Procedures
1. Begin the lesson by asking students for their ideas about healthful eating. Write their ideas on a sheet of newsprint.
2. Share with the class the latest dietary recommendations from USDA, which can be found at http://www.hhs.gov/news/press/2005pres/20050112.html. To help facilitate the discussion, here are some of the key points in the recommendations:
3. Tell students that eating healthily should also be fun and interesting. Then explain to them that they will have an opportunity to gain more control over what they eat by working with their classmates to develop a class cookbook.
4. Divide students into groups of three or four. Tell each group to look at recipes either online or in magazines and cookbooks and to find at least five recipes — one for breakfast, one for lunch, and lunch and two for dinner, as well as a recipe for a side dish or dessert. The recipes must be appealing and have healthy ingredients. Students may find the following Web sites a good place to start.
5. Give students time in class to look for recipes. If students have not found at least five recipes, they should complete the assignment for homework. Tell students to make sure that they bring to class a hard copy of each recipe.
6. During the next class period, collect the recipes and organize them by meal and/or category into a class cookbook. Make a copy for each student in the class.
7. If students would like, each group can make a cover for the cookbooks. Then go over the recipes and pick out class favorites. Suggest that students prepare at least one recipe for their families or friends.
Evaluation
Use the following three-point rubric to evaluate students' work during this lesson.
Vocabulary
carbohydrate
Definition:An organic compound found in the form of starch, sugar, or fiber; one of the three basic food types and a major source of dietary energy
Context:While scientists have debated how many carbohydrates should be eaten each day, most agree that they are an important part of a healthy diet.
cholesterol
Definition:A waxy, fat-like substance produced by the liver and found in foods from animal sources; it also is an important chemical found in cell membranes
Context:Our bodies need cholesterol, but too much of this substance can build up on the walls of the arteries, leading to heart disease.
diet
Definition:The types and amount of food eaten each day
Context:Eating a balanced diet means selecting the recommended number of servings of foods from each of the three main food groups-proteins, carbohydrates, and fats-each day.
fat
Definition:High-energy nutrients that contain twice as much energy as an equal amount of carbohydrates; one of the three basic food types
Context:While foods high in fat taste good and can fill you up, they also contain a lot of calories and can lead to significant weight gain.
food
Definition:The fuel that gives the body the energy it needs to perform all needed functions and to stay alive.
Context:Eating a variety of foods is good for your body-and also creates an interesting diet.
protein
Definition:A naturally occurring substance made of amino acids and found in animal products and some plant products; one of the three basic food types
Context:Our bones and teeth need protein, which is found in meats, fish, egg whites, nuts, and grains.
saturated fats
Definition:Fats that are usually solid at room temperature.
Context:Saturated fats, which are found in vegetable shortening and margarine, tend to increase a person's blood cholesterol level.
trans fats
Definition:Created by turning unsaturated fats into saturated by fats through a process called hydrogenation
Context:Trans fats are used in many processed foods because they improve the food's shelf life, but they all raise blood cholesterol levels.
unsaturated fats
Definition:Fats that are usually liquid at room temperature.
Context:Unsaturated fats, such as olive oil and peanut oil, come from plants and tend to decrease a person's blood cholesterol level.
