Lentils, a small but nutritionally mighty member of the legume family, are a very good source of cholesterol-lowering fiber. Not only do lentils help lower cholesterol, they are of special benefit in managing blood-sugar disorders since their high fiber content prevents blood sugar levels from rising rapidly after a meal. But this is far from all lentils have to offer. Lentils also provide good to excellent amounts of seven important minerals, our B-vitamins, and protein—all with virtually no fat. The calorie cost of all this nutrition? Just 230 calories for a whole cup of cooked lentils. This tiny nutritional giant fills you up—not out.
