Olive Oil Linked with Lower Risk of Heart Disease

Not all fats are created equal. Olive oil is a source of heart-healthy monounsaturated fats and polyphenols, while butter is a source of saturated fats. In this study, researchers followed more than 90,000 people for 24 years. Those eating more than ½ tablespoon of olive oil per day had a 14-17% lower risk of heart disease compared with people who didn’t eat olive oil. The scientists also found that replacing 5g/day of butter, margarine, mayonnaise, or dairy fat with the equivalent amount of olive oil was also linked with a 5-7% lower risk of heart disease.
