Food Intolerance Tests




This morning when I was digging up some information discovered a Food Intolerance Test Report of August 2011. I remember it was quite expensive to get one at the time. It uses Genarrayt Microarray ELISA technology to detect food-specific lgG antibodies through a blood test. One gets a very fancy report that is signed off by a licensed Pathologist.

Here is more information about the process:

Principle of the test
Up to 221 foods have been microarrayed onto each of 16 nitrocellulose pads on a glass microscope slide. Non-specific binding sites are blocked with blocking buffer prior to incubation with diluted patient whole blood, serum or plasma. After washing away unbound serum components, anti-human IgG conjugated to horseradish peroxidase is added to the pads, and this binds to food extract-bound antibodies in the second incubation. Unbound conjugate is removed by washing, and a solution containing 3,3,5,5-tetramethylbenzidine (TMB) and enzyme substrate is added to trace specific antibody binding. After washing with distilled water, the slides are dried by centrifugation prior to scanning. The optical densities of the standards, positive and negative controls and samples are measured using a high resolution flat bed scanner with associated software. Optical density is directly proportional to antibody activity in the sample.

The 221 foods are listed in a descending order of highest anti-bodies. Those above 30 are in the red zone and it is suggested to eliminate those foods over a period of six months to a year and then to re-introduce them gradually in small quantities. Then there is a yellow category from 24 to 29 where one should be cautious with those foods. The balance of the 221 foods tested are grouped in a safe green category in descending order from 22 to zero.

I'm lucky in that more than half of the foods tested zero, however found some real shocks with the red zone foods. Foods that I've been consuming regularly over a long period of time such as:
Eggs
Cow's Milk
Wheat and wheat bran
Rice
Peas
Sesame seeds (I love tahini)
Pineapple (one of my favourite fruits)
Oats
Potatoes
Almonds (that was a BiG surprise)

32 out of the 221 foods were in the red zone.

Then another shocker in the yellow zone (8 foods out of the 221 in this zone) included cinnamon, soya and lemon. Also radish.

The rest of the foods were under 23 and in the green zone.

Checked my honey, and I tested zero for honey at the time. Also zero for all red meat, chicken and fish with the exception of crab. Dates scored zero, so do avocado and grapefruit, two of the fruits I've been consuming quite a bit off. Tomato scores quite high at 18. Should have more polenta as I do like it and it has a zero score.

Is there any particular reason why you did this test?

Probably more out of curiosity really. It was two years ago during the summer. At the time my digestion was not as good as it should be, so someone suggested I see this doctor who then tested me for my responses to certain foods. Quite fascinating really, how I tested positive for the foods I was enjoying the most at the time. One thing I learned was that we really need to have a great variety of foods in our diet. If one over consumes wheat for example, the body could build anti bodies. I find my digestion very much improved when I dropped wheat. Particularly bread and crackers. As well as pastries. Rice is another culprit. Particularly in large quantities.

The Japanese has a very good way of eating. Very small morsels of an enormous variety of foods in a few courses. And under eating rather than over eating. A friend of mine was there recently and commented on how small the helpings had been. He lost weight during his visit. Very Happy
