Diet and Exercise Planning: Polyunsaturated Fats

Posted February 15th, 2006 by admin

Learn more about today’s diet and exercise planning: understanding polyunsaturated fats.

Understanding your fats can help you live a longer life by implementing your knowledge. Not all fats are created equal. It is up to the consumer to be educated on what is good for you and what is not.

The polyunsaturated fat is a type of triglyceride. This triglyceride has fatty acids that contain more than one double bond, hence the word poly. Double bonds in natural fats are rigid and introduce a kink in the molecule. This kink prevents the fatty acids from packing close together. This is why unsaturated fats have a lower melting point than saturated fats. Also, saturated fats are solids at room temperature while unsaturated fats are liquid at room temperature and referred to as oils.

Omega-6 fats are a type of polyunsaturated fat. The omega-6 fatty acid (linoleic acid) is obtained from vegetable oils. This fatty acid helps to protect against heart disease. Nuts, avocados, olives, soybeans, along with sesame, cottonseed, and corn oil are good sources of omega-6 fats. Try to include these fats in your diet for better health.
