Celery

You may already know that peaches and apples can exacerbate symptoms in people with pollen allergies, but it turns out that celery can as well. Both cooked and uncooked celery can cause swelling of the throat, lips, and tongue, so if you have a pollen allergy, you’ll probably want to steer clear. And be sure to read the labels on packaged foods—celery is often an ingredient in soups and salad dressings.
