If you are really health conscious and want to avoid fatty acids, then you should know how to differentiate between saturated and unsaturated fatty acids. There is a vast difference between these acids. The difference is in the fat content in it.
Saturated fatty acids are those acids which contain high cholestrol which leads to cancer. Unsaturated fatty acids conatins double bounded atoms of carbon where as, saturated acids contains hydrogen atoms.
Saturated fatty acids should be taken in minimum amount because they contain more cholestrol than unsaturated. Saturated fatty acids are found in those products which are made up of animal contents.
Unsaturated fatty acids are those which are in liquid state at room temperature. Saturated fatty acids are solid at room temperature. Sunflower oil, olive oil, corn oil are some of the examples of unsaturated fatty acids. Butter is an example of saturated fatty acids. So, you can prefer having unsaturated fatty acid more, than to have saturated fatty acids.
