Overcoming MS Diet FAQs

Step one of the OMS Program focuses on diet. Find answers to your questions about meat, dairy, flaxseed oil supplementation and more.

What are some satisfying go to snacks?

  • Rice or oat cakes topped with avocado and red pepper / Nush cream cheese and tomato slices / almond butter and apple or pear slices
  • Nakd bars
  • soy/almond yoghurt topped with mixed berries and seeds
  • olives and few nuts
  • a piece of fresh fruit with nuts
  • crudités with houmus / tahini dip / guacamole

What is the maximum amount of saturated fat recommended per day on the Overcoming MS diet to be classified as a low saturated diet?

Less than 16g.

How similar is the Mediterranean diet to the Overcoming MS diet? Would the Mediterranean diet achieve the same results?

Both diets are plant-focused and rich in variety of fruit and vegetables, limit processed foods and include regular servings of plant proteins like beans, lentils, nuts, and seeds. Evidence shows that the Mediterranean diet is beneficial for autoimmune conditions, namely rheumatoid arthritis. However, the Mediterranean diet still includes dairy, meat and has less emphasis on Omega-3 consumption. The Overcoming MS is a modification of this diet with specific tweaks (dairy-free, high Omega-3 intake, low saturated fat) to support more specific challenges of MS.

Can I eat tinned salmon?

Absolutely! Any tinned fish is perfectly fine on the Overcoming MS Program and can be a cheaper way to get oily fish like sardines, mackerel, pilchards into the diet.

Are there particular foods that should be avoided with certain drugs such as Tysabri infusions?

Drugs for MS do not work in the same way as some chemo drugs which aim to kill certain cells. Often with chemo, patients are advised to avoid foods like ginger or turmeric that may protect cells from the destructive action of chemo medication. THIS IS NOT THE CASE WITH MS MEDS. Grapefruit is often contraindicated with certain drugs eg statins due to the effect it can have on liver detoxification. AGAIN, THIS IS NOT THE CASE WITH ANY OF THE MS DMDs.

Are there any guidelines about the amount of soya/tofu products that it’s ok to regularly eat?

Not as such – but the whole of Asia is eating significant amounts of soy-based products on a daily basis and suffer with lower cancer rates, less menopausal symptoms and NO adverse effects. 1 -2 servings a day is absolutely nothing to be concerned about. Eat a variety of foods with soy and avoid the less processed versions of soy-based alternatives to limit food chemicals. Organic soy and non-GMO soy are also worth looking out for.

Do you suggest family members including toddlers/young children follow the Overcoming MS diet too?

It is absolutely fine for all family members to follow the Overcoming MS diet whatever their age. However, it is not so necessary that you are as strict with them. For example, school lunches, tea parties, play dates etc will all be much easier and less stressful for you if they can enjoy the range of foods on offer. However, following the Overcoming MS diet at home will also ensure they are getting a wholesome and healthy diet most of the time.

Dark chocolate has crept back into my diet. Is the issue with dark chocolate that the cocoa butter is high in saturated fat?

Yes – dark chocolate contains cocoa butter which is a source of saturated fat that will drive inflammation. Being dark, the chocolate has no added milk, and the darker the chocolate the higher the cocoa butter level so 85% contains more saturated fat than the 70%. Cocoa and cacao powder however can be enjoyed on the overcoming MS diet.

Since following the Overcoming MS diet I've lost some weight. What advice do you have to stop losing more?

Be sure to get sufficient proteins and remember the Overcoming MS diet is a low SATURATED fat diet, not a low FAT diet. Get plenty of the good fats in your diet – nuts, seeds, oils (dressings, flax on cooked food / soups / curries etc), and oily fish 3x a week if you are eating fish.

Is there an increased risk of osteoporosis by eliminating dairy?

The abundance of calcium-rich plant foods means that in the Overcoming MS diet there is plenty of calcium provided. What’s more, the calcium in plant foods is often combined with other vitamins and minerals that aid its absorption and help to build strong bones e.g. Vitamin K, Magnesium and Boron. Populations where dairy consumption is highest, also exhibit the highest cases of osteoporosis. Both exercise and Vitamin D intake on the overcoming MS program will help guard against osteoporosis too.

There seems to be a lot of evidence to suggest gluten is inflammatory. What is the evidence around this with MS?

