Diet and MS

It doesn’t matter if you’ve been living with MS for a long time or you’re newly diagnosed, diet and its impact on MS continues to be a topic of interest in the community.

You may have received advice from well-meaning friends and family; and there’s often new articles or blogs on how diet and particular vitamins affect MS but it can be hard to know what works and what’s been proven.

There are some simple key points that you can take away to help you to look after yourself as best you can. You can use this information to make positive lifestyle decisions and aim to be as well as humanly possible.

Things to consider

Dietary changes may have a positive impact on your MS but what we know for sure is, they will impact your general health – and the healthier you are the better you will manage with the things that MS throws your way.

If you’re thinking about changing your diet, there’s a couple of questions to consider as you go:

What am I expecting from a dietary change?

Can I stick to it (how will it impact your social life)?

Are you trying to manage MS or keep other things away?


The “keeping other things away” point is a very important one. Living with MS is challenging enough without having to managing another illness.

Reviewing and managing your diet can be more so about making sure you’re the healthiest version of yourself to avoid any other illness.


Good nutrition is important for everyone

Making positive changes to your diet and nutrition is good for anyone with MS. Most of us have some room for improvement in our diet to avoid potential future health complications.

When we talk about other health complications, this can include heart disease, stroke, Type 2 diabetes, Osteoporosis which in most cases are preventable. It is important to keep your body healthy to avoid health complications like this in addition to your MS.

As a person with MS, the development of any vascular comorbidity such as heart disease, stroke, Type 2 diabetes and osteoporosis, can lead to an increased progression of MS.  For this reason, it is important to consider your nutrition choices and maintain a healthy body weight to reduce the risk of these conditions.

What food should I avoid?

One thing we know for sure, is that salt is not good, whether you add it yourself or it’s in the food you eat.

High salt diets have an impact on MS over a long period of time as it triggers an inflammatory response. It is not just the inflammatory response though; it is also salt’s impact on other health complications like heart disease etc.

Alcohol and Caffeine often come into the debate as well and the advice seems to be consistently changing. With alcohol and caffeine simply apply the moderation principle …. everything in moderation.

Easy to make recipes

Is there a diet to help with MS?

There are a number of well-known people living with MS, such as Matt Embry, Terry Wahls, and George Jelinik, who have developed widely publicised dietary recommendations for MS.  Whilst none of these specific diets have been clinically proven to benefit people with MS, there may be some people who experience improvements after making adjustments to their diet.


We have a list of popular MS diets below:

Dietary changes can take months or even years before you start to see a benefit. MS affects everyone differently and what works for one person may not work for another. For dietary advice and guidance specific to your requirements it is best to speak with an accredited dietitian or nutritionist.

Summing up

By staying fit and healthy, you can avoid any other condition that might make managing your MS more difficult.

As for diets, the scientific evidence is debatable for any specific MS diet. If you’ve spoken to your neurologist or GP about this, you may not have received an enthusiastic response but that doesn’t mean there isn’t value in these diets.

For the diets listed, there is nothing unsafe. If you try it and you don’t feel any different then perhaps it’s not for you. If you notice a benefit and you feel better from a diet, then it can’t be a bad thing.
