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 getting pregnant compared to those who did not drink this beverage. Therefore, they suggest that women who plan to become pregnant should reduce their coffee intake.
It should be noted that the nutrients in foods like coffee, carrots, and sunflower seeds are essential for the human body. This article only recommends limiting the intake of such foods, whereas roasted beef and mutton, and crude cottonseed oil should be listed as forbidden foods. Carrot
Carrots are rich in carotene, various vitamins, and other beneficial nutrients for the human body. Gynecological experts at Rutgers Medical School in New Jersey found that after consuming excessive amounts of carrots, women's high intake of carotene can cause amenorrhea and inhibit the normal ovulatory 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 consume them in large quantities. Alcohol
Scientific research has proven that the main component of alcohol is ethanol, which 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 like testosterone, and lead to feminine 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 birth defects in the next generation. 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 spermicidal effect. Young people of childbearing age should not eat too much of it, as it has an adverse effect on fertility. Roasted Beef and Mutton
Eating roasted beef and mutton is a habit for residents in Inner Mongolia, Xinjiang, and other regions. It was discovered that a few women who loved eating roasted lamb gave birth to children with intellectual disability, paralysis, or deformities. After investigation and modern medical research, these women and their deformed children were victims of *Toxoplasma gondii* infection. People can be infected when they come into contact with livestock and poultry infected with toxoplasmosis and eat undercooked meat from these animals.
A survey in Hubei Province found that the infection rates among major livestock supplying meat were: 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 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 from a cold storage, sell meat, or roast meat, you can be contaminated with *Toxoplasma* trophozoites at any time. As for women who love to eat roasted meat, this is just one link in the chain of easy infection with toxoplasmosis. Women infected with *Toxoplasma* may not have obvious symptoms, but when they become pregnant, the infection can be transmitted to the fetus through the uterus, causing fetal deformities. *Toxoplasma* infection is a major cause of fetal deformities. Therefore, it is necessary to undergo a *Toxoplasma* antibody test before marriage or pregnancy. Crude Cottonseed Oil
Long-term consumption of crude cottonseed oil can cause a condition known as "sun sickness," 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. More serious effects are damage to the reproductive system. Experimental studies have shown that after rats were fed feed containing crude cottonseed oil for about four months, their testes significantly shrank, spermatocytes were significantly reduced or even disappeared, the uterus shrank, and the endometrium and glands atrophied; the ovaries showed mild atrophy, and the kidney parenchymal cells had mild edema. Adult men who took gossypol, an extract of cottonseed oil, at 60-70 mg per day for 40 days had all their sperm killed in a short period, and the sperm gradually disappeared 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.
