Practical Dietetics is a book by Alida Frances Pattee, first published in 1910. Designed as both a teaching text and a household guide, it brings together the principles of early nutrition science with clear, practical instruction. Pattee outlines the foundations of food values, digestion, balanced meals, and the role of diet in maintaining health, presenting the material in a way that is accessible to students, home cooks, and anyone interested in how dietetics was practiced in the early twentieth century. The book also serves as a detailed manual for therapeutic and convalescent diets. Pattee offers structured guidance on feeding the sick, preparing special diets for conditions such as diabetes or digestive disorders, and planning economical menus for families and institutions. Blending everyday cookery with emerging scientific approaches to nutrition, it stands as an important historical reference for the development of dietetics, hospital diet kitchens, and practical home care.
