Nutrition is a vital component of health
Nutrition for People with ME/CFS
Nutrition is a vital component of health, and no less so for someone with
ME/CFS. In a 2005 survey of Sheffield M.E. Group members, nutrition was
named by the largest number of members (15%) as the therapy / treatment
which had helped them most – scoring higher than medication from the
GP/NHS (9%). What follows is a summary of the main considerations. The Effects of ME/CFS on Nutrition and Diet
• Weakness or nausea can sometimes make normal eating and
digestion so difficult that support is needed from a health professional
• People with ME/CFS have less stamina for shopping, cooking and
• Carers and family may be needed to help with shopping and food
• Meal patterns are often severely disrupted
The Patient’s Experience of ME/CFS
• Weight loss is also common - especially in children
• IBS (irritable bowel syndrome) affects 60-70% of patients at one time
or another and causes abdominal pain, bloating, wind, diarrhoea and / or constipation
• Food intolerances and sensitivities are more common in people with
• Some people also have sugar cravings when they are tired, indicating
Weight Gain – the reasons
• Eating for energy boost and craving for sweet foods or drinks
• Less energy to buy and prepare fresh foods especially fruits and
• It’s easier to grab a biscuit or make a sandwich than to make a salad
ME/CFS can lead to weight gain but is not a symptom of ME/CFS as
Weight Loss – the reasons
• Not absorbing nutrients in food properly
Excessive weight loss is always something that should be reported to
It is important to keep an eye on weight, because large changes either way will make recovery more difficult and can lead to other health risks. Ask to see a dietician if your weight has changed considerably since you have had ME/CFS.

Top tips for healthy eating with ME/CFS
Eat regularly. Small meals and snacks are preferable to occasional
huge meals. This may help to even out energy levels and reduce nausea
Avoid or severely restrict foods with a very high sugar content –
Drink plain water. Keep hydrated (do not allow yourself to become
Eat lots of fruit and vegetables (some people may need to avoid citrus
Keep off stimulants as much as you can (coffee, tea, sugar, salt,
Eat a varied, whole food diet and avoid ‘junk’ food It’s not just what you take out of your diet but also what you put in that
Make sure you do not become deficient in iron, by eating plenty of iron-
rich foods (meats, oily fish, eggs, dried fruits, fortified breakfast cereals). You also need plenty of vitamin C to help absorb the iron so eat plenty of fresh fruit and vegetables.
Eating a wide range of healthy foods is much better than taking supplements and eating unhealthily.
Dietary management of symptoms
Take your fluids apart from meal times, especially if you are nauseous.
Peppermint and also ginger may help with nausea.
Eat little and often. If you suddenly feel weak and hungry, a banana is an ideal way to deal
with the situation. Try not to resort to sweets and biscuits.
If you are overweight, take care with fats, sugars and the size of
If you are losing weight or underweight, make sure you eat foods high
in calories such as nuts and avocado, and try to see that you have regular meals and snacks.
If you are very weak you may find it difficult to chew and prefer to eat
easily swallowed food like soups and smoothies.
Official guidelines for healthy eating say that the largest components of the diet should be fruits, vegetables and grains. The foods which should form only a small part are those which are high in fat and those which are high in sugar (or both!) However the diet must include the Omega 3 essential fatty acids (more on this later).
Irritable bowel symptoms (IBS)
Bloating after food Constipation/diarrhoea or both Abdominal pain Flatulence
Possible solutions for IBS
• Dietary and nutritional assessment by a health professional
• Adjusting the type and amount of fibre in the diet. Oats and wheat
have different types of fibre and you may be able to tolerate whole oats better than wholegrain bread. If you can only digest boiled vegetables, keep the water for soups or just drink it separately for its rich mineral content (it sometimes has more than the remaining vegetables!)
• A careful exclusion diet, with proper advice, to test whether there are
any food intolerances. Sometimes these can exist for a while and then disappear.
