Scientists have found that the systematic consumption of caffeine can cause a change in the level of estrogen - a particularly important female hormone. This study was conducted by experts from the Eunice Kennedy Shriver National Institute for Human Development and Child Health. The results of the studies showed that women from Asian countries who drank 2 cups of coffee daily had higher levels of the above hormone..

Representatives of the European continent, who consumed the same amount of caffeine per day, had estrogen levels several times lower. At the same time, scientists took into account not only the caffeine that entered the body of women directly from coffee, but also from other products (green and black tea, as well as caffeine-containing sparkling water), writes The Times of India..

Animal studies suggest that caffeine may affect ovulation. In order to verify this theory, in the period 2005-2007, scientists examined about 250 or more women in the age category from 18 to 44 years..

Experimenter Enrique Schisterman explains:.

“Consumption of caffeinated beverages among women of reproductive age does indeed affect estrogen levels.. But these fluctuations did not have a serious effect on ovulation itself..

But it is known for sure that estrogen plays an important role in terms of female cycles, and imbalance of estrogen can cause a number of diseases: osteoporosis, endometriosis, endometrial cancer, as well as ovarian and breast cancer..
