Food Intolerance


Do you suffer from the following symptoms on a regular basis?  Food Intolerance.

  • Gastrointestinal: Bloating, excess wind, abdominal discomfort, constipation, diarrhoea, nausea, reflux or mouth ulcers
  • Skin: Hives, eczema
  • Respiratory: Hayfever, asthma, sinus congestion
  • Nervous system: Restless legs, irritable bladder, headaches, migrains
  • Babies or children suffering from colic, reflux, disturbed sleep, eczema or recurrent nappy rash
  • Orofacial Granulomatosis

You may have irritable bowel syndrome, food chemical intolerance, or both. All the symptoms mentioned above are commonly reported in individuals with a food intolerance. 

The terms food intolerance and food allergy are commonly confused. It is important to note that food intolerance does not involve the immune system and it cannot be diagnosed from allergy tests. It will not cause allergic reactions such as anaphylaxis. 

Irritable Bowel Syndrome (IBS)

IBS is common and it affects 1 in 5 Australians. It is a long-term condition that affects the large intestine. The symptoms of IBS can be embarrassing and distressing and it is not often talked about. The causes of IBS are not well understood, but we know that it can be triggered by stress, infection, food intolerance or some medications.

If you think you have IBS, it is important that you see your GP for a full health assessment to rule out other serious conditions such as cancer or Coeliac disease. A diet low in FODMAPs is now recommended as the most effective dietary management therapy for IBS. The diet has also been proven to reduce fatigue, lethargy and poor concentration from a number of research studies. Read more about IBS and the low FODMAP diet here.

Food Chemical Intolerance

Food chemical intolerance can cause a range of reactions in sensitive individuals and affect multiple aspects of a person’s life. The reactions are triggered by food chemicals that irritates nerve endings in different parts of the body. Natural food chemicals such as salicylates, amines and glutamates are found in many food, including healthy food such as fruits and vegetables. Foods which are aromatic, rich, spicy and highly flavoured are likely to contain high amounts of food chemicals.

Food chemical intolerance may be inherited and changes in environment can trigger reactions. Examples include a sudden change in diet, following episode of gastroenteritis or glandular fever or during pregnancy and lactation.

Breastfed babies can suffer from food intolerance reactions due to chemicals from the mother’s diet passing through the breastmilk, causing colicky behaviour, eczema and nappy rash. Babies are more sensitive as a result of their immature gut and nervous system. Fortunately, tolerance improves as they grow and their body matures. 

The most common treatment for food chemical sensitivity is the Royal Prince Alfred Hospital (RPAH) Elimination Diet.
