Categories
of Nutrients
Minerals
Proteins
Vitamins
Carbohydrates
The fuel you body gets the most mileage from is
carbohydrates.
carbohydrates Sugars and starches
contained in foods
Simple Carbohydrates
Complex Carbohydrates
Sugars
Starches
(fruits, milk, table sugar)
(bread, rice, pasta, beans,
vegetables)
Carbohydrates are broken down by a process called digestion
Carbohydrates
Fiber is a complex carbohydrate that cannot
be digested.
fiber Tough, stringy part of raw fruits, raw vegetables,
whole wheat, and other whole grains
Fiber helps carry wastes out of your body.
Proteins
Proteins promote healing and aid in the repair
of tissues.
proteins Nutrients that provide the building
blocks your body needs for growth
Proteins
Fish, chicken, beef, eggs, milk, beans, nuts, soy-based products
Fats
Fats carry certain vitamins in your blood stream and
help keep your skin healthy.
fats A nutrient found in fatty animal
tissue and plant oils
Eating too many fatty foods can contribute to heart
disease and obesity.
Vitamins
Vitamins help your body use other nutrients and
fight disease.
vitamins Nutrients that help regulate body functions
Foods rich in vitamins include fruits, vegetables,
some meats, and whole-grain breads.
Minerals
Like vitamins, minerals are needed in only small
amounts.
minerals Elements in foods that help your body work properly
Calcium helps build strong bones and teeth.
Iron contributes to healthy blood.
Water
Two-thirds of your body is water.
Water carries other nutrients around your body.
Water helps with digestion.
Drink when you are thirsty and with meals to help
your body get enough water.
Water
Most of the weight of these
foods is from water.

In this lesson, you will learn to
 Essential Question:
How does MyPlate help guide my decisions regarding my diet?
 Enduring Understandings:
Students will understand that MyPlate demonstrates and explains the
importance of different foods for a healthy diet.
 MyPlate
A system designed to help Americans make
healthful food choices
 Calorie Diet
A unit of heat that measures the energy
available in foods
Diet
A particular selection of food, especially as
designed or prescribed to improve a person's
physical condition or to prevent or treat a disease
In this lesson, you will learn to
 discuss how to use the USDA (United States Department of
Agriculture) Food Guidance System.
 list the names of the five food groups.
 demonstrate how to plan a nutrient-rich meal using MyPlate.
The MyPyramid Food Guidance System
The MyPlate Food Guidance was developed by
the United States Department of Agriculture
(USDA).
MyPlate A system designed to help Americans
make healthful food choices
A Closer Look at MyPlate
MyPlate is designed to help each person develop a
personal eating plan based on how many calories
he or she needs.
calorie A unit of heat that measures the
energy available in foods
The amount of calories your body needs is based on
your age, gender, and how physically active you are.
A Closer Look at MyPlate
If you are physically active on most days,
your body needs more calories than
someone who is not physically active.
MyPlate estimates that females between
the ages of 9 and thirteen need 1,600 to
2,200 calories per day based on activity
level. Males in the same age group need
1,800 to 2,600 calories per day.
A Closer Look at MyPlate
Grains—the Orange Group:
Girls should have five to seven 1-ounce equivalents of grain products each
day. Boys should have six to nine 1-ounce equivalents.
Vegetables—the Green Group:
Most boys need 2½ to 3 ½ cups of vegetables a day, girls 2 to 3 cups.
Fruits—the Red Group:
Most girls and boys should have 1½ to 2 cups from this group daily.
Dairy—the Blue Group:
Boys and girls should both have 3 cups of milk or other foods made from milk.
Protein—the Purple Group:
Most girls should have 5 to 6 ounces from the meat or beans group every day.
Most boys should have 5–6½ ounces
Nutrition - Performance Task
Your are member of a health club at school. You have
heard that many students are complaining about the health
choices at school. Your role is to analyze and critique the
existent food menu at school. You need to create a top 10
food list (not including snacks or drinks) that you would
present to your health teacher as part of a wide healthy
eating campaign at your school. You can use the computer
lab and research on MyPlate.gov or Nutritiondata.self.com
in order to complete the assignment.

Essential Question:
Why is it important to have a positive body image?
Enduring Understanding:
Students will understand that a healthy self-concept is important
to a positive body image.
 body image
How you view your body
 eating disorder Extreme eating behavior that can seriously
damage the body
In this lesson, you will learn to
 explain how to maintain a healthy weight.
 identify problem eating behaviors.
 demonstrate decision-making skills to help a friend.
Achieving a Healthful Weight
If your weight is right for your height, try and
keep it that way.
If you are concerned about your weight, talk to
your doctor.
Weight Problems and Teens
Some children and teens are becoming obese,
which means they are significantly overweight.
People who are obese are at risk for developing
diseases such a diabetes and heart disease.
Treatment for Obese Teens
Obese teens should be under a doctor’s care.
Obese teens should reach a healthy weight slowly.
The best approach is to avoid gaining weight as
your body grows.
Respect for Others’ Bodies and Feelings
Some teens tease peers who are overweight or
underweight. This type of behavior shows a lack of
respect. It is a form of bias, acting cruelly to those who
look different. A person who does this is not
demonstrating good character.
Body Image and the Teen Years
Like your self-concept, your body image
may differ from how others see you.
body image How you view your body
Comparing yourself to images from
the media can lead to a negative
body image.
Eating Disorders
People who feel they may need to lose weight
when they really don’t are at risk for developing an
eating disorder.
eating disorder An extreme eating behavior that
can seriously damage the body
Eating Disorders
Two of the most common eating disorders are
anorexia nervosa and bulimia.
Anorexia: People with anorexia are overly
concerned with weigh gain. They may starve
themselves
Bulimia: People with bulimia eat large amounts of
food, then “purge” themselves by vomiting or taking
laxatives.
Treatment for Eating Disorders
A person with an eating disorder should get help
right away.
The sooner a person gets treatment, the better his
or her chances of recovering.
