Testing Methods for Food Intolerance

Types of Testing For Food Intolerance

Have you had clinical tests for food intolerance, followed all the instructions - but still suffer with symptoms? Clinical testing frequently gives 'inconclusive' answers - requires a whole series of tests.

But the Journal Method is fast and accurate.



Clinical Tests from your Doctor

Your medical doctor (GP) may use:

    • Several kinds of blood tests
    • Hydrogen breath testing*
    • Allergy testing (e.g. by skin pinprick method)
    • Gastroscopy (tube guided into stomach while under anaesthetic)
    • Intestinal biopsy (small tissue sample taken under anaesthetic)
    • Stool (faecal) analysis
    • Skin sample analysis (e.g. with flaking skin infections)
    • Genital swab (e.g. for fungal conditions)

*No longer practised by many doctors who cite unreliable results

Tests from a Naturopath

A naturopath or alternative medicine practitioner may use:

    • Iridology (diagnosis by looking into the iris of the eyes)
    • Homeopathy - examination of the eyes, skin, tongue and pulses
    • Vega testing (now discredited among many professionals)
    • Other methods

Most clinical testing relies on your doctor's interpretation of the results - and that many tests return 'inconclusive'. You may need further series of tests to gather more information. Unfortunately, conclusive results are not often found using clinical tests.


I think I might have food intolerance: What should I do?

Beginning with our free e-book, we can help you establish if you are suffering from gluten or wheat intolerance or if your symptoms indicate an intolerance to dairy, fructose or yeast. You may even be suffering from more than one food intolerance.

The research indicates doing nothing can be a risk. Undiagnosed food intolerance can cause serious long-term health problems like osteoporosis, anaemia and many others. Sign up for the Free E-book 'How to Tell If You Have Food Intolerance'


Am I affected? How common is food intolerance?

Many people feel they are not affected by food intolerance. But the research evidence says otherwise. Research says 75% (3 in 4) of all people have some type of food sensitivity. A few statistics:

>> 3 in 4 have lactose intolerance (even if they are unaware)

>> 15% are unable to digest gluten (difficult to identify and often misdiagnosed)

>> 1 in 3 cannot tolerate fructose (often misread as other illnesses)

>> Up to 90% of Asians have dairy sensitivity

>> Inflammation caused by Nightshades, legumes and yeast infection is often misdiagnosed


Which intolerance? ... (You can't tell from symptoms alone)

It would be convenient if a certain group of symptoms meant a particular intolerance. But that's not the case.

Symptoms from each intolerance overlap with each other like this ....

  • Say you suffer headaches:
    • You could be casein, gluten or nightshade intolerant
  • Or say you have Irritable bowel (IBS)
    • You could have lactose, fructose, legume or gluten intolerance

How to sort them out?

> Track your foods - against changes in symptoms

> Record what you eat ... with our guidance

> Discover your food intolerance - know for life
