 All faculty and delegates will be invited to participate in this observational, dietary study. The investigators expect to recruit all, or nearly all, of those attending. The fixed menu provided every night by the restaurant will be the same whether the attendee does or does not participate in the study unless specific dietary requirements are present. Involvement of almost all attendees will reduce selection bias; however, selection bias will remain because the group of clinical academics is not wholly representative of the general population. Note that the study population is predominantly male, with an older age and a larger waist circumference than the average in the community. These are all risk factors for reflux disease. This should increase study power to show treatment effect and the clinical relevance of findings.
