"Organic," "sustainable" and "food miles" all appear in the comprehensive glossary of this book, whose simple title and cover photograph imply a basic approach to the international topic of food. This very political book, biased toward food equity, explains why certain foods are eaten in certain countries and why school lunches are important. They fill various needs, from the teaching of courtesy and table manners in France and Japan to the supply of basic nutrients for Somali children in refugee-camp schools. Efforts to improve children's eating habits, curb obesity, encourage use of local crops and provide food to students with limited economic resources are discussed. As the book is from Canada, naturally there are some references to that country in many of the comparisons. Though published in a seemingly picture-book format, the text is complex. Most two-page spreads describe school lunchtime in an individual country, with a cartoonish illustration on the left and a large photograph of a typical meal on the right with numbered arrows pointing to particular elements. Lengthy captions are keyed to each number. Small globe images in each spread point out countries, but larger maps and a bibliography would be useful. "The Message to Parents, Teachers and Students" provides project ideas. Adults may have to force-feed this purposive book to those not yet committed to the important causes outlined here.
