Earlier studies had shown that frequent fish eaters, like the Japanese and Greenland Eskimos, have low rates of heart disease. Indeed, fish oil has been found to lower certain blood fats and reduce blood clotting, both of which could help prevent heart disease. But until now, there haven’t been any hard data showing whether eating fish actually does that. The new study, conducted over six years on 44,895 American men, found that whether they ate fish once a month or six times a week made no difference in their rate of fatal and nonfatal heart disease. No single study, of course, can be conclusive, and fish is still a relatively low-fat alternative to red meat. But while we’re waiting for the final word, let’s order a pizza with everything on it.
