Smorgasbord Health Column – The Immune System – Your role in protecting the body from a virus

I am continuing with the re-run of the Immune System series as it is a message that I believe is well worth repeating.

Most diseases today that are not genetically passed on to us are lifestyle induced. This means that as a rule we are masters of our own health outcomes and need to own the responsibility. I know that most of you that are reading this do just that and that I am only underlining the steps you have already taken. If you do know someone you feel does not share that healthy outlook on life, perhaps you might pass this on. I needed that nudge 25 years ago and it certainly set me on a different path.

I spent most of the first 40 years of my life in ignorance when it came to my body. I had studied biology at school and apart from a scary film on childbirth (meant to be the ultimate contraceptive), I knew more about the insides of a frog.

As a family we ate well… But it was not related to our health in any way. Certainly as I stuffed food in one end I gave little thought as to what happened to it on its journey to the other end. I was more concerned that my sugar craving was satisfied and I was then a happy bunny.

It took the short and very sharp shock of finding out that my ignorance had led me to a dark place physically with lifestyle related diseases associated with a woman in her 70s and 80s. Completely self-inflicted and I could not blame my genes, my family nor could I adopt a ‘poor me’ approach to blame.

It is not as though I was stupid. I was a senior manager in a large company with a stressful but very fulfilling job. But I had no control over my eating. I have always devoured books as well as food and now it was time to go into overdrive and learn how to take back control of my failing body.

As I studied medical textbooks and online research by leading nutritionists; a light went on. I had been dismissive for most of my life about my body and the functions it performed, mainly without my assistance 24 hours a day 7 days a week. My only contribution was to give it the nutritional and physical support to do its job; and I had been failing miserably.

Supplements

We live in a world of quick fixes. For example, in supermarkets, pharmacies, in the press you find anti-oxidants advertised for your immune system –when do you think our 100,000 plus year old body decided that it was better to get its nutrients from a capsule or tablet?

And considering that it does take 10,000 to 12,000 years for a DNA mutation that might make a small change in the way the body processes nutrients for its needs, I think it is clear that we still need to ingest the good old fashioned food to give it a fighting chance.

I do advocate the occasional use of supplements, when needed, to additionally support the body. You must do your research however, and it is better to buy a reputable brand that gives you all the relevant information and has advice on hand if you have questions.  Many cheaper brands may be fine, but often the pills will just pass through you without your body receiving any benefits at all.

If you add up how much you are spending on keeping your immune system healthy with supplements, then I think you will find that you could be enjoying a fantastic diet, rich with more than enough fresh foods to do the job better.

The reason for somewhat long winded introduction, is that over the many years that I have worked with clients and written about food and nutrition, I have learned that if someone understands how their body works, and how truly amazing it is they will put everything into losing weight, improving their immune system function, working to improve conditions such as diabetes etc.

So, fasten your seat belt! Here we go with part three of the immune system -how it reacts to an infection like a cold, and some more foods to help support your defences in the massive task of keeping you alive.

If toxins and germs get past our first barriers such as the skin etc then the body needs to muster its troops very quickly to contain the situation. Apart from our blood stream we have a network throughout our bodies which is called the lymphatic system. It is a little like a railway network with stations along the route, which are called glands. You will often hear people say that the glands are up for example when they have an infection.

The most noticeable are usually the lymph nodes in your neck, under your armpits and in your groin. The lymph fluid, which is called plasma, travels along the network, reaches one of the stations and drops off any harmful bacteria in the node. The lymph system contains a number of cells that sound like something out of James Bond movies. B-cells, Killer T-cells – Helper T –Cells macrophages and lymphocytes and these and all other blood cells are produced in our bone marrow. (Which is why bone marrow transplants from healthy marrow can save the life of another person)

All these cells have specific roles to play (for example the macrophages swallow bacteria to kill it) and to give you an idea of the immune system at work this how the common cold virus is dealt with in the body.

A common cold is an illness caused by a virus infection located in the nose but which can also affect the sinuses, ears and the bronchial tubes. The symptoms include sneezing and sore throat for the first 24 to 36 hours followed by blocked nose, scratchy throat with possibly headaches, feverishness, chilliness and coughs.