• Many people find probiotics and / or digestive enzymes helpful
Sheffield M.E. Group has an Information Sheet on Irritable Bowel Syndrome and also one on the wheat-free diet. Please send a large stamped self-addressed envelope to receive copies.
Food intolerances / sensitivities
As well as abdominal symptoms, these can cause headaches, lethargy and a
range of uncomfortable feelings.
The most common suspects are milk, wheat, soya, yeast, caffeine,
alcohol and other stimulants – but this is not a complete list!
Do not follow an exclusion diet without professional advice if it means
that you are missing any of the staples of your diet.
It is possible to lose a particular sensitivity after avoiding the item for several months. Allergies are different from sensitivities in that they more fully involve the immune system. This area is under-researched and many GPs are unwilling to carry out allergy tests unless symptoms are very severe. (Dr Hayes Allen is an exception – see below.)
Issues to consider
Is your diet nutritionally adequate and varied? It should include a
variety of fresh, whole foods, avoiding sugar and refined carbohydrates as much as possible.
Anyone who is losing weight alarmingly must seek professional advice. Are supplements needed? Vitamin D is recommended if you are
unable to get out into daylight. Also, supplementing essential fatty acids is helpful if your diet does not include oily fish or uncooked Omega 3 vegetable oils.
If you feel a particular diet or supplement is not helping, then you
should discontinue it. However metabolic changes take up to three months and more, so give it time.
The financial cost of the diet is a consideration. You may wish to eat
organic food all of the time, but if this is not possible you could choose to eat just organic bread and / or root vegetables as these absorb particularly high amounts of chemicals from the soil. Fresh fruits and vegetables are cheaper than convenience foods. Preparation time is also a ‘cost’, for people with ME/CFS. If the work involved in cooking and shopping makes you more tired there could be an overall negative impact.
It is a good idea to prepare extra dishes on a ‘good’ day and freeze
It may be better to have a ready-meal occasionally than to go without
Remember that the enjoyment of food is part of its benefit!
Supplements – to take or not to take?
Reports from large numbers of people with ME/CFS say that a supplement of essential fatty acid
has been beneficial to them. There are new reports that Vitamin D
is also helping. If you cannot manage 10 minutes of gentle
sunshine on your face and forearms most days, for two thirds of the year, then
it is recommended to take a supplement, at no more than the recommended
dose. Multi mineral / vitamin supplements are safe to take at the
recommended dose. Buy a reputable brand, and always read the label.
Professor Basant Puri, an eminent scientist in the field of ME/CFS research,
emphasises that it is much more important to eat fresh, whole foods (not
refined and not packaged) than it is to take supplements.
Who are the experts?
Within the NHS you may be referred to a dietician who can help you adjust
your eating habits to help with your symptoms. Dieticians are state
registered, and their services are free within the NHS. Outside the NHS you
may see a nutritionist or nutritional therapist, who can recommend strategies
and supplements that are not ‘allowed’ in the NHS. If you choose to do this,
you should ensure that he or she is a registered practitioner member of a
professional organisation – the most reputable ones are the British
Association for Applied Nutrition and Nutritional Therapy (BANT), the Nutrition
Society, and the Nutrition Therapy Council. You will be charged for
consultations and for the supplements.
What do the main M.E. Charities say about nutrition?
The M.E. Association
The MEA acknowledges evidence of deficiencies involving magnesium, folic
acid and several B vitamins, but because of lack of evidence from clinical
trials, the Association’s advice to doctors is that “The only clear indication for
supplements is in the case of women with ME/CFS who are contemplating
pregnancy.” They advise “a well-balanced diet that includes complex
carbohydrates (to help stabilise blood sugar levels) and which avoids caffeine.
A good fluid intake should also be encouraged.”
Action for M.E.
AfME suggests experimenting with the diet with the guidance of a specialist, if
digestive or gut problems are experienced, to find out if there is food
intolerance. It also advises an adequate intake of fluids and states “If you are
concerned about the quality of your diet you may want to consider taking a
simple multivitamin on a regular basis.”
What do specialist doctors advocate?
