Coffee consumption is associated with a reduced risk of type 2 diabetes, new study confirms a Franco-Brazilian published in the American Journal of Clinical Nutrition.

Sartorelli Daniela S Guy Fagherazzi and colleagues studied the long-term effect of coffee, tea and chicory on the risk of type 2 diabetes by analyzing data from a study involving 69.532 French aged 41-72 from which follow-up was made 11 years later on average.

Diabetes risk was reduced by a quarter among participants who were taking three or more cups of coffee per day compared to those who did not. When the consumption of 1 cup per day or more was compared to no consumption, only the consumption accompanying lunch was related to reduced risk of developing the disease. This link was present for the regular and decaffeinated coffees as well as for filtered coffee (not instant) and black.

These results suggest that when the coffee is consumed plays a distinct role in the metabolism of glucose, the researchers conclude. They also suggest that the beneficial effect is due to a substance other than caffeine.

Neither tea nor chicory were associated with a reduced risk of diabetes in this study.

Take one cup of coffee a day, regular or decaffeinated, was associated with a 30% risk of stroke (CVA) in a large study presented at the meeting of the American Stroke Association.

Some studies have linked coffee consumption to several health benefits such as reduced risk of diabetes, some cancers, cognitive decline and Alzheimer’s disease. The results of studies on the effects of coffee on the risk of stroke are contradictory.

Yangmei Li of the University of Cambridge (England) and his colleagues conducted the study with 9.978 men and 12.254 women (average age 59 years) in the United Kingdom participating in European Prospective Investigation Study Into Cancer (EPIC) -Norfolk. They were followed for 12 years on average.

The risk of stroke (stroke) was reduced by 30% among participants taking a cup of coffee per day. Greater consumption did not increase the protective effect. Among those who smoked the risk reduction was 61%.

The researchers can not identify a mechanism explaining the beneficial effect, but they suggest that substances in coffee may be beneficial in improving insulin sensitivity, inhibiting platelet aggregation and reducing endothelial dysfunction. The cafe also has antioxidant properties.
