About one in 10 adults in the US have a food allergy.
But about one in five think they have one.
According to a new study, almost half of allergies adults think they have aren’t real.
Rather, many may have food intolerances or other food-related conditions.
Nearly half of respondents with severe allergies developed them as adults, according to the results.
About one in 10 adults in the US have a food allergy, according to a new study published in the journal JAMA Network Open — but nearly double that amount think they suffer with one despite the fact their symptoms are not consistent with a true allergy.
Scientists from Ann & Robert H. Lurie Children’s Hospital of Chicago and Northwestern University looked at data from a survey of 40,000 adults. Out of those surveyed, 10.8% reported severe allergy symptoms like a tightening throat and anaphylactic shock, and another 8.2% said they believed they had allergies, without those symptoms.
“While we found that one in 10 adults have [a] food allergy, nearly twice as many adults think that they are allergic to foods, while their symptoms may suggest food intolerance or other food related conditions,” said Ruchi Gupta, a doctor from Lurie Children’s and lead author of the study.
“It is important to see a physician for appropriate testing and diagnosis before completely eliminating foods from the diet. If food allergy is confirmed, understanding the management is also critical, including recognizing symptoms of anaphylaxis and how and when to use epinephrine.”
Just half of those with a severe allergy had a physician-confirmed diagnosis, the results suggested, and less than a quarter said they had a prescription of epinephrine — or an “EpiPen” that usually relieves the symptoms of an allergic reaction.
The most common food allergies among US adults are shellfish (affecting 7.2 million adults), milk (4.7 million), peanuts (4.5 million), tree nuts (3 million), fish (2.2 million), eggs (2 million), wheat (2 million), soy (1.5 million), and sesame (0.5 million).
The team were surprised to find that nearly half of allergic respondents developed at least one of their food allergies as an adult.
“More research is needed to understand why this is occurring and how we might prevent it,” said Gupta.
Gideon Lack, a professor of paediatric allergy at King’s College London, told The Guardian there has been a rise in children developing food allergies in recent years.
“We have been focusing efforts and concerns about …read more
