Tofu is one of the most common and popular cooking ingredients, made from raw materials such as soybeans, green beans, and black beans, through processes including soaking, grinding, filtering, boiling, adding coagulant, solidifying, and shaping.
The protein content in tofu and tofu products is higher than that in soybeans. Moreover, tofu protein is a complete protein, containing all eight essential amino acids required by the human body, with a ratio that closely matches the body's needs, giving it a high nutritional value. Tofu also contains fats, carbohydrates, vitamins, and minerals. According to Traditional Chinese Medicine (TCM) theory, tofu is sweet in flavor and cool in nature, and it affects the spleen, stomach, and large intestine meridians. It is believed to have 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 conditions such as red eyes, diabetes, and to counteract the toxicity of sulfur and liquor. However, although tofu is beneficial, excessive consumption can have drawbacks and may harm health.
Be aware of the pitfalls of tofu!
Question 1: It can cause indigestion.
Tofu is extremely rich in protein. Consuming too much at once 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 2: It may promote kidney function decline.
Under normal circumstances, plant proteins consumed by the body undergo metabolic changes, and most of them eventually become 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 large amounts of tofu, taking in excessive plant-based protein, it will inevitably lead to an increase in nitrogenous waste in the body,加重 the burden on the kidneys, further decline kidney function, and be detrimental to health.
Be aware of the pitfalls of tofu! Question 3: It can promote atherosclerosis.
American medical experts point out that soy products contain extremely high levels of methionine. Under the action of enzymes, methionine can be converted to homocysteine. Homocysteine can damage the endothelial cells of the arterial walls, making it easy for cholesterol and triglycerides to deposit on the arterial walls and promoting the formation of atherosclerosis. Be aware of the pitfalls of tofu!
Question 4: It can lead to iodine deficiency.
Soybeans used to make tofu contain a substance called saponin. Saponin not only helps prevent atherosclerosis but also promotes the excretion of iodine from the 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 relatively high levels 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.
Thus, while tofu is beneficial, it should not be eaten daily, and consumption should not be excessive in a single sitting. The elderly and patients with kidney disease, iron-deficiency anemia, gout, and atherosclerosis should especially control their intake. According to TCM, tofu has a cool nature. People with a cold stomach, those who are prone to diarrhea, bloating, or a weak spleen, as well as individuals with kidney deficiency who often experience nocturnal emissions, should also not consume it in large amounts.
