Reason for Blood Sugar Rise : caffeine

Your glucose can ascend after
you consume coffee – even dark
ones
without any calories because of

the caffeine in it.
Other foods in the same
categories of caffeine content
like coffee are
dark tea, green tea, and
caffeinated drinks.
Every individual with
diabetes responds to
sustenances and drinks in an
unexpected way, so
it's best to monitor your own
reactions.
However, it must be noted that
other contents in coffee might
offer assistance
to prevent diabetes in
healthy individuals with no
diabetes.
