Caffeinated and decaffeinated coffee consumption and risk of type 2 diabetes: a systematic review and dose-response meta-analysis.

High consumption of caffeinated or decaffeinated coffee may reduce type 2 diabetes risk.

The objective of this research work was to determine the correlation between the consumption of caffeinated and decaffeinated coffee and the incidence of type 2 diabetes. Researchers analyzed data obtained from 28 studies that examined 1,109,272 subjects and 45,335 type 2 diabetes cases. They found out that subjects who drank between 1-6 cups of caffeinated or decaffeinated coffee per day had slim chances of developing type 2 diabetes. The findings of this review reveal that high intake of caffeinated or decaffeinated coffee may decrease an individual's susceptibility to the development of type 2 diabetes.

Note: This is another study that seems to indicate that caffeine does not promote diabetes. Although other studies do indicate that caffeine makes it harder to keep blood sugar under control.
