Diet and Multiple Sclerosis
Many people with multiple sclerosis (MS) want to know if changing what they eat can help. Diet is one part of your health you can control. Research suggests it may affect symptoms like fatigue, and staying at a healthy weight matters. But so far, no single diet has been proven best for MS.
Does Diet Affect MS?
The science is still early. A poor diet is linked to a higher risk of developing MS, and obesity is linked to more disability, so eating well and staying at a healthy weight are worth the effort. But diet is not a substitute for your disease-modifying therapy, which is what reduces relapses and long-term disability. Think of healthy eating as one part of your overall care, not a replacement for treatment.
Popular Diets You May Have Heard About
The Swank diet. Developed by Dr. Roy Swank, this low-fat diet limits saturated fats such as butter, cheese, and red meat. It was one of the first diets studied for MS.
The Wahls Protocol. Created by Dr. Terry Wahls, who has MS, this diet limits certain plant proteins thought to cause inflammation. Studies testing it are still underway.
Intermittent fasting. This means cycling between eating normally and eating very little. Early research is looking at how it affects the gut bacteria that may influence MS.
The ketogenic diet. This high-fat, low-carb diet has long been used for epilepsy. Small early studies in MS showed some improvement, but more research is needed.
Making a Change That Lasts
Changing your diet is a lifestyle change, and it takes real commitment. It is often easier with support from family, since meals affect the whole household. Small, steady improvements are more realistic than a strict overhaul, and even small changes may help. Pairing better eating with regular exercise gives you the most benefit.
When to Talk to Your Provider
There is no single MS diet, so talk with your health care provider before making big changes, especially if you have other health conditions. Your VA team, including a dietitian, can help you find an eating plan that fits your health and your life. And keep taking your prescribed MS treatment - diet works alongside it, not in place of it.
