Proteins are key components in a diet because all the cells and all the tissues in the body contain protein. Protein is there to help people’s growth and repairs the body from damage. Proteins are made up of amino acids. Meat, poultry, milk and fish contain protein and all the essential amino acids. Proteins can be from plant sources such as rice, wheat, corn and beans these proteins do not contain all the amino acids needed. If you do not get enough protein in your diet then you might not grow properly and your body will not be able to repair itself when you are ill or if you get injured.

Carbohydrates are key components in a diet because they provide the body with energy. Carbohydrates are in comprising sugars, starchy food and dietary fibre. Starchy carbohydrates provide an important source of energy. Simple carbohydrates or sugars this is found in food such as fruit, vegetables, honey, milk and malt products. Simple carbohydrates are digested by the body quicker because they have got a simple chemical structure. Complex carbohydrates are found in cereals, corn flour, potatoes, pasta and flour. Complex carbohydrates absorb certain minerals and fatty acids. If you do not have enough carbohydrates then you would be tired and not have enough energy to do what you need to do in the day.
