Fish consumption has been linked to a reduced risk of heart disease and death from heart attacks. There are also data suggesting that fish can help protect the brain from strokes. And fish eaters appear to be less vulnerable to macular degeneration, one of the leading causes of blindness in the world today.
Now a study of more than 20,000 subjects over 10 years suggests that the greater the fish intake, the lower the risk of developing type 2 diabetes. White fish and oily fish were the most beneficial. Fried fish did not seem to be helpful, and shellfish actually was associated with an increased risk of diabetes. The shellfish finding was a bit of a mystery and prompted the investigators to suggest additional research to determine if it was real and if the cooking method or some other factor might be responsible. The bottom line, though is that fish is good for the heart, the brain and the metabolism.
