Abstract
PURPOSE People with multiple sclerosis (pwMS) want disease-specific dietary advice to reduce the confusion around diet. This study used co-design principles to develop an online nutrition education program for pwMS. METHODS Mixed-methods (multiphase sequential design). Phase 1: online survey (n = 114 pwMS) to explore preferred content and characteristics of a nutrition program and develop a draft program. Phase 2: feedback on the draft program from stakeholders (two meetings; n = 10 pwMS and multiple sclerosis (MS) health professionals) and pwMS (two workshops; n = 6) to produce a full program prototype. Phase 3: cognitive interviews (n = 8 pwMS plus 1 spouse) to explore acceptability and ease of comprehension of one module of the program, analysed using deductive content analysis. RESULTS Preferred topics were included in the program, which were further developed with consumer feedback. Cognitive interviews produced four themes: (1) positive and targeted messaging to motivate behaviour change; (2) "not enough evidence" is not good enough; (3) expert advice builds in credibility; and (4) engaging and appropriate online design elements are crucial. CONCLUSIONS Positive language appears to improve motivation to make healthy dietary changes and engagement with evidence-based nutrition resources. To ensure acceptability, health professionals can use co-design to engage consumers when developing resources for pwMS.IMPLICATIONS FOR REHABILITATIONCo-designed nutrition education programs can help people achieve high-quality diets in line with recommendations, but very few programs exist for people with multiple sclerosis (MS), and none were co-designedThe participatory research in this study was instrumental in ensuring that important information regarding program acceptability was identifiedCo-design can ensure that the language is appropriate for the target audience, and positive language appeared to improve motivation in people with MS to engage with the online nutrition education programWhere practical and feasible, health professionals should collaborate with MS consumers when developing resources, and use positive, empowering language.

Abstract
Background People with multiple sclerosis (MS) often report dietary modifications; however, evidence on functional outcomes remains sparse. Objective Evaluate the impact of the low-saturated fat (Swank) and modified Paleolithic elimination (Wahls) diets on functional disability among people with relapsing-remitting MS. Methods Baseline-referenced MS functional composite (MSFC) scores were calculated from nine-hole peg-test (NHPT), timed 25-foot walk, and oral symbol digit modalities test (SDMT-O) collected at four study visits: (a) run-in, (b) baseline, (c) 12 weeks, and (d) 24 weeks. Participants were observed at run-in and then randomized at baseline to either the Swank (n = 44) or Wahls (n = 43) diets. Results Among the Swank group, MSFC scores significantly increased from -0.13 ± 0.14 at baseline to 0.10 ± 0.11 at 12 weeks (p = 0.04) and 0.14 ± 0.11 at 24 weeks (p = 0.02). Among the Wahls group, no change in MSFC scores was observed at 12 weeks from 0.10 ± 0.11 at baseline but increased to 0.28 ± 0.13 at 24 weeks (p = 0.002). In both groups, NHPT and SDMT-O z-scores increased at 24 weeks. Changes in MSFC and NHPT were mediated by fatigue. Discussion Both diets reduced functional disability as mediated by fatigue. Trial Registration Clinicaltrials.gov Identifier: NCT02914964.

