Olive Oil Emerges as the Healthier Fat, Experts Say
Nutrition experts say olive oil is generally healthier than butter due to its higher unsaturated fats and links to lower heart disease risk; butter is high in saturated fat, and replacing butter with plant-based oils is associated with lower mortality in large studies. Butter can be enjoyed in moderation, but olive oil is recommended for everyday cooking to support heart and metabolic health, per the 2025–2030 Dietary Guidelines and expert guidance.
