Cutting out tea and coffee could help diabetics cope with their disease, a study suggests.
Researchers have shown that a daily dose of caffeine raises blood sugar levels by 8 per cent, undermining the effects of drug treatment.
The U.S. findings back up a growing body of research suggesting that eliminating caffeine might be a good way to help manage type 2 diabetes, which usually develops in middle age.
James Lane, who led the study at Duke University, North Carolina, said: "Coffee is such a common drink in our society that we forget that it contains a very powerful drug - caffeine.
Our study suggests that one way to lower blood sugar is to simply quit drinking coffee, or other caffeinated beverages. It may not be easy, but it doesn't cost a dime and there are no side effects."
His team studied the blood sugar, or glucose, levels in ten diabetics who drank at least two cups of coffee a day. When the patients had a caffeine fix, their average daily blood sugar levels were seen to rise by 8 per cent. Caffeine - which is found in tea, coffee and some fizzy drinks - also exaggerated the rise in glucose after meals.
