Sulphite allergy

Sulphites are a food additive used to preserve and maintain food colour and shelf life. They occur naturally in some foods and the human body and are safe for most people to eat. Sulphites are also used to bleach food starches and are used in the production of some food packaging materials like cellophane.

People with sulphite allergies need to avoid almost all packaged food. Fresh fruits and vegetables must be washed extremely well to eliminate residues.