Efficacy of Diet on Fatigue and Quality of Life in Multiple Sclerosis: A Systematic Review and Network Meta-analysis of Randomized Trials. Neurology 2023; 100:e357-e366. [PMID: 36257717 DOI: 10.1212/wnl.0000000000201371] [Citation(s) in RCA: 20] [Impact Index Per Article: 20.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2022] [Accepted: 08/23/2022] [Indexed: 01/25/2023] Open
Abstract
BACKGROUND AND OBJECTIVE Emerging evidence suggests a role for diet in multiple sclerosis (MS) care; however, owing to methodological issues and heterogeneity of dietary interventions in preliminary trials, the current state of evidence does not support dietary recommendations for MS. The objective of this study was to assess the efficacy of different dietary approaches on MS-related fatigue and quality of life (QoL) through a systematic review of the literature and network meta-analysis (NMA). METHODS Electronic database searches were performed in May 2021. Inclusion criteria were (1) randomized trial with a dietary intervention, (2) adults with definitive MS based on McDonald criteria, (3) patient-reported outcomes for fatigue and/or QoL, and (4) minimum intervention period of 4 weeks. For each outcome, standardized mean differences (SMDs) were calculated and included in random effects NMA to determine the pooled effect of each dietary intervention relative to each of the other dietary interventions. The protocol was registered at PROSPERO (CRD42021262648). RESULTS Twelve trials comparing 8 dietary interventions (low-fat, Mediterranean, ketogenic, anti-inflammatory, Paleolithic, fasting, calorie restriction, and control [usual diet]), enrolling 608 participants, were included in the primary analysis. The Paleolithic (SMD -1.27; 95% CI -1.81 to -0.74), low-fat (SMD -0.90; 95% CI -1.39 to -0.42), and Mediterranean (SMD -0.89; 95% CI -1.15 to -0.64) diets showed greater reductions in fatigue compared with control. The Paleolithic (SMD 1.01; 95% CI 0.40-1.63) and Mediterranean (SMD 0.47; 95% CI 0.08-0.86) diets showed greater improvements in physical QoL compared with control. For improving mental QoL, the Paleolithic (SMD 0.81; 95% CI 0.26-1.37) and Mediterranean (SMD 0.36; 95% CI 0.06-0.65) diets were more effective compared with control. However, the NutriGRADE credibility of evidence for all direct comparisons is very low because of most of the included trials having high or moderate risk of bias, small sample sizes, and the limited number of studies included in this NMA. DISCUSSION Several dietary interventions may reduce MS-related fatigue and improve physical and mental QoL; however, because of the limitations of this NMA, which are driven by the low quality of the included trials, these findings must be confirmed in high-quality, randomized, controlled trials.

Abstract
BACKGROUND There are approximately 1 million adults in the United States with multiple sclerosis (MS). Persons with MS are interested in diet as a second-line therapy for improving MS symptoms and disease progression. Examination of desired resources regarding diet among persons with MS is necessary for supporting behavior change. METHODS Twenty-five adults with MS completed 1-on-1, online semistructured interviews. An inductive, 6-phase, semantic thematic analysis was applied to identify themes associated with participant preferences for dietary behavior change. RESULTS The research team crafted 4 key themes from the data that encompassed participants' desired resources for dietary behavior change. Theme 1, MS-specific evidence, involved the need for clear information about the impact of diet regimens or specific foods on MS. Theme 2, dietary guidelines, was related to guidelines provided by a reliable source such as a registered dietitian. Theme 3, behavioral supports, underscored the need for support for behavior change, including accountability, self-monitoring, motivation, habituation, and incremental changes. Theme 4, diet resources, highlighted tangible resources for supporting dietary change, including recipes, food lists, meal services, or games. CONCLUSIONS This study provides a foundation for guiding dietary interventions for persons with MS that incorporates their needs and preferences and could improve their overall health. Such dietary change can be facilitated by theory-based behavioral interventions that incorporate behavior change techniques such as self-monitoring and goal setting for supporting behavior change.

Abstract
INTRODUCTION It remains a matter of debate whether traditional concepts regarding the nature of food affect the development and progression of multiple sclerosis (MS).To date, there are limited studies that have investigated the association between MS and dietary patterns based on the categories of food nature (hot, cold, or balanced) defined in traditional medicine. METHOD This case-control study was conducted from October 2019 to February 2020. In total, 60 patients diagnosed with MS within the preceding 6 months and referred to our neurology outpatient clinic were included in our case group. The control group included 180 patients who were referred to the same center for general or orthopedic surgery. Dietary intake was assessed in both groups through a reliable and valid semi-quantitative food frequency questionnaire. Data were assessed using principal component analysis. RESULTS The mean age of the participants was 44.9 ± 17.33 years. The analysis showed that four food patterns were distinguished (eigenvalue > 1), namely "additives and cold-natured foods", "hot and balanced foods and nuts", "dairy and legumes", and "hot and balanced starches". These food patterns explained 57.8% of the total variance. After adjusting all confounding factors, individuals in the highest quartile and medium quartile of "additives and cold-natured foods" had an elevated MS risk compared with the lowest quartile (OR = 7.21, 95%CI = 2.01-12.38 and OR = 3.37, 95%CI = 1.02-11.35, respectively). Furthermore, individuals in the highest quartile of the "hot and balanced foods and nuts" group were protected against MS compared with its lowest quartile (OR = 0.28, 95%CI = 0.08-0.90). Moreover, a protective effect against MS was seen in the highest quartile of the "hot and balanced starches" group relative to its lowest quartile (OR = 0.34, 95%CI = 0.12-0.98). No significant association was found between "dairy and legumes" and the risk of MS. CONCLUSION This study revealed that dietary patterns based on the traditional concept of food nature might be associated with the risk of developing MS. This represents the first work in this area, so further research is recommended.

