Outgrowing PA?

I know there is so much contradicting information out there on this, but wondering if anyone here has had a child outgrow it, and if so, what do you think contributed to that? We are avoiding all nuts, eating an anti-inflammatory diet, and eating foods rich in antioxidants (basically we eat a whole food, non-processed diet). Based on my research (and my own gut feeling), I think that by reducing internal inflammation (which is what leads to allergies, asthma, etc.) that we can reduce the chance of further allergies and maybe even reverse them....any thoughts? Experiences?
