As this week is Food Allergy Week, I’ve asked naturopath Nicole Hannan to give us the run down on allergies and what we need to know. – Cyndi.

Over to Nicole….

In order to really understand what it is like for those living with allergies, it is so important for us to have empathy. Empathy definition Think for a moment about the big events that most people celebrate – Christmas, birthdays, weddings, family gatherings etc. What is one of the main focuses of all of these? FOOD! How would you feel if you had to bring your own food to all of these celebrations for fear that your life might be in danger if you ate something? This is an unfortunate reality for those living with severe allergy. It is not only a logistical nightmare but can be extremely isolating. I have heard many complaints from parents about not being able to pack nuts in school lunches, but what if it was your child who could die because of accidental exposure to a food allergen?

So what exactly is an allergic reaction?

When the immune system reacts to substances in the environment that are harmless for most people an allergic reaction occurs. This involves mast cells, which are found in the skin, gut, lungs, nose and eyes. Mast cells are designed to protect our bodies from potential invaders and are filled with irritant chemicals including histamine. When an allergen enters the body, an antibody response is triggered. These antibodies attach themselves to the mast cells, causing them to ‘degranulate’ or spill their contents into the tissues, resulting in the redness, swelling and irritation of an allergic reaction. This diagram demonstrates why I am a Naturopath and not an artist… It looks more like a spilled bag of marbles than a mast cell but hopefully you get the idea! Allergens and the eddect on cells

The low down on allergies in Australia

Allergies are very common and increasing in Australia, with approximately one in three people being affected at some time in their lives. Food allergy alone affects around 8% of children, 10% of infants, and 2% of adults with numbers continuing to increase. Most of the statistics around allergy focus on food but it is important to remember that environmental and chemical allergens can also cause severe reactions. Australia is not alone in the rapidly increasing occurrence of allergic reactions. In the last ten years hospital admissions for allergic reactions in Australia, the USA and UK have doubled, and in Australia, admissions due to food allergy, in children aged 4 years and under, has increased 500%. This is an alarming rate in such a short period of time! Allergy info you need to know

Does allergy run in families?

Yes it does. Atopy or atopic disease is a term used to describe a family likelihood of developing allergies when other family members suffer from allergy or asthma. Eczema is also a common characteristic of atopic disease. This tendency to develop allergic diseases is a genetic predisposition and when atopic people are exposed to certain foods, chemicals or environmental triggers they can develop an immune response that leads to an allergic reaction.

How to save lives!

This is where we really need to get serious and face the reality that for many people their allergies are life threatening. Anaphylaxis is the term used to describe allergy that can be lethal. Let’s look at the signs of anaphylaxis and how a quick response can save lives. A great ‘Action Plan for Anaphylaxis’ chart is available to download from the Australasian Society of Clinical Immunology and Allergy. Here is where the empathy and action come together to save lives.

  1. Reduce exposure risk for those with known anaphylaxis by being aware of potential triggers.
  2. Know the warning signs and be familiar with an action plan.

Signs of anaphylaxis We have just scraped the tip of the iceberg with this one, so much more to explore starting with the next installment on the blog: Allergy vs Intolerance – What is the difference? Nicole Hannan, Naturopath BSc. Sports Medicine, BHSc. Naturopathy
