How women can drink coffee healthily

　　[Weibo introduction]

　　@Hangzhou healthy #drink coffee Can reduce breasts #Recently, a new discovery by a Swedish scientist has been widely circulated on Weibo, and has been forwarded nearly a thousand times. Weibo points out that if girls drink more than three cups of coffee a day, their breasts will become smaller. Cancer researchers have discovered through testing that half of female There is a special gene in the body. Because of this gene, when they consume caffeine, their breasts will shrink, and it can also effectively prevent breast cancer . Is this the case? Yesterday, the reporter asked an expert on genes and breast cancer. He said that because there are metabolic genes in the human body, the body absorbs and metabolizes caffeine at different rates, resulting in different metabolic reactions. It may cause breast circumference to shrink, but it has nothing to do with the amount of coffee drank every day, and drinking coffee every day will increase the risk of breast cancer.

　　It’s unreliable that drinking three cups of coffee can reduce breast size

　　The study examined nearly 300 women. But Helena Kinslom from Lund University said there was no need for women to be alarmed by the findings.

　　Women who drink coffee don't have to worry about their breasts getting smaller overnight, she explains. Although the breasts will become smaller, they will not completely disappear. Anyone who tries to judge which women drink coffee based on their bra size is going to be disappointed. Bras come in two sizes, cup size and bra girth, so it's hard to tell which women drink coffee based on their bras.

　　Conversely, while caffeine may cause women's breasts to shrink, coffee drinkers male But another result will occur, their "breasts" will increase. Studies have also found that caffeine also has a beneficial side, helping to reduce the risk of breast cancer in women.

　　After checking the original text, I found that this study was published in the British cancer Magazine. Different from the original Weibo article, the related paper published by the research institute of Lund University researchers in Sweden actually mentioned two very important CYP1A2*1F genes. With them, coffee intake and breast size have different effects.

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

　　“Such surveys only found a correlation between coffee intake and breast size for some people. It does not mean that drinking 3 cups of coffee a day will cause breast reduction. ”Qi Ming, director of the Genetics Department of the First Hospital of Zhejiang Medical University, believes that according to the conclusion of the original Weibo article, three groups of controlled experiments need to be conducted: one group of people drinks three cups of coffee a day, one group of people drinks one cup of coffee a day, and one group of people drinks nothing. In addition, the three groups of people are also required to have the same diet and daily routine. These experimental contents are not mentioned at all in the relevant papers, so this research is not reliable.

　　Drinking coffee every day may shrink your bust

　　“Our bodies do have genes that control breast size, such as height, weight, appearance, and physical characteristics, which are all formed by the participation of multiple genes. ”Qi Ming, director of the Genetics Department of the First Hospital of Zhejiang Medical University, specializes in dealing with genes. I haven't heard of any rumors that coffee can cause breast reduction. But he told me that the CYP1A2*1F gene mentioned in the British Journal of Cancer paper is a large family with many branch members and is closely related to human metabolism. For example, the food and medicines consumed by each person pass through the liver and kidneys, and the metabolism rate may be fast or slow, and may even differ by more than 300 times. These genes are all controlled by these genes.

　　“For example, if some people take the same food or medicine, it will be useless to take the regular dose. It will take many times the amount of ordinary people to be effective. Some people are just the opposite. They will have a big reaction if they take a little bit. This is the magic of this type of gene. ”Qi Ming deduced that drinking coffee every day may cause breast circumference to shrink. This is because the body may absorb and metabolize caffeine at different rates. Under certain pathological conditions of the body, different metabolic reactions may occur, resulting in smaller mammary glands.

　　Drinking coffee every day increases risk of breast cancer

　　Women who have overly plump breasts and feel that their chests are overloaded can try drinking coffee to improve it, because experts infer that coffee can help reduce breast size 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 70%, even for women with a family history of breast cancer.

　　In the city Hospital Xu Haibin, director of breast surgery, told reporters the opposite answer: "Foreign epidemiological surveys have confirmed that long-term consumption of coffee and red wine will increase the risk of breast cancer. ”

　　Xu Haibin said that foods containing cocoa, such as chocolate and coffee, have a stimulating effect, and eating them will stimulate the pituitary gland to increase secretion. Eating it every day increases 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 Chinese people.

　　If you want to keep your breasts healthy, you should eat less ginseng, bird’s nest, and hash browns.

　　During the interview, it was found that many women were worried about their too-large busts. Regarding this issue, the reporter specifically asked Yang Oou, the city's chief breast surgeon.

　　“Bust circumference is too large, one is that the breasts themselves are large, and the other is breast sagging due to loose ligaments. Generally speaking, a cup cup above D is considered too large, and a nipple that is 4 centimeters beyond the inframammary fold is considered saggy. The breasts are really too big, you can take some medicine to suppress them Breast hyperplasia of drugs. But some people actually have a lot of fat and don't have many glands in their breasts. These people have better results in losing weight through exercise. For people with sagging breasts, sagging surgery can also be performed to reshape the breasts. ”

　　Yang Oou said that if you want to keep your breasts healthy, it's best to eat a vegetarian diet, because a lot of meat may contain hormones in feed, which can easily cause breast cancer. In addition, it is best not to touch health products.

　　“Ginseng, bird's nest, and hash brown (tree frog's ovary) all contain estrogen, and long-term consumption is not good for breasts. ”Yang Oou said 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 car, but now the bottles are getting thinner and thinner. Plasticizers are easily released, and eating them is definitely not good for breasts.
