Cardiology Program at the Mount Sinai School of Medicine in New York found only a modest reduction in blood pressure when the salt shaker was left unshaken. And an analysis of 58 studies by academics at the University of Copenhagen, Denmark found that, overall, studies did not support a general recommendation to reduce the amount of salt we consume. Added to all this confusion, many people are salt sensitive: their bodies retain excess salt instead of flushing it out of their systems. Unfortunately, only medical tests can reveal this sensitivity. Consequently, experts still recommend that you eat fewer foods containing salt. That means going easy on processed foods, lunch meats and soft drinks. In addition, increasing your intake of potassium, calcium and magnesium may help your blood pressure. Mitigating Minerals Foods rich in potassium and magnesium not only help regulate blood pressure, but may boost overall cardiovascular health and reduce the risk of stroke. Vegetarian items such as bananas, baked potatoes and oranges are rich in these minerals. Research that looked at 30,000 doctors found that those who ate diets rich in fiber, potassium and magnesium had lower blood pressure than the men who ate few of these mineral-rich foods (Circ, 1992; vol 86:1475-1484). A study of 40,000 female nurses found that their pressure decreased when they consumed fibrous and magnesium-filled foods (Hypertension, 1996, vol 27:1065-1072). CoQ10 The nutrient CoQ10 is a vitamin-like substance which acts as an antioxidant in the body, decreasing the harm caused by caustic substances known as free radicals. Found in every part of the body, CoQ10 is necessary for producing energy in every cell. But it is estimated that nearly 40% of people with high blood pressure are deficient in CoQ10. Tests of CoQ10 seem to show that it can often reduce blood pressure by almost 10% (Cur Ther Res 1990;47: 841-845). It also appears to reduce blood triglycerides, blood fats linked to heart disease, and insulin, while slightly increasing HDL (good) cholesterol. Food Fight Perhaps the biggest breakthrough in lowering blood pressure without the use of prescription medicine came with a study known as DASH (Dietary Approaches to Stop Hypertension). Funded by NHLBI and the National Institutes of Health, the multicenter study examined more than 400 people with high blood pressure. These folks were divided into three groups. One ate the standard high-sodium, high-fat American diet, the second a diet high in fruits and vegetables, and the third a combination diet rich in fruits, vegetables and low-fat dairy products (the DASH diet). While the group eating plenty of fruits and vegetables enjoyed a modest reduction in blood pressure, the study found that combining low-fat dairy with produce lowered both systolic and diastolic blood pressure by 11.4 and 5.5 points, respectively. And the benefits came quickly. Many of the people on the combination diet lowered their blood pressure within two weeks. The results were so impressive that researchers at Brigham and Women's Hospital in Boston, Massachusetts suggested that the DASH diet may offer an alternative to drug therapy for people with hypertension and may even serve to prevent high blood pressure altogether. The DASH diet is low in saturated fat and rich in whole grains, fruits and vegetables. Similar to the diet found in Mediterranean cultures, DASH also includes nuts, seeds and legumes, and is supplemented by non- or low-fat dairy products. Moderate amounts of protein-in the form of fish, poultry and soy-are also eaten. Eating in the DASH may also spur weight loss. Since being overweight can increase your blood pressure, the NHLBI strongly recommends a low-calorie diet such as DASH to take off extra pounds. Exercise and stress relief play critical roles in most pressure-reducing plans. Working out not only helps shed weight, it can also lower your blood pressure. Low to moderate aerobic exercise four days a week may lower blood pressure just as effectively as a higher intensity workout. And learning how to manage stress has helped dropped pressures in people with hypertension (Arch Intern Med 2001; 161:1071-80). Nutrition and lifestyle: two vital relief valves for dropping your high blood pressure and increasing your chances of longer life.