To date the studies into gluten as a contributor to MS are comparatively few. At the moment, there is certainly not enough evidence to suggest people with MS need to avoid gluten. In fact, it can be more detrimental than good to cut gluten out of the diet without good reason and without an allergy (coeliac disease) or an intolerance (Non-Celiac Gluten Sensitivity – NCGS).

Can I heat nut butters?

There is no harm in heating nut butters. Nut butters (without added oil) contain high levels of the neutral monounsaturated fat which makes them more stable at higher temperatures. Vegetable oils – such as sunflower oil – have much greater concentration of polyunsaturated fats which can spoil at a lower temperature than is tolerated by monounsaturated fats. Be mindful of nut butters with added oils.

If heating nut butters as part of a recipe, avoid high temperatures e.g. more than 200C.

Should I eat peanuts and other nuts?

Peanuts are defined as a ground nut and not recommended due to their higher saturated fat content and the fact that they are usually roasted in oil or dry roasted.

Enjoy other nuts instead – walnuts, almonds, pecans and pistachios. Walnuts have the most omega 3 content.

Brazil nuts, macadamias and cashew nuts contain more saturated fat than some other tree nuts e.g. almonds or hazelnuts so will require a smaller potion size. 

Can I eat nut butters?

Nut butters and nuts contain comparable amounts of fat, but some nut butters have added oils which would obviously affect this. Our understanding on the difference between butter/nut is that to make the butter, you roast the nut thereby exposing the potentially delicate oils to heat.

  • Peanuts are a ground nut and not recommended due to their higher saturated fat content. Peanuts saturated fat content in peanut butter is comparable to cashew and less than macadamia for example. The issue with peanuts is the contamination of aflatoxins and moulds, which is why this is best limited.
  • Natural nut butters you can consume include almond, macadamia and cashew nut butter.
  • Always choose good quality nut butters without additional oils or a number of other added ingredients. Some brands of nut butters use cheap, processed oils like palm oil, or hydrogenated fats, and may include high amounts of unnecessary added sugar.
  • Enjoy nut butters in small amounts; spread thinly on wholegrain toast for breakfast, or maybe as a snack on wholegrain crackers etc. They may also serve as a useful ingredient in recipes as a fat replacement.
  • Many peanut butters and nut butters contain added oils and sugars to improve their texture and taste. Ensure this is consumed in small-moderate amounts and always check labels to avoid those products with added oils and sugars.

Which oils can I use?

  • Flaxseed oil consumption is encouraged, up to 40ml per day. 
  • High-quality extra virgin olive oil is healthy in moderate amounts and is the oil recommended for using in home cooking.
  • Some details to be mindful of when purchasing high-quality extra virgin olive oil:
    – Oils with a cloudiness at the bottom are high quality being a first press
    – Avoid buying oil in plastic bottles – look for glass or tins etc.
    (This can be expensive, it would be an idea to do a quick search at your local supermarket to find reasonable and affordable options).
  • Sunflower and rapeseed oils are higher in omega 6 polyunsaturated fat and so should be consumed only moderately.
  • If you see sunflower or rapeseed oils on an ingredient list and they feature only in small amounts in those shop-bought foods, then it is ok to include these produces in small amounts & less frequently for convenience. However, it is unlikely these convenience foods are using the cold-pressed versions of the oils, which are the  version that should be considered using in your home food preparations.
  • Some unrefined seed oils (sesame, rapeseed, pumpkin) are also fine in small amounts, and may be used to ‘season’ food after cooking.
  • Avoid completely: palm oil and coconut oil, vegetable oil and highly processed oils (e.g. canola, soybean, cottonseed, corn oil).
  • Don’t fry in oil.

Rather than consuming fresh flaxseed oil, is it possible to take it as a supplement instead (ie in capsule form)?

There are two issues with this. Firstly, the instability of omega 3, whether from fish oil or flaxseed oil, renders it hard to keep fresh in a plastic container on a shop shelf, probably for prolonged periods. You can taste immediately if your bottled flaxseed oil has ‘gone off’ – it will be bitter and rancid – but you will miss this warning taste if it is contained within a capsule.

Secondly, and assuming the capsules do contain fresh oil, you will find typically around 1000mg of oil per capsule – around 700mg of ALA (omega 3). A tablespoon of flax oil contains around 7,000mg of ALA. You would therefore have to take quite a few capsules to get the same amount of valuable omega 3 to match the quantity provided in 2-3 tablespoons (20-40ml) of flaxseed oil recommended on the OMS program. This can get quite expensive, as well as cumbersome.  

