I cannot eat any fresh fruit, every time i do i throw up, why is that?

Some thoughts...: This kind of situation might happen if a person has become allergic to certain fruit and/or has unintentionally developed a vomiting reflex to eating fresh fruit... which can happen after a real vomiting episode during the eating of fresh fruit. Later vomiting episodes may then be due to a subconscious memory of prior vomiting, and may not have anything to do with allergies.
