Lectin Intolerance Symptoms and Myths About MS Diets

Understanding Lectins

Lectins are carbohydrate-binding proteins found in many plant foods like beans, grains, nightshade vegetables, dairy, etc. Some people claim that lectin intolerance causes inflammation and autoimmune conditions.

However, there is little evidence that lectins directly cause disease. While a small subset of people may experience symptoms from high lectin foods, they are harmless for most.

Common Symptoms Attributed to Lectin Intolerance

Those who do react to lectins may experience a wide array of symptoms including:

Digestive Issues

Symptoms like gas, bloating, diarrhea and nausea are commonly blamed on lectin intolerance. The lectins may irritate the gut lining for sensitive individuals.

Joint Pain

Some people report joint pain and arthritis flares after eating high lectin foods. The proposed mechanism is lectins triggering inflammation.

Headaches

Headaches are sometimes attributed to lectins. However, there are no studies proving lectins directly cause headaches or migraines in most people.

Fatigue

Because lectins can damage the gut lining, some feel fatigue and sluggishness results from inflammation or poor nutrient absorption.

Skin Rashes

Hives, eczema flares, and other skin conditions are often blamed on lectin intolerance. Lectins may trigger histamine release.

Brain Fog

Some claim lectins cross the damaged gut lining and cause inflammation in the brain, leading to brain fog symptoms like poor focus and difficulty thinking.

The Lectin-Free Diet

The lectin-free diet completely restricts high-lectin foods like:

• Legumes - beans, lentils, peas, soy
• Grains - wheat, quinoa, rice, oats
• Nightshades - tomatoes, potatoes, eggplants, peppers
• Dairy
• Eggs

Allowed foods include meat, fish, shellfish, nuts, seeds, most fruits and non-nightshade vegetables, oils, herbs and spices.

There is little proof that this very restrictive diet is needed for the majority of people. And it unnecessarily eliminates many nutritious foods.

Lectin Intolerance and Autoimmune Diseases

Those with autoimmune disorders like multiple sclerosis, rheumatoid arthritis and lupus are often told to cut out lectins. But there are several myths surrounding lectin intolerance and autoimmunity.

Myth 1: All Lectins Are Bad

Not all lectins are created equal. Some may be problematic for gut health while others are harmless. We eat lectins daily in healthy foods without issue.

Myth 2: Lectins Directly Cause Autoimmunity

There are no studies proving lectins alone trigger autoimmune disease. While they may exacerbate symptoms in some cases, other factors cause autoimmunity.

Myth 3: A Lectin-Free Diet Treats Disease

No evidence shows that simply removing dietary lectins can cure autoimmune conditions. Some people feel better on a lectin-free diet, but each disease must be treated based on its unique factors.

Myth 4: Everyone Should Avoid Lectins

For healthy individuals, cutting out nutritious foods with lectins is unnecessary. Those with autoimmunity should be tested first for lectin reactivity before making dramatic diet changes.

Multiple Sclerosis and Diet Claims

Various diets are promoted to people with multiple sclerosis (MS), but evidence is lacking for most:

The Wahls Diet

The Wahls Diet eliminates gluten, dairy and eggs while emphasizing vegetables, fruits and meat. But theres no proof this specific diet treats MS for most patients.

Paleo Diet

Some claim a Paleo diet high in meat and produce while cutting dairy, grains and legumes benefits MS. But more research is needed on Paleo for MS specifically.

Ketogenic Diet

Very low carb, high fat ketogenic diets are theorized to reduce inflammation in MS. But studies show mixed results and the diet is extremely restrictive.

Gluten-Free Diet

Unless you have celiac disease or confirmed gluten sensitivity, theres little evidence that going gluten-free benefits MS.

What Does Work for Multiple Sclerosis

While special diets may help some with MS, here are evidenced-based ways to manage symptoms:

Medications

Disease-modifying drugs like Tecfidera, Ocrevus, Gilenya, etc. are the most effective MS treatments. Work with your doctor to find the right medication.

Relapse Management

Corticosteroids treat acute MS relapses/flares. Plasma exchange and IVIG are other options.

Symptom Management

Physical therapy, exercise, and medication can help manage MS symptoms like fatigue, numbness, pain, weakness, etc.

A Healthy Diet

Eat a balanced whole foods diet with plenty of fruits, vegetables, lean protein, healthy fats and fiber. Stay hydrated and eat regular meals.

The Bottom Line

Those with lectin intolerance may benefit from reducing high-lectin foods. But theres no evidence that people with autoimmunity need to fully eliminate all dietary lectins, or that a lectin-free diet treats conditions like multiple sclerosis.

Work with your healthcare providers to find proven treatments and symptom management strategies for your individual case.
