You must have heard about unsaturated fats, such omega-3 fatty acids. These unsaturated fats are good for the body's health in a number of different ways. Although the human body needs certain fatty acids, it is unable to create them on its own and must thus receive them through diet.

Omega-3 fatty acids are essential for healthy cell activity and are significant for many biological processes. Fatty fish, seaweed, flaxseeds, and chia seeds are a few food sources.

Due to the fact that omega-3s are an important fatty acid kind, people must consume them in their diet. Today in this article we will tell you about the various benefits of Omega-3 fatty acids.

What are Omega-3 fatty acids?

Omega-3 fatty acids are a type of polyunsaturated fatty acid that are essential for good health. There are three main types of omega-3 fatty acids,

  • EPA (eicosapentaenoic acid)

  • DHA (docosahexaenoic acid)

  • ALA (alpha-linolenic acid).

EPA and DHA are mainly found in fatty fish such as salmon, tuna, sardines, and mackerel, as well as in fish oil supplements. ALA, on the other hand, is found in plant-based sources such as flaxseeds, chia seeds, and walnuts, as well as in oils such as canola oil and soybean oil.
