The principle of the pH diet is that the most important aspect of a balanced, healthy body is our pH, or acid/alkaline balance.

pH is an abbreviation for ‘potential of hydrogen’. It indicates the acidity or alkalinity of a solution, measured on a scale of 0–14. The lower the pH, the more acidic the solution; the higher the pH, the more alkaline the solution. When a solution is neither acid nor alkaline, it has a pH of 7, which is neutral.

You may have a vague idea about pH from school chemistry lessons, but pH is also used to market cosmetics and hair care products. ‘pH-balanced’ products are formulated to complement the pH of skin and hair. If you use products that are too acidic or too alkaline in nature, they may be damaging. If you wash your hair with detergent, for example, you wouldn’t expect your locks to shine. Your hair would be clean but dry, dull and totally unmanageable. So choosing foods that are the wrong pH could leave you with the equivalent of a dry, dull and lifeless body. Visible signs will appear on the outside, reflected in poor-condition hair, nails and skin. On the inside, this imbalance shows up as symptoms that reflect the poor functioning of our internal organs (see the box on page xii to check any symptoms you may have).
