Problems with the RAST test for Gluten/Wheat. Part 1: Testing the Test.

Saturday, March 27th, 2010

One out of 133 individuals are estimated to have Celiac Disease.  Yet only 1% of the affected population have been diagnosed.  Why is this?  One of the reasons is possibly the test requested by physicians.  The most common blood test requested for allergies is the RAST test or RadioAllergoSorbent Test.  Blood samples are taken to see if the blood contains IgE (Immunoglobulin E) antibodies that attached to an allergen’s surface.  While the test is very safe, it can give “false negatives”.  One needs to have the allergen in the blood stream for it to react; and it needs to be recent!  How recent is the question?  To answer this question, I asked my youngest son to volunteer to be my “guinea pig”.  He just started going to a new physician  who was not familiar with Celiac Disease. He made an appointment for his blood test for Monday.  The Friday before he started a hi-gluten diet.  He ate meals that consisted of: pasta, pizza, soft bread, and drank hi-gluten beer.  By Saturday night his stomach was rebelling and he had diarrhea.  On Sunday his stomach really started to hurt.  By Monday morning he was so tired he could hardly get out of bed.  He went for his blood test, then returned to his gluten-free diet.  The next week he went for his results.  The physician proudly announced to him that his test result of 14 was negative (My result was .7 ).  My son then sat his physician down and educated him about the results.  Why did the test give a “false negative”?  Combined with my son’s symptoms, was 14 really a negative result?

Attention Deficit Hyperactivity Disorder (ADHD) and Dietary Factors

Monday, March 15th, 2010

An acquaintance of mine has 3 children, all with the disorder ADHD.  She has two boys and one girl.  Each child has a different subtype of ADHD.  They are always sick, especially the youngest.  This eight year old boy has been plagued with asthma, bronchitis, and stomach aliments.   This last year he only gained one pound.  This is the time in his life when he should gain at least 10 pounds.  He also looks very, very ill.  Previously, I suggested to his mother that he probably had Celiac disease due to his lack of growth and stomach distress, while lactose intolerance may be causing his respiratory problems.  I further suggested she get him tested.  Finally, a year after my suggestions, she went to a ADHD focused physician and had her son tested.  He test positive to gluten/wheat, lactose (cow’s milk), and corn.  He is also sensitive to food colorings.  I do not think that this mother fully understands the scope of changes the needs to take place in her family.  There is a more than 50 per cent change that the other two children also have the same allergies.  Since she will be cooking the same for everyone in the family, the other children should get the benefits of eating allergy free.

For years the medical profession has ignored the relationship of nutritional factors such as : food allergies, food sensitivities, food additives, refined sugars, and fatty acid deficiencies to ADHD.  Finally the pendulum is swinging the other way.  More studies are examining the relationship between food sensitivities and ADHD.  The research results are supporting this relationship.

One more thought; ADHD is a brain disorder causing negative behavioral patterns.  Is it possibly the brain’s response to food that it deems poison?  The stomach’s reaction will be pain and diarrhea, the respiratory system will respond with allergies, asthma and other symptoms.  So how does the brain respond to toxins in the form of food?  What if the response is abnormal behavior?  Does that sound like Autism and ADHD to you?  What are you feeding you and your children: Food or Toxins?  If you eat mostly processed food the answer is : Toxins!
