The nutritional value of soybeans cooked directly is not as high as that of soymilk for the following reasons:
The nutritional value of soybeans is very high, but eating them directly affects the absorption of proteins, resulting in intestinal flatulence and other phenomena. Consumption of whole soybeans its protein absorption rate of about 65%, and processed into soy milk absorption rate can grow to 92% to 96%. Homemade soybean milk at home, you can also green beans, red beans, black beans, peanuts and other types of food and soybeans mixed together to make soybean milk, a variety of food nutrients complement each other, so that soybean milk nutrients more balanced.
Drinking soybean milk should pay attention to the dry and thin collocation, so that the protein in the soybean milk in the role of starchy food, more fully absorbed by the body. If you eat some vegetables and fruits at the same time, the nutrition is more balanced. Soybean milk is cold, so the spleen and stomach cold, diarrhea, bloating people to drink less or not drink. It should also be noted that homemade fresh soy milk should be drunk within 24 hours.

Nutrition
Soybeans don't just refer to soybeans, it also contains black beans and green beans. Soybeans are comprehensive and rich in nutrition, with protein content two times higher than that of pork and 2.5 times the content of eggs. The protein content is not only high, but also of good quality. The amino acid composition of soy protein and animal protein is similar, in which the amino acids are closer to the ratio of human needs, so it is easy to be digested and absorbed. If the soybean and meat food, egg food with the food to eat, its nutrition can be compared with the nutrition of eggs and milk, and even more than the nutrition of eggs and milk.
Soybean fat also has a high nutritional value, this fat contains a lot of unsaturated fatty acids, easy to be digested and absorbed by the human body. And soybean fat can block the absorption of cholesterol, so soy is an ideal nutrient for patients with atherosclerosis.
The dietary fiber in soybean residue plays a pivotal role in promoting good digestion and excretion of solid waste. A moderate amount of fiber supplementation can enlarge and soften the food in the intestines and promote intestinal peristalsis, which speeds up bowel movements, prevents constipation and reduces the risk of bowel cancer. At the same time, dietary fiber has the obvious function of lowering plasma cholesterol, regulating gastrointestinal function and insulin level.
Soybean meal is the residual meal by-product of soybeans extracted from fats and oils by low-temperature (40-60 degrees Celsius) leaching, and is in the form of coarse powder. Because not subjected to temperature, soybean antitrypsin, urease, hemagglutinin, saponin, goiter-inducing factor will not be destroyed. Soybean cake meal is the most widely used, the largest amount of plant protein raw materials.
