It is best not to drink soybean milk on an empty stomach in the morning, because it will be digested directly as calories, losing its nutritional value and increasing the digestive burden of the stomach and intestines. Soybean milk contains a variety of nutrients, which are beneficial to health when consumed regularly. It is best to consume soybean milk with carbohydrates, so that the soybean milk can be fully utilized, maximizing its nutritional value and better absorbed by the body.
From a nutritional perspective, soybean milk is a beverage rich in protein, but it can only be utilized for the construction of new tissues and repair of old tissues when consumed after sufficient starch-containing foods. If consumed on an empty stomach, it will only be consumed as calories instead of starch, resulting in the waste of protein and an imbalance in body nutrition, which may increase the burden on the digestive and urinary systems. Therefore, it is not economically efficient.
The correct way to drink soybean milk is to consume it along with carbohydrate-rich foods such as biscuits, steamed bread, and bread, or to consume it 1 to 2 hours after breakfast. This allows the soybean milk to undergo more thorough enzymatic digestion in the stomach with gastric juice, maintains a balanced diet, facilitates digestion and absorption, maximizes the nutritional effect of protein, and allows the nutrients to be fully absorbed by the body, thereby promoting human health.
