Low-fat or low-carb — which is better for heart health? The answer may surprise you

February 11, 2026 - 21:54

The long-standing debate over whether a low-fat or low-carbohydrate diet is superior for heart health may be missing the point entirely. Emerging research indicates that the primary factor for reducing the risk of coronary heart disease is not the macronutrient you restrict, but the overall quality of the foods you choose to eat.

Scientists emphasize that a high-quality diet, rich in whole grains and plant-based foods, is consistently linked to better cardiovascular outcomes. This means prioritizing unprocessed items like vegetables, fruits, legumes, and whole grains, while minimizing intake of refined sugars, processed meats, and heavily processed carbohydrates, regardless of their fat content.

The findings suggest that individuals can potentially see heart health benefits from various dietary patterns—be they nominally lower in fat or carbohydrates—provided the foundation is built on nutritious, whole foods. This shifts the focus from a simplistic nutrient war to a more holistic view of dietary patterns, where food quality reigns supreme for long-term wellness.
