A recent study from the Harvard School of Public Health found that people who eat a handful of nuts per day are 20 percent less likely to die early than those who skip them. In addition to lower early death rates, the researchers found that people who consumed seven or more handful-sized servings per week saw a 25 percent reduction in death from cardiovascular disease, and an 11 percent reduction in death from cancers. Each nut has a unique profile and features different benefits: walnuts for the heart; almonds for weight loss and pistachios for brain health. Go nuts for nuts!
