Coffee won’t actually clean out your arteries, but it could help protect against cardiovascular disease. A recent study reports that people drinking 3-5 cups of coffee a day were 41% less likely to show signs of coronary artery calcium than non-coffee drinkers. This calcification is an early indicator of the artery-clogging plaques – atherosclerosis, or hardening of the arteries – that causes coronary artery disease, the number one killer of Americans. More good news to perk up coffee drinkers: experts say there are also observational studies that indicate coffee intake is associated with lower risk of type 2 diabetes and dementia.
But beware: people drinking more that 5 cups of coffee daily actually saw greater risk for arterial plaques than moderate coffee drinkers…so more isn’t actually better!
