Caffeine and estrogen levels

Caffeine could lead to changes in estrogen levels, but it depends on your ethnicity.

The study found caffeine affects white and Asian women differently.

Drinking about two cups of coffee a day increased estrogen levels in Asian women.

The same amount of caffeine lowered estrogen levels for white women.

The effects on black women were inconclusive.

Researchers stress caffeine doesn’t seem to cause problems in the short term, or affect ovulation.

But in the long term, caffeine can change estrogen levels, which play a role in osteoporosis, and some cancers.
