Tofu is made from soybeans, green beans, black beans as raw materials, processed by soaking, refining, filtering, boiling, thinning, solidifying, and forming. It is one of the most widely used and most popular cooking ingredients. Chinese medicine books record: tofu, sweet and cool, with Qi and the effectiveness of detoxification in Sheng Jin.

Under normal circumstances, the plant protein that people eat into the body undergoes metabolic changes, and most of them become nitrogenous wastes and are excreted by the kidneys. In the elderly, the ability of the kidneys to excrete waste decreases. If you do not pay attention to your diet, eat large amounts of tofu, and consume excessive amounts of plant protein, it will inevitably increase the amount of nitrogen-containing waste generated in the body, increase the burden on the kidneys, and make kidney function. Further decline is not conducive to good health.

Patients with kidney deficiency

Tofu contains extremely rich in protein, and eating too much at a time not only hinders the body's absorption of iron, but also easily causes protein indigestion and bloating and diarrhea.

Promote arteriosclerosis

Cysteine ​​can damage endothelial cells in the arterial wall, easily depositing cholesterol and triglyceride on the arterial wall and promoting the formation of arteriosclerosis.

Lead to iodine deficiency

The soybeans that make tofu contain a substance called saponin that not only prevents atherosclerosis, but also promotes the excretion of iodine in the body. Long-term excessive consumption of tofu can easily cause iodine deficiency, leading to iodine deficiency disorders.

Chemical Toxicants "Stir" Stinky Tofu

Stinky tofu is usually made through procedures such as fermentation, pickling, and soup preparation. During the fermentation process, it is easily contaminated by microorganisms and it also volatilizes a large amount of base nitrogen. White bean curd should be turned into stinky tofu. Under normal circumstances, white tofu is left for a period of time to allow natural fermentation and odor. But in this case, the time is too long to affect business. In order to increase production, some unscrupulous hawkers simply inject chemical ingredients into white bean curd, which catalyzes the rapid deterioration of tofu. The chemical components remaining in tofu are toxic and harmful to the human body.
