The case of the loathsome school lunches

"When Mina's school has a healthy eating assembly speaker, Mina and her classmates start thinking more about what they choose to eat. At lunch, she notices that many of the options being served to students are unhealthy. This gets her and her friends thinking: Why would the school promote healthy eating, but serve unhealthy foods? Something's not right, and Mina wants to get to the bottom of it"--Provided by publisher.
