Nutrition
Chapter 5
Lesson 1
Pages 110-113
Lesson Objectives
Know the Importance of Good Nutrition
What Influences your Food Choices
Factors that influence your Basal
Metabolic Rate
What is Nutrition?
Nutrition- The process by which the body
takes in and uses food.
Calories- Units of heat that measure the
energy used by the body and the energy
that food supply to the body.
Nutrients- Substances in food that your
body needs to grow, to repair itself, and to
supply you with energy
Product Labeling
Light or Lite
Less
The calories have been reduced by at least
1/3, or the fat/sodium have been reduced
by 50%
The food contains 25% less of a nutrient
or calories
Free
The food contains NO or an insignificant
amount of total fat, saturated fat, trans
fat, cholesterol, sodium, sugars or calories
Product Labeling
More
High, Rich In, or Excellent Source Of
The food contains 10% more of the daily value
for a vitamin, mineral, protein or fiber
The food contains 20% or more of the daily value
for a vitamin, mineral, protein or fiber
Lean
The food is a meat, poultry, fish or shellfish
product that has less than 10 g of total fat, and
less than 4 g of saturated fat per 3 oz serving
Food Labels
It is a Law to have a food label on
every product that is intended for sale
Most food labels list the food’s
ingredients by weight, in descending
order, with the ingredient in the
greatest mount listed first.
So, what exactly is on our food labels?
NUTRITION FACT LABLES

Influences of your food choices
Hunger:
an unlearned inborn
response, is a natural
physical drive that
protects you from
starvation.
When the stomach is
empty, its walls contract,
stimulating nerve
endings. These nerves
send a message to your
brain that your body
needs food.
Appetite:
Is a desire, rather than a
need, to eat.
Many factors influence
your food choices and
eating habits, including
your emotions and a
number of factors in your
environment.
Question
What environmental issues
affect the choices you make
when it comes to food?
Environmental Issues
Family, friends & peers
Culture & Ethnic
Background
Convenience & Cost
Advertising
Do you think eating with
family and friends is better or
worse for you? Why?
Basic Good Nutrition Benefits
Growth
Prevention (Type II Diabetes, Heart
Disease, Stroke, Colon Cancer, Liver &
Kidney Disease, Osteoporosis etc.)
Appearance
Metabolism, What is it and
What does it do?
Metabolism converts the fuel in the food
we eat into the energy needed to power
everything we do.
From moving to thinking to growing.
Gaining and Losing Weight
Just as a car stores gas in the gas tank
until it is needed to fuel the engine,
the body stores calories - primarily
as fat. If you overfill a car's gas tank,
it spills over onto the pavement.
Likewise, if a person eats too many
calories, they "spill over" in the
form of excess fat on the body.
Gaining and Losing Weight
The number of calories a
person burns in a day is
affected by:
1) How much that person
exercises
2) The amount of fat and
muscle in his or her body
3) The person's Basal
Metabolic Rate (BMR).
Basal Metabolic Rate
Basal Metabolic Rate, or BMR, is a
measure of the rate at which a person's
body "burns" energy, in the form of
calories, while at rest.
BMR is the minimal amount of
calories the body needs to survive.
The BMR can play a role in a person's
tendency to gain weight.
What factors influence a
person’s BMR?
To a certain extent, a person's basal
metabolic rate is inherited
Exercising more will not only cause a person
to burn more calories directly from the extra
activity itself, but becoming more physically
fit will increase BMR as well.
People with more muscle and less fat
generally have higher BMRs.

Nutrition:
Carbohydrates
Chapter 5
Lesson 2
Pg. 114-118
Nutrients
Objective 1: Describe the functions of
the simple and complex carbohydrates
Objective 2: Describe the functions of
the six basic nutrients.
Objective 3: Identify some of the
benefits of fiber
What is a Carbohydrate?
Carbohydrates (Carbs)- The starches
and sugars found in foods.
Made up of carbon, oxygen, and hydrogen
The body’s preferred source of energy
Carbs provide, 4 calories per 1 gram
Carbohydrates
Your body uses the
energy from the carbs
everyday, for every task.
Depending on their
chemical make-up there
are 2 types;
Simple
Complex
55-60% of your daily
calories should come
from complex carbs.
Simple Carbohydrates
What are simple carbohydrates?
Also know as EMPTY CALORIES
Sugars; fructose and lactose
Found primarily in fruit and milk
Most familiar; Sucrose
Found naturally; plants
Refined to make table sugar
Sucrose is also added to manufactured foods

