Hi--
This remedy only works if your child has a sensitivity or allergy to gluten. Most people are not aware that allergies/sensitivities do in fact effect behavior---the child will either get very hyper or very angry. By removing the offending food from the diet, the child no longer has a strong reaction and the emotions dissipate. That is why so many kids with ADHD have to change their diet. They don't actually have ADHD, they have a food allergy that has gotten so bad that it is effecting their brain chemistry. Remove the food and the brain can then balance itself and the behaviors go away. It's also true of food additives---chemical dyes, preservatives, MSG, etc have been proven to cause hyper-activity in children. SO, if you are thinking about changing the diet you need to know what your child is reacting to. If there is a gluten sensitivity then your child will likely display some of the following: constipation or diarrhea (constipation is defined by not having a bowel movement at least once a day), frequent ear infections, post-nasal drip, annoying cough, puffy and/or dark circles under the eyes, any type of rash, including eczema, frequent tummy aches. But it may not be gluten causing the behavior---dairy is another one that many kids have a problem with. The top seven allergens are rounded out as dairy, gluten, soy, peanuts, tree nuts, eggs, shell fish. Almost all kids will react to chemicals in their food---so make sure you eat "real" food as much as possible.
You can also tell if your child has a food allergy/sensitivity if they spit up a lot as an infant OR if they wanted to eat constantly (sucking soothes an upset tummy).
If you do think it is gluten causing the problem I'm happy to talk to you about this further. My kids are both super sensitive---we don't do dairy, soy, gluten, any type of chemical food additive, and a few other things besides, so I'm an expert at changing diets!!
Good luck!
