The Truth about Boosting the Immune System (& what can Live Blood Analysis tell us?)
A Very Relevant Controversy
A few months ago, the press in the UK had a field day with headlines about boosting the immune system in the light of the coronavirus pandemic.
Why?
Recently, a company that were advertising their (prescription only) vitamin injections as “immune boosting” were banned by the Advertising Standards Agency (ASA).
They actually broke the advertising laws and regulations because you can’t promote prescription-only supplements like this in the UK. They were accused of suggesting their product could be used as a strategy to prevent viral infections which exploited the anxieties people have about contracting coronavirus.
However, the message that the ASA sent out to the media and to the public was essentially that no-one is allowed to promote a product as “immune boosting”.
A flurry of articles and TV news reports ensued – talking about whether you can or can’t boost the immune system.
Many social media posts that linked peer reviewed science studies showing how deficient nutrient levels adversely affect immune function – or – that supplementing certain nutrients have been shown to improve patient outcomes, such as shortening illness duration, limiting symptoms or improving recovery post illness were removed as “fake-news”.
So, what is the truth? Can we “boost” our immune system with nutrition?
If your immune system is running perfectly smoothly and you have no nutrient deficiencies or health problems then you can’t actually “boost” it beyond its normal level of functionality.
However, there is no doubt that you can influence the health of your immune system with nutrients - through diet and supplementation - especially if things aren’t at 100%.
Our immune systems rely on being fed with a variety of vitamins and minerals that are essential to its proper functioning. These nutrients need to be consumed through the diet or through supplementation – the body simply doesn’t manufacture them itself.
In this blog post I am going to present to you
A brief summary of the immune system – how it works and which cells/organs are involved.
I will show you the actual cells of the immune system – from my clinic’s live blood analysis pictures.
The essential nutrients your immune system needs in order to function properly.
Live and Dry Blood Analysis (LDBA) can assess the client’s immune system and identify the nutrients that may be deficient. I will show you what abnormal immune cells look like and what nutrients are indicated.
The best ways you can improve your levels of these nutrients and maintain immune health.
There may be multiple factors involved as to why clients are deficient in nutrients. I discuss the main areas to focus on and which recommendations may be relevant to improve a client’s immune system.
Lets briefly break down what the immune system is, how it works and what it looks like under the microscope
There are three layers to the immune system’s defence strategy:
1 – Physical barriers and biochemical barriers
The barriers of our immune system are:
the skin - which defends our body from environmental pathogens.
the respiratory tract - which is lined with mucous membranes designed to protect us from the pathogens that we breathe in.
the acid in our stomach - which kills any bacteria we may ingest.
the lining of our digestive tract - which is a barrier to stop pathogens, such as parasites and bacteria, entering our internal circulation.
2 – Immune System Cells such as monocytes, granulocytes, and lymphocytes (B and T cells)
These are all white blood cells. They are created in the bone marrow from blood stem cells and are released into the circulation where they travel to their destination to fight infection.
3 – Antibodies or immunoglobins – products of the immune cells that actively affect invading microbes and infected cells
These are the biochemical products of the immune cells that can trigger an attack on pathogens, stimulate immune cell production and actively kill bacteria or infected cells.
The immune system is divided into different pathways:
1 – The Innate Immune System
The cells of the innate immune response are the white blood cells such as neutrophils, basophils, eosinophils and monocytes.
These white blood cells can be seen in the blood when conducting a Live Blood Analysis.
Neutrophils are the most numerous and they roam the blood, ready to engulf (phagocytose) pathogens and/or migrate out of the circulation into the tissue if called on to do their work there. They contain granules that can literally digest the pathogens they engulf.
In blood analysis you can see if there are not enough of these in the sample – indicating immune suppression. Or you may see too many of them, indicating an immune response. Both need to be addressed.
In a healthy blood sample neutrophils should comprise 60% of all the white blood cells in a live blood sample.
Eosinophils – these are most commonly found in the mucous membranes of the respiratory and digestive tract. They release chemicals as a defence against pathogens - specifically parasites - and in response to allergens in chronic allergic issues.
