***Carbohydrate***
These are large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2:1) and typically can be broken down to release energy in the animal body. Examples of food rich in carbohydrate are food known for high sugar content. Carbohydrate rich food supplies energy to the body.
***Protein***
Protein are nitrogenous organic compounds which have large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, etc., and as enzymes and antibodies.Examples of food rich in protein are meat, milk, eggs, and beans and many more. Protein helps to repair worn out tissues and stimulates body growth

***Vitamins***
These are group of organic compounds which are essential for normal growth and nutrition and are required in small quantities in the diet because they cannot be synthesized by the body.Vitamins could be water soluble or fat soluble, they are majorly found in fruits and vegetables.
