It’s pretty common to have a reaction to a certain food, but in most cases it’s an intolerance rather than a true allergy. Why does it matter? Although they may have similar symptoms, a food allergy can be more serious.
These clues can help you figure out if it is an allergy or intolerance. A doctor can help you know for sure.
The most common food intolerance is lactose intolerance. It happens when people can’t digest lactose, a sugar found in milk and dairy. Another kind of intolerance is being sensitive to sulfites or other food additives. Sulfites can trigger asthma attacks in some people.
What about a gluten allergy? While celiac disease -- a long-lasting digestive condition that’s triggered by eating gluten -- does involve the immune system, it doesn’t cause life-threatening symptoms.
