Researchers from the U.S. National Institute of Environmental Health Sciences concluded after studying 104 women who wished to become pregnant that coffee has a direct impact on conception. Among these women, those who drank more than one cup of coffee a day had only half the chance of becoming pregnant as those who did not drink this beverage. Therefore, they suggested that women who plan to become pregnant should reduce their coffee intake. Carrots
Carrots are rich in carotene, various vitamins, and other nutrients beneficial to the human body. Gynecological experts at Rutgers Medical School in New Jersey found that after women eat too many carrots, the large intake of carotene can cause amenorrhea and inhibit the normal ovulation function of the ovaries. Therefore, women who wish to conceive should not eat too many carrots. Sunflower Seeds
The protein portion of sunflower seeds contains components that inhibit the testes, which can cause testicular atrophy and affect normal reproductive function. Therefore, young people of childbearing age should not eat them in excess. Alcohol
Scientific research has proven that the main component of alcohol is ethanol. Ethanol can increase the concentration of catecholamines in the body, cause vascular spasms, lead to underdeveloped testes, and even cause testicular atrophy. This can cause structural changes in sperm production, insufficient secretion of male hormones such as testosterone, and feminizing symptoms such as a higher-pitched voice and enlarged breasts. Such individuals are prone to male infertility, and even if they conceive, the likelihood of the next generation having deformities is also high. In women, it can lead to irregular menstruation, amenorrhea, abnormal egg production, loss of libido, or cessation of ovation. Garlic
Excessive consumption of garlic can deplete a person's vital energy and has a significant spermicidal effect. If young people of childbearing age consume too much, it has an adverse effect on fertility, so it should not be eaten in excess. Roasted Beef and Lamb
Eating roasted beef and lamb is a habit for residents in Inner Mongolia, Xinjiang, and other regions. Some people have found that a few women who love to eat roasted lamb give birth to children with intellectual disabilities, paralysis, or deformities. After investigation and modern medical research, these women and their deformed children were victims of Toxoplasma gondii infection. Toxoplasmosis is also called toxoplasmosis. This parasite is invisible to the naked eye. It mainly causes infections in humans, livestock, and poultry. The developmental stage of the protozoan that causes disease in humans and animals is called the trophozoite, which is shaped like a bow under a microscope, hence its name. Toxoplasmosis can infect at least 60 types of livestock or poultry. People can become infected when they have contact with these animals and eat their undercooked meat. A survey in Hubei Province found that the infection rate of livestock mainly supplied for meat was: 11.32% for pigs, 34.5% for sheep, 11.8% for chickens, and 9.4% for ducks. If you slaughter livestock and poultry and do not wash your hands before touching food, taste the saltiness of dumpling filling after mixing it with your hands, touch raw meat and then touch cooked food, use the same cutting board for raw and cooked food, use knives interchangeably for raw and cooked food, handle raw meat from a cold storage, sell meat, or roast meat... you can be contaminated with Toxoplasma gondii trophozoites at any time. As for women who love to eat roasted meat, it is just one link in the chain of easy infection with toxoplasmosis. Women infected with Toxoplasma gondii may have no obvious symptoms. When they become pregnant, the infection can be transmitted to the fetus through the uterus, causing fetal deformities. Toxoplasmosis is a major factor in fetal deformities. Therefore, it is necessary to have a Toxoplasma antibody test before marriage or pregnancy. Crude Cottonseed Oil
Long-term consumption of crude cottonseed oil can cause a person to suffer from sunstroke disease, with symptoms that appear after sun exposure, such as general weakness, little or no sweating, 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 after rats feed on feed containing crude cottonseed oil for about 4 months, their testes significantly shrink, germ cells are significantly reduced or even disappear, the uterus shrinks, the endometrium and glands atrophy, the ovaries mildly atrophy, and the renal parenchymal cells have mild edema. Adult men who take gossypol, an extract of cottonseed oil, at 60-70 mg per day for 40 days, have all their sperm killed in a short period, which gradually disappears from the semen; women can lead to amenorrhea or uterine atrophy. Therefore, young people of childbearing age should not consume it for a long time.
It should be noted that the nutrients in foods such as coffee, carrots, and sunflower seeds are essential for the human body. This article only limits the amount, while roasted beef and lamb, crude cottonseed oil, etc., should be listed in the forbidden food category.
