Black soybean milk is able to provide the body with protein and other nutrients contained in black beans and is not effective for the organism, but it is not recommended for people who are allergic to black beans. Black soybean milk is made from black beans, which are rich in nutrients including protein, fat and dietary fiber. 100 ml of unsweetened black soybean milk contains 16 calories, of which 1.1 grams of carbohydrates, 0.7 grams of fat, 1.8 grams of protein, 1.1 grams of dietary fiber, 15 micrograms of vitamin A, 48 milligrams of potassium, 10 milligrams of calcium, and vitamin E 0.8 milligrams. Black soybean milk is a good source of protein as well as dietary fiber. Black soybean milk itself is not a medicinal food, so it does not generally have any therapeutic benefits for the human body. In addition, if the body itself is allergic to black beans, it should not be consumed, so as not to cause serious discomfort.
