Abstract
BACKGROUND: Plant-based formulas have become increasingly popular due to their health benefits, environmental concerns, cultural beliefs, improved palatability, and decreased cost. A retrospective chart review of medically stable children transitioning from a hypoallergenic formula to a yellow pea protein plant-based formula (PPPBF) was included. This study aimed to assess gastrointestinal tolerance, weight changes, and adherence to receiving a unique PPPBF. METHODS: Healthcare providers (HCPs) from pediatric clinics across the United States who requested increased PPPBF samples between the dates of 1 November 2021and 31 January 2022 and again from 1 February 2022 to 15 April 2022 inputted survey data. The HCPs selected participants based on the inclusion criteria. RESULTS: Seventy-three completed patient surveys were included of children (ages 1-18 years old, 41% females, 59% males). After the transition to PPPBF, 38.4% experienced improvement in GI tolerance, 56.2% experienced no change, and 5.5% reported worsening GI tolerance. There was a 95% adherence rate, and 98.9% reported no adverse reactions or allergic manifestations after formula transition. CONCLUSIONS: Transitioning from a hypoallergenic formula to a PPPBF showed a trend toward stable GI tolerance, weight gain or stability, and adherence. A PPPBF offers a first-choice option for children who are on hypoallergenic formulas due to intolerance.
