Because the general medical community has yet to conclusively confirm that additive sensitivities exist apart from rare sulfites allergies, there are no established treatment or prevention methods for additive sensitivities. However, if a person is diagnosed with an additive sensitivity by a physician, the most basic and effective way of preventing further reactions is avoidance. This means not eating foods that contain any of the additives to which they appear susceptible.

Avoidance is not easy. Ingredient lists must be carefully read and people must be aware of any alternate names for the problem additive. For example, an individual who reacts to sulfites should avoid sulfur dioxide, sodium sulfate, potassium sulfate, bisulfate and metabisulfate. A physician or dietician should be consulted to determine which types of additives should be avoided. Patients with sulfite allergies should also be aware of foods that naturally contain sulfites.

Foods that commonly contain sulfites, either naturally or as an additive, include:

• Lettuce
• Tomatoes
• Asparagus
• Eggs
• Onions
• Garlic
• Chives
• Leeks
• Dried fruits
• Canned vegetables
• Soy products
• Baked goods
• Jam
• Gravies
• Molasses
• Maple syrup
• Shrimp
• Salmon
• Dried cod
• Soup mixes
• Corn starch

Beverages that may contain sulfites include:

• Wine
• Beer
• Hard cider
• Fruit and vegetable juices
• Tea

Individuals with additive sensitivities should also learn to inquire at restaurants about cooking methods that might present a problem. Parents may want to warn school personnel, caregivers, friends and other people who frequently interact with children who may have an additive sensitivity.

Though there is no known drug treatment available to prevent a food additive reaction, there are certain treatments available for the symptoms themselves. A physician will often recommend an antihistamine to provide relief for reactions to sulfites such as, hives, sneezing, runny nose and gastrointestinal symptoms. For relief from symptoms associated with asthma, a physician will often recommend bronchodilators.

Some individuals appear to be dangerously sensitive to certain additives (e.g., sulfites). It is a good idea for these people to wear a medical alert bracelet or necklace to alert healthcare providers in the event of an emergency. Physicians may also recommend that individuals who could potentially have an anaphylactic response carry a syringe of epinephrine and know how to self-administer the medication.