Date:
June 10, 2005 03:01 PM
Basics of the Immune System by Leonid G. Ber, MD Energy Times, September 1, 1998 In a world filled with pathogens and microbes, good health and resistance to disease is no accident. It requires a vigorous and vigilant immune system. The immune system should be viewed as an internal security force that is constantly checking the identity of everything entering and already existing in the body. A cell or substance may be recognized as "non-self" and a potential enemy if it does not have the right molecular make-up. A cell displaying molecules produced according to a different blueprint than the body's own code may be recognized as foreign. To eliminate alien material that may harm the body, the immune system must take swift action. Recognizing entities that originate outside the self forms the key to overall immune system response. This key is carried in the body by cells called macrophages (ma-kro-fajs), a name derived from a Greek term meaning "big eater." Macrophages eat or engulf foreign cells and molecules. When a macrophage encounters something that it distinguishes as being "non-self" or abnormal, it can attack the enemy with a series of assault weapons, including free-radicals (reactive substances) and enzymes, that dissolve and weaken the intruder. In fact, an enzyme produced by macrophages called lysozyme is recognized as one of nature's most powerful anti-infective agents. These chemical defenses, along with engulfment and complete digestion by macrophages, can effectively stymie invasion by disease-causing pathogens. Disease Invasion Harmful invasion can originate in the body's own cells as well as begin from outside sources. While we are constantly exposed to bacteria, viruses, fungal cells and parasites, destructive cancerous growths often start within the body. Every day, thousands of the body's cells mutate into possible cancers. Under most circumstances, the immune system keeps these cells under control. But when the immune "security" system slips up, these harmful growths multiply unrecognized. Getting Specific The initial immune response that recognizes invaders is called a "non-specific defense mechanism" since this immune response is generally the same toward all invaders. This counter-attack entails battling every invader pretty much identically: a macrophage can engage, dissolve, weaken, engulf, digest, eliminate. However, if, despite the initial immune efforts, the problem persists, a macrophage can tag an invader and "introduce" it to the rest of the immune system, thus recruiting more specialized types of immune cells to enter the battle. This tagging function endows macrophages with the name "antigen-presenting cells." (Antigens are substances that can provoke specific responses by the immune system.) Most antigens are proteins. Proteins are relatively large molecules made of smaller units called amino acids. The specific geometric organization of amino acids is what conveys uniqueness to each protein. (Your genetic code forms a blueprint for the production of your own, individual proteins.) Protein molecules produced by one human being can act as an antigen for another human being. That's why organs transplanted from one person to another can be rejected by the immune system. Unless organs are transplanted from one identical twin to another (who share the genetic blueprint for protein creation), doctors must use immune-suppressing drugs to curtail organ rejection. At the same time as these medicines prevent transplant rejection, they also make people more susceptible to infectious diseases and cancer. Specialized Immunity After one set of immune cells chemically tags antigens (invaders) for recognition, other highly specialized parts of the immune system go into action: Cells called T cells or T lymphocytes acknowledge the invaders and can take the further action (second line of defense) that is necessary to render them harmless. T cells get their name from the thymus (an organ located behind the sternum) where they originate. The thymus, most active when we're young, usually shrinks and apparently slows or shuts down its activity about the age of forty. A wide variety of T cells inhabit lymph nodes (soft, usually round, pea- or nut-sized organs) and other body areas. For instance, natural killer cells, as their name implies, are a particularly aggressive type of T cell. Another type of T cell is called T helper (a cell that supports development of immune response). T suppressors halt immune response when infection ends. In order to make all these different cells work in concert, cytokines or messenger molecules are produced that facilitate constant communications between all the parts of the immune system. The B Team Other organs of the immune system include: *bone marrow: a powerful cell producing organ where the majority of immune cells are born; *spleen: an abdominal organ that forms a reservoir for the production of immune cells. Lymph nodes oversee particular segments of the body where they collect and recycle tissue fluids. Like an early warning system, lymph nodes react when an invader is detected in the part of the body that it