Black beans and soybeans are close relatives and belong to the soybean family, but there are differences in varieties and similar nutritional components. Therefore, black soybean milk and yellow soybean milk are rich in nutrients such as protein, potassium, magnesium, calcium and B vitamins, as well as soluble dietary fiber and isoflavones. The difference is that soybean milk contains a small amount of carotene, while black soybean milk contains chlorophyll and melanin, which are beneficial to health. The content of protein, potassium and vitamins in black beans is slightly higher than that in soybeans, which has stronger functions of clearing fire, benefiting water and resisting oxidation, so drinking black bean milk is better.

Suggestion: Don't drink too much soybean milk at one time, which may lead to "protein's indigestion due to overeating", diarrhea, bloating and other symptoms. In addition, eating some starchy foods such as bread, cakes and steamed bread while drinking soybean milk can fully hydrolyze protein and gastric juice under the action of starch and fully absorb nutrients.
