Food intolerances are commonly reported and are predicted to have gastrointestinal health implications. We aimed to quantify the prevalence of food intolerances among United States (US) adults and identify culprit foods through a brief web-based survey. We invited participation in an online cross-sectional survey involving a single questionnaire. Data were summarized using percentages or medians ± interquartile range (IQR). Participant characteristics by self-reported food intolerance were compared using the Wilcoxon rank sum test and Pearson’s chi-square test. Adjusted analyses were performed using multivariable logistic regression. The survey was internet-based via Amazon’s mechanical Turk, a crowdsourcing website for the completion of requester-directed tasks. Adults who were US-based internet users were invited ages 18–80. We collected 2133 survey responses (ages 18–79). The rate of food intolerance was 24.8% (95% CI, 23.0–26.6) in US adults. Younger (p<0.01), female (p=0.05), and Asian, African American, or multiple race individuals (p<0.01) predominated. Lactose intolerance was most common. Frequency of a non-lactose food intolerance was 18.1% (95% CI, 16.5–19.8). When categorized broadly, grains, fruit, lactose, fish, vegetables, alcohol, and nuts were most troublesome for individuals in that order. Self-reported food intolerance is common in US internet users. The effect of food on gastrointestinal symptoms and avoidant behaviors deserves further attention.
