According to an umbrella review (a collective review of analyses from previous studies) led by University of Southampton's public health specialist Robin Poole, drinking three or four cups of coffee a day may very well be linked to lowered risks of liver disease, type 2 diabetes, dementia, gallstones, gout, and certain cancers such as endometrial, skin, liver, and prostate cancer.
People who drank coffee versus non-coffee drinkers were also consistently seen to have a lower risk of death from heart disease.
“Coffee drinking appears safe within usual patterns of consumption,” said Poole in an article that was published in the BMJ British medical journal.
Before you chug that next cup of coffee, make sure you're not pregnant, of course.
Poole noted that their findings were mostly based on observational data, and not on actual cause and effect.
