Eating lots of fresh fruit and vegetables and other whole foods is a staple of the alkaline diet. Too much acidic food can create inflammation and illness, so that's another thing to keep in mind. For optimal health, the human body requires a precise equilibrium between acid and alkaline environments. A value of 7.4 seems about right for this (on a scale of 0-14). Alkaline diet proponents argue that the acidity of modern Western diets contributes to illness and obesity. A new window will open with naturopath Louise Westra's full explanation of the pH scale: "The pH scale quantifies how acidic or basic something is, on a range of 0 to 14. An alkaline substance has a pH higher than 7. The proponents of this theory think that better health and illness prevention may be achieved by making the body's pH more alkaline and less acidic.
