CHICAGO — Could protein-based snacks such as hard-boiled eggs lead to improved classroom behavior? That could be the case, according to a group of educators in one Iowa school district. Jennifer Best, Extension educator at Iowa State University Extension and Outreach, worked closely with school staff to test that theory on a small scale. Together they developed and launched a pilot project during the 2015-2016 school year called the “Protein Intervention.”
The Protein Intervention pilot project substituted protein-based snacks, such as hard-boiled eggs, string cheese or yogurt, for the carbohydrate snacks typically given to students visiting. . .