Partly because of the complexity of the illness and the differing needs of sub-
groups, only a minority of specialists have formulated nutritional protocols for
Dr Sarah Myhill
Vitamin B12 injections and Magnesium supplementation are foundations of Dr
Myhill’s treatment (see www.drmyhill.co.uk). Her recovery programme is
based on reducing stress including toxic stress, and on good nutrition. In her
programme, carbohydrates should be cut down during the daytime because
they cause drowsiness. Protein and good fats should be the mainstay of
daytime meals with bread, potatoes etc eaten only at the last meal. She
recommends an initial four weeks on a diet which excludes common allergens
and unhealthy foods, i.e. wheat, rye, corn, dairy produce, tea, coffee, sugar,
yeast, all chemical additives, plastic wrappings, and over-ripe or mouldy
foods. Carbohydrates are obtained from rice, millet, buckwheat, sago,
quinoa, all the pulses, potatoes etc. This is NOT a calorie-cutting diet. After 4
weeks foods can be returned individually and monitored to test for
Dr Myhill is currently developing a nutritional protocol for addressing a model
of ME/CFS as heart weakness secondary to mitochondrial malfunction (as
described in work carried out by Dr Arnold Peckerman for the U.S. National
Institutes of Health). Her new protocol provides specific nutrients aimed at
restoring mitochondrial function but full results over a long period are not yet
published at the time of writing (July 2008).
Professor Basant Puri
Essential Fatty Acids (EFAs) are one of the most studied aspects of nutrition
in ME/CFS. Professor Puri’s protocol is set out in his 2005 book Chronic
Fatigue Syndrome: a natural way to treat M.E. This is based on previous
research into fatty acids and ME/CFS and also on his own research as
consultant at Hammersmith Hospital, London. Based on the theory that viral
infection destroys enzymes involved in fatty acid synthesis, his programme
involves supplementing with a specific EFA supplement called VegEPA which
contains only virgin evening primrose oil, pure EPA and NO DHA, for reasons
he explains in the book (summary available from Sheffield M.E. Group).
In addition he advocates a nutrition approach aimed at boosting the vital
enzymes involved with EFA metabolism. This means a diet based around
lean beef and lamb (organic if possible), oily fish, vegetables (such as vitamin
B-rich leafy greens), fruit, (especially vitamin C-packed kiwi fruit and
strawberries), peas and beans, pulses and lentils, whole grains, brown rice,
seeds, (particularly pumpkin and flax), nuts ( such as almonds and brazil)
organic whole milk and yeast extract. He recommends supplements if
deficiency is suspected.
Dr M Hayes-Allen
Dr M Hayes-Allen is a GP specialising in ME/CFS who has a private practice
in Sheffield. He looks at thyroid function and prescribes immune system and
allergy tests, mineral status tests done on the patient’s hair, and tests for gut
infections and ‘leaky gut’. He recommends a diet rich in B vitamins, EFAs and
minerals, especially magnesium, zinc and selenium – including supplements,
though secondary to food sources. He sometimes recommends Magnesium
What then are the main concerns for people with ME/CFS?
Essential Fatty Acids
Though evidently not all practitioners agree on the best nutrition for people
with ME/CFS, they do agree that essential fatty acids are very important.
Some of the most extensive research has been carried out by Professor
Basant Puri at Hammersmith Hospital, as mentioned above.
Deficiencies of essential fatty acids in the modern western diet are of
particular interest to people with M.E. because these nutrients are involved in
brain function and in immune function.
What are essential fatty acids (EFAs)?
EFAs are the only fats that we actually need to eatThe EFAs are
‘polyunsaturated’ fats, as opposed to the ‘mono-unsaturated’ and the
‘saturated’ fats, which are the other main groups of dietary fat.
EFAs are needed by each body organ to produce prostoglandins, which act
like hormones and regulate the continual functioning of every part of the body.
They also become part of the membrane fabric of every body cell, enabling
the transfer into the cells of vital oxygen and nutrients. They keep the
immune system healthy, and reduce inflammatory conditions such as in
arthritis and allergies. And most importantly, the brain is 60% fat, with EFAs
forming the larger part.
