A recent study showed that only one out of 500 people who thought they were allergic to chocolate actually tested positive. Allergies to chocolate are quite rare. It is typically the case that the person is in fact allergic to milk and dairy products or other ingredients commonly found in chocolates. Typical highly allergic ingredients may include soy, milk, gluten or nuts. Some people can be allergic to cooked and processed chocolate but are not allergic to Raw Cacao.
