All animal food can be divided into six classic food substances—carbohydrates, protein, fat and oil[lipids], mineral salts, vitamins and water.

Carbohydrates, proteins, fats, oil, and water are the primary food substances for the body's system because they are necessary for maintaining life. The first three, carbohydrates, proteins, fats, and oils, together with nucleic acid, are the primary chemicals for the organisms. Mineral salts and vitamins are known as the welfare food substances because of their essential benefit for the well-being of individuals.

CARBOHYDRATES:- are made up of carbon, oxygen and hydrogen. There are different types of carbohydrates, such as sugar, starch and cellulose.

Carbohydrates are the body's primary source of energy. They are used to build specific body parts, e.g. (the Exoskeleton of arthropods). Mucus is an essential lubricant in one's body which coprises with carbohydrates.

SIMPLE SUGAR:- Simple sugar is ordinary within the organism, the hexose(six-carbon) sugar. They are one of the essential storage molecules in an organism. The chemical formula is c6H12O6. Examples are glucose, fructose and galactose. As for ribose and deoxyribose, they are the (five-carbon) known as pentose sugar, which is used to form nucleic acids.

COMPLEX SUGAR:-It is formed by the joining of two simple sugar molecules. They have more complicated chemical formulae, such as (C6H22O11).Examples are sucrose, lactose and maltose.

Simple sugar is a transport product that forms inside a plant during photosynthesis. The complex sugar and starch are broken down into simple sugar, and the process of breaking down is known as hydrolysis. The simple and complex sugars are colourless when they are in water.

PROTEIN:-It contains nitrogen with carbon, oxygen, and hydrogen. It is known as the primary body-building substance because of the necessary new cells with the replaced ones. They are involved in the production of enzymes and hormones. Examples are Meat, egg and milk.

Proteins also are large molecules made from small units known as the amiacidscid. Amino acid is twenty-five in number. In some or all proteins, amino acids are present for the protein to be balanced in number occupied. Protein must be broken down into amino acids before the body absorbs it. It is broken down as follows:

Fat and oils are lipids containing high carbon and hydrogen with small oxygen. Fat is solid, while oil is liquid at room temperature, which produces energy. They are the solvents of hormones and vitamins with essential cell membrane components.

Fat and oil are also known as large molecules absorbed into the body system, which must be broken into fatty acids [glycerol and carboxylic acids]. They are found in margarine groundnut, cheese and fatty Meat.

WATER: About 60-70 per cent of a human being's body is due to water. It is made up of high protoplasm, which is also essential in transporting substances, such as the digestion of food particles, hormones and excretory products. All enzymes always need water to work in.

MINERAL SALTS: They are involved in regulating the body's metabolism. Some of their components are enzymes, pigments and the structural part. The diet gives us most minerals such as phosphorus, sodium and calcium. All these are in large quantities, while the little we need in our body system is just iodine and iron in small amounts. If there is a lack or unavailability of mineral salt, it will lead to ill health.

VITAMINS:-They are organic compounds, as they say, that produce food energy. They are called biocatalysts because they promote the chemical reaction in the body.

Vitamins A, E, D, and K are the fat solution, while B AND C are the water solution—palm oil, fruit and vegetable.

Growing taller and nutrition are closely correlated. Cell division and development require an adequate energy supply and amino acids, water, lipids, vitamins, and minerals. With food, people receive about 50 essential nutrients for growth. Inadequate amounts of food or food that is too low-caloric is the primary cause of growth failure, especially when the growth velocity is high in children.
