Much of the recent voluminous literature on nutrition has been revised and significant additions have been incorporated in the fifth edition. Tables summarizing the effects of vitamins on the body, sources of supply and recommended daily allowances give much information in a concise form. Other tables give analysis of foods that serve to meet basic requirements, symptoms of deficiency states, conditions that influence vitamin requirements and utilization and other significant data. In general, tables are well constructed, clear and contain sound current information. A number of excellent colored photographs add considerably to the value of the book. Seven photographs show comparative servings of foods in such a clear manner that they should be helpful to the physician in diet prescription. Effects of deficiency diseases are shown in three colored photographs and experimental studies in humans on a deficient vitamin C diet clearly show alterations in the healing pattern of wounds.
