polyunsaturate
Heart-healthy lipid type
A polyunsaturate is a fat or fatty acid containing multiple double bonds between carbon atoms in its molecular chain.
The term appears mainly in nutrition contexts, where polyunsaturates—found in fish, nuts, and vegetable oils—are considered healthier than saturated fats: The diet emphasizes polyunsaturates over animal fats.