What is the Swank diet?

The Swank Diet is a low saturated fat diet which has been found to majorly improve the health of people with MS. It is based on Professor Roy Swank’s 34-year study between 1949 and 1983 which assessed the impact of the diet on 150 PwMS. It found that, for people with MS, there is a positive link between limiting saturated fat intake to 15g per day and fewer relapses, less disability and improved quality of life. Find more detail in our Diet section.

Can I cook with oil?

People with MS should be careful when cooking with oil, as high temperatures can alter the oil’s structure, forming harmful toxic products. This is particularly the case when frying with oil, as the temperature of the pan gets to very high levels.

  • Frying with oil should be avoided if possible, instead, sauté your foods in a little water or stock, soy sauce or white wine, or other oil-free liquids so you can still continue to make your favourite dishes.  
  • People with MS can consume food with oil in it that has been baked. This is because baking uses a lower heat than frying, and takes place over a longer period – therefore, the oils do not break down in the same way. Just remember that you should bake with extra virgin olive oil, flaxseed oil can never be heated. A safe temperature to bake/roast at, on the OMS diet, is 180 degrees celcius (356 F).

There is lots more information about oils elsewhere on this website including: which oils are recommended and OMS-friendly cooking techniques.

Can I drink alcohol?

Yes, all types of alcohol are OK in moderation for people with MS. Moderation means not more than two standard drinks a day, with at least two alcohol-free days a week. Alcohol in excess is harmful to health, and moderation is required for reasons other than MS.

Are there caffeine restrictions on the OMS Program?

There are no specific restrictions about caffeine included in the OMS Program. However you should follow standard health advice about consumption of caffeine – ‘in 2015 the European Food Safety Authority (EFSA) published their Scientific Opinion on the Safety of Caffeine, advising that caffeine intakes from all sources up to 400 mg per day and single doses of 200mg do not raise safety concerns for adults in the general population.’ Read more here.

Can I eat sugar?

There is no compelling evidence linking sugar to worsening MS symptoms, however through following a plant-based diet most people naturally reduce the amount of sugar they consume. You can follow the standard dietary guidelines (e.g. WHO recommends a maximum of 5 to 10 teaspoons of free sugars per day). 

You may want to consider using unrefined sugar such a raw honey, dates, mollases etc. 

Should I exclude gluten from my diet?

If you are not intolerant to gluten, it is fine to continue eating gluten when following the OMS Program. 

The most severe form of gluten intolerance is celiac disease. Here, people develop serious digestive system disorders due to an immune response to the gluten in wheat. One might expect, if gluten were a key ingredient to avoid in MS, that people with MS might have a higher incidence of celiac disease. Or vice-versa: that people with celiac disease might have a higher incidence of MS. However the data from several studies shows that there is not a higher incidence of celiac disease in those with MS or vice-versa. 

Additionally, there is no clear biochemical similarity between part of the gluten compound and myelin, as far as we are aware. Finally when we run the epidemiological cross-check, populations that consume wheat do not appear to have a higher incidence of MS than other populations.

How do I avoid losing weight when starting the OMS diet?

Weight loss is a common issue for people with multiple sclerosis when they start the Overcoming MS Program.

The transition from a diet that is high in saturated fats and processed foods to one that is whole food plant-based can have a big impact. Although it is important to reduce saturated fat intake, we should not cut out fats altogether as they perform many important functions in the body.

Instead, we should change the type of fats we consume. Avoid saturated fats which usually come from animal products such as meat and dairy. Oily fish such as salmon, mackerel and sardines are good sources of healthy fat and can be consumed approximately three times per week. Look to consume plant-based sources of fat such as avocado and nuts on a regular basis as well as taking 20-40ml of flaxseed oil daily.

People with MS should also take care to maintain a regular level of carbohydrate intake, as reducing this can lead to weight loss. Wholegrain rice and wholegrain pasta are recommended sources of carbohydrates.

If in doubt, registered dieticians can provide detailed information and help put together a balanced way forward.

When you start the Overcoming MS program, you will lose a little weight and then after a while this will usually stabilize as your body becomes used to the diet.

Is 90% cocoa dark chocolate OK to eat?

