- Dr. Hay diet
The Dr. Hay diet (also called the Hay Diet) is a nutrition method developed by the New York physician
William Howard Hayin the 1920s. It claims to work by separating out food groups into those which are "alkaline, acidic and neutral". Acid foods are not combined with the alkaline ones. "Acid" foods are proteinrich, meat, fish, dairy, etc., and "alkaline" the carbohydrate-rich starch foods like rice, grains and potatoes.
It is also known as the
food combiningdiet, and many authors have written books expressing its merits and selling recipes.
A similar theory, called nutripathy, was developed by Gary A. Martin in the 1970s.

[http://www.csicop.org/si/9509/alternativism.html available online] ] Others who have promulgated alkaline-acid diets include

The food-combining diet has been the subject of one peer-reviewed
randomized clinical trial, which found no benefit from the diet in terms of weight loss.

Bright's disease(or what modern medicine refers to as Nephritis). Heart-dilated and near death, Dr. Hay began eating only natural foods; his calories intake dropped and his health improved. Dr. Hay spent the following decade studying naturopathyand food combining to reduce the acid end-product of digestion. He found that fruits and vegetables produce an alkaline end-product when they are fully metabolized, while processed and refined foods left a high acidic environment after digestion. His theories went on to encompass food-combining; whereas incorrect combination would cause even alkaline foods to leave a less desirable acidic digestion end-product. [Needes, Robin, "Naturopathy for Self-healing: Nutrition, Life-style, Herbs, Homoeopathy", "Acid Alkaline Balance". [http://books.google.com/books?hl=en&lr=&id=tyQXPxffMWIC&oi=fnd&pg=PA1&dq=%22Dr.+Hay+diet%22&ots=BMNXY2OiCz&sig=O0qL2mH7NR2q80NuKLSwCZ7pG-c#PPA29,M1 available online] ]
The Hay System promoted the practice of eating three meals per day with meal one being alkaline foods only, meal two protein foods with salads, vegetables and fruit, and meal three comprising starchy foods with salads, vegetables and sweet fruit. There should be an interval of 4.0 to 4.5 hours between each meal. However, in 1935, Dr. Stewart Baxter showed that the
pancreassecretes digestion enzymes simultaneously regardless of whether the food eaten is carbohydrates or protein. [Cardwell, Glenn, "The Skeptic", Nutrition: Food Combining, Vol 16, No 2. [http://www.skeptics.com.au/journal/1996/2_combining.pdf available online] ]
