Nutrition & Eating
Disorders
Nutrition
 Study of what people eat and of eating
habits and how these affect their health
The Foods You Choose
 How do these factors influence your decisions?





Personal Preferences
Cultural Background
Time and Convenience
Friends
The Media
 Worksheet: Personal Inventory
Food Log Activity
 Create a food log by folding a paper in half
 Day & Date
 Time: List all food that you ate, including
serving size (cups, pieces, tablespoons, etc),
how it was prepared (grilled, fried, homemade,
canned or fast food), and condiments added
(salt, mustard, mayo, butter, etc)
 food diary example
 Food Log Rubric.doc
Reading a
Food Label
 Food Label
 Panel of nutrition
information required on all
processed foods regulated
by the Food and Drug
Administration
 Nutrition Facts
 Title of information panel
that is required on most
foods
Serving Size
 Serving Size: is the listing of food that is
considered a serving
 Provided in familiar units, such as cups or
pieces, followed by the metric amount, e.g.,
the number of grams
 Serving per container: listing of number of
servings in container or package
Calories
 Calories provide a measure of how much energy you get from a
serving of the food.
 Calories: number of calories in 1 serving
 The General Guide to Calories provides a general reference for
calories when you look at a Nutrition Facts label. This guide is
based on a 2,000 calorie diet.
 General Guide to Calories
 40 Calories is low
 100 Calories is moderate
 400 Calories or more is high
Look at Fat, Cholesterol,
& Sodium per serving
 % Daily Value: Based
on 2000 calorie diet
 Eating too much fat,
saturated fat, trans fat,
cholesterol, or sodium
may increase your risk of
certain chronic diseases,
like heart disease, some
cancers, or high blood
pressure.
Daily Value
 % Daily Values
 5% or less is LOW
 20% or more is HIGH
 The %DV helps you
determine if a
serving of food is
high or low in a
nutrient
Fiber, Vitamins, & Minerals
Dietary Fiber: Aim for
25g/day
Vitamins and Minerals:
Aim for 100% of DV
through a wide
variety of foods
Footnote
 The Footnote in the
lower part of the
nutrition label tells
you "%DVs are
based on a 2,000
calorie diet".
Food Labels
 Ingredients listing: list of ingredients in
a food. The ingredients are listed in order
of quantity in food, the most to least.
 Food additives: substances intentionally
added to food
 Enriched food: nutrients lost during
processing are added back into food
Food Labels:
Nutrient and Health Claims
 …Free
 Fat free: contains less than 0.5 g fat
 Sugar free: contains less than 0.5 g sugars
 Low in…
 Low in calories: contains less than 40 calories
 Low in sodium: contains less than 140 mg of sodium
 High in…
 High in Vitamin C: one serving provides 20% or
more of the DV of vitamin C
Food Labels:
Nutrient and Health Claims
 Light
 Contains 50% less fat or at least 1/3 fewer calories
then regular version of product
 Excellent source of…
 Excellent source of calcium: one serving provides
20% or more of the DV for calcium
 May reduce your risk of heart disease
 Can appear on fiber containing grain products,
fruits, and vegetables that are also low in saturated
fats and cholesterol
Nutrients
 Nutrients are substances that the body
needs to regulate bodily functions,
promote growth, repair body tissues, and
obtain energy.
 Six classes of nutrients: carbohydrates,
fats, proteins, vitamins, minerals, and
water
Energy Nutrients
 Why do we need energy?
 Your body needs energy for everything you do:
running, playing an instrument, even sleeping.
 You need energy to maintain your body temperature
and keep your heart beating
 Energy nutrients provide calories
 Energy nutrients include carbohydrates, proteins
and fats
 Calorie: unit for the amount of energy released
when nutrients are broken down
Energy Nutrients:
Carbohydrates
 Carbohydrates supply 4 calories of energy per
gram (4kcal/gram of carbohydrates)
 Recommended daily intake: 45-65% of daily
calories
 Two Types:
 Simple
 Complex
Simple & Complex
Carbohydrates
 Simple Carbohydrates
 Sugars that naturally occur in fruits, vegetables and
milk
 Added sugars to manufactured foods such as
cookies, candies, soft drinks
 Complex Carbohydrates
 Starches, found in plant foods, such as potatoes,
grains, rice, oats, corn, and wheat products
 Complex carbohydrates take longer for your body to
metabolize than simple carbohydrates
Carbohydrates
 Fiber: a type of complex carbohydrate that can
not be broken down by the body
 Fiber passes through your body without being
digested
 Benefits of a high fiber diet include
 Helps prevent constipation
 May reduce risk of colon cancer
 May help prevent heart disease
 Fiber is found in whole grain breads and
cereals, vegetables, fruits, nuts, beans and
seeds
Fats
 Fats supply your body with energy, form
your cells, maintain body temperature,
and protect your nerves.
