High-protein diets boost artery-clogging plaque, mouse study shows ... read more
January 23, 2020
High-protein diets may help people lose weight and build muscle, but a new study in mice suggests they have a down side: They lead to more plaque in the arteries. Further, the new research shows that high-protein diets spur unstable plaque -- the kind most prone to rupturing and causing blocked arteries. More plaque buildup in the arteries, particularly if it's unstable, increases the risk of heart attack.
