The Role of Omega-3 Fatty Acid

In the present day scenario, we all are so busy that we forget to take care of something essential for us to function well. We have, perhaps, forgotten that a healthy body is one of the vital requirements for a person to be professionally efficient and productive. Have we ever thought that our body needs essential nutrients like the omega-3 fatty acid?

We are all aware of the role that nutrition plays in maintaining good health. But do we eat what we need? Do we consider the needs of our bodies before selecting our meals? It is time that we stop just eating. Time has come that we start eating mindfully.

It is essential to understand that the food which we eat is not only supposed to be tasty. But, it should also have all the vital nutrients which help our body to function correctly. All seven nutrients combine and provide us with the energy to work efficiently. The food which we eat is worthy only when it has an adequate proportion of all the nutrients.

To eat properly, we must be aware of the role that each nutrient plays in maintaining good health. There are two main nutrient groups. They are macronutrients and micronutrients. We have already discussed the role that protein plays in maintaining a healthy body.

Like protein, omega-3 fatty acids are also a part of the macronutrient group. Omega-3 fatty acids are yet another form of macronutrients which are essential for our overall health and well being.

It is time to discuss omega-3 fatty acids in detail. A detailed discussion will help us include an appropriate amount of omega-3 fatty acid in our daily diet in the form of food or dietary supplements.
