According to data made available by the Centers for Disease Control and Prevention (CDC), 5.7 percent of children in the United States displayed signs of a food allergy in the past year.
Moreover, a report published earlier this year in The Journal of Allergy and Clinical Immunology stated that almost 4 percent of U.S. adults are diagnosed with food allergies or intolerances.
But at what time in life are allergies most likely to develop? Many studies so far have focused on aspects determining the development of allergies in childhood, such as environmental factors and breast-feeding. Yet are allergies — especially food allergies — primarily relegated to the childhood years?
A new study led by Dr. Ruchi Gupta, director of Science and Outcomes of Allergy and Asthma Research at Northwestern University Feinberg School of Medicine and Ann and Robert H. Lurie Children’s Hospital of Chicago — both in Chicago, IL — suggests that almost half of U.S. adults with food allergies developed their condition in adulthood.
