Sulfites in foods are often placed there as a preservative.
While most governments have banned the use of sulfites in foods like fresh fruits and vegetables, they are still commonly used to preserve dried fruits, wine making, and to preserve seafood and other meats.
Reading food labels is important if you are trying to eliminate the compounds from your diet.
See What are Sulfites for a list of common ingredient names and numbers for sulfites.
However, sometimes they aren’t always included in a list of ingredients, especially if they are in a sub-ingredient like dried coconut or dried fruit.

Although no foods have a high concentration of sulfites, when many of the above foods are combined and eaten regularly, some people can have moderate to severe reactions to the chemical.
Luckily, because of increased awareness of the dangers of these preservatives, many manufacturers are producing foods in the above list that are free of them.
