How to eat tofu is not good for physical and mental health

　　Tofu is a traditional food that ordinary people are most familiar with. It is rich in nutrients and contains rich calcium, protein, amino acids, lecithin, etc. But did you know? There is some knowledge in tofu, and if you eat it incorrectly, it may harm your health.

　　First, don’t eat too much tofu. It’s best to control it to 100-150 grams a day, otherwise it may lead to the following healthy question:

　　1. Indigestion. Tofu is rich in protein. Eating too much at one time will not only hinder the body's absorption of iron, but also easily cause protein indigestion, abdominal distension, and diarrhea and other discomfort symptoms.

　　2. Promote renal function decline. After plant protein is ingested by the human body, most of it is metabolized into nitrogenous waste and excreted by the kidneys. If you eat a large amount of tofu for a long time and consume too much plant protein, it will inevitably cause excessive nitrogen-containing waste in the body and increase the burden on the kidneys. Especially when the ability of the kidneys to excrete waste is reduced elderly , kidney function may decline further.

　　3. Promote the formation of arteriosclerosis. It has been reported abroad that the abundant amino acids in soy products can be converted into cysteine. When ingested by the human body, it will damage the endothelial cells of the arterial wall and easily cause cholesterol and triglycerides to be deposited on the arterial wall, promoting the formation of arteriosclerosis.

　　4. Promote gout attacks. Tofu contains a lot of purine, which can easily cause gout patients with purine metabolism disorders and patients with increased blood uric acid concentration to cause uric acid stones or gout attacks.

　　Secondly, when eating tofu, you should also pay attention to the combination to avoid the following troubles:

　　Low protein utilization. The soy protein contained in tofu lacks an essential amino acid, methionine. If eaten alone, the protein utilization rate is low. Solution: Eat it with fish, eggs, meat and other methionine-rich ingredients, such as fish head tofu and tofu stir-fry egg , minced meat tofu, etc., can balance the ratio of the entire amino acid, which helps the protein in tofu to be fully absorbed.

　　Causes iodine deficiency. Soybeans contain a substance called saponin, which can cause excessive excretion of iodine in the human body. Excessive consumption of tofu for a long time can easily cause iodine deficiency. Solution: When eating tofu, don’t forget to pair it with some iodine-rich ingredients, such as kelp.

　　Formation of stones. Tofu contains high calcium. If it is often eaten together with vegetables with high oxalic acid content, it will produce calcium oxalate that is not easily absorbed and may form stones. Solution: If you want to eat tofu with spinach, water spinach, red amaranth, wild rice and other vegetables with high oxalic acid, be sure to blanch the vegetables to reduce the oxalic acid content.
