Many population studies have shown that people who eat significant amounts of legumes (e.g., beans, split peas, chickpeas, and lentils) tend to weigh less. They also have slimmer waists, less obesity, and lower blood pressure compared to people who don’t eat many legumes.47 But couldn’t these benefits be due not to the legumes themselves but to the fact that people who eat more legumes may eat a healthier diet in general?
