When her eldest son was in elementary school in the Oakland Unified School District, Ruth Woodruff became alarmed by the meals he was being served at school. A lot of it was frozen, processed foods, packed with preservatives. So in late 2008, she and a group of parents got together to urge the school district to reconsider how and where it was buying the food it served students. Now, five years after the district responded by overhauling the menus at its 100-plus schools - serving less meat and adding more fruits and vegetables - a new report has revealed some surprising results. The study by the environmental nonprofit, Friends of the Earth (FOE), found that the district's Farm to School initiative not only provided its 48,000 or so students with access to healthier foods, but that between 2012 and 2015 its overall food costs declined and its carbon footprint shrank. The [Farm to School] program saves the district money because cooks prepare school meals from scratch. The lunch menu in OUSD schools transformed from a smorgasbord of processed foods to local, organic options. School cooks season and roast antibiotic-free chicken in-house, instead of heating up pre-cooked drumsticks. They also substitute frozen vegetables with fresh sides, like carrot salads made from scratch. In addition to a healthier menu, students get to go on field trips to local farms and take cooking classes through the program.
