Is Sodium Metabisulfite an Allergen?
Sodium metabisulfite is not a classic allergen like nuts or shellfish, but it is considered a potential allergen for some sensitive individuals. It is a type of sulfite, which can cause allergic-type reactions and asthma symptoms in susceptible people, especially those with asthma.
- Sulfite Sensitivity: Some people, particularly asthmatics, can experience reactions ranging from mild to severe when exposed to sulfites like sodium metabisulfite.
- Symptoms: Possible reactions may include breathing difficulties, hives, swelling, stomach upset, and in rare cases, severe anaphylactic responses.
- Labeling: Due to these possible reactions, sodium metabisulfite and other sulfites must be declared on ingredient labels in many countries when used in food above certain levels.
If you suspect a sensitivity, it is best to avoid products containing sodium metabisulfite and consult with a healthcare professional.
