Omega 3 is a type of fatty acid which is useful for the body. However, our body can not make its own omega 3 fatty acid. This is the reason why we need to nourish our body with Omega 3 from diet and supplements.
Omega 3 fatty acids are found in seafish, fish oils, flax seeds, walnuts and chia seeds.
People who do not eat fish often take supplements to fulfill their body requirements of omega 3.
There are three main types of Omega 3: Alpha-linolenic acid which is used by the body for energy, Eicosapentaenoic acid which is mostly found in fish and Docosahexaenoic acid which is a structural component of brain, retina and other body parts.
Research studies have linked the consumption of omega 3 fatty acids with reduction in cases of breast cancer, depression, and several inflammatory diseases.
