Breast Cancer and Fish

The July edition of the British Medical Journal has a large meta-analysis looking at fish, fish oil consumption and the risk of breast cancer. All in all the examined data covering 20,905 cases of breast cancer and 883,585 participants. Their conclusion was that a higher consumption of omega-3 fatty acids (found in fish and fish oil) was associated with a lower risk of breast cancer. They found this to be true in both studies that looked at dietary consumption and in studies that looked at omega-3 blood levels. Because so much fish is contaminated, it is a good idea to limit one's fish intake to twice a week and then supplement with a high quality fish oil that mimics the natural form of fish oil (not the prescription fish oil).
