It was found that the effect of both caffeinated and decaffeinated coffee on the risk of type 2 diabetes is above average Follow-up time 24 years detected. A subset of participants also had important biomarkers of glucose metabolism measured.

Only caffeinated coffee reduced the risk

Totally sick 979 participants type 2 diabetes with consumption caffeinated coffee was inversely associated with disease risk, researchers report.

As consumption increased, the risk decreased and more than four cups caffeinated coffee daily, according to experts, the likelihood of developing diabetes is reduced 54 percent less than if you don’t drink coffee at all. However, no significant effect was found for decaffeinated coffee.

Substitution analysis also showed that replacing one sugar-sweetened beverage per day with caffeinated coffee 17 percent lower risk of type 2 diabetes, the research team said.

Higher consumption of caffeinated coffee was also associated with lower levels in the subgroup Fasting insulin and C-peptide concentrations and consumption of decaffeinated coffee also reduced C-peptide concentrations.

The underlying mechanism is unclear

According to the results of the study, caffeinated coffee could High-risk population how women with a history of gestational diabetes contribute to reducing the risk of type 2 diabetes and improving the metabolic profile.

However, the exact mechanism of the association remains unclear. Further studies must prove whether components other than caffeine also play a significant role. (fp)
