1, soybean will produce too much gas in the process of digestion and absorption, causing abdominal distension, so people with digestive dysfunction and chronic digestive tract diseases should eat as little as possible.

2, the elderly should eat soybeans in moderation, not greedy. Because the functions of various organs of the elderly are weakened and they consume too much soy products, the non-protein nitrogen decomposed incompletely by protein will be excreted through the kidneys, which will increase the burden on the kidneys.

3. Soybean contains a lot of purine alkaloids, which will increase the metabolic burden of liver and kidney. Therefore, when liver and kidney organs have serious diseases, pay attention to eating less or not eating soybeans.

4, eat less dry fried soybeans. Because fried soybeans will not only hinder the absorption of protein by human body, but also harmful factors such as trypsin inhibitor, urease and hemagglutinin in soybeans cannot be decomposed under dry and hot conditions.