No, people with multiple sclerosis should not consume dark chocolate. The problem with chocolate is the cocoa butter, which is very high in saturated fat. Worse, there is an allowable limit of 15% altered fats in cocoa butter.

To explain: 100% chocolate contains about 50% overall fat – about 1/2 of the total fat is saturated. That means 100 grams of chocolate contains 50 grams of fat (25 grams saturated). 90% chocolate contains 90% cocoa and 10% sugar (45 grams fat and 22 grams saturated in a 100 gram chocolate bar). Some countries may allow up to 15% fat replacement (usually palm fat) of the cocoa butter. Cocoa nibs (also referred to as cacao nibs) are 100% chocolate and contain the full amount of fat as a bar of 100% chocolate (50% fat and up to 25% saturated).

If you want to add some chocolate flavour to a recipe try cacoa nibs – small pieces of crushed cocao beans which can add an intense chocolate flavour to recipes or high-flavonoid (70-85%) cocoa/cacoa powder. Be very mindful in consuming nibs. High flavonoid (70-85%) cocoa/cacao powder is fine to consume. 

Why is coconut milk/oil not recommended on the OMS Program?

Often hailed as a healthy oil in the media, coconut products actually contain a high percentage of saturated fat, which are excluded on the OMS program. A key issue with saturated fats is their melting point. If the melting point of a fat is above body temperature (37 C), then it will essentially behave in body cell membranes like a solid fat, making the cell membranes rigid, inflexible and sticky, thereby encouraging degeneration and inflammation. The common fats in coconut are lauric acid (with a melting point of 44.2 C) myristic acid (53.9 C) and palmitic acid (63.2 C). These fats are solid at body temperature and are likely to significantly worsen MS. We do not recommend them in any quantity. Instead, consume monounsaturated oils such as extra virgin olive oil.

Can I consume low fat dairy products on the OMS diet?

It is not recommended to consume low fat dairy products on the OMS program as they still contains dairy – therefore butrophilin – the protein in cows milk which we advise avoiding if you have MS. Replace dairy products instead with plant-based alternatives such as soy, oat or almond. Processed ‘low fat’ products often have added sugar and other unhealthy ingredients, it is better to consume food that are naturally low in fat.

Can I drink lactose-free milk on the OMS program?

Lactose-free milk is a dairy milk which has added lactase, and is made for people who lack the enzyme that breaks down lactose, which can cause lactose intolerance. It is not recommended to consume ‘lactose-free’ milk on the OMS program as it still contains dairy – therefore butrophilin – the protein in cows milk which we advise avoiding if you have MS. Replace dairy products instead with plant-based alternatives such as soy, oat or almond milk.

Are goat/sheep milk products advised on the OMS Program?

No. Cow, goat and sheep milk all appear to contain the same offending protein, butyrophilin, which causes harm to the immune system. Research has found that the proteins in a range of animal milks are similar to bovine butyrophilin (reference below). 

Reference: Heid HW, Winter S, Bruder G, Keenan TW, Jarasch ED. Butyrophilin, an apical plasma membrane-associated glycoprotein characteristic of lactating mammary glands of diverse species. Biochim Biophys Acta 1983;728:228-38

Where do I get calcium if I exclude dairy from my diet?

There are many good sources of calcium encouraged in the OMS diet including: fish where you eat the bones, nuts, green leafy vegetables, fortified non-dairy drinks, tofu, tahini, pulses and dried fruits. Provided you are eating a balanced diet, you should be able to get the 700mg recommended per day for adults 19 to 64.

One problem with calcium in Western societies is the lack of sunlight. Sunlight results in vitamin D being produced in the body, and vitamin D’s main job is to absorb calcium from the diet. With adequate vitamin D from sun or supplements, there is no problem with inadequate calcium. Osteoporosis is also unlikely for people who get enough vitamin D.

What can I use instead of butter?

For butter you can get a similar rich flavor and texture from plant-based oil or even mashed bananas. As a rule, substitute oil for butter in recipes – especially those that instruct you to melt the butter first.

Use 82% oil for the butter called for in a recipe and add some kind of binding agent (a tbsp. of rice flour or ground flax seeds).

For sweeter recipes like muffins, use a fruit or vegetable puree (eg: apple puree) as a replacement for the butter. Measure equal quantities.

How much saturated fat can I have daily?

