To meet your nutritional needs, to satisfy your
appetite, and to supply your body with
energy.
Hunger- A feeling of physical discomfort
caused by your body’s need for nutrients.
Appetite- Desire for food based on
emotional factors or other factors than
nutritional need.
Basal Metabolic Rate (BMR)
The rate at which you use energy when your body
is at rest.
Basal Metabolism is the minimum amount of
energy required to maintain the life processes in a
body (Basil Metabolic Rate = BMR)
Approximate BMR can be found using this equation:
[Your weight + zero at the end] +100 =
Approximate BMR

nutritional facts, nutrient health claims,
daily values and freshness dates.

Daily Values (From FDA)
A portion, or
percentage of our
total calorie needs
in a day
Based on a 2,000
Calorie Diet per
day
Derived from RDAs
and other sources
Not everyone
needs 2,000 kcals
per day!
•
According to the Dietary
Guidelines for Americans, the
recommended macronutrient
intake ranges are:
• Carbs: 45-65%
• Fat: 20-35%
• Protein: 10-30%
What do We Need?
The Recommended Dietary
Allowances (RDA’s) were first
published in 1943 to help
avoid deficiency
Ranges: AI = Adequate
Intake, UL= Upper Limit
The DRIs are the new “RDAs”
“Daily Recommended
Intake”
Include deficiency
prevention, chronic
disease risk reduction,
and health promotion
They are standardized by The
FDA (Food and Drug
Administration)
Pellagra, a B vitamin
Deficiency, c. 1920
Open Dates
Gives you an idea of how long food will be
fresh and safe to eat.
“Sell-by”- the last date the product can be
sold. You can still use the product after the
sell-by date.
“Best-if-used-by”- how long the product will
be at peak quality.
“Do-not-use-after”- Expiration date. The last
date you should consume the product.
Reading A Food Label
Look at the Daily Values Percentages (%DV)
Look for Fiber, Vitamins, MineralsNote the number of calories in one serving.
Daily Calorie Needs Depend on:
• AGE
• SEX
• WEIGHT

• ACTIVITY LEVEL
• Pregnancy Status
USDA Certified Organic
100% organic or
“organic” (at least 95%)
Produced without:
Hormones
Genetic modification
Antibiotics
Germ-killing radiation
Herbicides
Insecticides
Chemical fertilizers
Enriched and Fortified Foods
"Enriching" means
adding back nutrients
that were lost during
food processing.
For example, B
vitamins, lost when
wheat if refined, are
added back to white
flour.
"Fortified" means adding
nutrients that weren’t
present in the food to
begin with.
For example, milk is
fortified with vitamin D to
help your body absorb
milk’s calcium and
phosphorus.
