The observance of rules of food combining is neither faddish nor eccentric. It is a simple, scientifically -based system of selecting foods, from among different types, which are compatible. This facilitates easy and efficient digestion and ensures after-meal comfort.
Digestion is not merely chemical or physical process, but also a physiological one. When food enters the body, it undergoes several changes before it is broken down into its constituent parts and assimilated. But no food can be assimilated by the system and used by various organs unless it has first been digested and then absorbed in the digestive system known as alimentary canal, while the residue, unfit for absorption is eliminated from the system.
The chemical part of digestion is accomplished by a series of juices and their enzymes. The juices alternate between alkalies and acids, and their character is determined by the requirement of the enzymes they contain. These enzymes remain active in suitable media of well defined acid-alkaline ranges and are destroyed in unsuitable media.
