Polyunsaturated fats are a class of fats whose fatty acid structures contain multiple double bonds between the carbons that are part of their molecular structure. Two frequently discussed subclasses of polyunsaturated fatty acids are Omega-3s and Omega-6s.

Health considerations

The American Heart Association encourages consumption of polyunsaturated fats in moderation, particularly in lieu of saturated and trans fats; multiple clinical studies show fewer coronary events with this diet pattern. See: Omega-3 fatty acids, Omega-6 fatty acids.
