Kavungya
A balanced diet consists of all the food types in their right proportions; it includes
proteins,carbohydrates, minerals, lipids, water, vitamins and roughage;
Proteins; used for growth and repair of worn out tissues; provide energy incase of acute
shortage of carbohydrates/starvation; bind and transport specific molecules from one part of
the body to another;structural proteins support tissues in the body e.g. bone and cartilage
tissues; act as metabolic regulators such as enzymes and hormones;
Carbohydrates; used to produce energy/store energy;
Lipids produce energy; form of storage of energy; insulate the body; major structural
components of the cell membrane; when oxidised, it provides metabolic water;
Vitamins; defense against infections; form coenzymes which activate enzymes;
Water; a universal solvent; medium for chemical reactions; used as coolant because of its high
specific heat capacity; maintains the shape of cells; hydrolysis of many substances; transport
medium in the body;
Mineral salts; formation of teeth and bones; formation of hormones (e.g. thyroxine); formation
of blood; maintenance of osmotic pressure of body fluid; transmission of nerve impulses;
Roughage; makes food to be bulk; promotes peristalsis; and absorption of water in the large
intestines; induces mucus production;