The conclusion of Roy Swank’s study was that people with MS should not consume more than 10-15 g of saturated fat per day. The Overcoming MS program is designed so that you don’t have to count though. By eating a wholefood, plant-based diet plus seafood and avoiding meat, dairy and processed foods, you won’t be over the limit.

Why is soy allowed on OMS but not on other MS diets?

Legumes, including soy, are extremely healthy foods and are full of protein. Consuming legumes is useful for people not eating animal products.

They have been used for centuries by many societies, and there is no clear documentation of any health problems associated with their use. Some have suggested that people with immune-based diseases should avoid them, but there appears to be no strong basis for this suggestion.

Soy in particular would appear to have many advantages over dairy products, and most studies suggest better health outcomes for those consuming soy products regularly.

How much omega-3 should I take?

This is actually not an exact science and is quite complex. Our recommendations come from a synthesis of many sources. Omega-3s are helpful in MS in two ways:

  • In a structural way, in forming part of the body’s cell membranes and making them more pliable and soft (due to their low melting points)
  • In an immune way, as they are the precursors of the cytokines and eicosanoids that the immune system Th2 cells secrete to dampen down inflammation

If one is eating an ultra-low saturated fat diet, as with the OMS program, it doesn’t take much omega-3 to get a structural benefit; i.e. an improvement in the pliability and resilience of cell membranes. It takes quite a bit more to get the optimal immune benefit.

That is why the standard dose (often recommended by specialists) of 3g a day of fish oil is inadequate; it doesn’t really provide the immune system benefit. In studies where they have measured the dose of omega-3s to get the optimal immune benefit, they have used standard-strength fish oil.This has 120mg DHA and 180mg EPA in each 1,000mg (1g, or 1ml) capsule (i.e., a total of 300mg DHA/EPA combined).

The studies suggest that a dose of around 20g (20 ml or 20 capsules) of standard-strength fish oil gives you the optimal immune benefit.

You can of course get refined fish oil where these constituents (the actual total omega-3s DHA and EPA) are concentrated, and so this dose needs to be adjusted accordingly. For instance a super-strength fish oil (240mg DHA and 360mg EPA /  capsule), you would need to take 10 capsules.

The calculation for flaxseed oil is much more complicated, as it contains ALA, which is converted in the body to DHA and EPA, but the percentage conversion varies from person to person (see pages 288-290 in the OMS book).

To simplify matters, we recommend the same dose (20- 40mls) 

One of the issues with all oil supplements is that they contain saturated fat; fish oil contains around 30% and flaxseed oil around 9%.

The figure of 20 mls (20g, 20 capsules) of standard fish or flaxseed oil we recommend is a minimum to achieve the immune benefits, but more can be taken, particularly if oil intake from other sources is very limited. The body really does need some oil, and people can get dry skin and hair and lose energy if there is too little fat in the diet. If you feel you need more oil, then increase your flaxseed oil dose, because it contains the least saturated fat.

Many people prefer to stop counting, and they just use flaxseed oil regularly on their pasta, baked potatoes, salads, etc. (after cooking of course).

It is quite delicious used in this way once you are used to it. In reality, people probably get more like 30-40mls/day using flaxseed oil in this way, and that is still in accordance with the OMS program, and may well result in more energy as well as a potent structural and anti-inflammatory effect.

What is flaxseed oil?

Also known as linseed oil, flaxseed oil is a plant-based source of omega-3 and is the preferred source of omega-3 supplementation on the OMS Program. Ideally, cold-pressed flaxseed oil should be purchased as it is likely to be more fresh than flaxseed capsules. Flaxseed oil can be used as a salad or pasta dressing and can also be added to smoothies or taken by the spoonful. OMS recommends 20 – 40 ml per day.

It should be added after food is cooked, not heated directly during cooking as this damages the nutritional properties of the oil. It is best stored in a fridge, and should be used within six weeks of purchase.

You can tell when it has gone out of date when it develops a slight bitter taste. It can be frozen and then defrosted slowly in the fridge

Also known as linseed oil, flaxseed oil is a product that is highly-recommended as part of the Overcoming Multiple Sclerosis diet.

Can I get too much omega-3?

A key part of the OMS diet is encouraging omega-3 intake and cutting down omega-6 to reduce inflammation.

Taking up to 3,000–5,000 mg of omega-3 per day appears to be safe. Remember that most sources of omega-3 will contain other types of fats (fish oil contains around 30% and flaxseed oil around 9% saturated fat), therefore you should limit the amount you have to reduce intake of these other fats. 

