07 Jan 2019 --- At least one in ten US adults have food allergies, yet almost one in five believe that they actually have one, according to a cross-sectional study survey published in JAMA Network Open. The population-based survey study of 40,000 US adults sought to provide nationally representative estimates of the distribution, severity, and factors associated with adult food allergies. Based on the findings, the researchers highlight the importance of visiting a physician to determine a food allergy before eliminating foods from one’s diet, for example.
