Fish Oil Fails to Prevent Cancer

Fish OilFish oil recommendations are insignificant in preventing cancer, cardiovascular disease and other diseases. Fish oil supplementation also may be dangerous to your health. In June 4-9, 2000, The International Society for the Study of Fatty Acids and Lipids (ISSFAL) 4th Congress, which was held in Tsukuba, Japan, reported the following: “Studies indicate that at the levels used, fish oil [comprised of omega-3 derivatives] decrease a wide range of immune cell responses (natural killer cell, cytotoxic T lymphocyte activities, lymphocyte proliferation and production of IL-2 and IFN-y (1,2))…”, “…Recent studies have indicated that relatively low levels of the long chain omega-3 fatty acids (EPA or DHA)…are sufficient to bring about some of the suppressive effects…”, “…This decrease (of inhibited lymphocyte proliferation and natural killer cell activity) causes increased cellular bacteria [infection] and impaired tumor cell killing.”

Any substance causing impaired tumor cell killing ability can cause cancer which is the opposite of what most people desire. With so many people consuming fish oil, could this be another reason that cancer contraction rates are increasing instead of decreasing? Fish oil is worthless in preventing heart disease, too, and Harvard Medical School warned people years ago, but too few Americans listened. Consuming whole fish instead of fish oil failed, too. That’s why the Japanese have greater cancer rates and greater heart disease rates than Americans.

Since 1981, cancer has been Japan’s #1 cause of death. The popular press doesn’t often disclose these startling facts. People are misled again. In 2006 the omega-3 anticancer fallacy was exposed: “A large body of literature spanning numerous cohorts from many countries and with different demographic characteristics does not provide evidence to suggest a significant association between omega-3 fatty acids and cancer incidence.
