Overview: why is diet important?

OMS incorporates MS diet recommendations that are scientifically researched and play an important role in managing MS. 

Dairy and MS

Research shows a high correlation between MS and dairy products, because of the high saturated fat content and specific proteins in cow’s milk.

Role of fats in MS

Several long-term studies show a close connection between saturated fats and the development and progression of MS.

Guide to understanding fats

There are many different types of fats, some are ‘good’ for the immune system, others are neutral and some are ‘bad’.  Here’s a useful list to help you figure out which is which.

What to eat


Switching to a plant-based, wholefood diet that is rich in omega-3 while excluding dairy and minimizing saturated fat intake is critical in recovering from your symptoms and living a long, healthy life.

The Overcoming Multiple Sclerosis diet provides a wide variety of foods to enjoy, including fruits, grains, fish and seafood and dairy alternatives. Check what you are encouraged to eat and what should be avoided on the OMS diet.

Following a healthy diet is important in improving symptoms and preventing the progression of multiple sclerosis.

What can I eat instead?

Replacing dairy

Hints and tips on what you can use in recipes to replace dairy products like butter, milk and cream. There are so many dairy-free options available that avoiding dairy doesn't need to mean that you miss out on the food you love.

Replacing meat

If you're new to OMS, finding meat substitutes that are OMS-friendly can be a little confusing. We've put together some suggestions of options to replace meat in meals, that are high in protein and also OMS-friendly.

Replacing eggs

While egg white can be eaten when following the OMS diet recommendations, egg yolk is not recommended on the OMS program due to saturated fat content. Some people choose to omit eggs altogether, for example, if they have a plant-based diet.

Eat in moderation

Foods containing monounsaturated (neutral) and polyunsaturated (good) fats such as avocados, seeds, nuts and oily fish should be consumed in a balanced way when following the OMS Program.

Omega-3 Supplementation

Overcoming MS recommends people with MS to take 20-40 mls of flaxseed oil per day to increase the amount of omega-3 in their diet.

Ultra-processed foods

Overcoming MS suggests minimising the amount of ultra-processed food you eat as much as possible.

Cooking Techniques

It is not necessary to learn lots of new cooking techniques or dramatically change the way you cook when following the OMS program. The only thing that may need altering is the amount of fat and oil you use in your cooking.

Which oils?

What oils can I consume as part of the OMS diet? All naturally occurring oils are in fact a blend of saturated, monounsaturated and polyunsaturated fatty acids. It is this makeup that determines which are suitable for you to have on the OMS diet, which is low in saturated fat.
