The role of **anti-inflammatory diets in multiple sclerosis (MS)** centers on their potential to reduce inflammation, support immune system balance, and possibly slow disease progression or alleviate symptoms. MS is an autoimmune condition where the immune system mistakenly attacks the protective myelin sheath around nerve fibers in the central nervous system, leading to inflammation, nerve damage, and neurological symptoms. Since inflammation is a key driver of MS pathology, diets that help modulate or reduce inflammation are of great interest.
An **anti-inflammatory diet** typically emphasizes whole, nutrient-dense foods that are rich in antioxidants, healthy fats, vitamins, and minerals. These include leafy green vegetables, cruciferous vegetables (like broccoli and cauliflower), wild-caught fatty fish (rich in omega-3 fatty acids), extra virgin olive oil, and antioxidant-rich fruits such as berries. Herbs and spices like turmeric and ginger are also valued for their natural inflammation-modulating properties. This diet supports the immune system without overstimulating it, which is crucial in autoimmune diseases like MS.
Unlike more restrictive autoimmune diets, the anti-inflammatory diet is flexible and accessible, making it easier for many people to adopt as a long-term lifestyle change. However, it may still include some foods that could trigger symptoms in sensitive individuals, such as eggs, nightshades (tomatoes, potatoes, peppers, eggplant), nuts, seeds, gluten-free grains, and legumes, so personal adjustments may be necessary.
Research into specific dietary patterns for MS, such as the Mediterranean diet or modified versions like the MIND diet, shows promise. These diets combine anti-inflammatory foods and have been linked to reductions in blood markers associated with inflammation and neurodegeneration. Preliminary studies suggest that such diets may help slow disease progression and improve quality of life by limiting neuroinflammation and promoting neuroprotection.
Other dietary approaches studied in MS include ketogenic diets and fasting-mimicking diets. The ketogenic diet, which is high in fats and low in carbohydrates, may reduce systemic inflammation by altering the gut microbiota and improving metabolic profiles, such as insulin sensitivity. This can help mitigate obesity-related inflammation, which might exacerbate MS symptoms. The ketogenic diet also reduces oxidative stress and supports mitochondrial function, potentially improving cellular resilience in nerve cells.
Fasting-mimicking diets, which involve periodic calorie restriction, have shown in early research to lower inflammatory cytokines and promote immune cells associated with improved function. In animal models, such diets protected myelin-producing cells and encouraged remyelination, the repair of the protective nerve sheath. Human trials combining fasting-mimicking diets with Mediterranean diets have reported mild improvements in disability and quality of life, though larger studies are needed to confirm these effects.
Clinical trials comparing anti-inflammatory, ketogenic, and fasting diets in people with relapsing-remitting MS have found improvements in health markers such as blood lipids, weight, and blood pressure, but no significant reduction in brain lesions over 18 months. This suggests that while these diets may support overall health and reduce systemic inflammation, their direct impact on the neurological damage characteristic of MS remains uncertain.
Adopting an anti-inflammatory diet for MS involves focusing on foods that reduce inflammation and support immune balance, while minimizing processed foods, refined sugars, and unhealthy fats that can promote inflammation. The diet encourages a variety of colorful vegetables and fruits, healthy fats from fish and olive oil, and the use of anti-inflammatory herbs and spices. It is also important to maintain a healthy gut microbiome, as gut health influences immune regulation and inflammation.
In practice, people with MS may find that an anti-inflammatory diet helps reduce fatigue, improve energy levels, and enhance overall well-being. It can be combined with medical treatments and lifestyle changes like physical activity to provide a comprehensive approach to managing MS. Because MS symptoms and triggers vary widely among individuals, dietary adjustments should be personalized and ideally guided by healthcare professionals knowledgeable about MS and nutrition.