Corn, Bad for you? How?
Read quietly to yourself…
The vast majority of the high fructose corn syrup containing
55% fructose is used to sweeten carbonated soft drinks and
other flavored beverages. Minor amounts are used in frozen
dairy products. Essentially all foods listing “high fructose
corn syrup” as an ingredient contain the syrup with 42%
fructose. The 95% fructose corn syrup is becoming more
common in beverages, canned fruits, confectionery products
and dessert syrups.
“Now, a quarter of the 45,000 items in the average
supermarket contain processed corn, often in the
form of high-fructose corn syrup.”
That’s…11,250 products
Complex Carbohydrates
What are complex carbohydrates?
Starches
Found primarily in; whole grains, nuts, seeds, legumes
and tubers (root veggies)
Did you know?
Your body must break down complex carbs to simple
carbs before it can use them for energy
Complex Carbohydrates
The Role Of Carbohydrates
Your body converts all carbs to Glucose
A simple sugar that’s the main source of
energy for our bodies
The glucose that is not used is stored in the
liver and muscles as a starch-like substance
called; glycogen.
When your body needs more energy the
glycogen is converted back to glucose.
Excess carbs taken in and not used are
converted to body fat
Blood Sugar
When glucose is in your blood it is
utilized for energy and metabolized by
the hormone insulin
Too much sugar in your blood will
increase insulin levels and create
insensitivity.
This can, over time, cause type II
diabetes.
Healthy fasting blood sugar:
Less than 100 mg/dl
Question
What is Type II Diabetes and
how does it affect the body?
Fiber, What is it? What does it
do?
Is
an indigestible complex
carbohydrate that is found in
tough, stringy parts of vegetables,
fruits and whole grains.
Fiber helps move waste
through the digestive
system and helps prevent
against constipation.
Two Types
Soluble:
Turns to gel in water
Insoluble:
Doesn't dissolve in water
Fiber
Did you know?
That if you eat enough
fiber throughout your
life, it can help prevent
against heart disease!
It can also help control
diabetes by reducing
your blood glucose
levels
Eat between 20-35
grams of fiber a day!
Sources
Fruit
Vegetables w/edible
skins
Whole grains
Bran, cereal,
oatmeal, brown rice
Lowers Risk Factors
Improves blood glucose levels
Lowers “LDL” bad cholesterol
Reduces inflammation
Binds to potential cancer-causing agents,
helping to flush them out of the body
National Cancer Institute. (article from us
news.com)
How to get the Proper
amount of Fiber…
Start your day with a whole grain breakfast
cereal; Oatmeal!
Choose whole fruit instead of fruit juice
Eat 5 servings of fruit and vegetables a day!
Select high-fiber snacks
Popcorn (no butter), raw veggies, nuts, apples,
pears, peaches, plums (edible skin)
Activity
List the majority of the foods you eat
that are carbohydrates.
Write healthy alternative foods next to
the ones that may not be good choices.

Nutrition:
Protein
Chapter 5
Lesson 3
Analyzing Protein
Objective 1: Identify the role of
protein in your body
Objective 2: Be able to identify
where you could obtain the 9 essential
amino acids
Objective 3: Give an example of how
to make incomplete proteins complete
by combining foods
Review from Lesson 2
What are simple carbohydrates?
Sugars; glucose, fructose, lactose
Examples?
Fruits, Milk, Cake, Candy, Pop
What are complex carbohydrates?
Starches
Examples?
Whole grains, seeds, nuts, legumes, tubers
The body must break down__________
carbohydrates into ___________carbohydrates
before it can use them for energy.
Complex/simple
Protein, What is it? How does
it work?
Protein
Nutrients that help build and maintain body cells
and tissues
Made up of chains called, Amino Acids
Your body can manufacture all but 9 of the
20 different amino acids that make up
proteins.
These 9 amino acids are known as Essential
Amino Acids
So
where do we get them?
Complete Proteins
Complete Proteins
Contain adequate amounts of all nine essential
amino acids.
Found in animal products
Fish
Meat
Poultry
Eggs
Dairy
Products; milk, cheese, yogurt

Vegetarians
Do not eat meat
There is a difference between vegetarians and
vegans. What is it?
May have a challenge getting protein, so how do
they?
Eggs, Milk, Cheese, Yogurt
Beans, legumes, grains, nuts, seeds
Combining foods carefully is the key
Ex: Legumes + Grains
Ex: Nuts + Seeds
Incomplete Proteins
Incomplete Proteins
Lack one or more of the essential amino acids
Sources
Beans,
peas, nuts, and whole grains
If you were to combine peanut butter and bread,
that would give you a complete protein
You don’t have to combine the incomplete
proteins in one meal, you just need to eat
them over the course of the day!
Role of Proteins
Proteins have many functions including;
During major growth periods such as;
adolescence, puberty, & pregnancy, the body
builds new cells and tissues from the amino
acids in proteins.
Throughout your life your body replaces
damaged or worn-out cells by making new ones
from protein.
Role of Proteins
Your body also produces enzymes, hormones and
antibodies from proteins.
Proteins help supply your body with energy, even
though they are not the main source.
Proteins, like carbs, provide 4 calories per every 1
gram.
Excess protein is converted to body fat
Activity
How many grams of protein should you
have per meal and per day? Do you
feel you are getting enough or too few?
Does being active increase or decrease
protein needs? Why?
Do most people need protein
supplements? Why?

