How Diet Shapes Multiple Sclerosis: What Recent Research Reveals

 

Living with multiple sclerosis (MS) means navigating not only symptoms and treatments, but also lifestyle choices that can influence the course of the disease. One of the most powerful—and often overlooked—factors is diet. A recent review published in Nutrients (MDPI, 2024) highlights how the foods we eat can either fuel inflammation or help calm it, shaping the progression of MS.

Why Diet Matters in MS

MS is an autoimmune condition where the immune system attacks the protective covering of nerves. While genetics play a role, environmental factors—especially nutrition—can tip the balance between inflammation and healing. Researchers now see the gut–brain axis (the connection between gut health and the nervous system) as a key player in MS.

Fats: The Good, the Bad, and the Protective

• Saturated fats (found in fatty meats, butter, coconut cream/milk, processed foods) tend to worsen inflammation and are linked to more active MS.

• Monounsaturated fats (like olive oil and avocados) help reduce oxidative stress and support gut health.

• Omega-3 fatty acids (from fish, flaxseed, walnuts) are strongly anti-inflammatory and may lower MS risk and improve outcomes.

• Trans fats & ultra-processed foods disrupt gut bacteria and fuel inflammation.

 Carbohydrates: Quality Counts

• Refined sugars and white flour spike blood sugar and drive inflammation.

• Whole grains and complex carbs provide steady energy and support gut health.

• Fiber is especially important—it feeds beneficial gut bacteria that produce short-chain fatty acids (SCFAs), which strengthen the gut lining and calm the immune system.

Proteins: A Mixed Picture

• Red and processed meats may promote inflammation.

• Dairy and gluten show mixed evidence—some people report sensitivity, but research is not conclusive.

• Plant proteins (beans, lentils, soy) are generally more supportive of an anti-inflammatory diet.

 Fiber: A Star Player

Fiber-rich foods (vegetables, fruits, legumes, whole grains) consistently show protective effects in MS. By nourishing gut bacteria, fiber helps produce SCFAs that:

• Strengthen the gut barrier

• Reduce harmful immune activity

• Support regulatory T cells (which keep inflammation in check)

Gut Microbiota: The Hidden Link

People with MS often show gut dysbiosis—an imbalance in gut bacteria. Diet is one of the strongest ways to restore balance. Eating more fiber, omega-3s, and plant-based foods helps cultivate a healthier microbiome, which in turn reduces inflammation in the brain and spinal cord.

Practical Takeaways

If you’re living with MS, consider these dietary shifts:

• Favor: olive oil, fatty fish, nuts, seeds, whole grains, legumes, fruits, vegetables

• Limit: saturated fats (butter, fatty meats, coconut cream/milk), refined carbs, sugary foods, ultra-processed snacks

 Final Word

This research reinforces what many people with MS already sense: food matters. While diet isn’t a cure, it’s a powerful tool to support your body, reduce inflammation, and potentially slow disease progression. More clinical trials are needed, but the evidence so far points toward an anti-inflammatory, fiber-rich diet as a smart choice for living well with MS.

Foods to support the immune system - part 3

Cruciferous vegetables are the gold standard in immune-boosting vegetables.

Watch this video to see the great range of Cruciferous vegetables. 

Although all vegetables have nutrients and some protective powers, for these vegetables, it’s off the charts. Cruciferous vegetables, from the Brassica family, have a special chemical composition: They have sulfur-containing compounds that are responsible for their pungent flavors. When they’re broken down by biting, blending, or chopping, a chemical reaction occurs that converts these sulfur-containing compounds into isothiocyanates (ITCs). ITCs prevent and knock out cancer and have infinite proven immune-boosting capabilities.
They contain antiviral and antibacterial agents that keep you disease free. Adding the following cruciferous vegetables to your daily plate is like taking an anticancer pill: arugula, beet greens, bok choy, broccoli, brussels sprouts, cabbage, cauliflower, collards, horseradish, kale, kohlrabi, mustard greens, radishes, red cabbage, turnip greens, or watercress. Cruciferous vegetables are often called cole crops by people in North America and brassicas by people in the United Kingdom.

Here is a great book that provides recipes on cooking with these healthy immune assisting vegetables: 

Brassicas: Cooking the World's Healthiest Vegetables: Kale, Cauliflower, Broccoli, Brussels Sprouts and More
A cookbook showcasing 80 recipes for the most popular of the world's healthiest vegetables-kale, cauliflower, broccoli, brussels sprouts, cabbage, leafy greens, and more-tailored to accommodate special diets such as gluten-free, dairy-free, vegetarian, and vegan.
For a long time, brassicas had a mixed reputation. While a small group of people staunchly adored them, most Americans were not as fond of the vegetables formerly known as "cruciferous" (who doesn't remember a plate of stinky boiled cabbage or President Bush's condemnation of broccoli?). But in recent years, a transformation has occurred. Kale has taken the world by storm and there's hardly a restaurant left that doesn't have cauliflower on the menu. The rising popularity of brassicas is not only due to their extraordinary health benefits and "superfood" status, but also the realization that they can taste delicious when properly prepared.

About all the minerals

Supplements for immune health

When we think of supplements we will automatically think of vitamins but we should not forget about minerals as some of them have been proven to help the immune system, specifically Iodine, Selenium and Zinc.

Besides immune health iodine is needed for thyroid health.
Selenium helps prevent cell damage and reduces infection.
Stress and pollution deplete our body of zinc.

Iodine is found in iodized salt, milk, egg yolks and fish.
Zinc and Selenium are both found in fish, meat, poultry, dairy and whole grains.
