Registered dietitians outline a simple kitchen substitution—using extra virgin olive oil instead of butter or other fats—and why it matters for heart health. The guidance centers on extra virgin olive oil and the Mediterranean diet, noting a 2022 Harvard study in the Journal of the American College of Cardiology that associates this swap with longer life potential. The video compares saturated fat in butter (about 7 g per tablespoon) with olive oil (about 1.9 g) and highlights monounsaturated fats and polyphenols. Research including the PREDIMED trial is cited, alongside heat stability and a baking ratio of three-quarters cup oil per cup of butter.
