Having to be low histamine and low glutamate plus cutting out legumes doesn't really allow us to explore other diets... On a positive note, his skin is really good now, about a week after stopping with the RPAH diet.
And giving him corn yesterday confirmed my suspicion that he is sensitive to glutamates - first sneaky poo since he had peas about a month or so ago!
Not that it matter too much, most high glutamate foods are high histamine as well (other than corn and peas pretty much!).
At least I feel like I'm getting somewhere finally. And tomorrow is the NAET appointment so we'll see how that goes. She is also naturopath and said she got rid of her eczema and her toddler son's intolerances with NAET so I hope for the best.
