Childhood to Late Adulthood Flashcards
Does energy needs increase or decrease as you age?
Why
Decreases because BMI decreases 1-2% per decade
reduces PA
Needs for carbs young
After one year is the same as an adults
Needs for fibre r/t to energy intake young
14g of fibre for every 100
minimum is age +5g
Needs for protein young
increases as kidney’s and liver mature
protein isn’t stored, it’s excreted
we don’t want too much because Nitrogen is a by-product
2 servings of milk is good
Lipids young
decreases w age
1-3 = higher 30-40%
4-13 = decreased 25-35%
Needs for iron in younger children
1-8 need 7-10mg daily
0-12 months get high amounts of iron from breastmilk because of bioavailability
What happens when a child skips breakfast? Why?
Liver can’t store carbs for a long time so the brain can’t function properly
Overnight fasting = “starvation” for children
One of the consequences of a vegan diet for children
Too much fibre intake (inhibits zinc and iron absorption)
Food allergies respond with
Ab and may or may not have symptoms
Food intolerance responds with
(food hypersensitivity)
- symptoms but no Ab
Examples
Chemicals and enzyme deficiency
Reasons for childhood obesity (3)
- Genetics
- Poor nutrition choices
- Less physical activity, more time spent at home
Three main nutritional factors
1) total energy intake
2) nutrient density
3) fat content
Growth spurt ages and energy needs
girls 10-11 - peaks earlier but declines faster
males 12-13 - peaks later, but at a higher rate
Needs for iron in adol. children
Iron
- increases for males because of lean body mass; gradually decreases back to normal
- increases in females because period, RDA remains high
Needs for vitamin D and calcium
- important for optimal peak bone density