Omega 3 Fatty Acids – Alpha-Linolenic Acid
Omega 3s are found in oily fish (like herring, mackerel, sardines, pilchards) but also in flaxseeds, pumpkin seeds, and other foods, including soya bean, walnut, hemp oil and rapeseed oils, green leafy vegetables, grains, and sea vegetables. Some nutritionists advise taking oily fish rather than relying solely on vegetable sources of essential fatty acids.
Sheffield M.E. Group has an information sheet about essential fatty acids, and also a report on a talk given to us by Professor Puri in 2007. Please send a large stamped self-addressed envelope to receive copies.
This is sometimes mentioned in the contect of ME/CFS. The glycaemic index
is the rate at which food converts to glucose (energy) in the body. All
carbohydrate foods are ultimately converted to energy in the form of glucose.
If sufficient calories are not taken in the form of carbohydrates, even fats and
proteins are converted to glucose because it is so crucial for the operation of
each cell in the body. If the glucose is not used for immediate energy
requirements, it is converted to fat and stored in the tissues. Foods with a
high GI rating convert quickly to glucose, and those with low GI take longer.
The aim of the GI principle is for the food to deliver energy gradually
throughout the day, rather than in sporadic bursts. This will prevent energy
slumps and keep the blood sugar levels at a healthy balance. Whole grain
foods take longer to digest, thus releasing their energy more gradually.
Refined carbohydrates such as sugar and white bread are high GI foods and
deliver glucose to the cells rapidly. Because high blood sugar levels are
dangerous, the body produces an ‘insulin rush’ to deal with the situation and
so there may follow a rapid lowering of the blood sugar – hypoglycaemia. If
this cycle continues, weight gain and even type 2 diabetes can result.
The GI diet is implemented by concentrating on foods low on the index.
However, the situation is complicated when the accompanying foods are
taken into account. For instance, a jacket potato – which is evidently a
healthy, wholefood source of carbohydrate and other nutrients – has a very
high glycaemic index because its carbohydrate is very easily converted to
glucose. However, because the potato would usually be eaten with butter or
olive oil, and ideally accompanied by salad vegetables, the overall glycaemic
index of the meal would be lowered. When fat accompanies the
carbohydrate, the GI is lowered – hence, a Mars bar has a much lower index
(68) than a jacket potato (85)!
These complications mean that implementing a GI diet needs careful thought,
which may not always be easy for people with ME/CFS. However the
principle is valid. It is unhealthy to eat high sugar foods which in the long run
can cause weight gain and hypoglycaemia. Whole foods release energy
more slowly and are more healthy.
Candida – a brief overview
Candida or candidiasis (Candida overgrowth in the gut) is ignored by many
doctors though it is frequently linked with ME/CFS. The medical profession
sometimes denies its existence, except in very limited cases, making it difficult
to get a medical diagnosis even when an overgrowth has been confirmed by a
laboratory test. Moderate amounts of the yeast Candida live in everyone
without causing harm, but naturopaths say that when the surrounding bacteria
which normally check their spread are destroyed (for instance by antibiotics)
Candida can change into its fungal form and spread through the intestinal wall
into the bloodstream. Incompletely digested products and compounds
resulting from breakdown of the Candida can then also pass into the
bloodstream, where they cause a multitude of symptoms in addition to
problems already in the gut (indigestion, bloating and pain). This crossing of
the gut wall is what is known as ‘leaky gut’, and its symptoms are many of the M.E. symptoms. However ‘leaky gut’ is not considered by most doctors.
Treatment - Many naturopaths, nutritionists, homeopaths and medical herbalists will treat Candida using a protocol aimed at removing the sugars that feed the overgrowth, providing antifungal agents, eliminating food triggers and healing the leaky gut. Most importantly, the diet recommended would eliminate all sugars, all yeast containing foods and all fermented foods (bread, vinegar, mushrooms) and also tea, coffee and alcohol.
