The teacher told me that during the times of hyper-inflation and acute food shortages in Zimbabwe, their students had difficulties learning. Hunger sapped their energy and ability to concentrate in class. Many just did not bother coming to school. Once the school began a free feeding program, the teachers could see a marked difference in their students’ performance. Today, the students receive a daily cup of a high energy drink that teachers say has turned the school around. It costs $1 per month per child.
