Nutripathy is a form of alternative medicine that is concerned with the pH of the body and its fluids. In general, pH is considered important by conventional medicine as well, but Nutripathy considers it critical. Typically the pH of blood or urine is frequently measured, and foods are ingested that supposedly help control the pH.

Foods are usually classified to be either acid-forming or alkaline forming by measuring the acidity of the oxidized remains of the food.
