Harvard Study Finds Food Quality Trumps Carbs and Fats for Heart Health
A Harvard-backed study found that low-carb and low-fat diets are associated with reduced coronary heart disease risk only when they emphasize high-quality carbohydrates and plant-based proteins and fats; such diets showed about a 15% lower risk, while those rich in refined carbs and animal products raised risk. The takeaway is that food quality matters more than quantity for heart health.
