- Study Links Fish Consumption to Slower Disability Progression in Multiple Sclerosis
Published:
A groundbreaking study published in the Journal of Neurology, Neurosurgery and Psychiatry on February 25, 2025, suggests a promising link between fish consumption and the slowing of disability progression in individuals wiht Multiple Sclerosis (MS). the research indicates that a higher intake of both lean and oily fish is associated with a notable reduction in the advancement of MS-related disabilities. This finding offers a potential avenue for exploring dietary interventions to manage the debilitating effects of this neurological condition, providing new hope for those seeking ways to mitigate the impact of MS on their lives.
The study, which utilized data from a Swedish registry, suggests that incorporating fish into the diet may offer a protective effect against the worsening of MS-related disabilities. Experts emphasize the importance of a balanced diet for individuals with MS, and this new research provides further evidence supporting the inclusion of fish as a beneficial component. The findings underscore the potential of dietary modifications as a complementary approach to managing this complex condition.
Key Findings of the Study
The research,titled ‘Impact of fish consumption on disability progression in multiple sclerosis’ by Eva Johansson et al., delves into the correlation between dietary habits and the advancement of MS. The study highlights that consistent consumption of lean and oily fish is linked to lower disability progression. Even individuals who increased their fish intake after being diagnosed with MS experienced a reduced, though less pronounced, disability progression.
The study’s methodology involved analyzing data from a large cohort of MS patients in Sweden, tracking their dietary habits and disability progression over time. Researchers meticulously controlled for various confounding factors to isolate the specific impact of fish consumption. The results consistently showed a statistically significant association between higher fish intake and slower disease progression,reinforcing the potential benefits of this dietary intervention.
Dr. Shelly Coe, Senior Lecturer in Nutrition Science at Oxford Brookes University, commented on the study’s strengths, stating: It is great to see more research into MS and diet approaches for managing symptoms and disability progression, with the current research showing that higher lean and oily fish consumption is associated with a reduced risk of MS disability progression. Benefits of this study include the high sample size and that people with MS have a confirmed diagnosis and are recruited from clinics throughout Sweden.
Dr. Coe also noted a potential limitation, explaining: Fish consumption is assessed with a 4-point scale for oily or lean fish intake, and thus this could result in some limitations; though considering the study design this is overall a suitable method for assessing diet in this population.
Expert Perspectives on the Implications
Neurologists and nutrition experts have weighed in on the importance of these findings, offering valuable insights into the potential mechanisms and broader implications for MS management. Their perspectives highlight the importance of considering dietary interventions as part of a thorough approach to treating MS.
Dr. Aravinthan Varatharaj, Clinical Lecturer in Neurology at the University of Southampton, emphasized the robustness of the study, stating: This is a well-conducted study with robust findings. Sweden has an excellent registry where most people with multiple sclerosis include their data. Using this data, the researchers found that people eating more fish were relatively protected against worsening of their disability.
Dr. varatharaj further elaborated on the potential reasons behind the observed benefits: All fish contain important nutrients and amino acids which are beneficial for health. Oily fish contain essential omega-3 fatty acids which cannot be or else produced by the human body. UK guidelines recommend we eat at least two portions of fish per week, with at least one of oily fish. Though, most people in the UK eat less than this, and only a minority regularly eat oily fish.People with multiple sclerosis already know the importance of a healthy balanced diet, and this study is another bit of evidence to say that eating more fish is good for you.
He also highlighted the positive impact of dietary changes post-diagnosis: The study also showed that for people who didn’t each much fish and were diagnosed with multiple sclerosis, if they started eating more they still benefited.This goes to show that making a lifestyle change after diagnosis can have a positive impact.
However, Dr. Varatharaj cautioned against oversimplification, noting potential confounding factors: Dietary studies can be at risk of confounding by hidden factors. One thing this study didn’t look at is whether people who ate less fish were also less well-off. Fish can be expensive, so this could be a factor. We know that people with lower incomes have worse health outcomes (for multiple sclerosis and many other conditions).
Dr. Ruth Dobson, Clinical Senior Lecturer in Neurology (Multiple Sclerosis) at Queen Mary University of London (QMUL), acknowledged the long-standing hypothesis surrounding fish consumption and MS: The Swedish EIMS study has done a lot to enhance our understanding of MS epidemiology. The question about fish consumption playing a role in MS susceptibility and/or severity is one that has been hypothesised for some time from a biological basis. Diet is of significant interest to people living with MS, and high quality studies to investigate the effect of diet are hard to do; this study provides a realy useful avenue for examination.
