Flax Shown to Be Effective Against Cancers of the Colon and Breast

Flax oil and flax seeds have been shown to lower blood cholesterol and triglycerides, and to help reduce damage to cell membranes. Flax is also important in the body’s ability to reduce inflammation and prevent the many degenerative diseases associated with it. Studies have shown that women with a high intake of flax oil and flax lignans are at much lower risk of developing breast cancer. Research is now documenting the benefits of flax oil, lignans, and flax meal in preventing and treating cancer in the gastrointestinal tract and colon, and breast cancer metastasis.Recent studies and results
In a study published in the journal Food and Chemical Toxicology researchers noted that flax seed oil and flax seed meal are good sources of omega-3 fatty acids. Their objective was to investigate the feeding of flax seed oil and flax meal to groups of rats with induced precursors of colon cancer. These precursors form in the lining of the colon and rectum prior to the appearance of colorectal polyps.
The groups of rats were fed either a controlled diet alone, controlled diet plus soybean oil, controlled diet plus flax oil, or controlled diet plus flax meal. The rats were examined after 17 weeks. Those fed the flax seed oil and the flax seed meal showed reduced incidence of colon cancer precursor by 84% and 87.5% respectively. Glutathione-S-transferase (GST) activity rates were significantly higher in the rats fed flax seed oil and flax seed meal compared to those fed soybean oil. The enzymes in GST play a significant role in the detoxification of such substances as carcinogens, therapeutic drugs, and products of oxidative stress.
In the Journal of Nutrition and Cancer researchers note that fatty acid composition of dietary fat plays a vital role in colon tumor development in animal models. Fats containing omega-3 fatty acids, such as flax oil, and those containing omega-6 fats, such as corn oil, reduced chemically induced colon tumor development in rats. Lignans have also been shown to prevent colon tumor development in animal studies. These researchers investigated the effects of dietary flaxseed meal, a source of both omega-3 fatty acids and lignans, on colon tumor development and compared them with the effects of dietary corn meal.
