Chocolate allergy

Allergy to chocolate or cocoa is very rare. A survey shows that only 1 out of 500 who believe they have chocolate allergy, in fact tested positive to the chocolate.

Most probably these reactions are due to other ingredients of chocolate such as milk, soybean, lecithin, gluten and nuts.

There are 380 known additives in chocolate. They can have pleasant and unpleasant effects.