Abstract
BACKGROUND Diet has been associated with the onset and progression of multiple sclerosis (MS). Multiple diets, varying in recommendations, have been proposed as beneficial to people with MS. The characteristics of those who follow specific diet-programs and the relationships of these diet-programs with diet quality is under-explored. METHODS Data from the HOLISM study were analysed. Adherence to selected MS-specific diets (Ashton Embry Best Bet, McDougall, Overcoming MS (OMS), Palaeolithic, Swank, and Wahls Elimination) were each queried on 5-point Likert scales, and moderate (≥3/5) and rigorous (≥4/5) adherence defined. Sociodemographic and clinical characteristics of adherence were evaluated by log-binomial regression. Relationships of diet-program adherence with diet quality as measured by Diet Habits Questionnaire were assessed by linear and log-binomial regression, as appropriate, adjusted for age, sex, socioeconomic status (SES), education, and clinically significant fatigue. RESULTS Forty-nine percent of participants reported at least 12-month adherence to a diet-program for their MS. Of these, 31.3% rigorously adhered to OMS, 4.9% to Swank, 1.7% to Wahls, and <1.5% to other diet-programs. Only adherence to any diet-program, OMS, Wahls, and Swank, were quantitatively assessed. Females, and participants of lower-than-average SES and longer disease duration were less adherent to any diet-program for MS, as well as those with higher disability, more clinically significant fatigue, greater depression risk, and more comorbidities. Those with higher-than-average SES were more adherent, as were those with higher physical and mental quality of life. Similar relationships were seen for OMS diet-program adherence. Adherence to Wahls diet-program was higher among those with progressive MS types and longer disease duration. No associations were found for adherence to Swank diet-program. Overall diet quality was higher among participants following any diet-program, particularly OMS and Swank, but not Wahls. CONCLUSION Greater adherence to MS specific diets was associated with higher SES, and higher quality of life. Following any diet program was associated with higher overall diet quality, with those adhering to the OMS diet having the highest diet quality. These results may inform health professionals in providing guidance to patients regarding diet in MS.

Abstract
Objective To compare the effect of the modified Paleolithic elimination (Wahls) and low-saturated fat (Swank) diets in relapsing-remitting MS (RRMS). Methods Individuals (n = 87) with RRMS were randomized to the Swank or Wahls diets in a parallel group clinical trial consisting of four timepoints: 1) run-in, 2) baseline, 3) 12-weeks, and 4) 24-weeks. Results 77 participants completed 12 weeks and 72 completed 24 weeks. The 12-week change from baseline in fatigue was -0.94 ± 0.18 (FSS) and -9.87 ± 1.93 (MFIS; both p < 0.0001) for Swank, and -0.71 ± 0.24 (FSS; p = 0.004) and -14.41 ± 2.22 (MFIS; p ≤ 0.0001) for Wahls. Physical MSQoL scores improved by 6.04 ± 2.18 (p = 0.006) for Swank and by 14.5 ± 2.63 (p < 0.0001) for Wahls. Mental MSQoL scores improved by 11.3 ± at 2.79 (p < 0.0001) for Wahls while the Swank did not change (3.85 ± 2.63; p = 0.14). Neither group showed significant changes in 6-minute walking distance at 12 weeks. All outcomes were maintained or further improved at 24 weeks. Conclusions Both diets were associated with clinically meaningful within-group reductions in fatigue and improvements in QoL.Trial Registration: Clinicaltrials.gov Identifier: NCT02914964.
