Child Nutrition Flashcards
what are the 3 phases of child growth?
infant (nutrient led)
child (growth hormone led)
pubertal (sex steroid led)
these phases gradually merge
what is LRNI?
dietary reference value
lower reference nutrient intake = sufficient for 3% of the population with the lowest needs
what is EAR?
dietary reference value
estimated average requirement = used for energy requirements of a population
- about 1/2 will need more than the EAR and 1/2 will need less
what is RNI?
reference nutrient intake = sufficient for 97% of the population
what is the RNI for protein at each age range?
4-6 months = 12.7g
7-9 months = 13.7g
10-11 months = 14.9g
12-18 months = 14.5
how are RNI values for protein met?
generally above the RNI value
what is energy reference values for 0-12 months based on?
energy deposited in new tissues + TEE
- TEE = total energy expenditure (including metabolism, growth etc)
what is energy reference value for 1-18 years based on?
TEE + deposited energy costs using model BMR X PAL
- BMR = basal metabolic rate
- PAL = physical activity level
what does energy deposit equate to?
1% increase in PAL
what is the vitamin A RNI and what are some dietary sources?
RNI = 350-400 micrograms sources - cheese - eggs - yoghurt
is it a worry that over half of children exceed the EAR for energy requirement?
not really
by definition of EAR, half of the population will need more than the EAR for energy
what is the RNI for vitamin C and what are some sources?
RNI = 25-30 mg sources - oranges - blackcurrants - potatoes
what is the RNI for vitamin D and what are some sources?
7-8.5 micrograms
sources
- sunlight
- small amounts in oily fish, eggs
are vitamin D RNI met?
usually not due to lack of sunlight in scotland
should children from 6 months old be taking vitamin supplements?
yes
all children consuming <500ml per day of infant formula should take vitamins A, C and D supplements
