While we’re on the subject of how diet affects the heart, here’s some good news for women: a study of the eating habits of more than 20,000 residents of the city of Malmo, in Sweden, found that women whose diets were high in fiber had almost 25 percent lower risk of cardiovascular disease than women whose diets were low in fiber. The study also found that a high fiber diet lowered the risk of stroke in men, but didn’t affect male cardiovascular disease risk in general. The researchers suggested that the difference between the sexes may have to do with the fact that the women in the study obtained most of their fiber from fruits and vegetables, while the men got most of theirs from bread. The investigators looked at 13 nutrient variables, but fiber was the only one that consistently yielded a health benefit. The study was published on February 27, 2012 in PLOS One.