Dr Anne Macintyre describes Candida overgrowth as causing dysbiosis in the
gut (rather than leaky gut as such) and she sets out the anti-candida diet in
her book M.E. a Practical Guide.
This is one of the widely used ‘standard
texts’ for self-help with ME/CFS. The anti-Candida diet has not been shown
to be successful in controlled tests, but many individuals with ME/CFS have
found it has improved their health.
A study published in the Journal of Human Nutrition and Dietetics in March
2008 showed that the symptoms of ME/CFS are not improved by extreme low
sugar, low yeast diets. However
this study has been criticised for the criteria
used to select its subjects, for the fact that the subjects were not tested for
signs of gut abnormalities to start with, and for the relatively high drop-out rate
during the research. Nevertheless it has played a big part in discrediting the
usefulness of addressing the possibility of candida overgrowth for people with
New thinking on Candida?
New thinking amongst some naturopaths points to a different cause and
treatment of Candida. In this view, excess fat is the culprit, not sugar as such.
When fat levels in the blood rise, so does blood sugar, because excess fat
inhibits insulin from its function of taking sugar out of the blood. The excess
fat lines the blood vessel walls and the contents of the blood vessel, including
the insulin receptor sites, and the sugar and insulin themselves, thus slowing
the normal process of glucose absorption. In this naturopathic view, Candida
is constantly present in the blood, with the function of blooming when there is
an excess of sugar, so that the blood sugar is brought down to a non-
threatening level. When the fat and sugar metabolism is as it should be, the
Candida quickly dies off to its non-symptom-causing level.
So, according to this view, when fat levels stay high because of a poor diet,
sugar remains in the bloodstream and feeds the Candida rather than
delivering energy. Therefore the way out of the situation is not to eat less
sugar, but to eat less fat. When the fat content of the bloodstream drops,
sugar starts to be processed and distributed again, and Candida dies out
because there is no longer excess sugar available. A low fat diet is in any
case a healthy diet provided that essential fatty acids are included.
Some other nutrients and supplements which have been associated with
This is a herb which supports the immune system when used correctly. It has
helped some people with M.E. for a short time only and should not in any
case be taken over extended periods.
This is a nutrient which the body makes for itself naturally, to help the cells
produce energy. It is used by many nutritionists and by Dr Sarah Myhill as
part of an overall package of supplementation.
This is another coenzyme, which the body makes from vitamin B3. As a
supplement it seemed to help many people when it was first used for ME/CFS
but did not prove to have permanent benefits for the majority.
This is an amino acid (protein) and where there is a deficiency it has been
shown to help some people with ME/CFS. It is likely to be most helpful when
used in conjunction with other supplementation. Food sources include red
meat, diary products, avocado, and tempeh (made from fermented beans,
available in wholefood shops).
Every cell in the body uses magnesium for energy and protein metabolism.
Many people with M.E. are found to be deficient in this mineral, and in these
cases supplementation and even magnesium injections have been found to
be helpful. Food sources include nuts, seeds, pulses and green vegetables.
This is a hormone secreted by the adrenal glands and if it is deficient its
supplementation may help with memory, stress, anxiety and sleep.
These help break down food and can be useful in ME/CFS. Fresh uncooked
foods (salads and fruit) also support the body’s enzyme activity
This is highly valued in Chinese medicine and an ingredient in most of their
herbal formulae. It helps combat fatigue.
This is a protein which supports certain neurotransmitters which are known to
cause low energy when deficient. It is found in many protein-containing foods
including meat, fish, milk, wheat and oats.
This is a very specialised part of the carbon/sugar chemical chain which acts
within the cells to help produce energy. The body makes it own, and it is also
available as a supplement.
It should be evident from the above that nutrients are wide ranging and inter-
related. As a science, nutrition is really in its infancy and new findings are
constantly being published.
The most important things for someone with ME/CFS to bear in mind are that your food should be:
• In the most natural state possible (wholefood)
• Including a good amount of uncooked fruits and salads
