Q. I know olive oil is part of a heart-healthy diet, but is extra-virgin olive oil healthier than regular olive oil?
A. Many studies continue to confirm the health benefits of the Mediterranean diet, which cuts the risk of heart disease and stroke. The diet’s nutritional benefits probably come from various sources, but the generous use of olive oil appears to be a key contributor.
Regardless of the type, olive oil is high in monounsaturated fatty acids, containing about 75% by volume. When substituted for saturated fat, monounsaturated fats help lower your “bad” LDL cholesterol. The health benefits of olive oil have been attributed to its antioxidant and anti-inflammatory properties. In fact, observational studies have shown a link between lower risks of cardiovascular disease, some cancers, and even dementia in people who consume higher amounts of olive oil than those who use little or none.
