Why You Eat What You Do… Several influences affect eating
choices People around you
Family: What you ate growing up Friends: Restaurants and “fad” foods
Culture Connection Culture is the shared beliefs, values and
behavior of a group of people Where your live, your ethnicity, food traditions
Continued Subgroups of culture
Geography, heritage (ethnic groups), and religion Food customs
How food is prepared, served, and eaten Unique foods (BBQ from Texas, Clam Chowder from New
England) Dietary Laws
Example: Jewish religion and a Kosher Diet
Cultural Etiquette Chopsticks, eating with the hands, etc
Special Occasions “Thanksgiving” Food”, Wedding Cakes, New Year’s Day
(Black Eyed Peas and Collard Greens)
Continued… Available Food Supply
What is grown where you live Georgia is famous for what things?
Peaches, peanuts, blueberries, corn, soybeans, watermelon, onions
Technology has made an impact on how food supplies are stored and processed
Schedules, Energy, Budget What you eat and buy are affected by your
resources Time, income level, personal energy, convenience foods
(foods that are quick to prepare or eat)
Continued… You
Your lifestyle and characteristics affect food choices
Examples Age: Teenagers are not apt to eat the same foods
that adults do Attitudes/Emotions: Feelings towards foods
(memories or experiences) Diet goals and health concerns Knowledge/level of education: New recipes, products
and information can influence what you eat Income Level: Better quality foods cost more Exposure: Traveling, making new friends, trying new
cusine
Continued… Food Advertising
Ads make you aware of new foods and may provide useful information about nutrition
Can you guess these food ads? Cereal (A Tiger) Fast Food (A Dog) Bread (Whoo Hoo)
Food packaging also plays a major role in why we buy and eat the foods we do Food stylists create food products for photographs used in
advertising They also use non food items to give the idea of fresh, tasty food For example, hamburger buns are really foam spray painted and
milk is really sour cream
PROJECT! Create a food advertisement for a BRAND NEW
FOOD Must list:
Price Slogan What it is FIVE things that make it great Picture
MUST BE CREATIVE! Remember to include what you have just learned
about: The factors that affect food choices! You will be graded on all of the above,
neatness, creativity, and timeliness
What Do You Think? How might decisions about what you
eat be influenced by where you live? What else can influence food choices? Give an example of how a particular
lifestyle can affect food choices. Define media. How does the media
affect food choices? List three foods you buy because of the packaging.
Continued… Sensory Attributes
Our five senses also affect our food choices The way your senses respond to food
affect your appetite (psychological desire to eat)
Just slight aroma, taste, or seeing your favorite food can make you hungry
Sound can also affect appetite
What do you think?
You have five senses: Taste, touch, sound, sight and smell List each sense and TWO foods that appeal to
you for that particular sense What makes certain foods so appealing to
you? What are some foods that trigger your
appetite? Why do you think that some foods don’t
satisfy your hunger?
Continued…
Your tongue is covered with papillae (puh-pih-lee), or tiny bumps that contain taste buds Each papilla has hundreds of taste buds, which
distinguish sweet, sour, salty, and bitter tastes Other nerve endings sense temperature and texture
When one of your senses is altered, the flavor of food may be altered as well Illness and medications can dull sensations and
detract from the flavor of food When you have a cold and you can’t smell, it alters the
taste of food
Sense Activities Taste Test Smell Test
Special Diets and Health Concerns Only a doctor or a
health professional should recommend a medical diet Once a medical diet
has been set in place, it is important to follow it as close as possible
The most common medical diet is probably a diabetic diet
Diabetes A condition in which the body can’t
control levels of sugar in the blood properly It all has to do with insulin, which is a
body chemical that helps sugar in your blood move into your body’s cells In one type of diabetes, the body doesn’t
produce enough insulin In another, the body doesn’t use the insulin
that is produced normally Oral medicine or insulin injections may
be necessary A special diet low in sugars is required Those who are overweight are at high
risk for developing diabetes
Modified Diet A special eating plan
that helps to keep a medical condition under control
It may involve limiting certain foods or choosing foods for nutritional value
Examples Low fat/low
cholesterol Low sodium High fiber Soft diet
Food Additives These are used to improve flavor or
appearance Common examples include preservatives,
food colorings, flavorings, sweeteners, etc. Food additives can serve valuable
purposes in the production of food, but if used in excess, they may pose risk to health A common belief is that food colorings
(specifically red and yellow) can add to the effects of ADHD
Food Intolerance The body has trouble digesting or handling a
component of food Examples:
Gluten People can’t digest this protein found in wheat
products Lactose Intolerance
The inability to adequately digest lactose, the main sugar found in milk and milk products
Symptoms include diarrhea, stomach pains and nausea People will need to:
drink 1 cup of milk or less with other foods Eat hard aged cheeses (parmesan) and yogurt Choose lactose free products or use the drops that reduce
lactose Ask your doctor for a prescriptive supplement that will help
you digest lactose
Food Allergies A sensitivity to a food that involves
the body’s immune system The immune system mistakenly reacts to
the food as if it were an illness to fight Reactions include rashes, vomiting, stomach
cramps, breathing problems The reactions usually occur right after eating the
food, or just by being around them If you think you have a food allergy, there
are many types of tests your doctor can perform on you The allergy is treated by preventing the
reaction and eliminating foods from your diet that cause the reaction
Food and Medications They can affect each
other and your body’s chemistry
Food can help or hinder your body’s use of medicines
Also, some medicines affect how your body uses nutrients
Follow instructions for taking medicines, especially when they say to take with food or drink
If medicine is taken on an empty stomach, it can slow the absorption or cause ulcers
Some foods will react with medications
Organic Foods Organic foods have become very popular over
the last decade Many people chose organic because of the way
that food is grown and harvested Organic foods do not use chemical fertilizers or
pesticides Some people feel that these cause cancers and
diseases, as well as harm the environment These foods must be stamped with the USDA seal of
approval for organic food
These foods have not been proven more nutritious than conventional farmed foods
Organic foods are more costly
