One of the biggest problems we have in Western culture is that we have too few omega-3 fatty acids in our diet. The benefits of eating fish, including lower heart disease risk, far outweigh any theoretical cancer risk from contaminants.
A study in the July 2008 Journal of the American College of Cardiology found that the Japanese, who on average eat 100 grams of fish per day, have half as many heart attacks as North Americans. And omega-3-rich plants aren’t the answer. Sources such as flaxseed oil just aren’t as effective as fatty fish in the prevention and management of cardiovascular disease. Two meals of fatty fish a week meet the suggested daily quota of omega-3s that we should be getting.
A diet rich in fish might also help prevent Alzheimer’s disease and kidney cancer, and is essential for fetal brain development . Fish is also a great source of protein, low in saturated fat, and high in vitamins and minerals.
