Dueling studies: Coffee
University of South Australia: “Excess coffee consumption a culprit for poor health”
… too much coffee can increase the risk of osteoarthritis, arthropathy (joint disease) and obesity. […] six cups* of coffee a day were considered the upper limit of safe consumption.
Anglia Ruskin University: “Coffee linked to lower body fat in women”
Overall, the average total body fat percentage was 2.8% lower among women of all ages who drank two or three cups of coffee per day.
Among women aged between 45–69, those who drank four or more cups had an adiposity percentage 4.1% lower.
So they’re not really contradictory — together they reinforce the current thinking that four to six cups* of coffee a day is the sweet spot. We’ll stick with that.