When you see them in the blood in numbers (they are rare wbcs) it means that there may be an active allergic response or a parasite infection.
In healthy blood sample eosinophils comprise 2 to 4 % of all white blood cells.
Basophils – also called mast cells - these are rare to see in the blood unless they have been triggered to respond.
They release heparin to prevent clotting in inflamed tissues and they release histamine as a first response to an allergen.
If you see several in a blood sample it indicates a possible inflammatory response or allergic response. For more information about how LDBA can reveal allergies see this previous blog post.
In a healthy blood sample basophils should comprise only 0.5 to 1% of all white blood cells.
2 – The Adaptive Immune System
This is a very specific targeting system that has evolved to protect us against viruses. It literally adapts to defend against specific invaders.
This system involves antigen responses - antibodies - that are produced by the T and B lymphocyte cells when they are activated by exposure to the pathogen.
T-cells – Initially, T-cells leave the bone marrow, travel via the blood to the thymus gland where they mature. They develop receptors for antigens and then circulate within the lymphoid organs until activated.
Once an antigen is picked up by the T-cell it becomes a helper T-cell and proliferates, triggering other immune cells to attack by releasing cytokines and helping B-cells produce antibodies.
T-cells can also become cytotoxic T-cells which actively seek out cells that are infected with viruses or bacteria - and kill them. They even kill cancerous cells. (see picture below of cytotoxic lymphocyte)
After infection, T-cells can become memory T-cells, which are antigen-specific and long-lived cells. These can quickly proliferate upon re-exposure to even the smallest amount of the antigen.
B-cells – These lymphocytes remain in the bone marrow to mature then they migrate to the spleen and lymphoid tissue. Here they wait – in the mucosa and linings of the colon, respiratory tract for example - to be triggered by a pathogen/antigen.
Once activated (by antigens or by T-cells) B-cells enlarge and produce specialised complex proteins called antibodies to specific antigens. (see picture below of activated lymphocytes)
Memory B-cells are long lived cells that circulate in case of re-infection and will proliferate, with the help of T-cells, to deal with a re-infection before it takes hold.
In a healthy blood sample lymphocytes comprise around 35% of all white blood cells.
Increased numbers can indicate viral infection or acute/chronic inflammatory processes, overload of toxicity or chronic infection.
Low levels can indicate lengthy chronic viral infection leading to lymphocyte exhaustion or nutrient deficiencies such as B12, B6, folic acid.
3 – The Complement System – this works with both the innate and the adaptive immune system.
As the name suggests this part of the immune system complements the actions of the others. It doesn’t include cells but it stimulates the other white blood cells into action by the production of specific proteins – chemical messengers that
Stimulate phagocytes to clear pathogens and damaged cells.
Instigate inflammation to attract more phagocytes.
Activate a membrane attack complex to kill bacterial cells.
Why is good nutrition important?
Adequate nutrition is crucial to supply the immune system with energy and the building blocks of its biochemical defence products
The immune system is complex for good reason; it is responsible for keeping us alive! You can imagine that it needs a lot of fuel and a constant supply of diverse nutrients to keep it functioning optimally.
Below is a brief summary of the most vital nutrients required along with how a possible deficiency of these nutrients can be picked up via LDBA.
Firstly – The Macronutrients – protein and lipids.
Protein -
is vital for our immune system to be able to manufacture cytokines and complement proteins.
is crucial to the mucosal barriers which are vital barrier protection.
deficiency affects the thymus gland, which matures and produces our T cells.
Protein deficiency – moderate, mild or severe - can be surprisingly common especially amongst vegetarians, vegans, dieters and those with digestive disorders. Alongside protein deficiency there are likely to be other micronutrient deficiencies as well.
LDBA can reveal protein issues – such as “protein linkage” (ineffective protein digestion, inadequate protein intake) and “lack of fibrin web” (same).
Cross-referencing other indications in the blood analysis - along with examination of diet and other symptoms, especially digestive - will help to find the root cause of any protein issues.
