Diets for the heart
Information about two clinically researched diets for heart disease, the DASH and Mediterranean diets, is widely available. You can get detailed information about the DASH, as well as recipes and meal plans, for free from the National Heart, Lung, and Blood Institute or in bookstores (The DASH Diet Action Plan by Marla Heller or The DASH Diet for Hypertension by Thomas Moore and Mark Jenkins). A number of books have been written about the Mediterranean diet, from How to Eat Well and Stay Well the Mediterranean Way, written in 1959 by pioneering nutrition researcher Ancel Keys and his wife, Margaret, to Your Heart Needs the Mediterranean Diet, published in 2007 by Emilia Klapp, a registered dietitian.
It's harder to find specific information on two other clinically tested heart-disease diets, the OmniHeart and Portfolio diets. We gleaned the information below from reports in medical journals.
The Optimal Macronutrient Intake Trial to Prevent Heart Disease (OmniHeart, for short) higher-protein diet is similar to the DASH diet but with more protein and less carbohydrate.
