What we think and what we eat, combined together, make what we are, physically and mentally” 

Edgar Caycee

World Health Organization (WHO) has defined “health” as a state of complete physical, mental, social and spiritual well-being and not merely the absence of disease or infirmity.

The key to a good health is good nutrition and the cornerstone for good nutrition is a balanced diet. A balanced diet is one that contains different food items in the right proportions and amounts, so that all the nutrients are provided in required quantities. To ensure the same, it is advisable to include in the diet the food items from various food groups as indicated in the food pyramid.

Functional classification of food

  • Energy giving foods (carbohydrates and fats) – are responsible for providing energy for various activities.
  • Body building foods (proteins and minerals) – are responsible for tissue building, growth, repair and maintenance of the body.
  • Protective foods (vitamins and minerals) – play an important role in protecting the body against diseases.
  • Regulatory foods (water and fibre) – are responsible for regulating body processes like digestion, excretion, regulation of body temperature and electrolyte balance.
