American media awarded the "Alternative Nobel Prize", among which Coke Sperm Killer won the "Alternative Nobel Prize" chemistry prize. Anderson, the award-winning scientist, has heard the legend of Coca-Cola contraception for many years. The resolution and some colleagues used it to verify that Coca-Cola can indeed kill sperm.
In fact, in addition to Coke, there are many unknown spermicidal foods in real life. They confuse people with their delicious taste, and may have been doing evil around you for many years. So, what are these spermicidal foods?
1、 Fried chicken
Some research reports pointed out that the starch food in barbecue and fried contains carcinogenic poison acrylamide, which can lead to male oligospermia and weak sperm. In addition, heavy metal cadmium and pesticide residues are toxic to sperm.
Some experts also found that the decrease of sperm and vitality of oligozoospermia patients was related to the lack of zinc, a trace element. Therefore, eating more zinc rich foods such as oysters, shrimp skin, animal liver, laver, sesame, peanuts, beans, etc. can ensure that the "essence" is full of energy.
2、 Beer
If you don't know whether your kidney has problems, you'd better go to the hospital for blood and urine tests. If you have kidney disease and drink beer without restriction, uric acid deposition will lead to renal tubular obstruction and renal failure.
3、 Coffee
Coffee is refreshing because the caffeine it contains stimulates people's sympathetic nerves. Sympathetic nerve controls all activities of the day. When it is stimulated, people will be refreshed and energetic. The parasympathetic nerve is specialized in the physiological, erectile and other sex-related activities of people at night, and its relationship with the sympathetic nerve belongs to the relationship between the exterior and the interior. When the sympathetic nerve activity is frequent, the relatively weak parasympathetic nerve will be suppressed, and the clinical manifestation is the decline of sexual desire.
Therefore, people with large emotional fluctuations and sympathetic nerve excitability should not drink caffeinated drinks such as coffee before sex to avoid suppressing parasympathetic nerve and reducing sexual desire.
4、 Tofu
People often say that eating soy products is beneficial to the body, especially tofu. The absorption rate of protein contained in tofu in human body is as high as 90%. However, Dr. George Chavaro of Harvard University School of Public Health tracked 99 men from 2000 to 2006, and found that men who ate soy products every day had only 41 million sperm per milliliter of semen, significantly lower than men who ate less soy products. However, if the number of sperm per milliliter of semen is less than 20 million, the sperm concentration is too low and it is easy to be sterile. In addition, this link is more obvious in obese men.
Chavaro's research shows that soybean products have adverse effects on male reproductive system, especially sperm production. Soybean is rich in isoflavone phytoestrogens. If you take too much, it will affect the level of male hormones in men, leading to a series of adverse consequences.
Is that not to eat? Neither is it. The key is the right amount. The so-called "moderate" refers to eating less than 3 times a week, about 100g each time. This will not only ensure nutrition, but also cause "side effects".
5、 Milk tea
At present, the pearl milk tea on the market is mostly made of milk essence, pigment, essence, cassava powder (referring to the pearl in milk tea) and tap water. The main component of creamer is hydrogenated vegetable oil, which is a trans fatty acid. Trans fatty acids will reduce the secretion of male hormones, have a negative impact on sperm activity, and interrupt the reaction process of sperm in the body.
