People with sulfite-sensitive asthma experience asthma symptoms when they eat foods or drink beverages that contain sulfites. Estimates regarding the prevalence of sulfite sensitive asthma vary. Most reactions happen due to inhalation (breathing in) of sulfur dioxide that comes from sulfite-containing foods you eat or drink.

The toxic effects of sulfites can trigger allergic reactions. Symptoms of sulfite sensitivity include asthma, hives, tissue swelling, abdominal pain, nausea, diarrhea, seizures and shock resulting in death. Levels as low as one part per million can trigger asthma . Symptoms also include: 1 Severe respiratory reaction 2 Flushing 3 Feeling of temperature change 4 Vomiting 5 Difficulty swallowing 6 Dizziness 7 Contact dermatitis

Sulfites are also known to activate a certain cell of inflammation leading to the production of oxygen radicals. Hence sulfite levels are closely regulated in the body. Sulfites have been associated both with occupational disease and death.

When sulfur dioxide (a by-product of fossil fuel combustion) comes into contact with fluids that line the airway, it is converted into sulfite. Metabolism of sulfur-containing amino acids also results in the production of sulfite, but an enzyme, present in tissue, detoxifies sulfites by oxidizing them into sulfates.

Food manufacturers and processors are legally required to disclose the presence of sulfiting agents in concentrations of more than 10 parts per million, whether the sulfites are used during processing or are components of an ingredient in the food.

Condiments, jams, gravies, dehydrated or precut or peeled potatoes, molasses, shrimp, and soup mixes. Beverages such as wine, beer, hard cider, fruit and vegetable juices, and tea. Processing of food ingredients including beet sugar, corn sweeteners and gelatin can also generate sulfites.
