Precautions for tofu:

1. Eating too much tofu may lead to renal failure.

Under normal circumstances, protein, a plant that people eat in the body, undergoes metabolic changes, and finally most of it becomes nitrogen-containing waste. Eating more tofu and vegetable protein will inevitably increase the nitrogen-containing waste produced in the body, increase the burden on the kidneys and be harmful to health.

2. Eating too much tofu will lead to indigestion.

Tofu is rich in protein. Eating too much at a time not only hinders the absorption of iron, but also easily causes protein's indigestion, abdominal distension, diarrhea and other discomfort symptoms.

3. Excessive consumption of tofu will promote arteriosclerosis.

Soybean products are rich in methionine, and homocysteine is an important intermediate product of methionine metabolism. Studies have shown that homocysteine can enhance lipid peroxidation by changing the structure and function of cells, and affect the concentration of various active molecules related to coagulation system and atherosclerosis.

Eating too much tofu will lead to iodine deficiency.

Soybeans that make tofu contain a substance called saponin, which can not only prevent arteriosclerosis, but also promote the excretion of iodine in human body. Long-term excessive consumption of tofu can easily lead to iodine deficiency, leading to iodine deficiency disorders.
