What is food intolerance?

A food intolerance or sensitivity is difficulty digesting certain foods and having an unpleasant physical reaction to them.

What are the differences between Allergies and Intolerances

A food allergy:

  • Is a reaction from your immune system – your immune system mistakenly treats proteins found in food as a threat
  • Can trigger various allergy symptoms that come on rapidly
  • Is often to particular items – common food allergies in adults are to fish and shellfish and nuts, and in children to milk and eggs as well as to peanuts, other nuts and fish
  • Can be serious
A food intolerance:
  • Doesn’t involve your immune system – there is no allergic reaction, and it is never life-threatening
  • Causes symptoms that come on more slowly, often after many hours
  • Only results in symptoms if you consume reasonable amounts of the food (unlike an allergy, where just traces can trigger a reaction)
  • Can be caused by many different items
Food intolerances and sensitivities more often display symptoms that are related to the digestive system. Individual extreme cases are also linked to chronic conditions such as irritable bowel syndrome and chronic fatigue. The most common symptoms include:









Changes in bowel movements

Reducing symptoms through elimination

A large number of food intolerance symptoms can often be reduced through the implementation of a food elimination diet and improved gut health.

Eliminating foods which are believed to be the cause of symptoms can allow the digestive system time to adjust and reset.

There also could be a need to improve gut health and rebalance gut bacteria levels also in this time.


Allergies and Intolerances/Sensitivities are different and you should consider the following:


Allergies and Intolerance/sensitivities are different conditions presenting with different symptoms and causes


Intolerances/sensitivities (food and non-food) symptoms can occur up to 72 hours after contact


Allergies usually present symptoms rapidly (up to a few hours) and are commonly at the more severe end of the reaction scale.


Intolerances/sensitivities are mostly uncomfortable and embarrassing and do not usually present any serious risk to overall health


Allergy symptoms can be serious and even life-threatening in some cases
