NUTRITIONAL REQUIREMENTS AT DIFFERENT LIFE STAGES (5)
Infants :- The first 4-6 months are a period of rapid growth and development. Breast milk contains all the nutrients required during this period. Exclusive breast feeding should be encouraged till 6 months of age with introduction of weaning diet after that. Weaning food should meet the requirement of iron, proteins, thiamine, niacin, vitamin B6 & B12, magnesium, zinc, sodium and chloride.

1-3 years of age :- Preschools are rapidly growing and have greater energy requirement. There is increased need for all vitamins and minerals except Vitamin D & zinc. Lesser amounts of calcium, phosphorus and iron are needed as compared to earlier. Fibre (non starch polysaccharide) should also be added to meet the satiety needs. Protein requirements do not increase much.

4-6 years of age :- Energy requirements continue to increase as well as proteins, vitamins *except C & D) and all minerals (except iron).

7-10 years :- Energy, protein, vitamin and mineral requirements increase. Requirement for thiamine, vitamin C & D remain same.

11-14 years :- Protein requirement increases by 50%. Energy requirement continues to increase. Boys require increased vitamins and minerals whereas in girls iron requirement is very high and there is no change in requirement of thiamine, niacin & vitamin B6.

15-18 years :- Energy, protein, vitamin and mineral requirement increases with same requirement of vitamin B12, folate, vitamin C, magnesium, sodium, potassium, chloride and copper. Calcium and iron requirement markedly increases.

Conclusion
Children are growing both physically and mentally and adequate nutrient supply is necessary to maintain the genetically programmed growth potential as well as immune system development. Impairment at both micronutrient as well as macronutrient level can lead to maladjustment and improper growth and development with chronic long term health consequences.
