How do peanut and nut-allergic consumers use information on the packaging to avoid allergens?

Area of Science:

• Food Science
• Consumer Behavior
• Allergy Research

Background:

• Recent legislation aims to enhance food allergy information on packaged foods.
• Understanding consumer risk assessment for food allergies is crucial.

Purpose of the Study:

• To investigate risk assessment decisions by adults with peanut and nut allergies during food purchasing.
• To explore the utilization of printed package information for allergy safety.

Main Methods:

• 32 participants' food shopping behavior and 'thinking aloud' were recorded.
• Semi-structured interviews and a 13-product task assessed purchasing decisions and reasoning.
• Analysis of transcribed data focused on the use of allergy advice boxes, ingredients lists, and other packaging information.

Main Results:

• Most participants relied on allergy advice boxes over ingredients lists for allergen checks.
• Package information was generally trusted, with brand and supermarket labels varying in reliability.
• Product images and names were used to infer potential nut presence, and 'nut-free' labeling was a desired improvement.

Conclusions:

• Food purchasing decisions for allergic consumers integrate label information with external factors like prior experience and manufacturer trust.
• Information not intended for allergen assessment, such as images and product names, influenced consumer choices.
• Enhanced labeling strategies, including clearer 'nut-free' claims, could improve food safety for allergic individuals.
