Introduction: Recently, a new discovery made by Swedish scientists has been widely circulated in Weibo and forwarded nearly a thousand times. Weibo pointed out that if girls drink more than three cups of coffee every day, their * * * will become smaller. Is this the case?

Can you shrink your breasts after drinking three cups of coffee?

Nearly 3 women were tested in this study. But Helena Kinslow of Lund University said that women don't have to worry about this research all day.

She explained that women who drink coffee don't have to worry that their * * * will get smaller overnight. * * * Although it will become smaller, it will not disappear completely. If anyone wants to judge who drinks coffee according to the size of a woman's bra, he will be disappointed in the end. Bras have two sizes, one is the size of a cup, and the other is the circumference of a bra, so it is difficult to tell which women drink coffee according to a bra.

On the contrary, although caffeine may make women's * * * shrink, men who drink coffee will have another result, and their * * * will increase. The study also found that caffeine also has a beneficial side, which helps to reduce the risk of breast cancer in women.

According to the original text, this study was published in the British Journal of Cancer. Different from Weibo's original text, two important CYP1A2*1F genes are actually mentioned in the relevant papers published by researchers from Lund University in Sweden. With them, coffee intake and chest size have different effects.

It is mentioned in the paper that from 1996 to 26, the researchers investigated the living habits of 269 healthy women, detected the CYP1A2*1F gene types, and collected data on their chest sizes, and made statistical analysis on these data. It was found that the girls who drank a lot of coffee every day were * * * smaller than the girls who drank less coffee. However, the amount of coffee consumed by the subjects with CYP1A2*1F A/A gene has little to do with the size of * * *.

"As a result of this investigation and study, only a part of people's coffee intake is found, which shows a correlation with chest size. It doesn't mean that drinking 3 cups of coffee a day can cause the chest to shrink. " Experts believe that according to the conclusion of Weibo's original text, three groups of controlled experiments are needed: one group drinks three cups of coffee a day, one group drinks one cup of coffee a day, and one group drinks nothing. In addition, these three groups of people are required to have the same diet and life schedule. These experimental contents are not mentioned at all in related papers, so this study is not reliable.

Drinking coffee every day may shrink the bust

"There are indeed genes that control the size of * * * in our body, such as height, weight, appearance and physical characteristics, which are all formed by multiple genes." An expert who specializes in dealing with genes said that although I have never heard of the rumor that coffee may cause breast contraction, the CYP1A2*1F gene mentioned in the British Cancer Journal is a big family with many branches, which is closely related to human metabolism. For example, the food and drugs that everyone eats pass through the liver and kidney, and the metabolic progress is fast or slow, even more than 3 times different, which is controlled by such genes.

"If some people eat the same food or medicine, it's useless to eat the conventional dose, but it's effective to eat many times as much as ordinary people, while others, on the contrary, have a great reaction if they eat a little, which is the magic of this kind of gene." Experts infer that drinking coffee every day may shrink the bust, because the body may have different absorption and metabolism rates of caffeine, which may cause different metabolic reactions under certain pathological conditions of the body, leading to smaller breasts.

Does drinking coffee every day increase the risk of breast cancer?

Women who feel that their breasts are too full and their chests are overloaded can try to improve by drinking coffee, because experts infer that coffee can help reduce the size of their breasts to a certain extent. A study published by the Canadian Women's Health Center pointed out that if women can drink three cups of coffee a day, the incidence of breast cancer will be reduced by 25% to 7%, even for women with a family history of breast cancer.

Experts told me the opposite answer: "Foreign epidemiological surveys have confirmed that drinking coffee and red wine for a long time will increase the risk of breast cancer."

Experts say that foods containing cocoa, such as chocolate and coffee, have an exciting effect, which will increase pituitary secretion if eaten. Eating it every day will increase the risk of cancer.

Of course, he also mentioned that only foreigners drink a lot of coffee every day. In terms of eating habits, drinking coffee is not the main habit of Chinese people.

"The chest circumference is too large, one is that * * * itself is large, and the other is that the ligament is slack and drooping. Generally, a cup above D is too large, and a fold below * * * exceeds * * by 4 cm. * * * is really too big, you can take drugs to inhibit mammary gland hyperplasia. But some people actually have a lot of fat, and there are not many glands. It is better for such people to lose weight and lose weight through exercise. For people with drooping, you can also do drooping and hanging surgery to shape. "

Experts say that to keep healthy, it is best to eat a vegetarian diet, because many meats may contain hormones in the feed, which may easily cause breast cancer. In addition, it is best not to touch health care products.

"Ginseng, bird's nest and hashish membrane (the ovary of tree frog) all contain estrogen, which is not good for * * * if eaten for a long time." Experts say that in addition, plasticizers are also a big killer for women. Many people are used to putting a box of mineral water in the trunk of their cars, but now the bottles are getting thinner and thinner, and the plasticizers are easily released. Eating them will definitely be bad for * * *.
