Higher nut consumption was linked to a reduced rate of death from all causes and from cardiovascular disease, in a sample of more than 200,000 people of low-socioeconomic status. The results were consistent for blacks, whites and Asians. Peanuts were the most prevalent form of nut consumption. Easting more peanuts might be a cost-effective way of improving cardiovascular health in various socioeconomic groups. Don’t worry about the high calorie content of nuts –  eaters are generally leaner.
