The normal diet, discussed in terms that patients can well understand, is described and illustrated by menus. Chapters are devoted to the bulk requirements of the body, the acid ash type of acidosis, the acetone type of acidosis, the caloric, the protein, the mineral, the vitamin and the water requirements of the body. The author believes that the acid ash foods bear a relation to high blood pressure. He states that in a series of fifty cases, there was a drop of from 40 to 50 points in 90 per cent, after the patients were put on the proper "basic" diet. Blood pressure usually has a considerable fluctuation, and it would be interesting to follow a similar number of cases over the same period of time in which treatment was not given.
