Tho' asthmatic, I musn't be allergic to nuts as my wife sleeps next to me and I don't get any reaction.![]()
i reckon my wife has gone the same way, exposure to me over the years has dulled her nut allergy from serious face swelling and breathing difficulties to just some slight swelling and a tickly throat.
These allergies tend to be a reaction to proteins within the food. If a squirrel eats a nut, it will digest it and the proteins will largely be broken down into smaller peptide chains and, ultimately, amino acids. I guess there could still be an allergic reaction if any of the whole protein was still in the gut, on the skin/mouth/etc.
