Do women's breasts really get smaller after drinking coffee every day?

Do women's breasts really get smaller after drinking more than three cups of coffee a day?

Recently, a new discovery by Swedish scientists became popular on Weibo and reposted nearly a thousand times. Weibo pointed out that if girls drink more than three cups of coffee a day, their breasts will become smaller. Oncology researchers have found through testing that half of women contain a special gene that causes their breasts to shrink when they consume caffeine and can effectively prevent breast cancer. Is this the case? Yesterday, experts on genes and breast said that because there are metabolic genes in the human body, the body absorbs and metabolizes caffeine at different speeds, resulting in different metabolic reactions, which may lead to shrinkage of the chest circumference, but it has nothing to do with the amount of coffee drunk every day., and drinking coffee every day increases the risk of breast cancer.

The study tested nearly 300 women. But Helena Kinthrom of Lund University said women do not need to worry about the results all day long.

She explained that women who drink coffee don't have to worry about their breasts shrinking overnight. Although the breasts will become smaller, they will not disappear completely. Anyone who wants to judge who drinks coffee based on a woman's bra size will ultimately be disappointed. Bras come in two size, one is the cup size and the other is the circumference of the bra, making it difficult to tell which women drink coffee based on the bra.

Conversely, while caffeine may shrink a woman's breasts, men who drink coffee have another result, and their "breasts" will expand. Studies also found that caffeine also has a beneficial side, helping reduce a woman's risk of developing breast cancer.

A review of the original text found that the study was published in the British Journal of Cancer. Different from the original Weibo text, the related paper published by researchers at Lund University in Sweden actually mentioned two important CYP1A2 * 1F genes. With them, coffee intake and chest size have different effects.

The paper mentioned that between 1996 and 2006, researchers surveyed the living habits of 269 healthy women, tested the CYP1A2 * 1F gene type, and collected data on their chest size to conduct statistical analysis. It was found that girls with the CYP1A2 * 1F C-allele gene had smaller breasts than girls who drank less coffee every day; while subjects with the CYP1A2 * 1F A/A gene had almost no correlation between the amount of coffee consumed and the size of the breasts.

"Such surveys only found that the coffee intake of some people showed a correlation with chest size. It doesn't mean that drinking 3 cups of coffee a day can cause chest shrinkage." Experts believe that according to the conclusions of the original Weibo text, three groups of controlled experiments are needed: one group of people drank 3 cups of coffee a day, one group of people drank 1 cup of coffee a day, and one group of people drank nothing. In addition, the three groups of people were also required to have exactly the same diet and lifestyle. These experimental contents are not mentioned at all in relevant papers, so this research is not reliable.

Drinking coffee every day may make your chest shrink

"Our body does have genes that control breast size, such as height, weight, appearance, and physical characteristics, which are all formed by the participation of multiple genes." An expert who specializes in working with genes said that although he has never heard of rumors that coffee may cause breast reduction, the CYP1A2 * 1F gene mentioned in the British Journal of Cancer paper is a large family with many branch members and are related to human metabolic information. For example, the metabolic progress of the food and drugs that everyone eats can be rapid and slow through the liver and kidneys, and can even differ by more than 300 times. These genes are all controlled.

"For example, if some people eat the same food or medicine, taking a regular dose is useless. It takes many times that of ordinary people to be effective. For some people, just the opposite is true. Eating a little bit will have a great reaction. This is the magic of this kind of gene." Experts infer that drinking coffee every day may shrink the chest circumference. That is because the body may absorb and metabolize caffeine at different speeds. Under certain pathological conditions of the body, it may cause different metabolic reactions, resulting in smaller breasts.

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

Women whose breasts are too plump and feel that they are overloaded can try drinking coffee to improve, because experts infer that coffee can help reduce the size of the chest to a certain extent. A study published by the Canadian Women's Health Center pointed out that if women drank 3 cups of coffee a day, the incidence of breast cancer would be reduced by 25% to 70%, even for women with a family history of breast cancer.

Experts told the editor the opposite answer: "Epidemiological surveys abroad have confirmed that long-term drinking of coffee and red wine increases the risk of breast cancer."

Experts say that foods such as chocolate and coffee that contain cocoa have an exciting effect and will stimulate increased pituitary secretion when eaten. Eating every day will increase the risk of cancer.

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

"The chest circumference is too large. One is that the breast itself is large, and the other is that the breast is sagging because of loose ligaments. Generally, cups above D are considered too large, and nipples exceed 4 centimeters below the fold of the breast are considered drooping. If the breasts are really too big, you can take drugs to inhibit breast hyperplasia. But some people actually have a lot of fat and not many glands in their breasts. These people have better effects on losing weight and thinning their breasts through exercise. For people with drooping breasts, they can also undergo drooping suspension surgery for plastic surgery."

Experts say that if you want to keep your breasts healthy, it is best to eat vegetarian foods, because many meats may contain hormones in feed, which can easily cause breast cancer. In addition, it is best not to touch health care products.

"The ovaries of ginseng, bird's nest, and Hashimoto tree frog all contain estrogen. Long-term consumption is not good for the breasts." Experts say that in addition, plasticizers are also a major killer to 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. The plasticizer is easy to release and it will definitely be bad for breasts if eaten.
