How better to promote a healthy lifestyle than to get an entire middle school involved in analyzing dietary information? This article describes a series of activities that was part of an interdisciplinary schoolwide effort to discuss healthy food choices. Mathematics teachers chose to focus on students' dietary habits and, over several days, engaged more than 400 sixth-, seventh-, and eighth-grade students in exploring the U.S. Department of Agriculture's (USDA) Choose My Plate program. The dietary guidelines illustrated on the USDA's Choose My Plate diagram can provide healthy portions of data analysis, health education, and cultural responsiveness.
