Dietary Reference Intakes
(DRI)
.
Dietary reference intakes are used
to plan and evaluate diets for
healthy people
Establishing Nutrient
Recommendations
1. Estimated Average Requirement (EAR) defines the
requirement of a nutrient that supports a specific function
in the body for half of the healthy population.
2. Recommended Dietary Allowances (RDA) use the EAR
as a base and include sufficient daily amounts of nutrients to
meet the known nutrient needs of practically all healthy
populations. This recommendation considers deficiencies.
3. Adequate Intakes (AI) reflect the average daily amount of
a nutrient without an established RDA that appears to be
sufficient.
4. Tolerable Upper Intake Level (UL) is a maximum daily
amount of a nutrient that appears safe for most healthy
people and beyond which there is an increased risk of
adverse health effects.
Diet-Planning Principles
Adequacy (dietary)—providing sufficient energy and
essential nutrients for healthy people
2. Balance (dietary)—consuming the right proportion of
foods
3. kcalorie (energy) control—balancing the amount of
foods and energy to sustain physical activities and
metabolic needs
4. Nutrient density—measuring the nutrient content of
a food relative to its energy content
a. Empty-kcalorie foods denote foods that contribute
energy but lack nutrients.
5. Moderation (dietary)—providing enough but not too
much of a food or nutrient
6. Variety (dietary)—eating a wide selection of foods
within and among the major food groups

Dietary Guidelines for
Americans
1. Adequate nutrients within energy
needs
a. Consume foods from all food groups
and limit foods that can be detrimental
to health.
b. Consume a balanced diet.
2. Weight management
a. Maintain a healthy body weight.
b. Prevention of weight gain
Dietary Guidelines for
Americans
3. Physical activity
a. Increase energy expenditure and
decrease sedentary activities.
b. Include cardiovascular conditioning,
stretching, and resistance exercises.
4. Food groups to encourage
a. Choose a variety of fruits, vegetables,
milk and milk products, and whole
grains.
Dietary Guidelines for
Americans
5. Fats
a. Limit saturated fat, dietary cholesterol, and
trans fats.
b. Choose monounsaturated and polyunsaturated
fat sources.
c.Choose lean, low-fat, or fat-free foods.
6. Carbohydrates
a. Choose those that are high in fiber.
b. Choose products with a minimal amount of
added sugar.
c.Decrease the risk of dental caries.
Dietary Guidelines for
Americans
7.Sodium and potassium
a.Choose foods that are low in salt and high in
potassium.
8.Alcoholic beverages
a.Drink in moderation.
b.Some should not consume alcohol.
9.Food safety
a.Wash and cook foods thoroughly and keep cooking
surfaces clean.
b.Avoid raw, undercooked, or unpasteurized products.
Exchange Lists
Exchange Lists help to achieve kcalorie
control and moderation.
1.Foods are sorted by energynutrient content.
2.Originally developed for those
with diabetes
3.Portion sizes vary within a group
4.Food groupings may not be logical
"Planning a Healthy
Diet"
The name, slogan,
and website present
a personalized
approach.
The multiple colors of the pyramid
illustrate variety: each color represents
one of the five food groups, plus one
for oils. Different widths of colors
suggest the proportional contribution
of each food group to a healthy diet.
A person climbing
steps reminds
consumers to be
physically active
each day.
The narrow slivers
of color at the top
imply moderation in
foods rich in solid
fats and added
sugars.
The wide bottom
represents nutrientdense foods that
should make up the
bulk of the diet.
Greater intakes of
grains, vegetables,
fruits, and milk are
encouraged by the
width of orange,
green, red, and
blue, respectively.

Plan Meals thru the Day
Think about what you are going to
eat instead of eating by habit or
impulse!
Eat more earlier when more active
Eat less later when less active
i.e. a little often vs. a lot at once
Plan Meals thru the Day
Most (about 85%) 0f the calories
people consume are by habit or
impulse
Most (about 65%) of the calories
people consume are in the latter day

Eat a Variety of Foods
(at Each Meal)
Provides more nutrition
Each member of the family can
choose what they want at that time
Controls eating one food in excess
Exposes a person to different foods
Makes a better meal

Carbohydrate Foods
Answers the question
“What am I supposed to eat”?
Provides the best source of energy.
Provides a lot of most nutrients,
(including fiber)
Low in fat, and has the ‘good’ type
and contains no cholesterol.
Most have protein, certainly enough.
Are not fattening--fats are!
Minimize FATS and SUGAR
Fats are fattening
Fats can lead to other health problems
‘Minimize’ fat intake, don’t eliminate it
Sugar in large amounts is a problem
Sugar is an enjoyable taste and may
displace foods with more nutrition and
be concentrated
Fat and Sugar mix well with each other:
the real problem
“you’re eating too much sugar.”
Your fired, Jack.
Your lab results just came back,
and you tested positive for Coke
‘WHAT CAN I DO ABOUT
THESE BAD HANGOVERS
I GET, DOCTOR’?
‘YOU CAN STOP
DRINKING ALCOHOLIC
BEVERAGES’!
“NO SERIOUSLY, WHAT CAN I DO”?
Don’t worry about
PROTEINS
Important for growth (height) and
development
Needed in smaller amount than most
people think (.8 grams/kilogram BW)
Can be gotten from a variety of
carbohydrate foods as well as the
protein foods (meat, dairy)
Use as a part of the meal, not as the
meal (eat lean, less and last)
Thought of the day
Give a man a fish and
he will eat for a day.
Teach him how to fish, and
he will sit in a boat and
drink beer all day.

nothing”
Physical Activity
Include:
cardiovascular conditioning,
stretching,
resistance exercises or
calisthenics for muscle strength
and endurance
Three more, two more, one more,
okay!...Five million leg lifts right
leg first! Ready
“the only stretching Leroy
does is when he yawns”
I see no reason
why you should not
engage in
strenuous activity
Physical Activity
Engage in regular physical
activity and reduce sedentary
activities to promote health,
psychological well-being, and
healthy body weight
…
Physical Activity
Weight management – 60+ minutes
of above while not exceeding intake
requirement
Sustain weight loss – 60 to 90
minutes of above
…
Reduce risk of chronic disease in
adulthood by doing 30+ minutes of
moderate-intensity physical activity,
above usual activity, at work or home
on most days of week
