Health Impact
Some people are sensitive to sulfites and can have serious reactions to them ranging from wheezing to potentially life-threatening anaphylactic reactions. As a result, sulfites should be avoided by anyone with a sulfite allergy or sensitivity. People with asthma have between a 1 in 20 to 1 in 100 chance to having a sulfite reaction.
