Wine (and other fermented foods, like beer, pickles, yogurt, and sauerkraut) may naturally contain a substance known as histamine. Since histamine is also a chemical released by the body’s allergy cells during an allergic reaction, these foods can trigger allergy-like responses when consumed during your allergy season. Jeffrey G. Demain, MD, who serves on the board of directors at the American Academy of Allergy Asthma and Immunology, says, “Sulfites and metabisulfites are a natural product of fermentation and can be added as preservatives—this is most commonly a problem associated with red wine and some beers.” Other products that can also trigger spring allergy symptoms include grains, yeasts, and contaminants. “Rarely, anaphylaxis has been reported,” he adds. If you find that sulfites trigger your allergies, then try a more distilled beverage. Otherwise, just say no to adult beverages till the season passes. Check out these 20 bizarre things you never knew you could be allergic to.
Fruit may be great for your health as a source of vitamins and minerals, but for oral allergy syndrome sufferers, all they cause is discomfort. Cross-reacting allergens found in pollen and raw fruits, vegetables, and some tree nuts can trigger symptoms of oral allergy syndrome (also known as pollen-food syndrome) because the immune system recognizes the pollen and similar proteins in the food and directs an allergic response to it. The biggest oral allergy triggers are fresh or dried fruits (such as nectarines, peaches, cherries, and apples) and vegetables, including celery, carrots, string beans, snap peas, and peppers, and even some nuts, like walnuts and almonds. Here are 11 more unusual things that make allergies worse.
