High coffee consumption could be associated with a rduced risk of type 2 diabetes, Dutch researchers suggest.
Caffeine is known to reduce sensitivity to insulin, although other components of coffee such as magnesium and chlorogenic acid could offer some health benefits. Rob van Dam and colleagues from the Dutch national Institute for Public Health and the Environment, Bilthoven, prospectively assessed the effect of varying coffee consumption on the development of type 2 diabetes in around 17,000 Dutch adults.
In a research letter in this week’s issue of the Lancet they report how individuals with high coffee consumption-those who drank seven or more cups of coffee a day-were 50% less likely to develop type-2 diabetes compared with less frequent coffee drinkers, even when confounding factors (e.g. smoking, alcohol consumption, and body mass) were taken into account.
Rob van Dam comments: “In view of the widespread use of coffee and the large health burden of type 2 diabetes, our finding of an inverse association between coffee consumption and risk of type 2 diabetes could have important public-health implications. However, our findings need to be replicated and possible adverse effects on other health aspects should be considered in the choice to consume coffee.”
