Food Allergens

Most allergens that induce asthma symptoms are ones that you breathe in. Food is a less common cause. But if you experience asthma symptoms after eating processed potatoes, shrimp, or dried fruit or when drinking beer or wine, you may be sensitive to the sulfites present in these foods, although sulfite allergy is a rare asthma trigger. Sulfites are used to preserve foods and beverages. If your asthma seems to be triggered by sulfites, avoid food and beverage products that contain these preservatives, and read ingredient labels before eating processed foods.
