There have been several studies on coffee and
diabetes. These studies investigated how coffee affects the risk of developing
type 2 diabetes,
as well as how coffee affects people who already have the disease.

While more research needs to be done before any recommendations can be made
about how coffee affects diabetes (or the risk of diabetes),
the results of the studies are interesting.
Several studies (see one here)
suggests that participants who drank caffeinated coffee
lowered their risk of getting diabetes, when compared with
study participants who did not drink coffee. The participants with the
lowest risk were the ones who drank the most caffeinated coffee.
Some participants also drank decaffeinated coffee but there were too
few of them for researchers to make any conclusions.
Researchers don't know what ingredient in coffee is offering protection
against diabetes. Caffeine is not believed to
be the protective ingredient, but rather the chemicals in coffee appear to
have protective qualities.
A small study
was conducted on people who have already developed diabetes.
It was found that diabetics who drank caffeinated coffee experienced
significant rises in blood glucose levels -- to the point where the caffeine
raises blood sugar as much as insulin or diabetes medications lowers it.
Drinking caffeinated coffee (or any other beverage with caffeine) may make
it harder for diabetics to control their blood glucose levels.
People react differently to caffeine. Researchers suggest that diabetics
who want to control their blood sugar levels better, try switching to
decaffeinated coffee or giving up coffee for a while to see if it makes
a difference. Some people will notice a change while others may not.
Studies were based on drinking black coffee with cream and sugar.
Fancy, sugary, specialty coffee drinks aren't included.
