Everybody Should Switch Back To Butter, It Is the healthier Choice
Years ago, there was a push to switch to vegetable oil. Unfortunately, most everybody didn't realize that vegetable oil is not a healthy choice. Vegetable oil is mostly made up of Omega-6, American diets have 30 to 100:1 Omega-6 : omega-3 ratio. Omega-6 is bad for the body when it is the dominant oil in our diets. Omega-6 causes inflammation in the body. Most Americans have chronic inflammation, consuming vegetable oil does not help matters at all. Everybody should switch back to Butter.
Have you had your butter today?
Sources of Essential Fatty Acids

Sources of Essential Fatty Acids
Essential fatty acids are found in both plant and animal sources, although primarily in plants. The EFA family is composed of two main forms, Omega-3 and Omega-6. The following explains exactly what these forms are.
OMEGA-3: The most common forms of Omega-3 are eicosapentaenioic acid (EPA), docosahexaenoic acid (DHA) and alpha-linolenic acid, which comes from plants and helps create EPA and DHA. Omega-3 is usually derived from fish oils. Dr. Roger Illingworth, associate professor of medicine and biochemistry at Oregon Health Sciences University, explains that Omega-3 fatty acids are “long-chained metabolic products from linolenic acid. . . When animals consume and metabolize plants rich in linolenic acid, they produce Omega-3.” EPA and DHA are liquid and remain that way, even at room temperature. It is said that they protect fish by providing a body fat that stays fluid even in cold temperatures. Omega-6: The most common form of Omega-6 is is gammalinolenic acid (GLA). GLA is known to provide the following benefits, among many others:
Omega-6 is usually found in plant sources. The oils of coldwater fish such as salmon, bluefish, herring, tuna, mackerel and similar fish are known as Omega-3 fatty acids. The freshpressed oils of many raw seeds and nuts contain Omega-6 fatty acids. The most popular sources of Omega-3 and Omega-6 include:
BLACK CURRANT SEED OIL: This oil is rich in linoleic acid (44%) and provides almost twice as much gamma-linolenic acid as evening primrose oil. Black currant seed oil also is an excellent source of an Omega-3 precursor known as stearidonic acid. BORAGE OIL: This oil comes from Borago officinalis, a plant with blue flowers. It is widely recommended in Europe to strengthen the adrenal glands, alleviate symptoms of premenstrual syndrome and relieve inflammation. Besides possibly helping with heart and joint function, it may also assist the growth of nails and hair. Borage oil is also an excellent source of GLA. In The Complete Medicinal Herbal, herbalist Penelope Ody asserts that it is “helpful in some cases of menstrual irregularity, for irritable bowel syndrome, or as emergency first aid for hangovers.” SALMON OIL: This oil is high in Omega-3 essential fatty acids. These types of EFAs are known to thin the blood, prevent clotting, regulate cholesterol production and strengthen cell walls, making them less susceptible to viral and bacterial invasion. Salmon oil has a natural ability to help the body relieve inflammation. In the ground-breaking book The Omega-3 Breakthrough: The Revolutionary, Medically Proven Fish Oil Diet, professor Roger Illingworth writes that Linolenic acid is a fatty acid with 18 carbons and 3 double bonds.
It is manufactured exclusively by plants. When animals consume and metabolize plants rich in linolenic acid, they produce Omega- 3. Plankton, a minute form of marine life, is part plant and part animal. Its plant component manufactures linolenic acid. Fish eat the plankton, and the linolenic acid breaks down in their bodies in two types of Omega-3 fatty acids: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) . . . The liquidity of EPA and DHA serves a vital function in fish, who require body fat that remains fluid even in very cold water. Fish oils, besides containing Omega-3 fatty acids, have shown to benefit those suffering from migraine headaches, arthritis, and high cholesterol levels.
FLAX: Flax is a plant said to date back as far as 5000 B.C. It has been used since approximately 5000 B.C., making it one of the oldest cultivated crops. It is exported from several countries, including Argentina, Canada, India, Russia and the United States. The flowers are usually blue, although they are sometimes white or pink. The mucilaginous seed is, of course, called flaxseed. The oil primarily provides Omega-3/linolenic acid, and provides an average of 57 percent Omega-3, 16 percent Omega-6, and 18 percent of the non-essential Omega-9. Flaxseed oil is said to contain rich amounts of beta carotene (about 4,300 IU per tablespoon) and vitamin E (about 15 IU per tablespoon). In the October 1995 issue of Let’s Live, the history and uses of flax were highlighted by herbalist Carla Cassata. She writes, . . . It’s no wonder the Cherokee Indians highly valued the flax plant. They mixed flaxseed oil with either goat or moose milk, honey and cooked pumpkin to nourish pregnant and nursing mothers, providing them with the needed nutrients for creating strong and healthy children. It was also given to people who had skin diseases, arthritis, malnutrition as well as men wishing to increase virility. They believed flax captured energies from the sun that could then be released and used in the body’s metabolic process.
This belief has merit. Flaxseed oil, rich in electrons, strongly attracts photons from sunlight. To be effective, EFAs must be combined with protein at the same meal. This flaxseed oil/protein/ sunlight combination releases energy and enhances the body’s electrical system. Also, this combination, along with vitamin E, can be beneficial for infertile couples and women suffering from premenstrual syndrome . . . Flaxseed oil, having an anti-inflammatory effect on the body, can benefit the 40 million Americans suffering from osteoarthritis and rheumatoid arthritis. To achieve optimum results, however, substances that activate the sympathetic nervous system—like refined sugar, soda, coffee, fluoride— must be eliminated. Stress must also be reduced, because it too, activates the sympathetic nervous system, promoting inflammation.
EVENING PRIMROSE: This flower is indigenous to North America, although the oil is particularly popular throughout Europe for therapeutic purposes. It is also known as night wil - low and evening star. It is an excellent source of both linolenic and linoleic acids. Both of these nutrients must be obtained from the diet, as the body cannot synthesize them. The seeds contain gamma linolenic acid. This polyunsaturated EFA helps with the production of energy and is a structural component of the brain, bone marrow, muscles and cell membranes. Evening primrose oil has also benefited those with multiple sclerosis, PMS, hyperactivity and obesity. It is estimated that it takes about 5,000 seeds to produce the oil for one 500 mg capsule.
Cancer at the Millenium - the war on cancer entering its third decade...

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.
