Foods that you eat can trigger your allergies.

Are your allergy symptoms always awful? The foods you’re eating might be partially to blame. Many raw fruits and vegetables have proteins similar to those found in tree, grass and weed pollens, so your body responds to them in the same way.

Telltale signs of a so-called cross reaction with food or drink–which up to a third of people with seasonal allergies experience–include an itchy mouth and tongue and swollen lips. Consider cutting the following edibles from your diet (or peeling or cooking them before eating–which can reduce the effects) during allergy season to ride it out more comfortably.
• If you’re allergic to tree pollen, avoid almonds, apples, celery, cherries, hazelnuts, parsley and pears.
• If you’re allergic to grass pollens, avoid melons, oranges and tomatoes.
• If you’re allergic to weed pollens, avoid bell peppers carrots, celery, coriander, fennel, parsley and sunflower seeds.
• If you’re allergic to ragweed pollens, avoid bananas, cantaloupe, chamomile tea, cucumbers, honeydew, watermelon and zucchini.
