Olive oils are natural oils extracted from the fruit of the olive tree, primarily grown in Mediterranean regions. They are known for their rich flavor and health benefits, including high levels of monounsaturated fats and antioxidants. The quality of olive oil can vary based on factors like the type of olives used, the extraction process, and the region of production. There are several types of olive oil, including extra virgin olive oil, which is made from pure, cold-pressed olives and has the highest quality. Other types include virgin olive oil and refined olive oil, which undergo different processing methods. Olive oil is commonly used in cooking, dressings, and marinades.
