The effects of dietary-induced acidosis on the growth and rates of complete regression of Sarcoma 180 in mice have been studied. The experiments here reported have demonstrated that mineral acidification of laboratory food produces a late decrease in tumor growth and significantly increases the rates of complete tumor regression. Blood acid-base studies also demonstrate the effects of these diets in altering the acid-base balance, and seemingly, this is independent of starvation and/or ketosis. The relationships of such in vivo acid-base metabolic changes to the control of tumor metabolism are briefly discussed. A therapeutic potential for this preliminary approach is considered.
