Does Fish Oil Habit Boost Cancer Risks?

New headlines about omega 3s and cancer risks are creating buzz. No surprise given the startling conclusions that fish oil raises the risks of prostate cancer by a frightening 44 percent among men with the highest levels of these fats in their blood. Even more alarming, the study found that compared to those with the lowest levels of these fats, men with the highest amounts are at a whooping 71 % greater risk of the disease. However, the study while important in advancing our knowledge of omega s3 and their imppsct on the development of cancer was not designed to determine cause. It means it is unclear if fish oil is at play or there is something else about fish-oil eating men that raises their risk. May be men that men who have high levels of fish fats in their blood also favour another food or supplement that is the real culprit. May be these guys took supplements to make up for a cummy diet. And since the study did not consider participant's eating habits, researchers can not put the blame on fish or pills, though they caution against the supplements since they are such a concentrated source of the nutrients. Most health authorities suggest eating two servings of seafood each week, an amount that protects against heart diseses, the leading cause of death among men and women. It is reassuring in the recent study that difference in blood levels between the lowest and highest figures exceeds the amount you would get from eating salmon twice a week ( a notable source of the nutrient).
