Dr Hay Diet Meals

The Hay Diet is a nutrition method developed by the New York physician William Howard Hay in 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 protein rich, meat, fish, dairy, etc., and "alkaline" the carbohydrate-rich starch foods like rice, grains and potatoes.

It is also known as the food combining diet, and many authors have written books expressing its merits and selling recipes.