Essential fatty acids are another macronutrient essential for immune function. They are incorporated in the membrane phospholipids in immune cells where:
they modulate immune cell signalling and inflammatory processes.
they regulate T and B cells by taking long-chain fatty acids (arachidonic and EPA) from the membranes and transform them with enzymes to create prostaglandins and other immune cell products.
deficiency of EFAs and/or too many omega 6 fats can lead to imbalances in inflammatory responses such as pro-inflammatory issues.
Live Blood Analysis can assess the health of the cell membranes of all the blood cells – red and white – which will give an indication of lipid status.
A lack of integrity of cell membranes can be seen in cells that literally break apart, or “lyse” (see image below) in the sample. This indicates that the lipids that are incorporated in the membrane are composed of the wrong proportions and/or types of lipids.
Secondly – but just as vital – the micronutrients
The micronutrients used in the immune system are Vitamin A, C, D, E, B2, B6 and B12, folic acid, beta carotene, iron, selenium and zinc.
Zinc
Zinc is one of the most important minerals for immune function. It is not stored in the body so it needs to be constantly supplied by the diet:
A lack of zinc will:
decrease the numbers of lymphocytes
lower production of antibodies and make them less effective
disable neutrophils’ ability to move towards pathogens
increase levels of oxidative stress
Macrocytes are the biggest phagocytic cells of the immune system – they physically ingest pathogens and kill them. They cannot do this without zinc.
Pro-inflammatory cytokines are increased in zinc deficiency.
In zinc deficiency, Live Blood Analysis will show neutrophils that are non-motile, there will be low levels of lymphocytes and the Dry Blood Analysis will show high levels of oxidative stress.
Vitamin C
This is one of the most famous of the vitamins known to support the immune system.
Vitamin C is not stored in the body and so we need to have a constant supply in the diet. It is especially needed during stress and any kind of infection, because Vitamin C:
stimulates the production and function of white blood cells
stimulates motility of white blood cells
increases production of antibodies
protects white blood cells from autointoxication from the pathogen-killing chemicals they produce
regenerates vitamin E, a fat-soluble vital antioxidant that oxidises easily
is needed to help prevent the oxidative stress from damaging tissues and killing our own cells
Lack of neutrophil motility (same as above) or increased numbers of wbcs (picture) seen in Live Blood Analysis indicate a need for vitamin C.
High levels of oxidative stress as seen in the Dry Blood Analysis would also indicate a need for vitamin C.
These following micronutrients are fat soluble - they require healthy fats in order to be digested and absorbed properly - so efficient fat digestion is also key to getting enough of them into your cells.
Vitamin D
There are thousands of vitamin D receptors within the human genome and Vitamin D is thought to directly or indirectly regulate 100 to 1250 genes.
Vitamin D receptors are expressed in several types of immune system cells and vitamin D3 is now recognized to be a potent modulator of the immune system.
Vitamin D regulates antimicrobial proteins, which are critical components of the innate immune system because they directly kill pathogens, especially bacteria, and thereby enhance immunity.
These proteins also modulate immune functions through cell-signalling effects.
Vitamin D has also been shown to stimulate immune cell proliferation and cytokine production. Through these roles, vitamin D helps protect against infections caused by pathogens.
In blood analysis you can observe general immune system status through the presence, quality and levels of the white blood cells. Any indications of infection or inflammation – either in elevated levels of certain white blood cells or high levels of oxidative stress in dry blood analysis – can indicate possible vitamin D deficiency.
Vitamin A
Vitamin A is hugely important for the immune system; deficiency is surprisingly common. It is vital for protecting us on all levels against infections.
Vitamin A is crucial to the health of the immune system’s barrier protection such as the skin, mucosal cells of the eye, lining of the respiratory system and gastrointestinal tract.
Healthy neutrophils and lymphocytes require adequate vitamin A.
T and B lymphocytes need vitamin A to generate antibody responses to specific antigens.
In Live Blood Analysis we are able to make an assessment of the integrity of the gastrointestinal barrier by the appearance of “chylous” in the blood sample.
Clients fast for 5 hours before the test and so there should be no evidence of food particles in the blood – they will have all been absorbed. Chylous indicates that there may be a leak in the digestive tract – leaky gut – which can be a big indicator of Vitamin A status.
