Hi Brandie,
New information is coming out everyday about the effects of food allergies and sensitivities. The sensitivities are different than the simple blood test or skin tests for allergies to food. With sensitivities they have digestive problems with certain proteins they can't digest, so they test by taking the stool and doing a comprehensive analysis. It make more sense to test this way by finding out what the body is expelling.
Also kids that fall on the high functioning end of the autistic spectrum disorders usually have a lot of emotional issues. They are can be creative and intelligent, but super sensitive and take things very literally.
If you want to research this angle a little more please take a look at a website inspired by my daughter Alexis (she will be 4 this month). There is free information and tons of links dealing with food allergies/ sensetivities.
You can email me from the site if you have any questions at all....it can be a lot to sort through, so I have made it a little easier by condensing some of the facts. Plus diet is the most basic way to get the body to function properly most of the time and without medication.
Good luck,
A.
