Born First, it promotes arteriosclerosis.
Soy products are extremely rich in 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 arteriosclerosis.
Second, it promotes gout attacks.
Tofu contains a lot of purine. For gout patients with abnormal purine metabolism and patients with increased blood uric acid concentration, eating more tofu can easily lead to gout attacks.
Third, it leads to iodine deficiency.
The soybeans used to make tofu contain saponins, which accelerate the excretion of iodine in the body. Long-term excessive consumption of tofu can easily cause iodine deficiency and lead to iodine deficiency disease.
Fifth, increase the burden on the kidneys.
Under normal circumstances, the plant proteins that people eat into the body undergo metabolism, and finally most of them become nitrogen-containing waste and are excreted by the kidneys. As people age, the ability of the kidneys to excrete waste decreases. At this time, if you don't pay attention to your diet, eat a lot of tofu, and consume too much plant-based protein, it will inevitably increase the nitrogenous waste generated in the body, increase the burden on the kidneys, and be detrimental to the body. healthy。
Sixth, yes sperm harmful.
Preliminary research in the laboratory of British scientists has found that a phytochemical in soybeans may be harmful to sperm. British researchers say a phytochemical found in soybeans may be harmful to sperm, Reuters reports male of fertility.
Research by Professor Lynn Fraser of King's College London shows that genistein, which mimics the effects of estrogen, affects the sperm of mice. "Human sperm are more sensitive to genistein than mouse sperm," Fraser told a fertility conference. ”
In experiments, Frazier found that a small amount of this chemical can destroy male sperm, causing the sperm to be "consumed" when it swims to the egg, causing the sperm to lose fertility. Effects on sperm found in the laboratory may also not be directly related to real life. But the concern is whether the chemicals affect mature sperm, said Dr. Alan Pacey of the University of Sheffield in England.
trying to conceive female Be careful with soy products. Frazier also said that if women eat soy and other foods rich in genistein, the impact on male fertility may be greater, because this chemical is likely to affect the sperm when it enters the female body to fertilize the woman. "The mother's exposure to the substance is probably more dangerous than the father's exposure to the substance," Fraser explained. ”
Although this is preliminary research, Fraser speculates that these conclusions may have implications for women trying to conceive. She told a meeting of the European Society of Human Reproduction and Embryology: "Based on our research, if you have a habit of eating a lot of soy products, you should restrict your diet around the time of ovulation. ” A link to a special gene helps British Prime Minister Blair get pregnant at an advanced age. When Sheree, the wife of British Prime Minister Blair, gave birth to her fourth child, Leo, at the age of 45, Blair's "ability" was widely praised by British society.
But Leo's birth is likely to be down to Mrs Blair's genes rather than the Prime Minister himself. Recently, scientists found a specific gene in women who can still have children naturally after the age of 45. Hadassah University of Jerusalem Hospital Researchers studied 250 German-Jewish women and found that they had a gene in their ovaries that seemed to prevent DNA damage and cell death.
