Balanced Diet — a diet that provides all necessary nutrients in the correct amounts. Example: An athlete needs more energy nutrients than an office worker. Malnutrition — lack of proper nutrition due to insufficient or excessive intake of nutrients. Example: Protein-energy malnutrition can be lethal due to lack of energy. Micronutrient Deficiency — insufficient intake of essential vitamins and minerals. Example: Iron deficiency can cause tiredness and lethargy.
