LONDON (Reuters) - People who drink three to four cups of coffee a day are more likely to see health benefits than harm, experiencing lower risks of premature death and heart disease than those who abstain, scientists said on Wednesday.
The research, which collated evidence from more than 200 previous studies, also found coffee consumption was linked to lower risks of diabetes, liver disease, dementia and some cancers.
Three or four cups a day confer the greatest benefit, the scientists said, except for women who are pregnant or who have a higher risk of suffering fractures.
