The “coffee drinkers are less likely to have diabetes” idea has popped up again, this time focused on those who have coffee with lunch. From the abstract,
[T]he hazard ratio in the highest category of coffee consumption [
3 cups (375 mL)/d] was 0.73 … in comparison with no coffee consumption. This inverse association was restricted to coffee consumed at lunchtime (hazard ratio: 0.66 …) when comparing >1.1 cup (125 mL)/meal with no intake.
.73 or .66 on an observational study doesn’t seem all that huge. What struck me was how the lower chance of diabetes was associated with women who drank coffee at lunch. Generally when I have coffee with lunch, it’s actually at the end of the lunch — a sign that I have time to de-stress a bit more and relax. Stress is known to influence blood glucose levels in non-diabetics as well as diabetics….
But is my experience (coffee with lunch meaning de-stress time) what most people experience? Or is it really something in coffee? Right now, there’s no way to know — and I doubt this is going to be double-blind tested anytime soon ;)
