Differences in gut bacteria may influence the effectiveness of dietary changes in individuals with multiple sclerosis (MS), according to a recent study published in Brain and Behavior. Researchers have indicated that specific gut microbiome compositions correlate with improvements in fatigue and quality of life for MS patients.

The study, which was limited to a small group, suggests a need for further research to confirm these findings and explore personalized dietary recommendations based on individual gut microbiomes. The researchers noted that future clinical practices may involve assessing a patient’s gut microbiome to tailor diet plans that optimize health benefits.
Currently, there is no universally recommended diet for MS patients, though guidelines typically emphasize a diet rich in fruits, vegetables, and lean proteins, while minimizing processed foods and sugars.
A separate clinical trial, WAVES (NCT02914964), conducted by researchers at the University of Iowa, tested two dietary interventions for MS patients: the modified Paleolithic elimination diet, or Wahls diet, and the low-saturated fat diet, or Swank diet. The WAVES study found that participants on either diet reported reduced fatigue and improved quality of life over several months.
In their analysis, researchers examining data from the WAVES study focused on dietary impacts on gut microbiome composition. They identified that diet significantly affects gut bacteria, which in turn can impact health and well-being. Using fecal samples from 23 participants, the study found that higher levels of certain bacteria before starting dietary interventions were associated with better outcomes in fatigue and quality of life measures.
Specifically, higher levels of bacteria such as Akkermansia and Bacteroides were linked to improved fatigue levels, while another group of bacteria was associated with less favorable quality of life results.
The researchers highlighted the potential for this type of analysis to guide more personalized dietary advice for MS patients. They also noted that gut microbiome compositions evolve over time, influenced by dietary changes.
Future studies are recommended with larger and more diverse cohorts to further investigate the relationships between gut microbiota, dietary changes, and MS symptoms. These studies could provide deeper insights into how diet-related microbial changes impact fatigue and immune function in MS patients.
