Alkaline diet
The Alkaline diet (also known as the alkaline ash diet, alkaline acid diet and the acid alkaline diet) is a diet based on the theory that certain foods, when consumed, leave an alkaline residue, or ash. Minerals containing elements like calcium, iron, magnesium, zinc, copper, are said to be the principal components of the ash. A food is thus classified as alkaline, acid or neutral according to the pH of the solution created with its ash in water. One of the most famous proponents of the alkaline diet is Robert Young, who has come under scrutiny from the National Council Against Health Fraud.[1]
Foods
In general, the diet involves eating certain fresh citrus and other low-sugar fruits, vegetables, tubers, nuts, and legumes and avoiding grains, dairy, meat, sugar, alcohol, caffeine and fungi. Such a diet is alleged to help to maintain the balance of the slight alkalinity (7.35-7.45) of blood without stressing the body's regulators of acid-base homeostasis.[2]
Proponents and criticism
Proponents suggest adhering to the alkaline diet might prevent cancer, fatigue, obesity and allergies.[3] However, there is little to support these claims beyond some evidence suggesting that an alkaline diet might aid bone health,[4] [5][6] and some evidence that cancer cells grow more quickly in an acidic solution in a lab setting.[7] There is little scientific evidence to support the wide-ranging health claims of the alkaline diet proponents.
A similar theory, called the Hay diet, was developed by the American physician William Howard Hay in the 1920s. A later theory, called nutripathy, was developed by another American, Gary A. Martin, in the 1970s.[8] Others who have promulgated alkaline-acid diets include Edgar Cayce, D. C. Jarvis, Robert Young, Herman Aihara,[9] Fred Shadian, and Victor A. Marcial-Vega.[citation needed]
The theory behind the alkaline diet is not widely accepted by the medical community.[7]
