Green gram is a small, oval-shaped bean that you can cook before or after soaking. Once cooked, the bean is sweet and soft in texture, and it is easily digestible, so it doesnt produce flatulence like many other legumes. The mung bean has an olive green husk and a dark-mustard-colored interior. The dried bean is often split to expedite cooking and sold as green dal. If it has been hulled before splitting, only the yellow endosperm remains, and the bean goes by various names including moong dal or mung dal. Green gram dal, which still has the husks, maintains its shape better when cooking, while moong dal becomes soft and mushy like porridge. Because of their soft consistency, dals are used for stews, soups, salads and desserts.
Like other beans, the mung bean is a rich source of low-fat protein. One cup of mature, boiled beans contains 14 g of protein, according to the U.S. Department of Agriculture. Unlike many other plant based sources of protein, mung beans have a wide amino-acid profile, providing at least some of every type of amino acid. Green gram dal contains virtually no Trans or saturated fats. It does contain a small amount of healthy monounsaturated and polyunsaturated fat.
