▲ pregnant drink coffee to give birth to a black baby? Su Yining took the mirror and let her "look at herself".

Does drinking coffee during pregnancy really affect your baby's skin color? Su Yining, a famous obstetrician and gynecologist, wrote on Facebook that one day in the clinic, a mother sadly asked if she ate too much soy sauce and coffee during pregnancy to give birth to a dark-skinned baby. And was read by my mother-in-law because of this. After hearing the question, Su Yining directly asked her to look in the mirror and let her know that "genetic inheritance is very scary."

"are you and your husband white? Obviously, I have to use a flashlight to find you two. " Su Yining wrote that now there are frequent rumors on the Internet that as long as all colored food is shot, "will white people become black babies after drinking coffee all their lives?" Do Nigerian aborigines turn white when they drink milk every day? " He said that food is food, just the right amount, but with some very inexplicable reasons to encourage pregnant women not to eat anything, "this is really strange."

Is it true that you can't drink coffee during pregnancy? In fact, it's okay to drink 1 or 2 cups a day.

In fact, as early as the end of August, Su Yining analyzed the impact of drinking coffee on pregnant women on Facebook. It is mentioned that in 2000, the New England Magazine analyzed more than 500 pregnant women who had spontaneous abortion and 1000 pregnant women who did not have spontaneous abortion, and found that the higher the dose of coffee, the higher the risk of miscarriage, from an average of 20% to 26%. But the intake is too high may reach 30%, the increase is not large.

As for some pregnant mothers' concern, caffeine will cause "low weight" of the fetus, but the data show that the average intake of 100mg caffeine increases the risk of low weight by 13%. "about 100 people who drink coffee will become underweight," but the difference will be greater only if they drink more, so it is no problem to drink 1 cup or 2 cups a day.

With regard to the fact that drinking coffee will give birth to a "black-fleshed child", Yang Zhixiong, a dermatologist at Gengxin Hospital, wrote in 2012 that the whiteness or blackness of the skin of ordinary people depends on their congenital genetics, and the amount of melanin in the fetal skin has been determined when the parents are genetically paired. When there are more melanocytes in the skin, the skin will be darker; on the contrary, the skin will be white, which has nothing to do with the food consumed during pregnancy.
