In a study out this month, researchers found that consuming fish does not reduce the risk of heart failure. After 11 years of follow-up of 5,000 men and women, almost 670 developed heart failure. Those who consumed the most fish had no protective effect, compared with others. This research was part of the Rotterdam Study in the Netherlands where, like all Western nations, heart failure is common.
