Prior to assigning this assessment I instruct students on a nutrition overview using the note sheet in the preview file and show the movie Fed Up. It is on youtube and amazon prime and is a phenomenal resource. During the unit students use myfitnesspal.com or the app to log their food intake for 5 consecutive days. The assignment then has them create a graph using that nutritional data and reflect on the experience and their insights by answering the questions. There are other caloric tracking websites but I have found this one to be the best for my students needs. They must be 18 to create a profile so check with your administrators for permission. Additionally, I require the students select nutritional goals to maintain or gain weight rather than lose weight. My philosophy is that food is fuel and our students need to fill their gas tanks with the good stuff!
