All fats are not created equal, and monounsaturated fat is among the best of the fatty acids.
Monounsaturated fats, or MUFAs, are normally liquid at room temperature, but become solid when chilled. MUFAs differ from polyunsaturated fats in their chemical composition - MUFAs have only one double-bonded carbon per molecule.
While all fats contain the same number of calories, monounsaturated fatty acids have significant health benefits.
How much you should have: 25 to 30 percent of the daily diet should consist of fats. The vast majority of these fats should be either monounsaturated or polyunsaturated fats.
