• Continuum of nutritional status
• Point of continuum
• What we eat affects our health
– Over nutrition
• Chronic consumption of more than is
necessary for good health
• Linked to leading causes of deaths in
the United States

Linking Nutrients, Foods, and Health
• Choosing a healthful diet
– Moderation
• Not taking anything to extremes
– Variety
• Include a lot of different foods in your
diet
– Balance
• Choose a variety of foods and eat a
moderate amount
Dietary guidelines:
• Improve over all health
• Many countries have developed their
own food guidelines
• Help with food choices
• Healthy population is more productive
and less strain on health care resources
Dietary Guidelines
• Dietary Guidelines for Americans (2005)
• First released in 1980
– Science-based advice
– Promote health; reduce chronic disease risk
– Recommendations encourage Americans to eat
fewer calories, be more active, and make wiser
food choices
Dietary Guidelines
• Dietary Guidelines for Americans
– Adequate nutrients within calorie needs
• Consume a variety of foods
• Eat a balanced diet
– Weight management
• Maintain weight
• Prevent gradual weight gain over time

Dietary Guidelines
• Using the Dietary Guidelines for
Americans
– Does not identify food to consume or to
avoid
– Gives advice about the overall
consumption of one’s diet
Dietary Guidelines
• Canada’s Guidelines for Healthy Eating
– Set of positive, action-oriented messages
for healthy Canadians
• Canada’s Physical Activity Guide
– Build 30–60 minutes of moderate physical
activity/day for adults
– Build 90 minutes of activity/day for children

Guide in Diet Planning (page 46)

and fat) content

– Other carbohydrates
– Vegetables
– Meats and meat substitutes

Recommendations for Nutrient
Intake: The Dietary Reference Intake
(DRIs)
• Understanding dietary standards
– Recommendations for nutrient intake
– Developed by the Food and Nutrition
Board (Canada RNI and US RDA)
– Apply to healthy people in the United
States and Canada
– Four basic elements
Dietary Reference Intakes (DRIs)
• Estimated Average
Requirement (EAR)
– Amount that meets the
nutrient requirements of
50% of people in a lifestage and gender group
– Based on functional
indicator of optimal health
Dietary Reference Intakes
• Recommended
Dietary Allowance
(RDA)
– Amount that meets
the needs of most
people in a life
stage and gender
group
Contd:
• RDA is based on the EAR
• General population can use RDA as a
target goal of dietary intake
• Remember this is a general target and
not individualized
Dietary Reference Intakes
• Adequate Intake (AI)
– Amount thought to be
adequate for most people
– AI is used when EAR and
RDA can’t be determined
• Tolerable Upper Intake Level
(UL)
– Intake above the UL can be
harmful
Dietary Reference Intakes
• Estimated Energy Requirement (EER)
– Energy intake needed for energy balance
– Determined by using weight, height, age,
and physical activity
• Acceptable Macronutrient Distribution
Range (AMDR)
– Recommended balance of energy sources
Dietary Reference Intakes
• Use of dietary standards
– Population groups (military, WIC, school)
• Assess adequacy of intake
• Plan diets
• Set policy and guidelines
– Individuals
• Use RDA and AI as target levels for
intake
• Avoid intake greater than the UL
Food Labels
• Food and drug Administration (FDA)
• 1990 Nutrition labeling and education ACT
(NLEA)
• Mandatory information on food labels
– Statement of identity
• “Appropriately descriptive term”
– Net contents of the package
– Name and address of manufacturer, packer, and
distributor
Food Labels
• Mandatory information on food labels
– List of ingredients
• Listed by common or usual name
• Listed in descending order by weight
– Nutrition information
• Nutrition Fact panel (most important
information)
Food Labels
• Nutrition Facts panel
– Standard format
Food Labels
• Daily Values
– Compare amount in one serving to amount
recommended for daily consumption
– Based on recommended amounts of 2,000
calorie diet
• Nutrient content claims
– Descriptive terms (e.g., low fat, high fiber)
– Defined by FDA
Food Labels
• Health claims
– Link one or more dietary components to
reduced risk of disease
– Must be supported by scientific evidence
– Approved by FDA
• Structure/function claims
– Describe potential effects on body structure
or function
Food Labels
• Using labels to make healthful food
choices
– Can compare
products
