A report in the journal Diabetes Care looks at the effects of caffeine consumption on patients with diabetes. I found the article on this here.
It looks at more evidence on just how powerful a drug caffeine can be. Researchers tested a small group of people over 72 hours with a continuous blood sugar monitoring device implanted subcutaneously.
After giving the subjects a dose of caffeine equal to four cups of coffee, they watched blood sugar levels throughout the day. An average increase in blood sugar of 8 percent was noted with peak increases noted just after meals.
Authors caution that they have no explanation for how caffeine directly affects blood sugar but wonder if it may have something to do with increased adrenaline release or perhaps a chemical inhibitory effect on glucose uptake by the body’s cells.
