They had male volunteers drink caffeinated and decaffeinated coffee one hour before they ate cereals with low or moderate levels of sugar, United Press International reported.
Among those who ate the low-sugar cereal, blood sugar levels jumped 250 percent higher after they had caffeinated coffee, compared to when they had decaffeinated coffee. The study was published in the American Journal of Clinical Nutrition.
"Caffeine interferes with our body's response to insulin. It makes us resistant to insulin which in turn makes our blood-sugar levels go higher," said researcher Terry Graham, UPI reported.
People at risk for type 2 diabetes should be cautious and consider drinking decaffeinated coffee, Graham suggested. – (HealthDay News, May 2008)
