Allergies come in different forms, so not everyone who has a pollen allergy is allergic to tree pollen. A palm tree allergy is indicative of your bodyâs reduced immunity to pollen, which can sometimes be genetic. When your body comes into contact with tree pollen, it releases histamine, the aggravator of common allergy symptoms. There are certain types of palm trees that donât exhibit pollen, such as Phoenix palms, so it is always important to identify the differences before planting any new trees in your yard.
Coconut allergy is relatively rare. Coconut is a very different plant from peanut or tree nuts. The presence of the letters nut does not mean that coco-nut will trigger an allergic reaction in people allergic to peanut or tree nuts.he substances triggering allergic reactions to food are proteins. If a person is allergic to one protein present in one food only (e.g. coconut, dairy products, hen's egg), then an allergic reaction can only occur if they eat that one food.
