Objectives/Hypothesis: To investigate the efficacy of low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet as single treatment for patients with laryngopharyngeal reflux (LPR). Study Design: Cross-over observational study. Methods: Patients with LPR diagnosis at the hypopharyngeal-esophageal multichannel intraluminal impedance-pH-monitoring were prospectively recruited from the reflux clinic of three University Hospitals. Patients were instructed to follow low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet for 6 to 12 weeks. Pre- to post-treatment symptom and finding changes were evaluated with reflux symptom score (RSS) and reflux sign assessment. Findings were compared to those of a control period where patients did not receive any treatment or diet. Diet was evaluated with refluxogenic diet score (REDS). Results: Fifty patients completed the study (19 males). Otolaryngological, digestive, and total RSS scores significantly improved from baseline to 6-week post-diet, while there were no significant changes during the control period. At 6-week post-diet, 37 (74%) patients reported significant symptom improvement or relief. Among them, symptoms continued to improve from 6 to 12 weeks in 27 cases, corresponding to a diet success rate of 54%. The REDS was predictive of the baseline RSS (P =.031). Conclusion: Low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet is an alternative cost-effective therapeutic approach for patients with LPR. Patients with higher REDS reported higher baseline symptom score. Level of Evidence: 3 Laryngoscope, 132:1916–1923, 2022.

Abstract

Objectives/Hypothesis: To investigate the efficacy of low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet as single treatment for patients with laryngopharyngeal reflux (LPR). Study Design: Cross-over observational study. Methods: Patients with LPR diagnosis at the hypopharyngeal-esophageal multichannel intraluminal impedance-pH-monitoring were prospectively recruited from the reflux clinic of three University Hospitals. Patients were instructed to follow low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet for 6 to 12 weeks. Pre- to post-treatment symptom and finding changes were evaluated with reflux symptom score (RSS) and reflux sign assessment. Findings were compared to those of a control period where patients did not receive any treatment or diet. Diet was evaluated with refluxogenic diet score (REDS). Results: Fifty patients completed the study (19 males). Otolaryngological, digestive, and total RSS scores significantly improved from baseline to 6-week post-diet, while there were no significant changes during the control period. At 6-week post-diet, 37 (74%) patients reported significant symptom improvement or relief. Among them, symptoms continued to improve from 6 to 12 weeks in 27 cases, corresponding to a diet success rate of 54%. The REDS was predictive of the baseline RSS (P =.031). Conclusion: Low-fat, low-quick-release sugar, high-protein, alkaline, and plant-based diet is an alternative cost-effective therapeutic approach for patients with LPR. Patients with higher REDS reported higher baseline symptom score. Level of Evidence: 3 Laryngoscope, 132:1916–1923, 2022.
