For one factor, the info can’t say whether or not rising coffee consumption would help to protect well being, Kao stated.
“In other words, although women who drink 3 cups of coffee/day might have better long-term functioning than non-coffee drinkers, we don’t know if non-coffee drinkers started drinking 3 cups a day, whether they would have better functioning than if they remained non-coffee drinkers,” he stated in an electronic mail.
