Coffee makes your breasts shrink.

We all know that caffeinated drinks can keep people awake, and there are many women who drink coffee to suppress appetite and achieve weight loss. But a new finding by Swedish scientists has attracted a lot of attention because they point out that girls who drink more than three cups of coffee a day will have smaller breasts.

Cancer researchers have found that half of women have a gene that causes their breasts to shrink when they ingest caffeine.

Nearly 300 women were tested in the study, but Helena Kingslom of Lund University said women should not be alarmed by the results.

"Coffee drinkers don't have to worry about their breasts shrinking overnight," she explains. The breasts will get smaller, but they won't disappear completely. If anyone tries to judge who drinks coffee based on a woman's bra size, he'll end up disappointed. Bras come in two size, one cup size and the other bra circumference, so it's hard to tell which women drink coffee based on the bra."

While caffeine may shrink women's breasts, men who drink coffee have the opposite effect, with their "breasts" enlarged. The study also found that caffeine has a beneficial side, helping to reduce a woman's risk of breast cancer.
