Anyone suffering with a food allergy knows that the condition is nothing to sneeze at. But this week, a new report commissioned by the federal government will be published stating that the majority of Americans who think they have food allergies actually do not.
According to The New York Times, 30% of Americans are under the impression that they have food allergies, yet the report found that the real number is much lower. “The true incidence of food allergies is only about 8 percent for children and less than 5 percent for adults,” the Times reports.
Now, the problem isn’t that Americans are hypochondriacs by nature (although that certainly is true with my family.) Rather, the issue is that testing for food allergies can be complicated and often inaccurate. Most doctors test for food allergies either by placing a small amount of food into the skin to see whether it produces some swelling or redness, or else they do a blood test to check for specific antibodies associated with these allergies. Yet, these tests are far from conclusive because our immune systems may be sensitive to certain foods even if we are not really allergic to them.
The National Institute of Allergy and Infectious Diseases is currently working on a new set of guidelines for allergy testing. For now, the best option is still to consult a doctor if you suspect you have an allergy. You may want to ask your physician to consider giving you a test known as a food challenge, where patients are exposed to potential allergens gradually over the course of several days. The test is considered more accurate but it’s used less often because it takes longer and is more intensive.