Dr. Dobson also pointed out the consistent dose-response relationship observed in the study: Ther appears to be a consistent dose-response relationship between fish consumption and MS severity, the first time this has been reliably described. Notably, the same is true for physical activity and smoking behavior, which has been shown before.
while acknowledging the study’s strengths, Dr.Dobson also emphasized the need for further research to fully elucidate the underlying mechanisms: I don’t think this fully answers the question about whether it is indeed fish consumption directly that influences MS (even though this is wholly plausible), whether it is synergistic with other lifestyle traits (I think this is most likely), or whether it is purely acting as a surrogate for other lifestyle traits (less likely). They do adjust for some of these but residual confounding remains a concern in all studies like this. But the paper as presented is fair and does discuss this.
Implications for MS patients and future Research
The findings of this study offer a glimmer of hope for individuals with MS, suggesting that dietary modifications, specifically increased fish consumption, may play a role in slowing the progression of disability. While further research is needed to fully understand the underlying mechanisms and potential confounding factors, this study provides a strong foundation for exploring dietary interventions as a complementary approach to managing MS.
The study, published with DOI: 10.1136/jnnp-2024-335200, encourages further investigation into the synergistic effects of diet, lifestyle, and other factors in influencing the course of MS. As research continues, individuals with MS are advised to consult with their healthcare providers to discuss personalized strategies for managing their condition, including dietary considerations. The potential benefits of incorporating fish into a balanced diet warrant further exploration and personalized guidance from medical professionals.

This is not just a simple association; it suggests a causal link deserving of continued examination and further research into the underlying mechanisms.
Understanding the Mechanisms: Omega-3s, Inflammation, and More
Interviewer: The study highlights the potential role of omega-3 fatty acids. Can you elaborate on the possible mechanisms by which fish consumption might influence MS progression?
Dr. Sharma: The exact mechanisms remain an area of ongoing research, but several hypotheses are being explored. Omega-3 fatty acids, abundant in oily fish like salmon and mackerel, possess potent anti-inflammatory properties. MS is characterized by chronic neuroinflammation, so reducing inflammation through dietary means could significantly impact disease progression. Additionally, fish are rich in other nutrients, including vitamin D, vitamin B12, and various antioxidants, all of which play crucial roles in supporting neurological health. Further research is needed to determine the precise contribution of each nutrient and to fully understand the complex interplay between diet and MS pathophysiology.
Dietary Recommendations and Lifestyle changes
Interviewer: Based on this research, what dietary recommendations would you offer to individuals with MS, and how can these be integrated into a broader lifestyle approach?
Dr. Sharma: While this study provides compelling evidence, it’s crucial to emphasize that it’s just one piece of the puzzle. Individuals with MS should consult their healthcare providers before making significant dietary changes. That being said, this research suggests that increasing fish consumption – aiming for at least two servings per week, including oily fish – could be a beneficial addition to a balanced diet. This should be viewed within the context of a holistic approach to MS management:
balanced Diet: Prioritize a diet rich in fruits, vegetables, whole grains, and lean protein.
regular Exercise: Incorporate regular physical activity tailored to individual fitness levels.
Stress Management: Implement stress-reduction techniques like meditation or yoga.
Adequate Sleep: aim for 7-9 hours of quality sleep per night.
Integrating these lifestyle changes alongside dietary adjustments may offer a multi-faceted strategy to manage MS symptoms and potentially slow disease progression.
Future Research and Clinical Implications
Interviewer: What are the next steps in this research, and what are the broader implications for the clinical management of MS?
Dr. Sharma: Future studies should focus on larger, more diverse populations, investigating the precise mechanisms through which fish consumption influences MS progression. Exploring different types and amounts of fish to determine optimal intake levels is also crucial. Clinical trials are needed to assess the effectiveness of fish-enriched diets as a standalone therapy or in combination with existing MS treatments. The ultimate goal is to develop personalized dietary recommendations for individuals with MS,tailoring nutritional interventions to specific needs and genotypes. The potential for dietary modifications to positively affect both disease management and quality of life significantly warrants further research and clinical investigation