Omega-3 rich foods include oily fish and flaxseed supplements. We recommend a maximum amount of flaxseed oil of about 40 ml per day (about three tablespoons) and recommend eating oily fish no more than 3 times a week.

Can I use ground flaxseed instead of flaxseed oil?

  • Using whole or ground flaxseeds can be a healthy addition to the OMS program for the protein, fibre and other nutrients the seeds contain. However, in order to extract their oils, flaxseeds must be ground, otherwise they simply pass through your body intact.
  • Once ground, the concentration of oil present will still be too low to meet the high required daily beneficial amount of flaxseed oil as recommended by the findings of the HOLISM study.
  • If you would like to use ground flaxseeds for a healthy addition to baking, smoothies or other recipes, they should ideally be freshly ground – a coffee or spice grinder is good for this. Surplus ground flaxseeds should be stored in the fridge to prevent the oils in them becoming rancid.
  • Avoid buying pre-ground flaxseeds or LSA (linseed-sunflower-almond meal), which are unlikely to be fresh enough and may already be rancid.

How much flaxseed oil do I need each day?

People with MS should consume between 20ml and 40ml (approximately one to two tablespoons) of flaxseed oil per day.

Can I get all my RDA of omega-3 through flaxseed oil?

Yes. Our recommendation is to take 20-40ml of flaxseed oil each day as the most efficient way of obtaining omega-3 requirement. You can do this alongside consumption of oily fish if you wish to (3 times per week). 

Can I use Lyprinol instead of fish oil for omega-3 intake?

It is best to use therapies that have been shown in trials to be helpful in MS, or that have shown equivalence with such therapies in well-designed clinical trials. For the New Zealand green-lipped mussel extract (Lyprinol), it is too early to tell, as most studies are in experimental models rather than patients, but the effect is likely to be small.

Can alpha linolenic acid (ALA) in flaxseed oil be converted into EPA and DHA in the body?

There has been discussions about whether flaxseed oil is “as good” as fish oil. This is because the fatty acid in flaxseed oil, alpha linolenic acid (ALA), needs to be converted in the body to the fish oil fatty acids, eicosapentaenoic acid (EPA) and then docosahexaenoic acid (DHA).

The 15-20ml daily dose suggested by OMS of flax oil will provide a conversion of around 2-3% to ALA (Udo Erasmus in his book “Fats That Heal, Fats That Kill” does a good calculation on this. Erasmus quotes a figure of 2.7% per day.)  This would supply enough ALA to make about 378mg of EPA, equivalent to what is in two 1,000mg fish oil capsules.

If you took straight fish oil capsules then you wouldn’t need to convert ALA to EPA and DHA, so yes whilst you could take a smaller amount of capsules (compared to flaxseed capsules, not flaxseed oil). 

  • However, you wouldn’t for the same benefits as taking flax oil, as per the HOLISM research (which showed no benefit from fish oils, but a 60% release rate reduction with flax oil). This is because the oil in a capsule will never be of the same standard as a fresh cold-pressed oil in terms of production, freshness or storage.
  • Omega-3 supplementation using flaxseed oil has none of the chemical toxins like mercury in fish oil (and to questions about the sustainability of our fish stocks), and also EPA made this way is fresher, in the body every day.
  • Another bonus: there is minimal saturated fat intake this way, as fish oil contains quite a bit of saturated fat. 

If omega-6s promote inflammation, should I omit them altogether?

For optimal health, it is important to have both omega-3 and omega-6. These are essential fatty acids; health cannot be sustained without them. The right omega-6 to omega-3 balance ranges from about 2:1 to 4:1. This is much lower than the current ratio in our society of about 16:1 up to 25:1. It is the higher ratio that promotes inflammation.

Does meat also cause problems with protein mimicry?

This is a complex subject. The protein butyrophilin is a component of the membrane of the fat globules in cow’s milk. Closely related proteins are found in the fat globule membranes of the milk of many other species (goat, sheep, etc.).

It is one of the proteins that has been implicated in molecular mimicry in MS causation, along with BSA (bovine serum albumin). BSA is also found in the muscle of cows (beef), along with proteins similar in structure to butyrophilin. It is not clear whether butyrophilin in the milk of other species or butyrophilin-like proteins from muscle are potentially involved in MS causation, as only butyrophilin from cow’s milk has been studied in laboratory research.

