What Have You Been Eating? is an inappropriately specific title for such a general book. In fact, in addition to covering food composition and food additives, [Margaret O. Hyde and Elizabeth Held Forsyth] discuss the digestive system, food history, food customs, world food supply, and various plans for combatting starvation now and in the future. The breadth of the subject and the brevity of the book impose a cursory and superficial coverage of each topic. A lack of structure makes it difficult to locate information without reading the entire book. The style is awkward and condescending. Students will already have covered much of the information in basic science and geography courses. Not recommended.
