Omega-3 Fatty Acids: Why are they essential for your body?

Omega-3 fatty acids are a group of polyunsaturated fatty acids. They are essential for a number of functions in the body. 

There are 3 primary omega-3 fatty acids. They are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). The omega-3 fatty acids are mainly found in seafood such as fatty fish and shellfish, some vegetable oils such as canola and soy. They are also found in dietary supplements like fish oil, krill oil, cod liver oil, and algal oil. 

Here are some benefits of omega-3 fatty acids.

  • Reduces risk of heart diseases
  • Helps to fight depression and anxiety
  • Improves bone and joint health
  • Helps to fight autoimmune diseases
  • Prevents non-alcoholic fatty liver diseases
  • May help prevent cancer
  • Reduces menstrual pain
  • May help to improve sleep

A deficiency of omega-3 can cause rough, scaly skin, and dermatitis. Plasma and tissue concentrations of DHA decrease if you are not getting enough omega-3 fatty acids.
