First, it promotes arteriosclerosis.
Bean products contain extremely rich methionine, which can be converted into cysteine under the action of enzymes. It damages the endothelial cells of the arterial wall, causing cholesterol and triglycerides to deposit on the arterial wall, leading to the formation of arteriosclerosis.
Second, it triggers gout attacks.
Tofu contains a relatively high amount of purines. Gout patients with abnormal purine metabolism and patients with elevated blood uric acid concentration are more likely to suffer from gout attacks if they eat too much tofu.
Third, it leads to iodine deficiency.
The saponins in soybeans used to make tofu can accelerate the excretion of iodine in the body. Long-term excessive consumption of tofu can easily lead to iodine deficiency, causing iodine deficiency diseases.
Fourth, it increases the burden on the kidneys.
Under normal circumstances, the plant protein ingested by the human body is metabolized, and most of it eventually becomes nitrogen-containing waste, which is excreted by the kidneys. As people age, the kidneys' ability to excrete waste decreases. If dietary habits are not managed at this time, excessive consumption of tofu and intake of too much plant-based protein will inevitably increase the amount of nitrogen-containing waste in the body,加重加重 the burden on the kidneys, which is not conducive to health.
Fifth, it is harmful to sperm.
Preliminary laboratory research by British scientists has found that a phytochemical in soybeans may be harmful to sperm. According to Reuters, British researchers claim that a phytochemical found in soybeans may be harmful to sperm, affecting male fertility.
Sixth, it renders sperm infertile.
Research by Lynn Fraser, a professor at King's College London, shows that genistein, which mimics the effects of estrogen, affects mouse sperm. Fraser said at a fertility conference: "Human sperm is more sensitive to genistein than mouse sperm."
