8 Dangerous Food Allergies

1. Tree nuts

Nut allergies are typically among the most severe food allergies, causing swift and dangerous reactions. You may be allergic to one or more hard-shelled nuts, including walnuts, pecans, almonds, cashews, Brazil nuts, and hazelnuts. Often, it's easier to steer clear of all of them rather than risk confusion about nut types.
