IFIC焦点调查：美国人对食物过敏原、不耐受性和敏感性的看法

April 2025 METHODOLOGY The International Food Information Council (IFIC) commissioned an online survey among U.S.consumers to measure knowledge, attitudes, and beliefs about food allergens, intolerances,and sensitivities. One thousand adults ages 18 years and older completed the online surveyfrom January 18-22, 2025, and were weighted toensure proportional results.Totals may notequal 100% due to rounding. The Bayesian confidencelevel for the survey sample (n=1000) is 3.5, whichisroughly equivalentto a margin of error of±3.1 at the95%confidence level.Callouts of statistically significant resultsare included where appropriate on slides displaying results.Something is statisticallysignificant if the result cannot beattributed to random chance. Statistical significance inthisreport is only compared within each demographicgroup (e.g. age, race, gender, etc.). SUGGESTED CITATION:International Food Information Council (IFIC). IFIC Spotlight Survey: Americans' Perceptions of Food Allergens, Intolerances& Sensitivities. April 2025. EXECUTIVE SUMMARY Food allergies, intolerances, and sensitivities affect millions of Americans andprevalence ofthese conditions ison the rise in recent decades. According to the Centersfor Disease Controland Prevention (CDC),6.2%of adults and5.8%of children in the U.S.have adiagnosed foodallergy.Other research has estimated5.1%of U.S. adults have a physician-confirmed foodallergy diagnosis, with total food allergy prevalence possibly exceeding10.8%.The prevalence offood intolerance is more difficult to measure. In a 2021online survey of more than 2,000American adults, one-quarter (24.8%) reported having a food intolerance. Food sensitivities areeven more challenging to measure, as there currently is no standard definition for a foodsensitivity. Many American households are impactedby adverse reactions tofoods and beverages. In thisIFIC Spotlight Survey, 24% of Americans reported that they or someone in their household havea food allergy, food intolerance, and/or food sensitivity.Nuts were the most common allergyreported, while dairy was the top intolerance and sensitivity.Among the 76% of survey takerswho reported that neither they nor someone in their household have a food allergy,intolerance, and/or sensitivity, nearly 4 in 10(38%) know someone outside their householdwhodoes.In total, more than half of Americans (53%) in this survey either have someone in theirhousehold (including themselves) or know someone outside of their home who is affected by afood allergy, intolerance, and/or sensitivity. When asked for their top three trusted sources for information on food allergens, intolerances,and sensitivities, primary care providers (68%), board-certified allergists (63%), and registereddietitians (56%) were selected most often.The top related concerns were “someone having areaction to food that you prepared” (1%), “accidental exposure in public settings” (1%),“unclear labeling information on packaged foods and beverages” (13%), and “eating away fromhome at a restaurant” (1 %). Survey takers were also asked about their history ofreceiving medical attention because of areaction to a food or beverage. One in seven Americans (16%) said they or someone in theirhousehold have received medical attention due to a reaction to food or beverage. Theremaining 84% said neither they nor anyone in their household have experienced this. With a growing number ofAmericansaffected byfood allergies, IFIC commissioned thisIFICSpotlight Survey: Americans’ Perceptions of Food Allergens, Intolerances & Sensitivitiestocapture current consumer perspectives.

K E Y F I N D I N G S Unclear labeling is a top concern among thosewho know someone (including themselves) with afood allergy, intolerance, and/or sensitivity. More than half of Americans say that either theyor someone in their household have a food allergy,intolerance, and/or sensitivity—or that they knowsomeone outside their household who does. Survey takerswho say theyeitherhave someone in their household(including themselves) or know someone outside of their home whois affected by an allergy, intolerance, and/or sensitivity to food,wereasked to rank their top three concerns from a list of potential food-related issues. Forty-two percent (%) selected “unclear labelinginformation on packaged foods and beverages” in their top three,making it the highest concern overall. The concerns most frequentlyranked first were: “someone having a reaction to food that youprepared” (1%), “accidental exposure in public settings” (1%),“unclear labeling information on packaged foods and beverages”(13%), and “eating away from home at a restaurant” (1 %). Nearly 1 in 4 (24%) survey takers report that they or someone in theirhousehold have a food allergy, food intolerance, and/or foodsensitivity. Among the 76% of survey takers who report that neitherth
