Blenderized diets consist of a wide range of table foods such as fruits, vegetables, meat and legumes, pureed in a blender and administered via gastrostomy tube. In a recent study, the investigators reported that children receiving blenderized feeds via gastrostomy had fewer total admissions and respiratory admissions, total emergency room visits, and improved gastrointestinal symptom scores compared to those fed formula. The goal of this project is to understand how these diets affect gastroesophageal reflux burden.
