It is known that strenuous exercise and sport reduces innate mucosal immunity, which is the first line of defense against catching viruses and bacteria that play a role in most respiratory diseases.
A small but interesting study of 41 male marathon runners who completed the 42,195 km Barcelona Marathon in 2016 showed that those who did not receive the test supplement (made of polysaccharides from arabinogalactants, aloe vera, gums and algae) had significantly lower salivary sIgA after the race. Lower levels of sIgA indicate decreased mucosal immunity, which is the first and most important defense mechanism to stop pathogens, such as viruses, to enter our body through the mucous membranes of the airways.
Polysaccharides are known to play a role in immune activation and inflammatory processes. Many are better known as prebiotics. Currently, there are three major types of prebiotics that are well documented: inulin, oligosaccharides and arabinogalactans. Other well known polysaccharides are beta-glucans from mushrooms, seaweeds or oats.
Food for friendly bacteria
These types of polysaccharides are not digested by human enzymes of digestive tract but they have an important role to play as a food source for our microbiota.
Many studies suggest that the combination of different types of these indigestible polysaccharides provides nutritional benefits by prolonging microbial fermentation in the intestines. This is known to increase uptake of micronutrients such as vitamins and minerals. The presence of prebiotic polysaccharides keeps the intestinal mucous layer healthy, which promotes the process of absorption of nutrients. If the mucous layer becomes unhealthy and inflamed, the absorption of nutrients is compromised (such as happens in coeliac disease).
Training immune cells
It is easy to understand why prebiotic polysaccharides are useful for the intestinal mucosa. However, it is somehow more difficult to imagine their mechanism of action on other mucous membranes, such as in the respiratory tract. Here comes the second action of polysaccharides. When parts of their molecules cross the intestinal wall, they get scrutinised by the immune cells in the same way as any large and undigested structures would be. Immunity becomes vigilant, but not over-reactive. It becomes activated sufficiently to function properly and ready for a real threat.
The runners took the supplement at dose of 8 g/day for 15 days before the marathon. The supplement was made of arabinolactans, Aloe Vera, rice starch, ghatti gum, gum Tragacanth, Glucosamine HCl and Wakame algae extract. These 15 days were probably enough to ensure more optimal and less-inflammatory state in the intestinal mucosa, which would help better nutrients absorption. However, it is believed that the main effect is happening on the other side of the intestinal layer, called lamina propria, where most of the body's immune cells are trained and developed. This training of immunity would cause a systemic effect (that is, in the rest of the body), thereby promoting a healthier condition of all mucous layers, not only the intestinal ones.
Arabinogalactans are class of long, densely branched polysaccharides belonging to hemicelluloses. In most plants, arabinogalactans occur bonded to protein, either as proteoglycans or as glycoproteins. Many edible and inedible plants are rich sources of arabinogalactans including leeks, radishes, carrots, tomatoes, coconut etc. However the structure in the Western larch tree is slightly different and water-soluble, which makes it more suitable to make concentrated prebiotic supplement.
Aloe Vera, gums and algae extracts (containing fucose, fucoidan, mannose, mannitol...) in the tested supplement would enhance the fermentation in the intestines and therefore help to create stronger and faster immune effect.
Are supplemental prebiotics polysaccharides suitable for me?
How much fruit and vegetables do I need to consume to have the same effect?
What about SIBO??

Human microbiota consist of many bacteria, viruses, fungi and even parasites which live with us peacefully, keeping us healthy and training our immune system to be active and balanced. Only balanced immunity can face new or opportunistic pathogen with enough power but without creating serious side effects.

Some of you experienced results almost immediately, and it was easier to keep the diet if health improvements were evident. Many needed to combine it with other type of "diets", eliminating both food and non-food personal „kryptonites“. Maybe some had no visible improvement. As a consequence, it is harder to believe that food is connected to a specific health problem. If the latter is the case, please remember that IgG allergy is only one piece of puzzle. It is only one part of complex and highly individual gut-healing Protocol 4R (or 5R).
In all cases, whether improvement has been noticed or not, keeping this test-based elimination diet has had a positive influence on health. Giving a long-needed break to overloaded immunity - by lowering overall inflammation mechanisms - it created more space for healing. Rather than being occupied by daily fights with incoming allergens, the immune system could use the spare energy for regeneration and repair. For many people, this could mean lowering general pain and discomfort.
