Beans, actually legumes (see Vegan Journal for an explanation of terms), are associated with many health benefits including a lower risk of heart disease (1) and type 2 diabetes (2). A new study suggests that higher consumption of legumes is associated with a lower risk of mortality from all causes and a lower risk of dying from stroke (3).
This study combined results from 31 other published studies using a technique called meta-analysis. Higher intakes of legumes, compared with lower intakes, were not associated with a lower risk of dying from cardiovascular disease or from cancer but were associated with a lower risk of dying from all causes. A 50 gram increase in legume consumption was associated with a 6% lower risk of all-cause mortality. Fifty grams of legumes is about 1-3/4 ounces or about ¼ cup of cooked legumes.
