Title Caffeine may affect women's health
Description A daily intake of caffeine can have other effects than just increasing energy. A new study found that drinking coffee or other caffeinated beverages may affect young female estrogen levels may go down or rise. The effects of caffeinated beverages may vary by race. In white women, for example coffee can lower estrogen. While in Asian women coffee has the opposite effect, increase the levels of these hormones. "This study does not examine older women, but women of childbearing age who regularly consume a cup of tea every day.They consume tea every day on a regular basis and without the slightest worry," the researchers said. The effects of caffeine on estrogen levels are minimal in healthy women, and have no effect on ovulation or overall health, at least in the short term. "This research is quite important physiologically because it helps understand how caffeine is metabolized by different genetic groups, but for women of reproductive age, drinking coffee will not significantly alter clinical hormonal function," said Dr. Enrique Schisterman, a senior researcher from the National Institutes Of Health as reported from TheNewYorkTimes, Monday (30/1/2012). The study has analyzed data on more than 250 women who were checked 1-3 times a week for two menstrual cycles. The study participants gave blood samples along with details of behaviors such as exercise, eating, and smoking. On average, they consume about 90 mg of caffeine a day, equivalent to about one cup of coffee. After controlling for a number of variables, such as age and diet, the researchers found that among Asian women who consumed 200 mg or more of caffeine a day had higher levels of estrogen than those who consumed less than that amount. A similar pattern is seen among black women, although not statistically significant. However, in white women of 200 mg or more of caffeine it has a slight downward effect on estrogen levels. About 90 percent of women between the ages of 18-34 years consume caffeine drinks equivalent to 1-2 cups of coffee every day. "The reason why caffeine has a different impact on different races is not known clearly, but the possibility of genetics has an influence on caffeine metabolism.Colourine sources also seem to make a difference.Chers have examined caffeine from beverages other than coffee, such as green tea and soda and Is associated with higher estrogen in all women, regardless of race.A variety of levels of antioxidants and other compounds in beverages, as well as additives such as milk and sugar, may also play a role, "said Dr. Schisterman. For a while, healthy premenopausal women do not have to worry about caffeine intake in the short term. Further research is still needed to see if there may be cumulative impacts for years or decades. The results of the study have been published in The American Journal of Clinical Nutrition. visit quick weight loss program
