Recognising food intolerance symptoms

The first thing to understand is that food intolerance symptoms manifest themselves in different ways in each individual. It is this fact that makes it quite tricky to get an accurate diagnosis when you suffer from non-allergic food hypersensitivity, which is the term some medical professionals use to describe the condition.

Whereas someone else who is sensitive to eggs may have no skin problems, but suffer from chronic diarrhoea when they eat them.

To complicate things further often the symptoms of food sensitivity are very subtle. A fact that makes it quite difficult for people to recognise what is going on and realise why they are feeling so unwell.

If you suffer from an egg allergy it is all too obvious, because you are likely to go into full anaphylaxis if you inadvertently eat something that contains even a tiny bit of egg. The symptoms are serious, for example difficulty breathing, severe swelling of the mouth and airways and huge hives. Basically, with a full blown food allergy the body goes into shock and starts to shut down. Whereas, with food sensitivity the symptoms can be very mild, and, therefore, difficult to detect.

The role of an elimination diet in recognising the symptoms


If you are feeling unwell and are suffering from any of the above symptoms it could be that you are indeed sensitive to certain foods. The best way to find out is to keep a food diary. By noting down exactly what you eat and how you feel, two or three times a day, you will soon to be able to see if there is a pattern.

If you notice that you are suffering from any of the above symptoms after eating certain foods you probably have some form of non-allergic food hypersensitivity. Now that you know that and have some idea of which food products are causing you to feel unwell you can take the next step, which is following an elimination diet.
