Type-2 diabetics who are coffee drinkers may find it tougher to
control their blood sugar, a new study released Wednesday said.
Researchers at Duke University Medical Center in Durham studied
the effects of caffeine in 10 patients with Type-2 diabetes by
implanting small glucose detection devices under their abdominal
skin to track the rise and fall of patients' blood sugar
levels.
The participants were given four tablets containing caffeine
equivalent to four cups of coffee and identical placebo pills on
various days. The study found their daily blood sugar levels went
up by 8 percent when they took tablets containing caffeine. It rose
even higher, up to 26 percent after they had dinner.
"Caffeine appears to disrupt glucose metabolism in a way that
could be harmful to people with Type-2 diabetes," said James Lane
who led the study.
"This suggests that people with diabetes might want to avoid
coffee and other caffeinated beverages," Lane said.
Caffeine is found in coffee, tea and many soft drinks. However,
this finding is somewhat confusing, as previous study indicated
that people who drank coffee had a reduced risk of Type-2 diabetes,
and those who drank the most coffee had the lowest risk.
U.S. researchers reported last Monday that too much caffeine
during pregnancy raises the risk for miscarriage. And another study
showed that caffeine may lower a woman's chances of developing
ovarian cancer.
