New data challenges decades of nutritional guidelines
A 40-year-old study that examined the connection between dietary fats and heart health was finally fully published last week in the British Medical Journal and revealed evidence that directly contradicts widely accepted nutritional dogma, including the Dietary Guidelines for Americans. The study, known as the Minnesota Coronary Experiment, followed thousands of institutionalized patients, comparing the influence of a diet low in saturated fat to one that was naturally higher in fat. The results showed that patients deprived of saturated fat actually suffered more coronary-related events despite lowering cholesterol, compared with the group on the unrestricted diet. "Had this research been published 40 years ago, it might have changed the trajectory of diet-heart research and recommendations," said researcher Daisy Zamora.
