We aimed to assess the relationship between fruit and vegetable consumption and GERD among a large group of  Iranian adults. </span><span class="fontstyle0">Materials and Methods: </span><span class="fontstyle2">In this cross?sectional study on  3979 adults, a validated food frequency questionnaire was used to assess usual dietary intakes including fruits and vegetables. Te presence of heartburn sometimes or more during the past 3 months were considered as having GERD. </span><span class="fontstyle0">Results: </span><span class="fontstyle2">Te prevalence of GERD among study population was 23.9%. After adjustment for potential confounding factors, those with the highest consumption of fruits had 25% lower risk for GERD, in comparison to those with the lowest intake (odds ratio [OR] = 0.75, 95% confdence interval [CI]: 0.59–0.97). Vegetable intake was not signifcantly related to the risk of GERD in crude or multivariable?adjusted models. However, participants with the highest intake of fruits and vegetables had 33% lower risk of GERD (OR = 0.67, 95% CI: 0.51–0.88), after  adjustment for confounders. Women with the highest fruit and vegetable intake had 36% lower risk for GERD (OR = 0.64, 95% CI: 0.45–0.91). Overweight/obese participants in the last tertile of fruit consumption had 42% lower risk for GERD, in comparison to the frst category (OR = 0.58, 95% CI: 0.42–0.83).
