This is one allergy that appears to be unforgiving. Deadly reaction that occurs VERY quickly.
As I posted earlier, my son, who is now 31...has a severe peanut allergy....as well as seafood, shellfish, tomato, all citrus fruits, peas, beans and eggs...and virtually all nuts. His whole life...I told him...ASK what is in the food or what it is cooked in. If in doubt...order meat and potatoes...which has really worked out well. Of Couse many cosmetics for women has walnut shells in it....so now i guess the added question is what is on your lips...lol. It is up to the parent to teach the child what he can or can't eat......oh did i mention the skin allergies...to most lotions and creams....fun fun fun.
I took it as my responsibilty to make sure he had what he could eat...and stayed away from what he could not. It was NOT MY JOB to police what others ate...only what he ate. Hey, it worked out well....he is still alive.
