25 views2 pages

Document Summary

Growth is rapid during infancy; birth weight doubles in 4-6 months, and length increases by 50% in the first year. An adequate intake diet, especially in terms of calories, protein, and zinc, is essential to support normal growth. Growth charts aid nutritional assessment of infants and children by tracking changes in body weight, height (or length), head circumference, and body mass index over time. The energy needs of infants are highest per kilogram of body weight compared to any other life stage, around 100 kcal/kg. Fat should make up about 50% of total energy intake. Dha and aa are important fatty acids for nervous system development. Carbohydrate needs range from 60 grams per day for younger infants to 95 grams per day for older infants. Protein needs are 9 grams per day for younger infants and 11 grams per day for older infants. Supplementation with vitamin d, iron, and fluoride may be appropriate for some infants.