Fats/Vitamins/Minerals
Chapter 5
Lesson 4
Fats/Vitamins/Minerals
Objective 1: Compare and contrast
saturated, unsaturated and trans fatty acids
Objective 2: Understand cholesterol and
the difference between HDL and LDL
Objective 3: Identify the two types of
vitamins and their benefits
Objectives 4: Identify and explain the
benefits of minerals
Fats
Fats are a type of lipid
Lipid- A fatty substance that does not
dissolve in water
In your bloodstream they are stored as
triglycerides and cholesterol
Fats provide more than TWICE the energy
of carbs or proteins
9 calories = 1 gram
Fats
The building blocks of fats are called fatty
acids
Fatty acids that your body needs but cannot
produce are called essential fatty acids
Classified as 2 types depending on their
chemical composition
Saturated
Unsaturated
Most fats are a mixture of both types
Saturated Fatty Acids
Saturated fatty acids hold all the
hydrogen atoms they can, meaning
they are solid at room temperature
Examples: Animal fats/tropical oils
Palm
oil, Coconut oil
Beef, pork, egg yolks, and dairy foods are
higher in saturated fat than chicken and fish.
High
intake of saturated fat =
increased risk of heart disease
Unsaturated Fatty Acids
Unsaturated fatty acids have at least 1
unsaturated bond, meaning they have
room to add hydrogen.
Examples: Vegetable fats
Olive,
canola, soybean, corn and cottonseed
oils
Typically liquids (oils) at room temperature
Increase in unsaturated fatty acids
= lower risk of heart disease
2 Types of Unsaturated Fat
Monounsaturated
Have only one
unsaturated bond
Are liquid at room
temperature
Solidify when
refrigerated
Examples
Olive Oil
Canola Oil
Polyunsaturated
Have more than one
unsaturated bond
Liquid at room temp
and in the
refrigerator
Examples
Safflower Oil
Corn Oil
Trans-Fats/ Hydrogenated
Oils
Trans fatty Acids
Trans fats (or trans fatty acids) are created in an
industrial process that adds hydrogen to liquid
vegetable oils to make them more solid. Another
name for trans fats is “partially hydrogenated
oils."
Trans
fats give foods a desirable taste and texture.
Inexpensive to produce and lasts a long time
Examples:
Fried Foods (Fries, Doughnuts, Chicken)
Baked Goods (Pie crust, cookies, crackers, margarine)
Question
Do you think trans-fats are better or
worse for you than fat found in food?
Why?
Video
Trans-Fats
http://www.youtube.com/watch?v=2S1mQYO0g68
Cholesterol
Cholesterol
A waxy lipid-like substance that circulates in
blood.
Cannot dissolve in your blood, carried by
lipoproteins
2
major types
LDL- Low Density “bad”
HDL- High Density “good”
A high intake saturated & trans fat can lead
to an increase in cholesterol
Video
Cholesterol
http://www.healthline.com/understandingcholesterol/anatomy-animations#1/bodies-in-motioncholesterol
Role of Fats
Fats are essential to transport vitamins, A,D,E, and
K in your blood.
They serve as sources of linoleic acid, an
essential fatty acid that is needed for growth and
healthy skin.
Fats add texture and flavor to foods
Help satisfy hunger longer than carbs and proteins
No more than 20-30% of your daily caloric
intake
Role of Fats
Omega 3 fatty acids found in fish oil,
eggs and seeds may help in lessening
inflammation and improving joint
health.
Good fat and HDL cholesterol aid in
reducing risks for heart disease and
improve brain function
Risks & Blood Levels
Fasting Triglyceride levels <150 mg/dl
Fasting Cholesterol levels should be
- Total <200
- LDL <100
- HDL >40
- Ratio 4:1
Activity
What is considered a healthy total
cholesterol LDL, HDL and ratio? What
are the risks of having high total
Cholesterol, LDL and Triglycerides?
Are cholesterol & triglycerides levels
controllable? How?
What changes can you make to your
diet, to decrease saturated and trans
fat? Explain…
Vitamins
Vitamins
Are compounds that help regulate many vital
body processes including;
Digestion,
nutrients.
absorption, and metabolism of other
2 types: Water or Fat soluble
Water-
Dissolve in water, and pass easily into the
blood during digestion. (figure 5.1)
Ex: Vitamins C, B1, B2, Niacin, B6, B12, Folic Acid
Fat
Absorbed, stored and transported in fat (Fig 5. 2)
Ex: Vitamins A, D, E, and K

Minerals/Water
Minerals
Substances that the body cannot manufacture but are
needed to form healthy bones and teeth.
Ex: Calcium, Phosphorus, Magnesium, Iron
Water
Vital to our everyday body function
Lubricates your joins and mucous membranes
Drink 8 cups a day
Some beverages (caffeine, juice) cause us to lose some
of the water through increased urination.
Some fruits and vegetables contain water
