Students will be introduced to the concepts of calories, recommended servings, portions, and serving size. A short walk-jog-sprint demonstration will illustrate calories as a measurement of food energy consumed by the body and physical energy exerted by the body, with excess energy being stored by the body. Students will learn the difference between foods that have empty calories and those whose calories provide nutritional benefit. Students will explore recommended servings for each food group based on their age and activity level, then compare the portion vs. recommended serving sizes on a variety of foods by calculating the total number of recommended servings and calories in each portion. Students will use this information to build their awareness of portion distortion and make healthy food choices.
