The best oil for general use in the United States is olive oil. Olive oil is widely recognized for its health benefits, which include high levels of monounsaturated fats, antioxidants, and anti-inflammatory properties. According to the American Heart Association, replacing saturated fats with monounsaturated fats like those found in olive oil can help lower bad cholesterol levels and reduce the risk of heart disease.

Data from the Centers for Disease Control and Prevention (CDC) indicates that olive oil is a staple in the Mediterranean diet, which is associated with a lower risk of chronic diseases such as heart disease, stroke, and type 2 diabetes. The Mediterranean diet emphasizes the use of olive oil as a primary source of dietary fat, and research has shown that this dietary pattern can lead to improved cardiovascular health and longevity. Additionally, the European Society of Cardiology recommends using olive oil as part of a healthy diet to prevent heart disease.
