Explain briefly about the Nutrition?

This unit covers the scope of advanced nutrition. It begins with some definitions and basic concepts and briefly traces the history of nutritional sciences. It will make you familiar with terminologies in nutritional requirements such as minimum requirements, recommended dietary intakes (RDls) and dietary reference intake (DRIs), terms that you will come across frequently in the other units as well. The understanding of these concepts would help you to analyze critically the various methods that are employed to study and estimate nutrient requirements. Based on considerable research, different National and International organizations have made recommendations concerning human nutrient requirements. You will learn about these and their application in different settings in the final section of this unit.