The recommended time for an elimination diet is 3-4 months but what’s going to happen next - coming off the diet - is no less important.
Many make the crucial mistake of jumping off the diet suddenly and „treating“ themselves to a good portion of „forbidden“ food. Be it a whole slice of (wheat) bread, cake or a pot of ice cream. If this is how you ended the diet, it is possible it was, unfortunately, a waste of time. By the sudden introduction of your „kryptonite“ food, and before making sure the gut is healed and sealed, you’re risking not only a bad reaction to given food but also continuing inflammation and/or leaky gut syndrome.
Please do not waste your time and £££ testing for IgG allergy if you’re not going to do it right. Bad rep to these diets and lab tests often come from people who treat this diet as a simple black&white list. Always try to find practitioners who can take you through the complete functional medicine „Protocol 4R“. This protocol may take several months or even years, depending on your situation and the level of ill health. Be patient. Quick fixes by a straightforward elimination diet may work fine for those reasonably healthy, but symptoms may creep back slowly.
Coming off the diet
1. Do not stop the diet abruptly. Do not eat a whole portion of previously eliminated food. Go slowly.
2. Make sure the gut is healed and sealed, ready to take on the allergen. You can test this directly by a special test for gut permeability or indirectly - by repeating the FoodPrint (or another IgG test), to show the level of improvement.
3. Forget the first three foods on the list, which scored the highest, at least for another couple of months. This is often very difficult for many people as it involves wheat and/or gluten, soy, egg and dairy. Unfortunately, 90% of the cheapest and most accessible foods contain one of these four ingredients. Read the labels.
4. Start with the least reactive foods on the list (orange colour and lowest in red). Introduce them in small amounts, no more than 1-2x per week. Do it as if you were introducing new foods to a baby - no more than a small bite or one leveled teaspoon.
5. Rotate. Do not eat any of the listed food daily. For example, if you had oats (porridge, oatcakes etc.) on Monday and Tuesday, avoid them for 3-4 days.
Considering our genetics (how our ancestors lived), eating simple meals, ideally up to 10 ingredients daily and rotating them over time is what a varied diet should look like. Our ancestors did not have a massive variety over a day or week but changed diets with seasons. Possibly the only exception were days of feasts, only a few times per year.
Introducing the most problematic foods
Think about why they are the worst offenders and if, in your case, it is worth eating them at all. Double check the IgG test, coeliac panel Cyrex Array3 or true IgE allergy.
Moreover, gluten is a thyrotoxin and tissue mimicker, causing problems even if none of these tests show any positives. Too much soy interferes with thyroid function, a well-known goitrogen, and most of it is GMO.
Gluten and grains - make a homemade bone broth soup into which you add some grains as pasta. Do not eat pasta at first when having this soup. Small amounts of gluten protein will be released into the liquid. Bone broth helps to heal your intestinal lining. The effect of re-introduced gluten will hopefully be dampened down. Another way is to start buying porridge oats that are not gluten-free certified and, are usually contaminated with few grains of wheat or barley. Choose organic if you can.
Dairy – a good way to start is with butter (goat or cow) and fermented dairy products. Try organic homemade sour whey, quark (soft cheese) or a teaspoon of coconut-dairy culture mixed yogurt. Hard cheeses only as few strands of grated cheese at first, no more! Probably the best way of introducing dairy protein is in the form of colostrum supplement, which can seal your gut very quickly. It's the original function of colostrum to do just that in newborns!
Egg – split the white and yolk, depending on your needs. If you tested for both, introduce both but in tiny amounts. Start introducing an egg that is not highly denatured (such as happens after baking). Try soft-boiled or a scrambled egg made for another family member. Have only 1-2 teaspoons at first and only once per week.
How to prevent new food sensitivities
Eat a varied diet (see above what I mean by it) by rotating all foods weekly or seasonally, specifically those previously tested positive.
Do not eat the same foods and food ingredients every day, all day.
The biggest concern is the presence of highly reactive and pro-inflammatory gluten, wheat & other grains, denatured powdered egg, dairy and soy. Most of these can be hidden, including „health foods“. This includes vegan or vegetarian meat imitations, some made of pure gluten, some of pure soy, or Fusarium mold. Frightful! Cheap processed meat can also be filled with wheat and soy flour, as well as ready-made meals, cakes, bars, non-dairy replacements and sauces. Another bad example is snacking on a whole bag of nuts at once.
