The macro nutrients are Carbohydrate, Fat and Protein and these are required most in our diet.
Carbohydrates are stored in the liver as glycogen or converted into fat in the rest of the body
Fat is made of fatty acid and glycerol. This is stored as adipose tissue around the organs and under the skin.
Amino acids are found in proteins but are also made by your body.
Essential amino acids come from your diet.
Animal protein is a First Class Protein. These contain the essential amino acids.
Plant protein is a Second Class Protein. These do not contain the amino acids.
The amount of these foods should be varied so that you can get a good amount of each.
