NUTRITION IN

CHILDHOOD


2/30

Nutrient requirement

Children growing & developing

need more nutritious food May be at risk for malnutrition if :

- poor appetite for a long period

- eat a limited number of food- dilute their diets significantly with

nutrient poor foods


3/30

Energy

Energy needs of healthy childrendetermined on :

- basis of basal metabolism

- rate of growth

- energy expenditure

Must be sufficient to ensure growth & spare

protein, but not so excessive Suggested intake proportions :

50 60% carbohydrate, 25 35% fat,

10 15% protein

Early childhood 1.1 g /kg BW

Late childhood 0.95 g/kg BW

At risk for inadequate protein intake :- strict vegan diets

Minerals and vitamins

Necessary for normal growth & development Insufficient intake impaired growth

deficiency disease


8/30

Iron

Children 1 3 years high risk for iron

deficiency anemia Rapid growth period Hb & total iron

diet may not be rich in iron-containing food


9/30

Calcium

Needed for adequate mineralization &maintenance of growing bone

DRI : 1300 mg/day 9 18 yrs800 mg/day 4 8 yrs

500 mg/day 1 3 yrs

Primary sources : milk & dairy product children who consumed no or limitedamountat risk for poor bonemineralization


10/30

Zinc

Essential for growth if deficiency :

- growth failure

- poor appetite- decreased taste acuity

- poor wound healing

RDA : 3 mg / day 1 3 yrs5 mg / day 4 8 yrs

8 mg / day 9 13 yrs


11/30

Best sources : meats & seafood

Marginal zinc deficiency reported in

children from middle & low-income families(Robert & Heyman, 2000)


12/30

Vitamin D

Needed for calcium absorption & deposition

calcium in the bones The amount required from dietary sources

is depend on nondietary factors (geographiclocation & time spent outside)

Primary sources : vitamin D-fortified milk


13/30

Vitamin-Mineral supplement

Do not necessarily fulfill specific nutrient needs

Children who take supplement do not

exceed the RDA Should not take megadoses, particularly fat

soluble vitamins toxicity


14/30

Children at risk who may benefit fromsupplementation :

- from deprived families- with anorexia, poor appetites, poor eating habits

- with chronic diseases (cystic fibrosis, liver dis)

management

- vegetarian diets with inadeq intake of dairy product

or calcium containing foods

of milk only

milk anemia Do not like meat iron consumed in the

nonheme form

caries (Baby bottle tooth decay) Snacks choose that are least cariogenic

Chewing sugarless gum salivary pHbeneficial

Toothbrush should be introduced


24/30

Allergies

Usually develop during infancy &childhood and more likely when family

history (+) Allergic responses most often include

respiratory or GI symptom & skin reaction


25/30

Autism Spectrum Disorders

Affect the childrens nutrient intake & eatingbehaviors

Typically eat only specific foods

restricted diet

at risk for inadequate nutrient intake

Usually refuse fruit & vegetables

Commonly very resistant to taking supplement


26/30

Popular dietary intervention : gluten-free andcasein-free diet

Nutrition assessment should include :

- the possibility of medication and nutrientinteraction

- use of alternative therapies, herbal and

- no more than 300 mg/day of cholesterol

> 2 yrs gradually adopt a lower fat diet4 yrs meet the NCEP guidelines
