sulfites

Sulfites are natural or added preservatives used in foods and beverages like wine, dried fruits, and processed items to prevent spoilage and maintain freshness. They work by inhibiting bacteria and fungi growth. Some people are sensitive to sulfites, experiencing allergic-like reactions such as asthma symptoms or skin issues, although these reactions are relatively rare. The FDA and other health authorities regulate sulfite levels to ensure safety in food products. If you're sensitive, reading labels can help you avoid products containing sulfites.
