One more cup of coffee a day could cut your risk of Type 2 diabetes
Researchers from Harvard University found that people who increased their coffee consumption by at least one cup per day over a period of years were 11% less likely to get Type 2 diabetes compared with people whose coffee-drinking habits didn't change.
On the flip side, people who dialed back their coffee habit by at least one cup a day were 17% more likely to develop Type 2 diabetes.
"Coffee is pretty fascinating," said Shilpa Bhupathiraju, a nutritional epidemiologist at the Harvard School of Public Health and the lead author of the paper. "It seems to be associated with a lower risk for many chronic diseases."
The findings in this study are based on statistical analysis of three long-term and large-scale studies that tracked the diet, lifestyle and medical conditions of more than 120,000 medical professionals over the course of 20 years.
Previous work has shown that chemical compounds in coffee, not the caffeine, are likely responsible for the association between coffee drinking and lower risk of Type 2 diabetes.
"We know that phenolic compounds in coffee improves glucose metabolism in animal models," Bhupathiraju said. "Coffee is also a really good source of magnesium, which has been associated with a lower risk of Type 2 diabetes."
If that is the case, drinking more uncaffeinated coffee should be just as effective as drinking more caffeinated coffee in lowering the risk of Type 2 diabetes. In this study, the researchers found that changes in decaffeinated coffee consumption had no statistical effect on risk. That may be because not enough participants made a major chan Continue reading
