Hunger versus Appetite
 Hunger
is Your body’s natural drive that protects you
from starvation.
 Appetite is a desire rather than a need for food.

influence what you eat.

How much of
each Nutrient?
Recommended
Dietary Allowances (RDAs) are the
recommended nutrient intakes that will meet the
needs of most healthy people.
RDAs are guidelines, not exact requirements.
Nutrition Label
1. Look at the serving size and servings
per container.
2. Calories(calories from fat): calories
provide a measure of how much energy
you get from a serving of food.
3. Look @ nutrients. Watch how much
saturated fats, cholesterol, and
sodium.
4. Understand the footnote @ the bottom.
5. The Percentage of Daily Value (%DV)
helps determine if a serving of food is
high or low in a nutrient.
Understanding Food Labels
Serving
Size Nutrition labels show the
size of a single serving. All other values on
the label are in reference to this serving
size.
Calories Nutrition labels list total
Calories, the Calories from fat, and the
Calories from saturated fat.
Understanding Food Labels
Daily Values
(DVs) are recommended daily
amounts of nutrients.
The percentage DV tells the amount of
the nutrient in a serving relative to the
total recommended daily amount for a
2000-Calorie diet.
Food Labels Terms
Food
labels list ingredients in order of
weight.
Food labels also typically list the amount
of cholesterol, sugars, sodium, and protein
per serving.
Ingredients List
 Almost
all food labels have an ingredients list. The
ingredient in greatest amount is labeled first.
 Food additives must be listed on food labels. They
are used to add nutrients, lengthen storage life and
keep it safe to eat, give flavor and add color, maintain
texture, help age foods (like cheese).
 Foods can be enriched (nutrients that were lost in
processing and have been added back) or fortified
(addition of nutrients that are not naturally present).
Food Labels
Food
labels will try to trick you!
Always check your serving sizes.
Serving sizes are the amount of food the
label is made for.
Foods also show how many servings are
in a package/beverage.
Food Guide Pyramid
The
Food Guide Pyramid is a visual and
conceptual tool for planning your diet.
The pyramid shows the recommended
number of servings from each of six food
groups.
Food Guide Pyramid
2000 Calories Meal
Well Balanced Meals
Write
down an example of a healthy meal
for breakfast, lunch, and dinner.
Keep in mind the food guide pyramid and
what it recommends.

Dietary Guidelines
Choose
a diet low in saturated fat and
cholesterol.
Choose food and drink to moderate sugar
intake.
Choose and prepare foods with less salt.
Adults who drink alcohol should do so in
moderation
Nutrient Density
Nutrient
density is a measure of the nutrients in
a food compared with the energy the food
provides.
Food with low nutrient density is sometimes
called junk food.
Eating junk food occasionally is OK, but you
should always aim for balance and moderation.
You can make up for the nutrients missing in
junk food by eating healthier foods at other
times of the day.
Snacks
Food
prepared at home often has less fat
and sodium than food from fast-food
restaurants.
Eating snacks can be healthy if you choose
to snack on healthier foods.
If you do eat low-nutrient snacks, make
sure to balance them out with healthy
meals.
Teen Years
During
the teen years, the body grows and
changes rapidly.
Adolescent boys should use the high end
of the serving ranges on the Food Guide
Pyramid. Adolescent girls should use the
middle of the ranges.
Teen Years
Teens
should make sure to meet nutrient
needs without exceeding energy needs.
Because adults grow less and are less
active than teens, they need fewer Calories
per day.
Adults must still make sure their nutrient
needs are met.
Athletes Dietary Needs
Athletes
must drink lots of fluids and
avoid dehydration.
Athletes need a diet high in carbohydrates
for extra energy.
Most athletes do not need extra protein
in their diets
Athletics
Athletes
do not need dietary supplements
to improve performance. In fact, these
supplements can be dangerous.
If you take a dietary supplement, do not
exceed the Tolerable Upper Intake Limit
for any nutrient
Special Dietary Needs
Pregnant
women need up to an additional 450
Calories per day.
Pregnant women also need additional protein,
B vitamins, folate, iron, and zinc.
If you have a cold, flu, or other mild illness,
drink plenty of fluids.
If you have a chronic or long-term illness, you
must make sure your diet gives you enough
energy and the proper nutrients to fight the
illness.
Vegetarian Diet
A
vegetarian diet is one in which few or no
animal products are eaten.
Vegans are vegetarians that eat no animal
products in any form.
Most vegetarians get all the proteins they need
from the small amounts of animal products they
eat.
Vegans must eat from a variety of plant sources
to get all the essential amino acids and other
important nutrients.
