Does Sodium Metabisulfite Cause Cancer?
Sodium metabisulfite is a common preservative used in foods, wines, and some pharmaceuticals. Its main role is to prevent spoilage and maintain product freshness.
Possible Cancer Risk
- There is no strong scientific evidence that directly links sodium metabisulfite to cancer in humans.
- International health organizations, such as the World Health Organization (WHO) and the U.S. Food and Drug Administration (FDA), consider it safe for use in regulated amounts.
- Studies have mainly focused on possible allergic reactions or respiratory issues, especially in people with asthma, but not on cancer.
- Some animal or cell studies have found that very high doses can damage cells, but these doses are much higher than what is used in food.
Conclusion
When used within approved limits, sodium metabisulfite is not known to cause cancer in humans. It is generally recognized as safe by food safety authorities. If you have a known allergy or sensitivity to sulfites, it's best to avoid products containing this additive.
