Objectives/Hypothesis To assess the impact of diet on the saliva pepsin concentration of patients with laryngopharyngeal reflux (LPR). Study Design Non‐controlled Prospective Study. Methods Patients with positive LPR regarding hypopharyngeal–esophageal impedance‐pH monitoring (HEMII‐pH) were enrolled from three European Hospitals. Patients collected three saliva samples, respectively, in the morning (fasting), and 1 to 2 hour after lunch and dinner. Patients carefully detailed foods and beverages consumed during meals and before the pepsin samples. The 3‐month treatment was based on the association of diet, proton pump inhibitors, alginate, or magaldrate regarding the HEMII‐pH characteristics. Reflux Symptom Score (RSS) and Reflux Sign Assessment (RSA) were used for assessing the pre‐ to posttreatment clinical evolution. The Refluxogenic Diet Score and the Refluxogenic Score of a Dish (RESDI) were used to assess the refluxogenic potential of foods and beverages. The relationship between saliva pepsin concentration, HEMII‐pH, RESDI, RSS, and RSA was investigated through multiple linear regression. Results Forty‐two patients were included. The saliva pepsin concentration of the 24‐hour period of testing was significantly associated with foods and beverages consumed during the testing period and the evening dinner ( r s = 0.973, P  < .001). RSS and RSA significantly improved throughout treatment. The level of saliva pepsin in the morning was a negative predictive factor of the therapeutic response regarding RSA and RSS ( P  < .036). Conclusions Foods and beverages may significantly impact the saliva pepsin concentration of patients with LPR. Patients with high‐level saliva pepsin in the morning had lower therapeutic response compared with those with low‐level saliva pepsin. Level of Evidence 4 Laryngoscope , 131:350–359, 2021
