Food is talked about endlessly in the media, at local, regional, national and indeed global levels. People are always wondering, therefore, about what is "good" or "right" to eat. To look for answers without giving enough consideration to trends and fashions, without thinking of the bigger picture, the implications of what people eat and how they shop, would only mislead them. Teaching about a single food issue such as genetic manipulation, local food procurement or food poisoning in isolation is impossible. The politics of food policy is also uncertain: do governments rely on scientific research, or do they listen mainly to the big producers and retailers? This article presents the author's points of view and questions that can help teachers and children think about the food they eat, both in school and at home. The author discusses how teachers can improve the way they teach about healthy eating in school. (Lists 3 online resources.)
