Sulfite

Sulfites are chemicals commonly used as preservatives in foods and drinks, such as wine, dried fruits, and processed foods, to prevent spoilage and maintain freshness. Naturally occurring sulfites are produced during fermentation, but additional sulfites can be added for stability. Some people may be sensitive or allergic to sulfites, experiencing symptoms like headaches or breathing difficulties. Regulatory agencies require labeling of foods containing sulfites if they exceed certain levels. While generally safe for most, it's important for sensitive individuals to monitor their intake, especially if they have asthma or sulfite allergies.
