Food combining

Food combining (also known as trophology) is a term for a nutritional approach that advocates specific combinations of foods as central to good health and weight loss (such as not mixing carbohydrate-rich foods and protein-rich foods in the same meal). It has been described by medical health experts as a "pseudo-scientific system" and quackery.[1]

This is a diet for digestive comfort rather than exclusively for weight loss. For example, carbohydrates cause fermentation depending on the sequence of foods in digestion.

It was originally promoted by Herbert M. Shelton in his book Food Combining Made Easy (1951).[1]

The best-known food-combining diet is the Hay Diet; Hay lost 30 pounds in 3 months when he implemented his research. One randomized controlled trial of food combining has been performed, and found no evidence that food combining was any more effective than a "balanced" diet in promoting weight loss.[2]

Food combining adherents believe that watermelon and other melons should be consumed separately from other foods.[3][4]
