Macronutrient Analysis

<< Back to All

    Why is food important to our bodies? In this data-rich lesson, students will learn about macronutrients and why our bodies need them. Students begin by recording their personal daily food intake and analyzing their own macronutrient consumption according to US standards. Students then compare macronutrient consumption profiles of teenagers from different countries. The two parts can be done in sequence or independently.
