be vigilant! Eating too much tofu can damage kidney function

Be alert! Eating too much tofu will damage renal function. Bean curd is one of the most popular cooking materials, which is made from soybeans, green beans and black beans by soaking, refining, filtering, boiling, refining, solidification and molding. The protein content of tofu and tofu products is higher than that of soybean, and tofu protein is a complete protein, which not only contains eight kinds of amino acids necessary for human body, but also has a proportion close to human body's needs, with high nutritional potency.

Tofu also contains fat, carbohydrates, vitamins and minerals. According to the theory of TCM, it can be used to relieve thirst, invigorate the spleen, cool the eyes, and cool the large intestine. But although tofu is good, there are disadvantages in eating too much tofu, and too much tofu is harmful to health.

1. Promote the decline of renal function

Under normal circumstances, most of the plant protein that people eat into the body is metabolized, and finally becomes nitrogen-containing waste, which is discharged from the body by the kidney. In old age, the ability of excreting waste by the kidney is reduced. At this time, if we do not pay attention to diet, eat a lot of tofu, and eat too much plant protein, it is bound to increase the nitrogen-containing waste generated in the body, increase the burden on the kidney, and further decline the renal function, which is not conducive to health.

2. Cause indigestion

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

3. Promote arteriosclerosis

American medical experts pointed out that soybean products are rich in methionine, which can be converted into cysteine under the action of enzyme. Cysteine can damage the endothelial cells of the arterial wall, easily make cholesterol and triglyceride deposition on the arterial wall, and promote the formation of atherosclerosis.

4. Lead to iodine deficiency

Soybean tofu contains a substance called saponin, which can not only prevent atherosclerosis, but also promote the excretion of iodine in human body. Long term excessive consumption of tofu is easy to cause iodine deficiency, leading to iodine deficiency disorders.

5. Promote gout attack

Tofu contains more purines. Gout patients with abnormal purine metabolism and patients with increased serum uric acid concentration are more likely to have gout attack, especially gout patients should eat less.

It can be seen that although tofu is good, it is not suitable to eat it every day, and it should not be eaten too much at one time. The elderly and patients with kidney disease, iron deficiency anemia, gout and arteriosclerosis should control their consumption. Traditional Chinese medicine believes that tofu is cold, stomach cold, diarrhea, abdominal distension, spleen deficiency, and kidney deficiency are not suitable to eat more.
