Food Intolerances

With information on research, testing and appointments

What Causes Food Sensitivities?

Good Question!  We are going to focus in this section on Delayed Food Intolerances and Sensitivities

We at Perth Allergy Clinic are asked many different questions on a day to day basis about this complex topic.  We help lots of sufferers with symptoms such as bloating, gas, hard distended abdomen, eczema, skin rashes, migraines, brain fog, mood swings and the symptom list goes on every single day.

Food sensitivities do not happen overnight they develop over a long period of time.  Lifestyle and diet are the major contributors.

It all starts within the gut microbiota various factors such as stress,  genetics, environment, diet and potential antibiotic intake, may all contribute to the alteration of the gut microbiota.  Over time there is a break down of the intestinal barrier whereby it becomes permeable and allows micro particles of food, bacteria and viruses to seep through the gut barrier and activate immune responses.  Intestinal permeability is one of the major factors for food intolerances and sensitivities to develop.

Unfortunately due to the nature of food sensitivities there is not a ‘catch all health protocol’.

There are many reasons why the gut can become permeable.  The first step is to find out why? Just as there are many reasons for poor gut health there are also many solutions.  We tailor make our gut health protocols to decrease the inflammation, heal the gut lining, recommend the most specific probiotic and most importantly suggest the correct Food Intolerance Test for you.

Bacterial and viral infections may also suppress immune responses by triggering inflammation, impairing gut permeability and thereby facilitating the development of food sensitivity (Caminero et al, 2019).

Reduced levels of beneficial bacteria in the gut can predispose individuals to increased incidence of developing bacterial and viral infections (Caminero et al, 2019). Studies have further identified that viral infections may also increase susceptibility to developing food sensitivity by breaking down oral tolerance to dietary proteins (Verdu & Caminero 2017).

It has been hypothesised that increased intestinal permeability to larger proteins result in elevated concentrations of IgG antibodies due to an immunological reaction being triggered (Neuendorf et al. 2019).

Here is a Table outlining the typical differences following exposure to a “True Allergy” (IgE)  and “Food Intolerance” (IgG).

Understanding Food Intolerances

Food intolerances can be frustrating and confusing!  Why???

  • Because they are hard to pinpoint!!!
  • Symptoms can manifest between 24 – 72 hours after eating
  • Manufactured foods contain “hidden ingredients”

Ask yourself, can you honestly remember everything that you have eaten or drunk in a 72 hour window? 

The possible manifestations of  food intolerances are enormous and often non-specific. Food reactions may cause bloating, gas, constipation, diarrhoea, alternating bowel, eczema, psoriasis, skin rashes, brain fog, weight gain to name just a few!

We have been looking after sufferers of food intolerances for over 20 years and have gained a wealth of knowledge over this time.

We so often hear the same statements

“I am fed up of my bloating – I have put up with it for years – now I will do something about it.”

“This itchy rash is irritating it comes and goes and I don’t know what is causing it?”

Regardless of the cause, the impact on an individual’s quality of life can be miserable!  Understanding and navigating a course to deal successfully with food intolerances can be challenging as there are many areas to consider.   One of the first ways we can understand as to what is making us uncomfortable or sick is to take a simple food allergy test to detect these implicated foods or food groups.
