Abstract
This is the first epidemiological report on the study of immediate type food allergy in Japan. We evaluated 1, 597 cases with the age range of 0 to 72 years. Egg/egg products appeared to be the most common food allergen. The second and third were found to be milk/milk products and wheat.
In our epidemiological study, even those with immediate-type reaction showed negative results in RAST, which suggests that one must still exercise case in eating food even when one is tested negative in RAST.
