Originally published in 1940, this concise book was based upon a series of articles that were written during 1938 and 1939. The text is organised around the principle of helping ordinary people to understand food nutrition during the scarcity of war, enabling them to choose alternatives when certain items become unavailable. It is divided into two sections: the first summarises the nutritional knowledge of the time and the ways in which consumption can be affected by war; the second contains food tables detailing the nutritional value of various food groups. This is an illuminating resource that will be of value to anyone with an interest in British history, the Second World War, public health, and nutrition.
