I've never thought on the boiling times before, but it could have something to do with it. When I make a beer next, (getting a kit for a honey ale) I'll make note of the hops and boiling.
My allergy problem hit me out of the blue when I was 35, at 41 me and the allergist are still trying to figure out what's going on.
I do know that some foods, I can't eat raw because of allergies, mainly vegitables, most notably tomatoes. Soy is a big problem for me, as is milk, but oddly enough not heavy whipping cream.
The doc also ended up running tests on me for nutrient deficiencies, and it turned out I was low in omegas, vitimin B, D and protien, despite being on an elimination diet, where in I was eating mainly beef, salt and water, since those were safe for me. Further testing revealed a leaky gut, and a virus called h. Pylori.
Long story short after treating those issues, a lot of my allergies disappeared, but one or two still remain.
