Oscar-winning actress and "Bond girl" Halle Berry is perhaps best known for her good looks and fashion sense. But she also lives with allergies on a daily basis. Berry is reportedly one of the 7 million Americans who are allergic to shrimp. About 7 million Americans have a shellfish allergy. Unlike other food allergens, a shellfish allergy often doesn't develop until you reach adulthood, so not having it as a child doesn't mean you won't get it later in life.
