Unsaturated fats part 2
Unsaturated fats may be mono-unsaturated (if a fatty acid hydrocarbon chain has only one pair of neighboring carbon atoms in an unsaturated state—that is, has only one double bond) or polyunsaturated (if more than one pair of carbons is unsaturated—there’s more than one double bond). Unsaturated fats are still high in calories, but because they can lower cholesterol, they are generally preferable to saturated fats. Foods high in unsaturated fats include avocados, peanuts,and olive oil. Relative to other animals, fish tend to have less saturated fat.
