Olive oil is primarily composed of monounsaturated fatty acids. These are fatty acids that contain one double bond in their carbon chain. The predominant monounsaturated fatty acid found in olive oil is oleic acid, which has been associated with various health benefits, including better heart health by helping to lower bad cholesterol (LDL) levels and increase good cholesterol (HDL) levels.

Monounsaturated fats are generally considered to be healthier than saturated fats and trans fats because they can help reduce inflammation and improve insulin sensitivity. Furthermore, the consumption of monounsaturated fats, like those in olive oil, is linked to a reduced risk of chronic diseases, including cardiovascular conditions.

While other types of fatty acids are present in various oils and fats, they do not make up the primary fatty acid profile in olive oil. Saturated fats are typically solid at room temperature and are found in higher quantities in animal products and some plant oils. Polyunsaturated fats have multiple double bonds and are present in oils such as sunflower and corn oil but are not predominant in olive oil. Trans fats, which are often found in partially hydrogenated oils, are considered unhealthy and are restricted in many countries due to their adverse health effects.
