In 1924, Haas achieved notice when he published a medical paper detailing his use of a banana diet for the treatment of the eight children diagnosed with celiac disease. Haas incorrectly concluded that bananas enabled the breaking up of starches and the conversion of cane sugar into fruit sugar, which prevented the debilitating diarrhea of celiac disease.[2][3] Haas’ research led to the development of the Specific Carbohydrate Diet, a nutritional regimen that restricted the use of complex carbohydrates (disaccharides and polysaccharides) and eliminated refined sugar, gluten and starch from the diet.[4] Haas never accepted the finding that gluten was the damaging part of wheat; he insisted it was starch and called the discovery about a gluten a "disservice".[5]
During his career, Haas treated over 600 cases of celiac disease. In 1951, he joined his son, Dr. Merrill P. Haas, in publishing the medical textbook The Management of Celiac Disease.[1][6]
