Tony Cenicola/The New York TimesCan a dose of caffeine affect estrogen levels?
Your daily dose of caffeine may tinker with more than just your energy levels.
A new study of women ages 18 to 44 found that drinking coffee and other caffeinated beverages can alter levels of estrogen. But the impact varies by race. In white women, for example, coffee appears to lower estrogen, while in Asian women it has the reverse effect, raising levels of the hormone.
The study did not look at older women, but women of child-bearing age who enjoy a daily cuppa have little reason to fret, the researchers said.