However, on balance it seems wise to avoid the milk of animals other than humans. The principal reason to avoid meat in MS is because the saturated fat content of meat, although not specifically studied to date, contains proteins like BSA and butyrophilin-like proteins, which may also be an issue. We hope that helps make sense of a complex issue.

Why does Swank allow lean meat after the first year but OMS doesn't?

Because, knowing that saturated fat is a real problem for people with MS, why take any in at all if you can avoid it? After a while, most people don’t miss meat at all.

Can I eat skinless chicken on the OMS diet?

Although skinless chicken is low in saturated fat and allowed on the Swank Diet, it is not recommended on the OMS Program. The idea is to move away from eating animal products (as well as altered fats and so on) and to change your way of eating. It is important to change completely or otherwise the risk is that chicken ends up being on the table at every meal or chicken is placed on a pedestal as being a special treat. While the actual risk from an occasional piece of skinless chicken breast is low, the more frequently it is eaten the higher the risk. If you are worried about getting enough protein, there is an article by the Medical Journal of Australia that is worth reading.

Is all seafood OK to eat on the OMS Program?

Yes, people with multiple sclerosis can eat any seafood. Fish, scallops, lobster, prawns, crab, calamari, mussels, oysters, clams, crayfish – they’re all OK. Appropriate cooking methods should be followed when preparing any seafood. For more information, see ‘OMS cooking techniques‘ on this page.

Can I eat fish every day?

You can eat fish every day, however is not fully advised as fish is still an animal source of protein, and in some studies has been included in suggestions that high animal protein increases inflammation. The OMS diet is predominantly ‘plant focused’ and this includes eating plant proteins so people are encouraged to embrace this part of the program.

Should you wish to eat fish daily we would recommend limiting oily fish to three times a week (depending on quantity) and then either include shellfish or white fish on the other days. Read more about foods to eat in moderation on this page

Please note the importance of variety in the diet.

What about the mercury in fish?

The oceans are increasingly polluted, particularly with heavy metals like mercury. Mercury is concentrated in the flesh of bigger fish that eat smaller fish. So in general the higher up the food chain the fish is, the more mercury it will contain (e.g. shark, swordfish or king mackerel). In some parts of the world, eating shark is banned because of the very high levels of mercury it contains. In smaller fish like sardines, there is much less of a problem. Some people feel it is safer to get omega-3 from flaxseed oil and limit their fish consumption.

Can I take supplements in capsules made of gelatin?

Gelatin is not a problem in relation to MS. While it is an animal product, it contains no saturated fat. However, some people are either allergic to the capsules or have ethical concerns, so they may try to source non-gelatin products, which tend to be more expensive and less widely available.

Will I become anemic on this diet?

Iron is found in a variety of vegetables therefore there is sufficient iron in the OMS diet to keep most people from getting anaemic, Vitamin C can enhance iron absorption from your food, therefore in vegetarian and vegan diets, iron absorption may be optimized by including vegetables containing vitamin C during meals. it is also advised to avoid consuming tea or coffee near meals as they contain polyphenols which can inhibit iron absorption. Women with heavy periods are at greater risk of an iron deficiency. It is possible to get tested by your doctor for iron deficiency, if suspected. If you have low iron, a natural herbal iron replacement like Floradix is recommended. 

Is fasting or a 5:2 diet recommended on the OMS Program?

There is evidence from animal models of MS that fasting may be helpful. It has been shown to reduce inflammation and be neuro-protective in two animal studies.

One study in humans has been published. This looked at the effects of fasting on people with MS (PwMS) who fasted for one month (Ramadan). In this short (one month) study fasting didn’t improve fatigue but was associated with a higher quality of life.

Overall it looks promising. As there are no detailed studies in PwMS yet, restricting calories as per 5:2 guidelines seems reasonable – keeping in mind to keep to the OMS diet.

Which is better for MS - Paleo diet or OMS Program?

Dr Jonathan White explains the differences between the OMS Program and the Paleo diet in the video below.

How do I know if the diet is working?

Most people find that they feel better by changing their eating habits to OMS recommendations, but the real effect is on reducing the rate of relapses. This only becomes clear with time. It took people in Swank’s study three to five years to stabilize on the diet, that is, to get their relapse rates down to a minimum, although there was a big difference by about nine to 12 months.
