Dr. Otto Wolff, known to English-language readers through his home remedies, offers a clear description of the foods we eat and what we should really look for in them. Topics include raw food diet, milk products, fats, sugar and meat. Whichever it may be, we know more about the value of a food once we have read the chapter, and are able to form an opinion on what is becoming more and more of a burning question -- the quality of the food we eat.
