Fish Oil

Scientists report they have evidence that might explain why fish oil would be effective for treating diseases in which the immune system malfunctions, like rheumatoid arthritis. A fatty acid found in fish oil appears to suppress key immune system hormones, perhaps preventing the immune system from attacking the joints and other parts of the body in autoimmune diseases, the researchers found. "We think we have the mechanism as to why this may work," said Dr.

Oil from cold water fish, shown by several studies to help prevent heart attacks, may work its magic by retarding a growth protein that promotes clogged arteries, a Cleveland researcher says. Paul L. Fox of the Cleveland Clinic Research Institute said that test-tube experiments showed that oil extracted from the flesh of fish that live in cold water decreases levels of a protein called the platelet-derived growth factor.

People who eat fish rich in heart-healthy omega-3 fatty acids, such as salmon and tuna, appear to have less hostility than those who don't eat such fish. Dr. Carlos Ibarren, a researcher with Kaiser Permanente in Oakland, and colleagues at several medical centers analyzed eating habits and psychological tests of 3,581 urban adults, ages 18 to 30, who participated in a federal heart study.

Fish oil, long touted as an aid to reducing cholesterol, may prove effective in treating manic depression, according to a preliminary study of 44 patients at Harvard University. The results from that study were so positive that the study was ended prematurely, and all of the patients were given the food supplement. Fish oil is especially high in omega-3 fatty acids, which have been associated with other health benefits.

Fish oil supplements started gaining popularity a couple of decades ago when evidence began to emerge that diets rich in cold-water fish, like that of the Greenland Inuit, dramatically reduced the risk of heart disease. Fish oil, particularly when collected from fatty, cold-water fish (such as salmon), is an excellent, concentrated source of omega-3 fatty acids. Among the polyunsaturated omega-3s the oil contains are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).

American women who took fish oil capsules for just three months experienced changes in breast tissue that some researchers think may lower their risk of breast cancer, UCLA researchers say. Asian women have about one-third as much breast cancer as American women. Their breasts also contain a higher amount of a fatty acid called omega-3, which is found primarily in fish. Some researchers think this increased level of omega-3 may exert a protective effect in the breasts.

Federal researchers are in the final stages of selecting participants for a unique study designed to explore the relationship between diets naturally high in fish oils and blood clotting. Awaiting those chosen for the project are 100 days in virtual confinement at the U.S. Department of Agriculture's Western Human Nutrition Research Center on San Francisco's Presidio. For much of that time, 40 consecutive days, the subjects will be fed salmon at both lunch and dinner.
The Food and Drug Administration has decided to halt the marketing of fish oil pills, concluding that they offer no known medical benefits. "At the present time, there is inadequate scientific evidence to support health claims on fish oils or to support claims that these ingredients have an effect on the risk of coronary heart disease," the agency told manufacturers. The agency added that the safety of the product when taken over a long period has not been proven.

Fish oil, which has shown promise of preventing heart attacks, now appears to be the first effective way to keep heart disease patients' blood vessels open after doctors unclog them. A study involving 82 men who underwent coronary angioplasty--in which a balloon is inflated to open up the vessel--found that those who took fish oil extract before, during and after the procedure were less than half as likely to have the vessels close again, a problem known as restenosis.