controls. Yet another step in the so-called immune cascade entails action by lymphocytes, called B cells, which originate in the bone marrow. These cells produce antibodies which are immune proteins (immunglobulins) that attack specific antigens. While traveling in the blood, an antibody can bind to an antigen, curtailing its harmful action. This bound up molecule forms a complex easily recognized by scavenging macrophages which make a quick meal out of the unlucky invader. After enemy cells are removed from the body, knowledge of this victory resides in the immunological memory prolonging your resistance toward specific disease pathogens indefinitely. That's why someone who has recovered from a disease like the measles may be impervious to reinfection. Rules for Optimum Immunity Even though the immune system consists of a complex team of hard-working cells, enhancing your immunity is relatively easy: Maintain a healthy lifestyle. Avoid continuous stress and negative emotions or cope with them through exercise or meditation. Consistent, moderate exercise can boost the immune system. Massage can also help although extreme care must be taken when inflammation or disease is already present. Sleep 7-8 hours a day. Sleep allows the body to recover and rebuild. Protein synthesis, vital for a healthy immune system, increases during the night. Stick to a healthy diet. Your immune system consists of trillions of cells. Consequently, nutrients important for cell health boost the immune system. A balanced low-calorie diet rich in complex carbohydrates, "good" fats (including fish oils, olive oil and flaxseed oil) along with vitamins, minerals and phytonutrient antioxidants from fresh fruits and vegetables can fortify immune cells. Plus, drinking plenty of water helps improve circulation of lymph fluid. These recommendations are not hard to meet once they become a part of your daily routine. However, extra immune security may be necessary during flu season, while traveling long distances (airplanes are notorious sources of pathogens) or when working extensive hours in front of a computer screen. In addition, exposure to x-rays, immunosuppressive chemicals, ultraviolet radiation (the sun) or simply aging may give your immune cells extra burdens. Your "specific" immune system does not respond immediately to the challenge of invasion by an infectious organism. Instead, it may require about 2 weeks for an effective reaction after antigen recognition and alerting T cells. During this period, the macrophages' non-specific defense assumes a crucial role in keeping infection in check. Enhanced activity by macrophages is especially important for recognizing and destroying cancer cells. The most dangerous cancers are those that can mimic normal cells and avoid the immune system's wrath. Few substances can activate macrophage function in the body (aloe vera contains substances that contribute to this process). The most powerful macrophage activator recognized by the scientific community is a sugar-like substance called beta-1,3-D-glucan. Beta-glucan, extracted from the cell walls of common Baker's yeast, when taken in certain small amounts, can prevent infection by making macrophages more active in recognizing and attacking infectious bacteria, fungi and certain viruses. This kind of activation can encourage macrophages to attack previously unrecognized tumor cells. As a result, tumors may be eradicated as the immune system mobilizes and produces what may be known as "spontaneous healing." Hungry Macrophages When a macrophage works overtime fighting disease, its demand for nutrients and energy increases dramatically. Vitamin C, known for its immune supporting function, seems to be especially important for maintaining fully active macrophages. Vitamin C collects in macrophages, often reaching forty times the concentration found in surrounding blood. What are conventionally considered normal amounts of vitamin C in the body may be insufficient to keep macrophages well supplied with this antioxidant. Therefore, extra amounts of vitamin C can keep the immune system in fighting trim. Scientists are only now beginning to uncover the secrets of the highly organized immune system. One thing's certain: The immunity security team depends on proper lifestyle, nutrition and supplements to maintain the critical defenses necessary for good health. Dr. Ber received his doctorate in internal medicine from the Yaroslavle, State Medical Institute in Yaroslavle, Russia.

As the name suggests, beet root powder is made from ground-up beets. It’s a natural source of nitrates, which the body converts into nitric oxide. This gas helps to widen blood vessels and improve blood flow. In turn, this can help lower blood pressure. Beet root powder may also increase blood flow in the brain, leading to better cognitive function. Additionally, beet root powder is a good source of dietary fiber, minerals (including magnesium, potassium, and zinc), and vitamins (especially vitamin C and beta-carotene). All of these nutrients can offer various health benefits. Beet root powder is typically available in capsules or as a loose powder that can mixed into a drink.
