Hold a class discussion about food and its importance to the human body. A good way to review this subject is to watch The Food Pyramid .
Ask students to talk about their favorite foods. In which categories do these foods belong? What kinds of nutrients do they provide? Are they healthful?
As a homework assignment, ask students to chart the foods they eat during one day, starting with the foods they have eaten on the day of the lesson. Ask students for examples of a typical breakfast, lunch, snack, and dinner. Demonstrate how to chart each meal. (For example, if a student ate cereal for breakfast, write the header "Breakfast" on the board; below it write "cereal," "milk," and anything they might put in the cereal, such as a banana.) Talk about serving sizes: If a student ate bread, how much did they eat? Write the amounts of each food eaten on the chart. Give students some time in class to chart the foods they have already eaten that day.
Returning to the lesson the following day, ask students to compare the foods they ate with those in the food pyramid. How many servings did they eat from the milk, yogurt, and cheese group? How many servings are recommended? How much bread and cereal did they eat? Does that meet the recommended amount? Students may use the food pyramid and the following Web sites to compare what they've eaten with the recommended intake: http://www.nalusda.gov/fnic/Fpyr/pmap.htm
Then group students into pairs and have them discuss what they ate and how it compares the food pyramid. Ask volunteers to what they've learned. How well did they meet the requirements of the food pyramid? How much food did they eat from the group at the top of pyramid? What can they do to make sure they eat more healthfully?
Have the pairs work together to create a healthful menu for one day that meets the guidelines in the food pyramid. They can include foods they eat as well as some foods they think would be healthful or fun to eat. Allow groups time to share their menu ideas.
