NUTRIENTS

                                NUTRIENTS:

The naturally occurring food components that are utilized by the human body and provide nourishment are called nutrients that perform functions such as energy giving,bodybuilding etc.

Food exists in nature as a simple assimilable materials or as complex mixtures of chemical compounds.

This may range from a simple common salt molecule to fruits,cereals and milk...

                  CLASSIFICATION OF NUTRIENTS:

Nutrients are usually classified into two classes,by the nutrients,including

• macronutrients

• micronutrients

MACRONUTRIENTS:

Macronutrients are the nutrients required by the body in large amounts,and are

1. Water
2. Carbohydrates
3. Fats
4. Proteins

Functions of macronutrients:  These *constitute bulk of the diet  * supply energy for body activity  *building blocks needed for growth and maintenance.They also provide compounds that regulate body processes.

MICRONUTRIENTS:

Micronutrients are the ones required in smaller quantities,milligrams(mg),micrograms(µg).These are

1. Vitamins
2. Minerals                     ,.,that catalyse the utilization of the macronutrients...!!!
