A new study from Sweden suggests that eating fish regularly may help slow disability progression in people with multiple sclerosis (MS). The research found that people with MS who consumed more fish had a 34 percent lower risk of worsening disability over time.

Researchers analyzed data from more than 2,700 people with MS, tracking their consumption of lean and oily fish and their disability progression for up to 15 years. Lean fish included cod, pollock, and haddock, while oily fish included tuna, salmon, and trout. They found that higher total consumption of both lean and oily fish at the time of diagnosis was linked to a reduced risk of disability worsening, as measured by the Expanded Disability Status Scale (EDSS).

The slowing of disability accumulation was even more pronounced for people who maintained consistent fish consumption over time. Those who increased their fish intake after diagnosis also saw a reduced risk of disability progression.

Why Might Fish Help Slow MS Progression?

Fish is rich in omega-3 fatty acids, which have anti-inflammatory properties and may help protect nerve cells. The study also highlights taurine, an amino acid found in fish, as a potential contributor to its benefits. Taurine has antioxidant and anti-inflammatory effects that could play a role in slowing MS progression.

Additionally, diet can influence gut bacteria, which may impact the immune system and inflammation levels — both of which are important for people with MS.

The Connection Between MS and Diet

MS treatments have improved in recent years, but disability progression remains a challenge. This study supports the idea that lifestyle factors, including diet, can complement medical treatments. Along with disease-modifying therapies, making informed dietary choices may help people with MS manage their symptoms and maintain their quality of life.

Before making any major dietary changes, it’s best to consult with a doctor or dietitian to ensure the diet is balanced and supports overall health.
