Do you also have an allergy to sulfites? (Sulfite Sensitivity) Let's find out exactly about this
Have you ever wondered why you sometimes feel a strange discomfort after drinking a little wine, or eating something like canned food or dried fruit? Maybe you get a rash on your skin, or you feel a little difficult to breathe. This could be because you are sensitive to a chemical called 'Sulfite'. Don't worry, although this is not common for most people, it is very important to be aware of this. Let's talk about it simply today.

What exactly is sulfite?

Simply put, sulfites are a group of chemicals used to preserve certain foods and drinks, to keep them fresh and beautiful, and to prevent the growth of bacteria and fungi. They are most commonly used as preservatives. Think of it, dried apricots from the store have that beautiful orange color, or bottled lemon juice has the same color. But these are not always added to foods. Sometimes they are also formed naturally. For example, when making wine and beer, sulfites are naturally formed during the fermentation process. So, for most people, these sulfites do not cause any problems. But for a very small minority, especially people with medical conditions like asthma , they can have adverse effects on the body.

What are the symptoms of sulfite sensitivity?

If you have a sulfite sensitivity, you may experience a variety of symptoms within minutes to hours of eating or drinking something that contains sulfites. These symptoms vary from person to person. While some people may experience only mild discomfort, others may experience life-threatening symptoms.
Most importantly, people with asthma are more likely to have severe reactions to sulfites .
Let's see what these symptoms are.

Foods that may contain sulfites

Now you may be thinking, "Okay, so what should I be careful about when eating and drinking?" Below is a list of foods that may contain sulfites. But remember, not all of these things always contain sulfites. But it's important to read the label when buying these and ask when eating out at a restaurant.
  • Beverages: Wine (especially white wine), beer, apple cider, bottled lime and lemon juice, some fruit juices.
  • Dried fruits: Things like dried apricots, raisins, etc.
  • Canned and prepared vegetables and fruits: canned vegetables, pickles, jams, Maraschino cherries.
  • Potato-based products: Pre-cut, dried and prepared potatoes, potato chips.
  • Seafood: Frozen or fresh shrimp.
  • Other items: Baked goods, Soup mixes, some Gravies/Condiments, Guacamole.

How do you find sulfites on the label?

In Sri Lanka, we rarely read the ingredients list when we buy something from a supermarket. But if you have this kind of sensitivity, this habit is very important. "Sulfite" may not be directly written. Instead, look for chemical names like these.
The name that may appear on the label
Sulfur dioxide
Potassium bisulfite or potassium metabisulfite
Sodium bisulfite, sodium metabisulfite, or sodium sulfite

How to live with this situation?

If you suspect you have a sulfite sensitivity, the first and most important thing to do is to see your family doctor (physician). It is essential to get an accurate diagnosis and advice from a doctor, rather than guessing. He or she will ask you questions, ask you to keep a food diary if necessary, or refer you to a specialist. In addition, you can do the following:
  • Always read labels: Read the ingredients list on every packaged food and drink you buy from the store.
  • Ask when eating out: When you go to a restaurant or hotel, don't be afraid to ask if anything containing sulfites is added to your food. Asking, "I'm sensitive to sulfites, can you please check if this food contains them?" is very important for your safety.
  • Choose fresh foods: Instead of processed foods with preservatives, include fresh vegetables, fruits, meat, and fish in your diet as much as possible.

Take-Home Message

  • Sulfites are chemicals used to preserve food. Some people may be allergic to them.
  • Symptoms can range from something as minor as a skin rash to something as severe as difficulty breathing. People with asthma are at higher risk.
  • If you have any doubts about this, definitely see a doctor and seek advice.
  • Always read the 'Ingredients' list when buying something at the store. Ask about it when eating out.
