Comparison of dietary acid load score between celiac patients and healthy population

BACKGROUND AND AIMS: In the present study, we assessed the dietary acid load in adult celiac patients and compared it with that of the healthy population to provide more specific dietary recommendations for celiac patients. METHODS: This study was a cross-sectional study that included 130 celiac patients and 462 Non-celiac participants. The 80-item semi-quantitative food frequency questionnaire was used to obtain dietary data. Based on the dietary data, the dietary acid load (DAL), Potential renal net acid load (PRAL), and net endogenous acid production (NEAP) were calculated. RESULTS: The mean PRAL value is negative in the celiac group but positive in the general population. There was a significant difference in the PRAL score between celiac patients and the general population (p < 0.001). The mean NEAP and DAL score were significantly lower in the celiac group compared with the healthy population (P < 0.001). There were no significant differences between gluten-free diet adherents and non-adherents regarding the PRAL, NEAP, and DAL values (P > 0.05). CONCLUSION: We showed that the patients with celiac disease had a significantly less acidogenic diet compared with that of the general population. So, following dies low in gluten may be associated with less acid production spacially in populations at risk of acid/base imbalance.
