Nutrition Requirements

The Food and Agriculture Organization of the United Nations (FAO) provides scientific advice on nutrient requirements to Member Countries and international bodies, including the Codex Alimentarius Commission. National and international agencies use this information for developing policies and programmes for actions to improve nutrition throughout the world. FAO activities on nutritional requirements include development of practical applications and tools for improving nutrition, such as nutrition labelling, training workshops and research related to nutrient requirements.

The first committee on calorie (energy) requirements made a number of points which are still pertinent today. Among the most important were:

  • Requirements were intended for groups of persons rather than individuals, i.e., an average requirement can never be compared directly with an individual (requirement).
  • Judgement must be exercised in interpreting and using requirement values.
  • It is essential to address the practical applications of the requirements, a task assigned to the Secretariat.
