Sulfites

If you suffer from asthma or severe allergies, you might also be sensitive to sulfites, although (less commonly) people who don't have asthma can sometimes develop sensitivity. Sulfites are naturally-occurring chemicals found in foods and our bodies. They're generally used as preservatives in food, drinks and some medications. You might also have heard of sulfites in wines, which have been used in their production for centuries. 

Common symptoms include:

• wheezing
• coughing
• congestion
• diarrhea
• hives
• skin swelling
• skin blushing
• low blood pressure

The best way to know if you're sensitive to sulfites is to monitor your bodily reactions after consuming foods, drinks or medications that contain sulfites. If your doctor determines you have a sensitivity—or worse, an allergy—, you'll need to either avoid or eliminate sulfites from your diet. That means being especially vigilant when going out to eat, as you can't always check the ingredients you're consuming.
