Some of you may have read this article based on a study by Johns Hopkins University, but if you haven't, check it out, here.
According to the story, one of the most common food allergies is to peanuts. Other studies have shown that tree nut allergies have grown right alongside peanut allergy. (The article doesn't mention tree nut allergy, but other sources have noted this connection.) So if people try to tell you that no one had a peanut allergy when they were a kid so therefore, they can't really be so numerous (an illogical argument to begin with), you can point them to this story.
I'm glad the LA Times reported on this increase because food allergies are altering the landscape of everything regarding eating: agriculture, restaurants, prepared food products, grocery stores, even how items are displayed before purchase due to cross-contact concerns.
Besides just your own family members (or yourself) do you find more people you meet either have a food allergy, know someone with one or care for a child with a food allergy? In my own experience, I've found this to be increasingly true in the last five years. What about you?