It is not actually the virus that causes all the unpleasant symptoms of a cold. The virus attaches itself to a small proportion of the cells in the lining of the nose. It is in fact the body’s response to the invasion that causes all the symptoms. The immune system is activated and also some of the nervous system reflexes. A number of white cells from our defence system, including killer cells, are released into the blood stream such as histamine, interleukins and prostaglandins. When activated these cells cause a dilation and leakage of blood vessels and mucus gland secretion. They also activate sneezing and cough reflexes to expel infection from the nose and the lungs.

It is these reactions caused by our own killer cells that are treated by the over the counter medications, not the actual virus itself. By suppressing our bodies own reactions to the virus we can drive it further into the system causing more harmful infections, particularly if we have already got a weakened immune system.

After the killer cells have dealt with the initial infection, antibodies are released that help prevent re-infection by the same virus. This is why as we get older we should suffer from less cold infections.

Avoiding colds in the first place.

There are two main ways to protect yourself from catching a cold virus. One is to minimise the risk of infection through contact with people and objects that have been infected, and the other is to build your immune system to enable you to deal with viruses if they do attach themselves to you. It is almost impossible to avoid contact with people or with objects they have touched with their hands. Some of those people are going to have a cold or influenza and short of doing a ‘Howard Hughes’ and retreating into a sealed room you will have to make do with the main simple but effective precautions.

P.S – Shoppers.. Worth investing in some natural antiseptic wipes with peppermint, citronella, lemongrass,orange, patchouli oils etc and wiping down the handles of supermarket trollies. All these in laboratory tests were effective against 22 bacterial strains and fungi. Think about it!  And wash your hands before you touch any of the raw food you bring home with you.

http://www.ncbi.nlm.nih.gov/pubmed/8893526

Wash your hands frequently with ordinary soap and hot water to avoid passing the virus into your nose. For the elderly avoid shaking hands and kissing family and friends. If you have a baby ask kindly meaning admirers to not touch or kiss it.

Also you should exercise regularly in the fresh air and avoid over heated, unventilated living spaces. If your nasal passages dry out they are more likely to become infected and this applies to those of us who live in air-conditioned and centrally heated environments most of the year.

Some natural anti-virals.

Vitamin C and Zinc are great nutrients in the fight against the cold. Vitamin C or Ascorbic Acid is water soluble and cannot be stored in the body and is the most powerful water-soluble anti-oxidant. Not only does it protect us from free-radical damage but it works to neutralise potentially harmful reactions in the water-based parts of our body such as in the bloodstream and in the fluid around each cell. In the immune system it works to increase the production of our white blood cells that make up our defences. It can also modulate the reaction to a cold for example by lowering the levels of histamine which is causing the runny nose.

The best source for Vitamin C is all fresh, raw fruit and vegetables – and the highest concentrations are in black currants, broccoli, Brussel sprouts, cauliflower, cherries, grapefruits etc… A word of warning – if you buy already prepared and cut vegetables they will have lost varying percentages of their Vitamin C depending on how many days old they are. You may only be obtaining a third of the initial amount of the vitamin by day four or five. Frozen food on the other hand that is picked and frozen is a great option if you can only shop once a week.

If you are starting a cold; drink hot water with the juice of half a lemon and a teaspoon of honey. One of the herbs that I use during the winter months is Echinacea  and I will take from November through to January to help boost my immune system.  If you take as a cold begins, rather than supress the immune system it will support it. However, the old saying that a cold will be gone in ‘a week or seven days’ is usually accurate. The very young and the elderly are vulnerable to more serious respiratory complications and extra care should be taken.

pumpkin seedsZinc is often referred to as the healing mineral -there is evidence to suggest wounds heal faster and certainly it supports a healthy immune system. So foods to include are: – Seafood, pumpkinseeds, sesame seeds, wheatgerm, egg yolks and tofu. Sprinkle the seeds over your porridge in the morning – or make your own home-made muesli – enjoy an egg a day for breakfast.

A little bit about me nutritionally.

A little about me from a nutritional perspective. Although I write a lot of fiction, I actually wrote my first two books on health, the first one, Size Matters, a weight loss programme 20 years ago. I qualified as a nutritional therapist and practiced in Ireland and the UK as well as being a consultant for radio. My first centre was in Ireland, the Cronin Diet Advisory Centre and my second book, Just Food for Health was written as my client’s workbook. Here are my health books including a men’s health manual and my anti-aging book.

  1. Thank you, Sally, for this fantastic post about health. I wish I could have prevented this virus I have. It is still hanging on. Doctor said it takes 6 weeks to get out of my system. Sigh! It’s not as painful as previously, thank God. Hugs xx
