Food Quality Trumps Macros for Heart Health, Large Study Finds

A Harvard-led analysis of nearly 200,000 U.S. health professionals followed for about 30 years finds heart health improves when diets emphasize quality—vegetables, fruits, whole grains and healthy fats—while reducing processed foods and excess animal fats, rather than simply counting carbs or fats; this is linked to better cholesterol, lower inflammation, and a lower risk of coronary heart disease, with the study spanning over 5.2 million person-years and published in the Journal of the American College of Cardiology.
