My kids are lucky enough to not have any allergies themselves, but with nut allergies on the rise, friends in each of their classes since preschool have had allergies that could result in deadly reactions to certain nuts. While it's hard for families to ensure dishes are allergen-free in restaurants, we as parents can do our part at home to try and send our kids to school with nut-free lunches and snacks each day so that everyone stays safe.
For me, this starts in the grocery store when I'm purchasing ingredients for the week. Many of the processed foods available—including granola bars, cookies, crackers, and yogurts with toppings—are made in facilities that also process nuts. These items generally carry such a disclaimer on the package under the ingredients, but I've found it easiest to only purchase items for school made from whole foods and then pull together my own fun meals at home.