Other nutrients that need mentioning –
B12 – Cobalamin - crucial as a coenzyme that helps to build DNA synthesis. Deficiency is known to decrease the numbers of circulating lymphocytes and suppress their ability to kill infected cells.
Folate - crucial for DNA replication and normal proliferation of white blood cells.
Both B12 and Folate deficiencies can be assessed with Live Blood Analysis. Here is a link to a previous blog post for more information.
Iron – needed for proliferation of T-cells and the creation of oxidative pathogen-killing chemicals.
However, iron supplementation can “feed” pathogens and help them replicate. Which is why free iron levels are automatically stored by the body as a response to infection or inflammation.
Live Blood Analysis can show iron deficiency. The presence of high levels of microcytes (small red blood cells) and codocytes (red blood cells appear like targets) are clear indicators of low iron levels.
Selenium – several important selenium-dependent enzymes function as important antioxidants. Selenium deficiency affects antibody production, and can enhance the progression of viral infections.
Any increase in lymphocytes and other white blood cells seen in Live Blood Analysis could indicate a need for selenium. Dry Blood Analysis will show high levels of oxidative stress.
Vitamin E – powerful antioxidant, promotes cell membrane health.
B6 – Pyridoxine – part of the building blocks of the immune system proteins like cytokines and antibodies.
Eight problem areas to address in order to improve immune system function
The reason for a possible deficiency in any macro or micronutrient is likely to be multifactorial and so questions need to be asked in order to get to the root cause of a deficiency, so that the appropriate recommendations can be made.
Diet – does the diet contain the necessary nutrients?
Make sure to take a deep look at the contents of the diet. Does it contain the vitamins and minerals that the immune system requires? Are there appropriate protein levels? Which fats are being consumed and in what quantity? https://pubmed.ncbi.nlm.nih.gov/17726308/
Digestion – are there any symptoms of digestive issues, dysbiosis, inadequate stomach acid and/or stress?
All of the above factors will affect whether vital nutrients can actually be broken down, digested and absorbed. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4513829/
Exercise – too much or too little?
Over-exercising can burden the body with excess oxidative stress which uses up precious antioxidants, conversely exercise can stimulate the immune system and help it function. https://pubmed.ncbi.nlm.nih.gov/18522619/
Stress – how much emotional or/and mental stress is there?
Stress diverts energy away from digestive processes and the stress hormone actually reduces the number of lymphocytes. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4465119/
Medication – check for medication that affects the immune system.
Medicines for illnesses such as rheumatoid arthritis, crohns disease, cancer, inflammation and treatment for transplant patients all affect the immune system. They are all designed to suppress the immune system to prevent inflammation and auto-immune reactions. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4706827/
Alcohol – how much is being consumed?
Too much alcohol will suppress the immune system, whereas it has been shown that small amounts can improve it. https://www.nature.com/articles/1601486.pdf
Pollution and toxicity – what levels of exposure are there?
This is a huge problem for people living in polluted areas. Assessing toxicity sources and eliminating where possible is essential for the immune system function. https://www.semanticscholar.org/paper/Multivitamin-Supplementation-Supports-Immune-By-Air-Haryanto-Suksmasari/72892c93510d261d3e9e05770782c2ddb6cf4056
Sleep – This really matters for the immune system.
Getting the right amount of sleep will regulate the immune system as it has been shown that the wake/sleep cycle synchronises with immune activity. Release of various cellular signalling products and can regulate inflammation. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3256323/
The immune system is complex and if it is nourished with all the necessary nutrients and given the right conditions it will always act to protect us.
We can use LDBA to monitor the immune system and keep an eye on any signs of immune stress and possible deficiencies.
LDBA is not a definitive diagnostic blood test. It is used to help reach a deeper level of understanding of health at a cellular level by assessing the most valuable biological fluid, the blood.
Indications can help make correlations between clients’ symptoms, their diet and lifestyle so that any recommendations can be truly individualised.
For further nutrition information, here is a great article called Important Diet Habits To Implement For A Healthy Immune System written by Fitness Volt which gives detailed advice as to what whole foods are most effective for maintaining the health of the immune system.
