Is Sodium Metabisulfite Safe For Human Consumption?

Sodium metabisulfite is generally recognized as safe for human consumption by the US Food and Drug Administration (FDA) when used in accordance with good manufacturing practices. However, some individuals may be sensitive or allergic to sulfites, which can cause adverse reactions such as hives, difficulty breathing, and anaphylaxis. Therefore, it is important for those with sulfite sensitivity to avoid consuming products containing sodium metabisulfite, which is commonly used as a preservative in various foods and beverages. It is also worth noting that excessive intake of sulfites may lead to health issues such as headaches, nausea, and diarrhea, so it is recommended to consume them in moderation.
