Even though olive oil is high in fat, it is actually one of the healthiest foods in the world. Olive oil is the cornerstone of the Mediterranean diet and its health benefits are unrivaled.
Olive oil is a basic ingredient in a large number of Mediterranean dishes, such as pasta, fish and salads. Studies have repeatedly associated the Mediterranean diet with a decreased risk of heart disease. Olive oil is high in monosaturated fats, which are considered "good fats." A high intake of monosaturated fats can help lower LDL or "bad" cholesterol. Olive oil is one of the best ways to add good fat to a diet and avoid the bad fat present in commonly used ingredients, such as butter and shortening.
Olive oil has been shown top reduce the risk of type 2 diabetes by almost 50 percent when compared to a regular low-fat diet, according to a study published in "Diabetes Care in 2010. Another study published in the online medical journal of the American Academy of Neurology showed that olive oil might help prevent strokes. Moreover, a study published in the "American Journal of Clinical Nutrition" indicated that olive oil may be able to slow down the aging process of the heart.
