3. WHY DO YOU EAT?
You eat to provide your body with
nutrients
Nutrients are substances in food that
your body needs to function properly to
grow, to repair itself, and to supply you
with energy
Eating habits stem from a physical need
for food and a psychological desire for
food
4. PHYSICAL NEED FOR FOOD
The most basic reason for eating is physical
Hunger is a natural drive that protects you from
starvation
When your stomach is empty, its walls
contract, stimulating nerve endings
The nerve endings signal your brain that your
body’s food supply needs replenishing
Once you’ve responded to this message the
walls of the stomach are stretched and the
nerve endings are no longer stimulated
5. YOUR MIND’S DESIRE FOR FOOD
Have you ever eaten something when you
weren’t necessarily hungry?
This is not a response to hunger but to
appetite
Appetite is desire, rather than a need, to
eat
6. YOUR ENVIRONMENT
There are a number of environmental factors
that influence your food choices
These include your cultural heritage, your
family and social relationships, media
messages and your lifestyle
1. Culture
2. Family and friends
3. Advertising
4. Time and money
7. YOUR EMOTIONS
Eating to relieve tension or
boredom can result in overeating
If you lose your appetite when
you are upset or bored, you may
miss out on getting important
nutrients food provides
8. YOUR EATING HABITS
Choosing foods that taste good and
provide nutrients without too much fat,
cholesterol, and sodium, is one of the most
healthful ways to reduce major risk factors
for chronic disease
Including: obesity, high blood pressure, and
high blood cholesterol
Eating is linked to six out of ten leading
causes of death in the United States
(including heart disease, stroke and cancer)
9. MEDIA & FOOD
The average child sees more than 20,000
commercials each year
By age 21, the average viewer will have
seen 1 million TV commercials
Nine out of 10 food ads on Saturday
morning are for sugary cereals, candy, salty
snacks, fatty foods and other junk food
10. NUTRITION THROUGHOUT YOUR LIFE
At every stage in life good nutrition is
essential for health
Nutrition is the process by which the body
takes in and uses food
