What distinguishes monounsaturated fats from other types of fats?

Monounsaturated fats are characterized by having one double bond in their fatty acid chain. This specific structural feature is what sets them apart from saturated fats, which contain no double bonds, and polyunsaturated fats, which contain multiple double bonds.

Fats that contain one double bond have a more fluid structure than saturated fats and can have beneficial effects on heart health by helping to lower bad cholesterol levels when consumed in moderation. Common sources of monounsaturated fats include olive oil, avocados, and nuts. Understanding this unique characteristic of monounsaturated fats highlights their role in a healthy diet and distinguishes them from other fat types.
