Concept

Key idea

Nutrients are substances in food that the body uses. Carbohydrates and fats supply energy. Proteins help growth and repair. Vitamins and minerals support many functions, such as vision, healthy bones, and blood clotting. Water supports body processes, and fibre helps bowel movements. A balanced diet provides a variety of foods in amounts suited to a person's needs. Rice or roti supplies carbohydrates; dal, beans, eggs, or fish supplies protein; fruit and vegetables supply fibre and different vitamins and minerals. Foods often provide more than one nutrient. Too little of a nutrient over time can cause a deficiency. Vitamin C deficiency can cause scurvy; vitamin D deficiency can cause rickets in children; vitamin A deficiency can affect vision in dim light. Iron or vitamin B₁₂ deficiency can cause forms of anaemia. Tiredness alone does not identify a deficiency; a health professional checks the cause.
