Multiple Sclerosis and Food Intolerance: Uncovering Hidden Triggers, Including Alcohol

Links Between Food Intolerance and MS

Exploring the link between MS, digestive sensitivity, and allergic reactions—how food and drink choices could be affecting your health more than you realize. Living with Multiple Sclerosis (MS) is challenging enough without the added discomfort of food intolerance and allergic reactions. Yet, many individuals diagnosed with MS report experiencing gastrointestinal issues—frequent bathroom trips, bloating, or discomfort—after consuming common foods like bread, pasta, or pizza. For some, even a single drink of alcohol can provoke an inflammatory or allergic-like reaction. But what is the connection, and what can be done about it?

MS and the Gut-Brain Axis

Emerging research has shown that the gut-brain axis—the communication between your gut and central nervous system—plays a critical role in autoimmunity. MS, an autoimmune disease, is thought to be influenced by gut health. According to several studies, including those published by the National Multiple Sclerosis Society, intestinal permeability (commonly known as leaky gut) and gut microbiome imbalances are more prevalent in people with MS.

Foods containing gluten, lactose, or highly processed ingredients may provoke exaggerated immune responses in sensitive individuals. These reactions may not be full-blown food allergies, but food intolerances that still cause inflammation, fatigue, or digestive issues such as diarrhoea and cramping.

Alcohol and MS: A Hidden Aggravator

Alcohol, particularly wine and beer, contains histamines, sulfites, and gluten, all of which can exacerbate MS symptoms or mimic allergic reactions. Many MS patients have reported symptoms such as flushing, migraines, or digestive upset after drinking—even in small quantities. Alcohol can also disrupt medication absorption and dehydrate the body, worsening MS-related fatigue and bladder issues.

How to Identify Food Intolerances and Allergies

Even people without MS can experience adverse reactions to certain foods without knowing the root cause. Here are steps that anyone—especially those with chronic conditions like MS—can take:

• Elimination Diet: Temporarily remove common trigger foods (e.g., dairy, gluten, eggs, soy, alcohol) for 2–4 weeks, then reintroduce them one at a time to observe reactions.
• Allergy Testing: Blood or skin prick tests can help identify IgE-mediated food allergies.
• Food Sensitivity Panels: Though more controversial, these can detect IgG reactions, which some practitioners use to guide diet changes.
• Keeping a Food Diary: Tracking symptoms after meals can highlight patterns over time.

Safe Foods for MS and Sensitive Stomachs

✅ Generally Safe to Eat/Drink:

• Fresh fruits (e.g., berries, apples, bananas)
• Non-starchy vegetables (e.g., leafy greens, carrots, broccoli)
• Lean proteins (e.g., chicken, turkey, eggs, tofu)
• Fish rich in omega-3s (e.g., salmon, mackerel)
• Gluten-free grains (e.g., quinoa, brown rice, oats)
• Lactose-free or plant-based milks (e.g., almond, oat, coconut)
• Herbal teas and filtered water
• Cold-pressed olive oil, avocado oil

❌ Foods/Drinks to Consider Avoiding:

• Gluten-containing grains (wheat, rye, barley, found in bread and pizza)
• Dairy (milk, cheese, cream)
• Processed meats and fast foods
• Fried and greasy foods
• Sugar-heavy items and artificial sweeteners
• Alcohol (especially beer and wine)
• Caffeinated sodas and energy drinks
• Food additives and preservatives (e.g., MSG, sulfites)

What to Do If You Suspect a Problem

If you’re experiencing consistent digestive issues, fatigue after eating, or worsening MS symptoms, speak with a neurologist, dietitian, or GP who understands autoimmune conditions. They can work with you to tailor a personalised nutrition plan or refer you for food sensitivity tests. A well-balanced, anti-inflammatory diet may not only reduce digestive issues but also improve energy levels, cognitive clarity, and overall MS management.

Conclusion:

Diet is not a cure for MS, but it can be a powerful tool in managing its symptoms. Understanding how your body reacts to food and drink—including alcohol—may uncover hidden triggers that could otherwise go unnoticed. For those living with MS, this awareness can make a tangible difference in daily quality of life.
