Caffeine is found in coffee, most non-herbal teas, most soft drinks and new energy drinks.
Researchers at Duke Medical Center in North Carolina found that caffeine interferes with blood sugar control, they found a strong correlation between caffeine intake at mealtime and increased glucose and insulin levels among people with type 2 diabetes.
Type 2 diabetes is a chronic disease with severe complications such as neuropathies, blindness, renal failure, amputations, stroke, heart disease and premature death.
However other studies show that drinking coffee as little as one cup of coffee daily reduced the risk of type 2 diabetes by 60 percent compared to people who never drank coffee.
This applied both to people with normal blood sugar as well as those with pre-diabetes. A study by Harvard researchers has found that those who are not diabetic who regularly drank coffee over the long term significantly reduced the risk of onset type 2 diabetes, compared to non-coffee participants.
The caution is that caffeine beverages can spike blood sugar for about thirty minutes after consuming them.
In 2008 study published in Diabetes Care, researchers found that caffeine consumption exaggerated the rise in the blood sugar after meals: by 9 percent after breakfast, 15 percent after lunch and 26 percent after dinner.
