Grass fed meat and coconut oil also will come under this. When we talk about the unsaturated fatty acids they are liquid state at the room temperature. MUFAs contains one double bond which will make them at room temperature in the liquid state and PUFAs contain several double bonds in their structure. The sources of the healthy monounsaturated fatty acids are virgin olive oil, and these are related to good cholesterol and provide the better insulin resistance and they hep in reducing the belly fat and reduction of the risk of the heart disease.
