NUTR-313 Final: Lecture 33 (Nutrition for
Ages) Exam Questions and Answers
(Latest 2026)
Life Groups - Correct Answers ✅We're going to talk in this
part about the nutritional needs across the life stages. And,
so far, we've talked about the adult daily nutrient
requirements. So, anyone in the age range of 18 all the way
to 50 which covers most of us in this class. But now, we're
going to learn about the nutrient needs and how they deviate
for different ages that are younger and older than the general
18 to 50 year old adult population. So, the way that the DRI is
sectioned into age demographics looks at infants in the
younger and older infant categories, several groups of
children all the way from toddler to teens, and then they
break off into older adults which is anywhere from 51 to 70 or
elderly adults which are anywhere from 70 plus. So, those are
the different ages we're going to look at. And the nutrient
requirements increase and decrease across these age groups
based on several factors that we will discuss.
Control: Biological and Behavioral Needs - Correct Answers
✅So, we'll start off, logically, with the youngest age group.
1.) The daily recommended intake for young infants is
actually only an adequate intake. So again, if you remember,
that's just where we measure how much is typically
consumed and that amount seems to be good to produce
general healthy outcomes
→ So, the DRI based on adequate intake is based on a certain
quantity of breast milk. And, that happens to be .67 liters.
→ So, what they do is take .67 liters of breast milk, measure
the nutrient content in that breast milk, and say that okay

this daily amount must be adequate for nutrient healthy
outcomes.
2.) So, macronutrients, micronutrients on the right, a couple
of things to look at, looking at the fat intake. So, infant fat
requirements are actually much higher than regular adults
like we've talked about so far and, you'll notice that, of
anywhere from about 500 to 600 calories that infants
consume per day in breast milk or formula, about half of
those calories are coming from fat, which is a lot higher. So,
50% calorie fat diet, fat calorie diet is much higher than the
healthy adult recommendation
3.) It's also going to be a little bit protein despite the rapid
growth rate because protein is one of the harder nutrients for
infants to digest. So, because of that, human breast milk is
very high in essential amino acids so that infants can have
less protein but still meet those essential amino acid
requirements.
4.) You'll also notice the fluid amount in breast milk and then
it's mostly, obviously, fluids, mostly water and then, you can
look over at the micronutrient side and notice a couple
interesting things like iron and zinc.
→ So, you'll notice that, iron and zinc, the DRI's much lower.
And, you know, that makes sense as a function of the size of
the baby being smaller. But really, the reason the iron co
Adequate Intake 7-12 Months - Correct Answers ✅So, the
RDA for 7 to 12 month old infants, we have a couple good
values with an actual, you know, EAR which has been

(Latest 2026)
converted to an RDA, we talked about that a long time ago.
But, a couple good sets of nutrients where they've been
measured using balanced data and standardized equations.
So, if you look at total energy or calories, it's basically using
the same kind of formulas that we've covered for healthy
adults, and protein, iron, and zinc using balanced studies
where we looked at the exact amount consumed in the diet
and then all of the different sources of losses that we sum
together. And then, from that, kind of collectively seeing how
much the body's retaining and using:
1.) So, for those, those nutrients that are listed, we have
good RDAs for 7 to 12 month old babies.
2.) For the other lots of nutrients that are listed, we have little
bit less good estimates of how much is needed daily. But,
these amounts presented seem to be producing healthy
children.
3.) So, adequate intake for 7 to 12 months old are based on
several different methods.
→ One method looks at hey we know these guys are still
consuming lots of milk, so we're going to reduce the breast
milk intake from that .67 liters and we're going to take that
down to .60 because, breast milk consumption drops off a
little bit or formula and they start having a compensatory
intake of whole foods
⤷ So, milk intake goes down to .6 liters, compensatory foods
bumps up to an estimated 400 calories per day from a variety
of different types of foods. And, from estimating those
