Basically, dietary fats are classified into two types- saturated and unsaturated. Saturated fats have no double bonds in their structure, but, unsaturated fats have one or more double bonds in their structure. Many studies have shown that replacement of saturated fats with polyunsaturated fatty acids can decrease or even eliminate the risks of coronary heart disease and many other health issues too. Now, let’s have a look on what actually are polyunsaturated fatty acids.

These types of fats are considered healthy, and contain more than one double bond in the backbone of their structure. They have a carbon and hydrogen chain in each molecule.

A type of dietary fat, it is found in both animal and plant derived foods. 

Types of polyunsaturated fatty acids: 

There are various types of polyunsaturated fatty acids. However, out of them, most commonly found forms are omega-3 and omega-6 fatty acids. 

  • Omega-3 fatty acids: the most commonly found polyunsaturated fatty acids, they are found to be quite essential for the functioning of the cells in the human body. Their primary function is to provide energy production and play a vital role in proper functioning of heart, lungs, blood vessels and the immune system.

There are three different types of omega-3 fats:

  • Eicosapentaenoic acid (EPA)
  • Alpha-linoleic acid (ALA)
  • Docosahexaenoic acid (DHA)
  • Omega-6 fatty acids: omega-6 fatty acids can also enhance the quality of life by adding a lot of nutrients to the diet. However, many studies suggest that a diet rich in omega-6 fats and deficient in omega-3 fats can cause inflammation and other issues related to health of the individual. Some fast-foods and sweets also contain highly amounts of omega-6s. Sources of the same are: mayonnaise, tofu, soybean oil, sunflower oil etc.

Sources of polyunsaturated fatty acids:
