A Japanese study has found that very low intakes of saturated fatty acids actually increase the risk of dying from a stroke, an inverse association that runs counter to current thinking. The research team hypothesized that saturated fat intake is associated with the risk of death from cardiovascular disease in Japanese, whose consumption of saturated fat is low. They studied food-frequency questionnaire data compiled in 1988-90 from more than 58,000 adults (ages 40-79), following the participants for more than 14 years to determine deaths from several types of stroke as well as heart diseases. It was found that saturated fat intake was inversely associated with overall stroke mortality, with especially strong associations for ischemic stroke and the rarer but deadlier intraparenchymal hemorrhage.
