Abstract

Background: Current evidence suggests that adherence to the Mediterranean diet (MeD) can reduce inflammation in chronic diseases; however, studies pertaining to relapsing-remitting multiple sclerosis (RRMS) are limited. Therefore, the aim of this study was to investigate the potential of the modi ed MeD (mMeD) in improving Dietary Inflammatory Index (DII) scores, disability and fatigue severity, compared with traditional Iranian diet (TID), in RRMS patients. Results: Of the 180 patients enrolled, 147 participants were included in the i nal analysis (n of mMeD = 68; n of TID = 79). Self-reported adherence was good (81 %). Dietary intakes of forty-five food parameters were assessed through the FFQ. The mMeD significantly reduced DII scores after 6 months (238 ± 021 to -187 ± 086, P < 0001), but TID did not elicit any changes (221 ± 044 to 214 ± 101, P = 0771). Additionally, Modified Fatigue Impact Scale (MFIS) total score decreased significantly (724 ± 172 to 639 ± 142, P < 0001), whereas there was no considerable improvement for Expanded Disability Status Scale (EDSS) in the mMeD group. Methods: After initial screening (n 261), 180 RRMS patients were randomised to receive mMeD or TID (as control) for 6 months. DII score, EDSS and twenty-one-item MFIS were evaluated at baseline and trial cessation. Multivariate ANCOVA was conducted and adjusted for age, gender, body weight, BMI, education level, supplement use, family history and duration of MS. Conclusion: Adherence to mMeD, for 6 months, improved dietary inflammatory status and fatigue severity in RRMS patients; however, the TID did not positively impact dietary inflammation and MFIS score. ©
