Which of the following is a source of monounsaturated fats (MUFA)?

Monounsaturated fats (MUFA) are a type of dietary fat that is typically liquid at room temperature and becomes solid when refrigerated. They are known for their heart-healthy properties and are found in various natural food sources. Olive oil is a prime example of a source of monounsaturated fats. It is well-researched for its health benefits, such as lowering bad cholesterol levels and reducing the risk of heart disease.

Olive oil is rich in oleic acid, which is a type of monounsaturated fat that can help promote overall cardiovascular health. Incorporating olive oil into one's diet can also contribute beneficial antioxidants and anti-inflammatory compounds.

In contrast, saturated animal fats, butter, and hydrogenated oils do not primarily provide monounsaturated fats. Saturated fats are typically solid at room temperature and are associated with an increased risk of cardiovascular diseases when consumed in excess. Hydrogenated oils, often found in processed foods, can contain trans fats, which are detrimental to heart health. These fats do not contribute positively in the same way that monounsaturated fats do. Thus, olive oil stands out as the beneficial source of MUFA in the list.
