Every type of food contains a variety of elements; while one may be beneficial to the human body, another may pose a danger to health.
Sunflower Seeds The protein portion of sunflower seeds contains components that inhibit the testes, which can lead to testicular atrophy and affect normal reproductive function. Therefore, young people of childbearing age should not consume them in large quantities.
Alcohol
Scientific research has proven that the main component of alcohol is ethanol. Ethanol can increase the concentration of catecholamines in the body, cause blood vessel spasms, lead to underdeveloped testes, and even cause testicular atrophy. This results in structural changes in sperm production, a deficiency in male hormones like testosterone, and the appearance of feminizing characteristics such as a higher-pitched voice and enlarged breasts. Such individuals are prone to male infertility, and even if they conceive, there is a higher likelihood of the next generation having birth defects. In women, it can lead to irregular menstruation, amenorrhea, abnormal egg production, loss of libido, or cessation of ovulation.
Garlic
Excessive consumption of garlic can deplete a person's vital energy and has a significant sperm-killing effect. For young people of childbearing age, eating too much can adversely affect fertility, so it should not be consumed in large quantities.
Roasted Beef and Lamb
Eating roasted beef and lamb is a habit for residents in Inner Mongolia, Xinjiang, and other regions. It was discovered that a few women who loved eating roasted mutton gave birth to children with intellectual disabilities, paralysis, or deformities. After investigation and modern medical research, it was found that these women and their deformed children were victims of *Toxoplasma gondii* infection. People can often become infected when they come into contact with livestock and poultry infected with toxoplasmosis and eat undercooked meat from these animals.
Hubei Province once conducted a survey on the infection rate of livestock and poultry that are the main sources of meat: pigs 11.32%, sheep 34.5%, chickens 11.8%, and ducks 9.4%. If you slaughter livestock and poultry and do not wash your hands before handling food, taste the filling for dumplings after handling raw meat, touch cooked food after handling raw meat, use the same cutting board for raw and cooked food, use knives interchangeably for raw and cooked food, or handle raw meat, sell meat, or roast meat from a cold storage... you can be contaminated with *Toxoplasma gondini* trophozoites at any time. As for women who love eating roasted meat, it is just one link in the chain of easy infection with toxoplasmosis. Women infected with *Toxoplasma gondii* may not have any obvious symptoms. When they become pregnant, the infection can be transmitted to the fetus through the uterus, causing fetal deformities. *Toxoplasma gondii* infection is a major factor in fetal deformities. Therefore, it is necessary to undergo antibody tests for toxoplasmosis before marriage or pregnancy.
Crude Cottonseed Oil
Long-term consumption of crude cottonseed oil can cause a condition known as "sunstroke disease," with symptoms that appear after sun exposure, including general weakness, little sweat, hot and flushed skin, palpitations and shortness of breath, dizziness, numbness in the limbs, and loss of appetite. A more serious effect is the damage to the reproductive system. Experimental studies have shown that when rats are fed a diet containing crude cottonseed oil for about 4 months, their testes significantly shrink, germ cells are markedly reduced or even disappear, the uterus shrinks, the endometrium and glands atrophy, the ovaries undergo mild atrophy, and the renal parenchymal cells have mild edema. When adult men take gossypol, an extract of crude cottonseed oil, at 60-70 mg per day for 40 days, all their sperm are killed in a short period and gradually disappear from the semen. In women, it can lead to amenorrhea or uterine atrophy. Therefore, young people of childbearing age should not consume it long-term.
