No protection from fish
Eating fish is often promoted as beneficial to heart health. New research from the Rotterdam Study looking at fish intake and the incidence of heart failure found that fish did not offer such protection. Researchers followed the diets of over 5,000 adults for 11 years during which time almost 670 had heart attacks. Results showed that eating fish made no difference to the risk of heart failure.
