The way human body cannot make most of the vitamins and minerals at its own, similarly, omega–3 fatty acids are essential fats which our body cannot make. These fats are to be taken from healthy nutrition. These fats are present in fish, green leafy vegetables, flaxseeds, chia seeds and walnuts. The three types of fatty acids are involved in human physiology, Alpha linolenic acid (ALA) (found in plant oils), Eicosapentaenoic acid (EPA), and Docosahexaenoic acid (DHA) (both commonly found in fish oils).
Due to recent change in style of human nutrition, the balance between consumption of Omega-3 and Omega-6 has been disturbed. We take more Omega-6 fatty acids which are abundant in vegetable oils we consume. Therefore, it is important to take more Omega-3 to correct the imbalance for a better health. Supplementation of Omega-3 can be useful in case required amount is not being taken through daily diet.
Omega-3 may help in improvement of healthy joints, brain and heart. It is also considered good for blood pressure control, better sleep quality and improved skin.
