With great interest I read the report by Whitington and Gibson on soy protein intolerance (Pediatrics 59:730, May 1977). In the Archives of Diseases in Childhood of May 1975, the study group for gastrointestinal disorders at the Children's Hospital, University of Helsinki, Finland, presented 54 infants with the malabsorption syndrome with cow's milk intolerance.1 Thirty-five of these 54 infants received soy protein as a substitute for cow's milk. Four of these 35 infants had concomitant soy protein intolerance.
