  2. BELLRINGER: • How can the foods you choose affect your health? • What food did you eat most recently and why did you choose that particular food?

  3. Section 1 The Importance of Nutrition

  4. BIG IDEA • Learning to make healthful food choices will keep you healthy throughout your life.

  5. You are what you eat…. Why nutrition Matters • Nutrition – The process by which your body takes in and uses food. • Nutrients – Substances in food that your body needs to grow, to repair itself, and to supply you with energy. • THE THREE FUNCTIONS OF NUTRIENTS

  6. Calories • What is a calorie? A calorie is a unit of heat used to measure the energy your body uses and the energy it receives from food. • Calories provide the energy that your body uses to perform daily functions. From exercising to your heart beating and breathing.

  7. Importance of proper nutrition • Importance at a young age: • Provides healthy growth and development. Fuel for physical activities, mental alertness, and looking and feeling your best. Lifelong Importance: Help avoid unhealthful weight gain and disease such as type II Diabetes. Also Lower risks of cardiovascular disease, certain cancers, stroke, and osteoporosis.

  8. What Influences your Food Choices? • How do most people look at food and what they should eat? • What tastes good? • Our daily needs (food pyramid) • What our body needs for the activities we have performed (weightlifters, marathon runners, etc.) People eat for two reasons: 1. Hunger – The natural physical drive to eat, prompted by the body’s need for food. 2. Appetite – The physiological desire for food.

  9. Foods and Emotions • People eat in response to stress, frustration, loneliness, and sadness. • Some people may eat out of boredom. • Some may do “mindless eating” – snacking on chips while watching a tv show. Eating with emotions can typically lead to weight gain; however, someone who doesn’t eat because of being upset could not get the proper nutrients there body needs.

  10. Food and Your Environment • Family and Culture – If your family eats most meals at home, this will influence what you eat. You may prefer certain foods because of your family’s cultural influence. • Friends – If your friends always go for pizza after school, you’ll probably eat pizza too. Your might try new foods with friends, including foods from other cultures. • Time and Money – People with busy schedules may choose foods that are quick and easy to prepare, such as convenience foods and microwavable meals. Cost can also be a factor. For instance, you may not eat expensive steaks very often. • Advertising – Advertisers try to influence your decisions about food. They hope that an ad from a juicy hamburger will send you out to the nearest fast-food window.