Remember that your immune-based sensitivity to food (by forming IgG antibodies) is only one type of body reaction to food.
If you test IgG positive, then correctly proceed through the elimination diet, and if nothing improves, you have to dig deeper. There can be several other reasons:
1.True allergy to foods - shows as an increase of IgE (not IgG) antibodies.
2.Environmental reactions. Both IgE and IgG can develop towards chemicals hidden in food, every-day cosmetics, cleaning products or even environmental dust (biotoxins - pollen, mites, molds and their mycotoxins – this is sometimes called the sick building syndrome).
3.Enzymatic insufficiency-based intolerance to foods (such as lactose or histamine). This deficit of enzymes can be natural, such as losing tolerance to milk sugar lactose in adulthood. Another example is dysbiosis-induced fructose malabsorption (or wider FODMAP malabsorption).
4.Reactions to lectins such as WGA, solanin, salicylates or other plant-protecting phytochemicals.
5.Cross-reactions. Both IgE and IgG-tested foods/items can have several other cross-reacting pals. For example, if you don’t eat buckwheat but tested positive for all other grains, you are likely to react to buckwheat, too (even if test does not show it). Cross-reactions must be taken more seriously when dealing with autoimmunity, and this stricter version of an elimination diet is called AIP = autoimmune protocol.

When people get diagnosed with CFS, they are most likely told it is a psychosomatic illness. The meaning of "psychosomatic", found in various dictionaries online, being:
...caused or aggravated by a mental factor such as internal conflict or stress...
Medical dictionary meaning of this word is slightly more complicated and we learn, that even asthma, migraine, and peptic ulcer is "psychosomatic"! Therefore more or less related to our emotions and stress, as are most chronic illnesses... Shouldn't we all be sent to a psychotherapist for a correct diagnosis?!
After a long and somehow uneasy decade of self-managing this condition, I have looked at the NHS website with a hope, that there would be something new on offer in terms of testing, treatment, guidance or a specific support. I haven't found anything new, but their website pointed to ME Association with the article I copy below in full.
You can also check my small "collection" of information on this subject here and the latest outcomes from the same group of scientist are becoming more and more specific in terms of biomarkers (Nagy-Szakal et al. 2018):
Among the top plasma biomarkers differentiating ME/CFS patients from controls were decreased levels of betaine, complex lipids (lysophosphatidylcholine [LPC], phosphatidylcholine [PC]) and sphingomyelin (SM), and increased levels of triglycerides (TG), α-N-phenylacetyl-glutamine, ε-caprolactam and urobilin (Table S2). Set enrichment analysis of the results of logistic regression models revealed that ME/CFS subjects had reduced levels of PCs and dysregulation of the choline-carnitine pathway (Table 2).
I do hope that the mystery of CFS is on a good way to be resolved by mainstream medical science. In the meantime, functional medicine and nutrition has a lot to offer to support overall health if you want to be pro-active and not just wait for "magical pill".

W. Ian Lipkin, Director of the Center for Infection and Immunity and the Center for Solutions for ME/CFS at Columbia University, has written the following letter several days before the Fourth Annual Conference on Psychosomatics at Columbia University this weekend. The original letter can be found at this link.
Dear Colleagues and Friends,
In 2017, the CII was selected to host one of three NIH centers funded for collaborative research into the biology of this disease. The Center for Solutions for ME/CFS (CfS for ME/CFS) includes representatives from #MEAction and Solve ME/CFS as well as clinical and basic scientists drawn from leading academic institutions and clinical sites across the United States.
Our studies of blood, cerebrospinal fluid, saliva and feces, using state-of-the-art methods that include microbial gene sequencing, metabolomics, proteomics, and immunological profiling, confirm that patients with ME/CFS have biological abnormalities that cannot be characterized as psychosomatic.We are committed to actively investigating the causes of immunological and metabolic abnormalities in ME/CFS. Our hope is that this work will enable insights that lead to treatments.
Committees convened by the National Academies of Sciences, the National Institutes of Health, and the Centers for Disease Control and Prevention have also concluded that ME/CFS is not a psychosomatic disorder.
