ppwt 2 - energy and protein reqt for adults Flashcards
Basal metabolic rate
minimal rate of energy expenditure compatible with life
total energy expenditure
energy spent, on average, in a 24h period by an individual or group of individuals
estimated energy requirement
average dietary energy intake that will maintain energy balance in a healthy person of given genre, age, weight, height and physical activity level
EER takes what into account
growth pregnancy, milk produced
What is the recommended PAL
1.6-1.7
total energy expenditure
PA X REE
macronutrient ranges distribution
45-65% carbs
20-35% fat
10-35% protein
ranges of macronutrients for
children 1-3 years
4-18 years
adults
1-3 years:
fat - 30-40
protein 5-20
carb 45-65
4-18 y:
fat : 25-35
protein: 10-30
carb: 45-65
adult
45-65% carbs
20-35% fat
10-35% protein
indicators used to estimate macronutrients requirements
protein: nitrogen balance
carb: minimum required by the brain
fat: median intake of linoleic and alpha linolenic acid
what accounts for free fatty acids
dietary intake and de novo synthesis
what happen to protein
can be excreted, oxidized or go to non protein pathways and they can be also protein losses for skin, hair, feces
what happens to protein synthesis throughout life stage
decreases
0-18 years what you need to take into consideration when measuring the dri for protein
nitrogen losses and growth
