Do you really shrink your breasts by drinking coffee often?

Q: will drinking coffee really shrink your breasts?

A: this statement is actually a misreading of the results of a scientific study, and there is no clear evidence that drinking coffee often leads to chest reduction.

As early as a few years ago, the author read such a report: "A new discovery by Swedish scientists has attracted a lot of attention because they pointed out that if girls drink more than three cups of coffee a day, their breasts will become smaller!" The author's first reaction to this report was that it must not be true. How could any scientist study the relationship between breast size and coffee intake, but after looking up the data, it was found that the study did exist.

Although the study does exist, is it credible? As a matter of fact, when the media reported on this study by researchers at Lund University University in Sweden, they were suspected of taking it out of context and severely "headline party." The important paper published in the British Journal of Cancer on the different effects of the two CYP1A2*1F genes on the relationship between coffee intake and chest size was omitted. The researchers analyzed the data statistically by investigating the living habits of 269 healthy women, testing the CYP1A2*1F gene type, and collecting data on the size of their breasts. It was found that girls who drank a lot of coffee every day had smaller breasts than those who drank less coffee, while those with the CYP1A2*1F C-allele gene had little to do with breast size, while those with the CYP1A2*1F A gene had little correlation with breast size. The results of such a study only found a correlation between coffee intake and chest size in some people, which does not mean that drinking coffee leads to small breasts, nor does it mean that drinking coffee will further lead to smaller breasts. Just like we found that the sun rises after the rooster crows, but in fact it is not because of the rooster crow that causes the sun to rise.

Whatever the significance of the study, the conclusion will not be that "if girls drink more than three cups of coffee a day, their breasts will get smaller." Such a statement misleads people into thinking that if you continue to drink three cups of coffee a day, your breasts will slowly get smaller. To come to such a conclusion, an experiment is needed: one group drank three cups of coffee a day, one group drank one cup of coffee a day, and one group drank nothing. In addition, the three groups were required to have exactly the same diet and daily routine. After a while, see if there is any change in the size of their breasts, whether they are bigger or smaller. In other words, after excluding all other factors, examine the effect of coffee and the amount of coffee consumed on the same person's chest changes.

Therefore, the saying that "drinking coffee often shrinks your breasts" is another misreading of the results of scientific research. at present, there is no clear evidence that "if girls drink more than three cups of coffee a day, their breasts will become smaller." so girls who love coffee should, as always, drink it at ease.
