Cutting Caffeine May Help Control Diabetes: "Daily consumption of caffeine in coffee, tea or soft drinks increases blood sugar levels for people with type 2 diabetes and may undermine efforts to control their disease, say scientists at Duke University Medical Center.
The researchers found that when the participants consumed caffeine, their average daily sugar levels went up 8 per cent. Caffeine also exaggerated the rise in glucose after meals: increasing by 9 percent after breakfast, 15 percent after lunch and 26 per cent after dinner.
"We're not sure what it is about caffeine that drives glucose levels up, but we have a couple of theories," says Lane, who is the lead author of the study. "It could be that caffeine interferes with the process that moves glucose from the blood and into muscle and other cells in the body where it is used for fuel. It may also be that caffeine triggers the release of adrenaline -- the 'fight or flight" hormone that we know can also boost sugar levels."
Either way, he says, the higher sugar levels that result from caffeine are bad news for diabetic patients."
