<unk>  produces symptoms when an affected person eats certain fruits, vegetables, and nuts. Some individuals may only show<unk>  to one particular food, and others may show an<unk> c response to many foods. Individuals with an<unk>  to tree pollen may develop<unk>  to a variety of foods. While the tree pollen<unk>  has been worked out, the grass pollen is not well understood. Furthermore, some individuals have severe reactions to certain fruits and vegetables that do not fall into any particular<unk>  category. When tropical foods initiate<unk> ,<unk>  to latex may be the underlying cause. Because the<unk> nic proteins associated with<unk>  are usually destroyed by cooking, most reactions are caused by eating raw foods. The main exceptions to this are celery and nuts, which may cause reactions even after being cooked. Cross reactions<unk> es to a specific pollen are usually associated with<unk>  reactions to other certain foods. For instance, an<unk>  to ragweed is associated with<unk>  reactions to banana, watermelon, cantaloupe, honeydew, zucchini, and cucumber. This does not mean that all sufferers of an<unk>  to ragweed will experience adverse effects from all or even any of these foods. Reactions may be associated with one type of food, with new reactions to other foods developing later. However, reaction to one or more foods in any given category does not necessarily mean a person is<unk> c to all foods in that group. * Alder pollen: almonds, apples, celery, cherries, hazel nuts, peaches, pears, parsley, raspberry, strawberry * Birch pollen: almonds, apples, apricots, bananas, carrots, celery, cherries, chicory, coriander, fennel, fig, hazel nuts, kiwifruit, nectarines, parsley, parsnips, peaches, pears, peppers, plums, potatoes, prunes, soy, strawberries, wheat, jackfruit; Potential: walnuts * Grass pollen: fig, melons, tomatoes, oranges, celery, peach * Mugwort pollen : carrots, celery, coriander, fennel, parsley, peppers, sunflower, mustard * Ragweed pollen : banana, cantaloupe, cucumber, green pepper, paprika, sunflower seeds/oil, honeydew, watermelon, zucchini, echinacea, artichoke, dandelions, honey (if bees pollinate with pollen from wild flowers),