 9 calories/gram of fat
 Recommended Daily Intake: 20-35% of
daily calories, primarily from unsaturated
fat
Fats
 Unsaturated Fat aka “Good Fat”
 Important for cardiovascular health & can help fight
heart disease
 Found in plant products
 Monounsaturated & Polyunsaturated fats
 Mono: olive oil, peanuts, and canola oil
 Poly: safflower, corn and soybean oil, and seafood
 Saturated Fats aka “Bad Fat”
 Too much can lead to cardiovascular disease
 Solid at room temperature
 Found in animal fats, lard, and dairy products
Proteins
 Proteins most important function is their role in the
growth and repair of your body’s tissues
 Great sources: meats, eggs, poultry, milk, milk
products, nuts, dried beans, dried peas, and lentils.
 4 calories/gram of protein
 Recommended Daily Intake: 10-35% of daily calories
Proteins
 Proteins are made up of amino acids
 There are 20 different amino acids; 9 are essential,
meaning you must get them in your diet, the other
11 your body can manufacture from your diet
 Complete Proteins: contain all 9 essential amino
acids
 Meats & fish
 Incomplete Proteins: Lacks 1 or more of the
essential amino acids
 Plant sources, such as beans
Vitamins
 Vitamins do not provide energy, but they
help with various processes and
chemical reactions in the body
 Fat-soluble vitamins: dissolve in fat
 Vitamins A, D, E, & K
 Occur in vegetable oils, liver, eggs and
certain vegetables
 Can be stored by the body in fat
Vitamins
 Water-soluble vitamins: dissolve in water
 Vitamin C and all B vitamins
 Occur in fruits, vegetables and other sources
 Can not be stored by the body, therefore it is
important to eat foods that supply them
every day
 Antioxidants: Help protect healthy cells
from the damage caused by normal
aging processes and certain cancers
 Vitamin C & E are most powerful antioxidants
 Berries, broccoli, tomatoes, whole grains, seeds, nuts
and peanut butter
Minerals
 Minerals do not provide energy, but they
perform a wide variety of functions within your
body and are essential for good health
 Significant amounts: Calcium, sodium,
potassium, magnesium, phosphorus, chlorine
and sulfur are need in significant amounts
 Trace amounts: Iron, fluorine, iodine, copper,
and zinc
Minerals
 Calcium
 Function: helps build and maintain bones & teeth
 Source: milk, dark leafy greens, legumes
 Potassium
 Function: helps maintain water balance and make protein
 Source: vegetables, fruits, meat, poultry and fish
 Iron
 Function: necessary for healthy red blood cells
 Source: red meat, seafood, legumes, fortified cereals
 Sodium
 Function: helps maintain water balance, heart and nerve
function
 Source: table salt, processed foods, soy sauce
Water
 About 65% of your body weight is water
 Water does not provide energy, but is essential
for all life processes, including energy
production
Water is also important because:




Makes up a basic part of blood
Helps with waste removal
Regulates body temperature
Cushions spinal cord and joints
Water
 Females, 14-18 years old: need at least
10- 8 ounce cups of water
 Males, 14-18 years old: need at least 148 ounce cups of water
 Water can be consumed in fruits,
vegetables, juices
Water
Dehydration: a serious reduction in body’s water
content
 Symptoms: weakness, rapid breathing, a weak
heart beat
 Drinks that contain caffeine-coffee, tea and
soda- contribute to the amount of water your
body excretes, so avoid these beverages
“MyPyramid Plan”
 MyPyramid Plan is based on an
individual’s age, sex, and activity level
 The pyramid includes physical activity as
an important part of staying healthy
Food Guide Pyramid
http://www.gcsnp.org/powerpoint/Food%20Guide%20Pyramid.ppt
Food Guide Pyramid
The new pyramid helps us…
 Make smart choices from every food group
 Find our balance between food and physical
activity
 Get the most nutrition out of our calories.
The New Food Guide Pyramid has
six food groups…
Grains
Vegetables
Fruits
Milk Group
Meats and Beans
Oils
• Any food made from: wheat, rice, oats,
cornmeal, barley, or other cereal grain.
• Whole grains contain the entire grain kernel.
• Refined grains have been milled, which
removes the bran and germ from the
grain.
• This improves the texture and shelf-life, but
removes the fiber, iron, and B vitamins from the
final grain product.
