Despite their widespread use and effectiveness, sulfite preservatives have stirred controversy, primarily due to health concerns. A small percentage of the population, particularly those with asthma, may experience allergic reactions to sulfites, which can include symptoms such as difficulty breathing, headaches, and digestive issues. Given the potential for such reactions, regulatory bodies, including the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), mandate that foods containing sulfites at levels above 10 parts per million must be clearly labeled. This transparency allows consumers to make informed choices regarding their dietary intake.
