Some may be environmental, but as OP mentions talking about future grandchildren's lives, there is likely a genetic component. We have fortunately advanced medically to where people with these kind of severe allergies can live long and happy, "normal" lives that would have been unthinkable 100 years ago which is fantastic, but also means these things are passed on.
I'm sorry OP, it's really hard. I have a friend whose son has 9/9 of the big ones and like 30+ others with anaphylaxis response and it's so extreme she has to homeschool. They're also doing to Food Allergy Institute and flying to LA to try to get even some minor relief. It's very scary and impacts every aspect of the family's life.
