What is a food intolerance?

An intolerance occurs when the immune system identifies certain food proteins as ‘foreign’ and produces antibodies to fight them off – the resulting symptoms can include:

  • low energy

  • abdominal pains

  • bloating

  • headaches

  • excessive gas

  • diarrhoea

Food intolerances can be developed at any point in a person’s life. Significant changes to diet or lifestyle can change how the body deals with food. These changes can develop over a long period of time.

Prolonged exposure to harmful foods and drinks laden with saturated fats, salt and sugar – or, in other words, a long-term lack of essential vitamins, minerals and nutrients – can have a negative effect on the strength of the immune system. Your gut is home to 70% of your immune system. You can support your gut health by reducing your “immune load”, and removing ingredients from your diet that may be causing it to overwork.


When you consider that a weakened immune system leaves the body and mind exposed to a wide range of harmful conditions, you can see how the symptoms of food intolerances and those of other conditions may be linked.
