According to Traditional Chinese Medicine (TCM) theory, tofu is sweet in flavor and cool in nature, and it enters the spleen, stomach, and large intestine meridians. It has the effects of replenishing Qi, harmonizing the middle jiao, promoting the production of body fluids, moistening dryness, clearing heat, and detoxifying. It can be used to treat red eyes, thirst, and to counteract the toxicity of sulfur and burnt alcohol. However, excessive consumption of tofu is not beneficial to health.
Question 1: It can promote renal function decline.
Under normal circumstances, the plant protein ingested by the body undergoes metabolic changes, and most of it eventually becomes nitrogenous waste, which is excreted by the kidneys. As people age, the kidneys' ability to excrete waste decreases. If one does not pay attention to their diet and consumes a large amount of tofu, taking in excessive plant protein, it will inevitably increase the amount of nitrogenous waste produced in the body,加重 the burden on the kidneys, further decline renal function, and is not conducive to health.
Question 2: It can cause indigestion.
Tofu contains an extremely high amount of protein. Consuming too much at one time not only hinders the body's absorption of iron but can also easily lead to protein indigestion, causing discomfort symptoms such as bloating and diarrhea.
Question 3: It can promote the formation of arteriosclerosis.
American medical experts point out that soy products contain an extremely high amount of methionine. Under the action of enzymes, methionine can be converted to cysteine. Cysteine can damage the endothelial cells of the arterial wall, making it easy for cholesterol and triglycerides to deposit on the arterial wall and promoting the formation of arteriosclerosis.
Question 4: It can lead to iodine deficiency.
The soybeans used to make tofu contain a substance called saponin. It not only helps prevent atherosclerosis but also promotes the excretion of iodine in the human body. Long-term excessive consumption of tofu can easily lead to iodine deficiency, causing iodine deficiency disorders.
Question 5: It can trigger gout attacks.
Tofu contains a relatively high amount of purines. Gout patients with abnormal purine metabolism and patients with elevated blood uric acid levels are prone to gout attacks if they consume too much of it. Gout patients, in particular, should consume it in moderation.
Therefore, although tofu is good, it should not be eaten daily, and the amount consumed at one time should not be excessive. The elderly and patients with kidney disease, iron-deficiency anemia, gout, and arteriosclerosis should especially control their intake. According to TCM, tofu is inherently cold in nature. People with a cold stomach, those who are prone to diarrhea, bloating, or a weak spleen, as well as those with kidney deficiency who often experience nocturnal emissions, should also not eat too much.
