Increasing Coffee Consumption Protects Against Type 2 Diabetes
The first study to examine whether a change in the amount of tea or coffee consumed has any effect on the subsequent risk for type 2 diabetes among healthy individuals has found that it does, at least for coffee. And the effects become apparent within a relatively short period of time, 4 years.
In this new observational analysis of 3 large US cohorts, those who increased their intake by around one-and-a-half cups of regular coffee per day, on average, had an 11% lower risk for type 2 diabetes over the following 4 years, compared with people who did not alter the amount of coffee they drank, report Shilpa N. Bhupathiraju, PhD, department of nutrition, Harvard Public School of Health, Boston, Massachusetts, and colleagues in the study, published online April 24 in Diabetologia.
And conversely, those who reduced the amount of coffee drunk by a median of 2 cups per day had a 17% higher risk for type 2 diabetes during the next 4 years, relative to those who didn’t change their coffee habit.
Changes in tea consumption were not associated with type 2 diabetes risk, possibly because not that many people drank tea or changed the amount of tea they drank,
