Caffeine can disrupt glucose metabolism and contribute to
the development and poor ability to control type-2 diabetes, say US researchers
from the Duke University. Caffeine has a potential for raising insulin
resistance or impaired glucose tolerance in adults without diabetes which
pre-disposes them for developing diabetes.
It has also been proved that consumption of caffeinated beverages, especially coffee raise the blood glucose levels among patients with type 2 diabetes. This could compromise with the treatment that is aimed at controlling diabetes.
