It’s one of the most enjoyable things we can do for a healthy heart. Drinking red wine. Well now there’s a bit of a caveat.
New research suggests while one glass may be healthy, two or more could actually do more harm than good over time. Previous studies have suggested light or moderate drinking has a protective effect on the heart, and red wine was singled out as having specific benefits. The studies found lower rates of heart disease in some European populations that regularly consume red wine. A new study by Toronto’s Peter Munk Cardiac Centre found that a single glass of red wine did have potentially helpful effects. But it also found that after two glasses, test subjects’ heart rates rose and their hearts began pumping more blood than necessary.
Dr. John Floras says those two reactions may be partly why heavy drinking has been shown to have adverse effects.
These findings are in the American Journal of Physiology.
