Dietary modification for laryngopharyngeal reflux: systematic review

  • C Min (a1) (a2) (a3), B Park (a2), S Sim (a4) and H G Choi (a1) (a2)



This study aimed to determine the relationship between laryngopharyngeal reflux and dietary modification.


A systematic review was conducted. The data sources for the study were PubMed, Embase, Cochrane Library and Web of Science. Articles were independently extracted by two authors according to inclusion and exclusion criteria. The outcome focus was laryngopharyngeal reflux improvement through diet or dietary behaviour.


Of the 372 studies identified, 7 met our inclusion criteria. In these seven studies, laryngopharyngeal reflux symptoms improved following dietary modifications. However, the studies did not present the independent effect of each dietary factor on laryngopharyngeal reflux. Moreover, only one of the seven studies had a randomised controlled study design.


The reference studies of dietary modification for laryngopharyngeal reflux patients are not sufficient to provide recommendations.
