Although stir-fried soybeans and oil-roasted soybeans are fragrant and delicious, their nature is warm and drying, making them difficult to digest. Excessive consumption can lead to indigestion, bloating, dry mouth, and constipation. Those with a weak spleen and stomach should not eat them. Soybeans contain trypsin inhibitors, which can easily cause symptoms such as nausea, vomiting, and diarrhea. However, these trypsin inhibitors can be decomposed and destroyed by high temperatures, so they should be cooked thoroughly at high heat to facilitate digestion and absorption. Saponins in soybeans can promote the excretion of trace element iodine in the human body. Long-term excessive consumption of soy products can lead to iodine deficiency, causing simple goiter. Iodine deficiency in children can directly affect their growth and development, leading to a decline in intelligence. Soy products are rich in calcium, which is beneficial for supplementing the body's calcium. However, if the blood calcium level is too high, it will hinder the absorption of zinc. Zinc deficiency in children can lead to delayed development, loss of appetite, anorexia, and can also affect memory, making them more susceptible to colds, pneumonia, oral ulcers, and geographic tongue. Therefore, children should pay attention to a balanced diet and should not rely on a single source of soy products for a long period. Black beans:
Frying them can easily damage the spleen, and those who are weak should not eat them. Black beans are relatively hard and difficult to digest, so those with fullness in the middle or poor digestive function should eat them sparingly or not at all. In addition, like soybeans, they must never be swallowed whole without thorough chewing. Mung beans:
Those with a weak spleen and stomach should not eat too many. When making mung bean soup, it is not advisable to use alum, as it will destroy the original fresh and fragrant flavor of the soup and also damage some of the nutrients.
Adzuki beans:
Adzuki beans are sweet and sour in nature and promote urination. Excessive consumption can lead to weight loss, so those who are thin or have frequent urination should not eat them. Broad beans:
Broad beans are stagnating in nature, and excessive consumption can cause bloating. Those with a weak spleen and stomach should not eat many. A small number of people may develop "favism" after eating broad beans. The symptoms include sudden fatigue, dizziness, nausea, chills, fever, body aches, listlessness, enlarged liver and spleen, difficulty breathing, and even coma. The skin and whites of the eyes turn yellow, and the urine is the color of soy sauce. Studies have shown that favism has a clear genetic predisposition. Therefore, parents with a history of broad bean allergy need to be especially cautious and should be very careful about their children eating broad beans. Lima beans:
Lima beans contain a toxic protein, and the pods contain hemolysin and alkaloids. These substances must be destroyed by high heat; if not heated enough, poisoning symptoms such as nausea, vomiting, abdominal pain, and dizziness may occur after consumption. The best way to prevent lima bean poisoning is to heat them thoroughly to completely decompose the toxic substances. Peas:
Excessive consumption can cause bloating, and those with a weak spleen and stomach should use them with caution.
