Classes of Food Substances
 
1. Carbohydrates
Molecules of carbohydrate contain Carbon, Hydrogen and Oxygen atoms. Carbohydrates are classified as monosaccharides, disaccharides, or polysaccharides depending on the number of monomer (sugar) units they contain. Examples of carbohydrate are potato, cassava, yam, etc. The ratio of Hydrogen to oxygen is 2:1 as in the case with water. Carbohydrates provide the body energy that is required to carry out daily activities and exercise. Other extra energy that is not use is stored in the body until it is needed.

2. Proteins
The molecules of protein consist of Nitrogen, Carbon, Hydrogen, Oxygen and at times Sulphur. Simple proteins (monomers) are used to produce complex protein (polymers) which build and revamp tissue.  Examples of proteins are egg-white(albumen), lean meat, fish etc. They can also supply energy as well (in the absence of carbohydrates and fats). This is done by the liver. Protein is required for building and repair of body tissues (including muscle)

3. Fats and Oils
They are also referred to as Lipids. The molecules consist of Carbon, Hydrogen, and Oxygen atoms just like carbohydrates, but of low oxygen ratio. They contain more calories of energy than carbohydrates which are not as readily available. They help in insulation of the body. Examples of Lipids are butter, groundnut, palm oil etc.

4. Water
This is the medium for chemical reactions in every living organisms. It helps in transportation as well as temperature control. It can be got in nature from streams, rivers, as rain, ocean and sea. About 70% of the non-fat mass of the human body is water. Water helps to transports oxygen and nutrients to different parts of the body, helps to removes toxins and wastes from the body, water also helps to regulates body temperature through perpetration.
