Communication Objectives
• This lecture intends to:– Define “nutrients” and “nutrition”– Help students discover the difference
between appetite and hunger– Discuss issues that affect the foods you
choose to eat
Nutrients
• The substances in food that your body needs to function properly to grow, to repair itself, and to supply you with energy.
• Nutrients come from the foods that you eat, and affect all aspects of your life.
Hunger
• The body’s physical need for food. • A natural drive that protects you
from starvation. • Nerve endings in your stomach tell
your brain that your stomach is empty and needs food.
• Eating satisfies this need.
Appetite
• A desire to eat, rather than a need.• A learned response shaped by your
environment. – Cultural heritage– Family and Friends– Media Messages– Lifestyle
Culture
• Food choices are made based on our:– Culture– Ethnic background– Religious beliefs– Age group
Family and Friends
• What you grew up eating with your family shaped your likes and dislikes in regards to food, and will affect your eating choices throughout your life.
• New food experiences at friends’ houses introduced you to new foods that you may have liked or disliked.
Advertising
• Advertisements about food are in television, magazines, and on the internet
• Ads attempt to influence you to try a certain food, and hopefully continue to buy it.
• Ads should be reviewed cautiously, because many are persuasive but misleading.
Time, Money, and Your Emotions
• People choose foods that are quick, easy, and cheap
• People may eat more or less when they are bored, stressed, frustrated, depressed, upset, or tense
Your Eating Habits
• Eating poorly can result in many undesirable health conditions.

• People do not know the difference between being hungry and having an appetite, so they eat past the point of being full.
