Diet Quality Trumps Fat vs. Carbs for Heart Health
12 Feb
Summary
- Healthy low-fat and low-carb diets reduce artery hardening risk.
- Diet quality, not just macronutrient balance, is key.
- Metabolite analysis confirmed diet's impact on heart disease.
New research indicates that both healthy low-fat and low-carbohydrate diets are associated with a reduced risk of coronary heart disease, commonly known as hardening of the arteries. This observational study, involving nearly 200,000 adults over more than 30 years, found that adherence to diets prioritizing plant-based foods, whole grains, and unsaturated fats was linked to better outcomes.
The study, published in the Journal of the American College of Cardiology, also revealed that diets high in refined carbohydrates and animal-based fats and proteins, regardless of their fat or carb content, increased heart disease risk. Lead author Dr. Qi Sun stressed that "It's the quality of your diet that matters," not simply the macronutrient breakdown.
Researchers further validated their findings by analyzing blood metabolites, objective markers that confirmed the link between diet quality and reduced coronary heart disease risk. This approach provided greater confidence in the results, reinforcing the understanding that nutrient-dense foods are crucial for heart health.
