Symptoms of food intolerance

If the answer is yes, you may be suffering from food intolerance!

Food intolerance is different to food allergy. Here is a brief explanation of the differences:

Food intolerance and food allergy in brief

Food Intolerance Food Allergy
  • Reactions are usually delayed and symptoms may take several days to appear.
  • You can be intolerant to several different food groups at the same time.
  • Sufferers can experience multiple symptoms, from migraine to bloating, diarrhoea, lethargy and a general feeling of unwellness.
  • Reactions usually occur quickly, with a maximum of 2 hours after exposure to the ‘reactive’ food.
  • Food allergy involves the body’s immune system and is a reaction to a specific food.
  • Symptoms include: difficulty breathing, rashes, swelling, runny nose and anaphylactic shock. These can potentially be life threatening.

You can determine if you have food intolerance by doing the quick and easy Food Detective test.


Food Detective™ is a blood test for food antibodies (IgG) that can be
conveniently used in the clinic of a health professional. You don’t
have to send off a sample and wait weeks to receive results from a
testing laboratory.

Email from patient:

“Thank you so much for your advice and help. I do feel much better and I know it is due to the outcome of the diet and supplements. I feel ready for the third age!!! But able to keep working a bit longer. I know that my job is stressful but I am coping so much better. Thank you!!!”.

Why Food Detective Rocks

  • The blood test is a great motivator for clients to change their diets.
  • It is easier and faster to get results (than following an elimination diet)
  • The positive changes that patients experience after eliminating their intolerance foods can be life-changing.

With love, light and appreciation
