The amino acid composition of black bean protein is similar to that of animal protein. It is rich in lysine and is close to the proportion required by the human body, so it is easy to digest and absorb. Black bean fat contains more unsaturated fatty acids, has a low melting point, is easy to digest and absorb, and will not be deposited on the blood vessel walls. Its biggest feature is that it contains plant sterols. Plant sterols are not only absorbed by the body, but also inhibit the absorption of cholesterol. Therefore, black beans are an ideal health product for middle-aged and elderly people with arteriosclerosis. The calcium contained in black beans is an excellent source of calcium for the human body.
