According to Gizmodo, in a recent survey of 40,000 people, 19% of participants claimed they had a food allergy.
However, only half as many people reported the symptoms expected when eating a true allergen.
Such symptoms are hives, swelling of the lips or throat, and chest pain. Instead, they reported symptoms like stomach cramps, a stuffy nose, or nausea.
However, the latter symptoms indicate a food intolerance or sensitivity, rather than a true allergy.
