Soybeans, green beans and black beans are collectively referred to as soybeans. Because of its high nutritional value, protein alone is twice that of lean meat, twice that of eggs and 1 times that of milk, so it is called "king of beans", "meat in the field" and "green milk", and it is the most respected food among hundreds of natural foods.
Soybean protein and stigmasterol in soybean can obviously change half-swallowing and half-vomiting, reduce blood lipid and cholesterol, and thus reduce the probability of cardiovascular disease. Soybean fat is rich in nonalcoholic fatty acids and soybean phospholipids, which has the functions of maintaining vascular elasticity, strengthening brain and preventing fatty liver formation.
Soybean will produce too much gas in the process of digestion and absorption, causing abdominal distension, so the digestive function is poor, and people with chronic digestive diseases should eat as little as possible.
