A Healthy Diet
● To “consume a variety of foods balanced by a
moderate intake of each food”
◆Variety-choose different foods
◆Balanced-select foods from the major food groups
◆Moderation-plan your intake
Trang 408/23/21 FCNS 201 4
Status of Nutritional Health
● Desirable
● Undernutrition
◆Depleted nutrient stores
◆Reduced biochemical functions
◆Clinical signs and symptoms
Trang 6DIET PLANNING WITH THE FOOD GUIDE PYRAMIDE
● Foods are organized by their nutrients and
origins to provide patterns of intake
● Provides a visual image to convey the basics of planning a diet adequate in nutrients
● Provides the framework that ensure adequacy and balance
● Does not address calorie control, moderation,
and variety
Trang 7Not a food group-use sparingly
2-3 servings Meats
1 serving = 2-3 oz meat, fish, poultry
2 eggs, 1 1/2c cooked legumes
Trang 808/23/21 FCNS 201 8
The Food Guide Pyramid
● Not for children under the age of 2
● Each food is deficient in at least one
essential nutrient
● Variety is key
● Calorie and nutrient content may vary
within a food group
Trang 908/23/21 FCNS 201 9
Recommendations With Using the
Food Guide Pyramid
● Choose low-fat options
● Include vegetable protein several times a week
● Include dark green/yellow/orange
vegetable every day
● Include a vitamin C rich food every day
● Choose whole grains
Trang 1008/23/21 FCNS 201 10
Evaluation of Our Diet Using the
Food Guide Pyramid
● Do not meet all the serving recommendations for all food groups
● Consume 1-2 servings of fruit a day (versus
recommended 2-4)
● Consume 2-3 servings of vegetables a day
(versus recommended 3-5)
● Excessive intake in the fats, oils, and sweets
group (versus use “sparingly”)

Trang 15● Build a Healthy Base
◆Let the pyramid guide your food choices
◆Choose a variety of grains daily-whole grains!
◆Choose a variety of fruits and vegetables daily
◆Keep foods safe to eat
Trang 16The Dietary Guidelines
● Choose Sensibly
◆Choose a diet that is low in
saturate fat & cholesterol and
moderate in total fat
◆Choose beverages and foods to
moderate you intake of sugars
◆Choose and prepare foods with
less salt
◆If you drink alcoholic
beverages, do so in moderation

Dietary Reference Intake
(DRI)
● New nutrient recommendations
● Nutrient recommendations to prevent chronic diseases
● DRI for Calcium, vitamin D, phosphorus,
magnesium, fluoride
● In the plans for B vitamins, antioxidants,
macronutrients, trace elements, electrolytes, water
Trang 1808/23/21 FCNS 201 18
Standards for the DRI
● RDAs
● Adequate Intake (AI)
● Tolerable Upper Intake Levels (UL’s)
Trang 2008/23/21 FCNS 201 20
RDA
● RDA for only 19 of the important nutrients
● RDA for healthy males and females of
various age groups
● RDA for pregnant and lactating women
Trang 2108/23/21 FCNS 201 21
Uses for RDAs
● Planning food supplies for groups
● Establishing standards for food assistance programs
● Evaluating dietary survey data
● Develop food & nutrition information
● Help establish food label standards
● Regulate food fortification
● Developing new food products
Trang 22RDA FOR ENERGY:
● Different than the other allowances because it is set to discourage over consumption of food energy
● Energy RDA’s based on each person’s:
◆ age group for:
❏Infants
❏Children
◆gender for everyone over 11 years old
◆Kcal needed per kg of body weight
Trang 2308/23/21 FCNS 201 23
Adequate Dietary Intake (AI)
●Set of nutrient with insufficient research data to set specific amounts
●Based on observed or experimentally
determined estimates
●Set for some vitamins, choline, some minerals
●Planned for children under the age of 1
Trang 24◆Chronic daily use
◆Not a goal, but a ceiling
❏Applies to some vitamins and some minerals See the back covers of the text for a listing
Trang 2508/23/21 FCNS 201 25
ESTIMATED MINIMUM
REQUIREMENTS FOR:
Need at least the recommended minimum amount
of these nutrients daily, as listed by age:
● Sodium
● Potassium
● Chloride
Trang 2608/23/21 FCNS 201 26
Standards For Food Labeling
● RDA not used on food label since it is
gender and age specific
Trang 27● Covers the minimum requirements for all people, using the
group with the highest need as the base amount.
Trang 2808/23/21 FCNS 201 28
What’s on the Food Label?
● Product name
● Manufacturer’s name and address
● Uniform serving size
● Amount in the package
● Ingredients in descending order by weight
Trang 3008/23/21 FCNS 201 30
Which Food Requires a
Label?
● Nearly all packaged foods and
processed meat products
● Fresh fruit, vegetable, raw single
ingredient meal, poultry, fish are
voluntary
Trang 3108/23/21 FCNS 201 31
Which Food Do Not Require a
Label?
● Food for immediate consumption
● Ready-to-eat foods not for immediate
consumption but prepared on site
● Bulk food sold to consumer
● Medical foods
● Foods that contain very little nutrient
● Food produced by small businesses
● Food packaged in small containers
Trang 32Nutrition Facts ( Fig 2-2)
● Uniform serving size
● % Daily Value
● Based on 2,000 kcals diet
● Comparative and absolute
nutrition claim must
follow strict legal
guidelines
● Limited health claims

NUTRIENT LABEL
CLAIMS
● Low calorie = 40 calories or less
● reduced calorie = 25% lower in calories than the “regular” food
● Low Fat = less than 3 grams of fat
● Fat Free = less than 5 grams of fat per serving
Trang 3808/23/21 FCNS 201 38
NUTRIENT DENSITY
● A measure of nutrients provided per calorie of
food
◆the higher the nutrient per calorie ratio, the
more nutrient dense the food is.
❏Skim milk vs vanilla ice cream
❏oatmeal vs oatmeal cookies
❏fresh peach vs peach pie
♦ most of the time, the less processed the food, the more nutrient dense it is (whole vs partitioned foods)

TRUE OR FALSE?
● On average, one should try to get 100% or
more of the RDA for every nutrient to ensure
an adequate intake over time.
● Nutrient contents of packaged foods are stated
on food labels as Dietary Reference Intakes.
Trang 44◆ A It is safe to consume in any amount
◆ B insufficient data exist to establish a value
◆ C the committee has yet to complete its work for that nutrient
◆ D A and B
◆ E B and C

CHOOSE THE BEST
ANSWER
● The major drawback of the Food
Guide Pyramid is that:
◆A It is more expensive to follow than other
plans
◆B It does not limit food choices to foods low in
calories
◆C It is not simple to use
◆ D It makes shopping more difficult and time
consuming
