Connection between peanut allergies and add, asgbars aned autism?

can smelling peanuts or peanut butter cause an allergic reaction to someone who has an allergy to peanuts?

My 5 year old son is autistic and has a sensitivity to peanuts, not a true allergy but a food intolerance. It is true that some kids diagnosed with autism have had their autistic traits reversed by diet alone. This is rare. A well-trained clinican can pick out "recovered" kids because some traits have been diminished but not totally eliminated. Their social and behavioral issues will follow them the rest of their lives. I had to remove most of the food he eats because his body started to make antbodies to these. These foods were causing a drug like effect in my son. 3 weeks after I removed the foods, he started to calm down. He no longer craves for peanut butter, bread or butter.
Autism caused by food allergies is the easiest one to "cure".
Jenny McCarthy's son had a horrible reaction to gluten and casein and her son is not alone. My son's stool will turn a sickly yellow from gluten.
Some schools have a peanut free table in the lunchroom or have even banned peanuts in the school. This is because some kids will have a severe reaction that can lead to death. One person died after being kissed from someone who had eaten peanuts recently.

My niece can not be in a room with an open bag of peanuts due to her peanut allergy, she is that sensitive but she is not autistic.I have wondered if children diagnosed as having autism but are claimed to be cured by diet alone,in fact do not have autism but that the food allergy symptoms in that child mimic autistic symptoms.Just a thought.
