A US survey has highlighted the growing influence of allergen information on where people choose to eat and suggests that clear allergen information can significantly shape food service customer loyalty.
The Nutritics 2026 Allergy Dining Report surveyed 1,000 Americans whose dining decisions are affected by food allergies. It found that uncertainty about allergens regularly changes the way diners make restaurant choices, with many abandoning restaurants before they ever make a booking.
Almost all respondents had decided against eating at a restaurant because allergen information was unclear or difficult to find. Many reported choosing a different venue, while others opted to eat at home rather than spend time trying to determine whether a meal would be safe. Importantly, the impact often extends beyond the individual with allergies, influencing decisions made by families, friends and work colleagues. The loss of income is estimated to be US $12.6 billion (an average of $78 per table) per year.
Clear allergen information was also found to be a powerful driver of trust and repeat visitation. More than two-thirds of respondents said they would dine out more often if restaurants provided clear, easily accessible allergen information, while many had recommended venues that demonstrated strong allergen practices. Diners reported the highest levels of confidence when allergens were clearly labelled on menu items, rather than relying solely on verbal information from staff.
The findings reinforce the importance of allergen transparency, suggesting that clear, consistent communication not only supports safer dining experiences but can also help build customer confidence, loyalty and advocacy.
