Knowledge, perception, and practical understanding of food labels: A cross-sectional study among Bangladeshi consumers

This research aimed to assess consumers' knowledge, perception, and practical understanding of food labels. A validated, structured questionnaire was employed for data collection. Data were collected from 1238 respondents covering all eight administrative divisions of Bangladesh using a nonrandomized convenience sampling method. Linear regression analyses were conducted to establish the relationship between demographic attributes and respondents' practical understanding of food labels. The majority of participants (52.5%) actively read food labels when purchasing a product for the first time. Food labels are regarded as "very important" by 56.2% of respondents and "important" by 35.7% of respondents. Label information is prioritized to highlight the importance of clear production and expiration dates (70%), followed by nutritional composition (56.7%) and source of raw material (52.5%). Despite this, over half of the participants demonstrated a limited practical understanding of the nutritional components on labels. The results of our linear regression analysis suggest that individuals within the age range of 18-28, belonging to Muslim communities, residing in the Dhaka and Khulna divisions, being higher educated, possessing a good understanding of nutrition, and being acquainted with the food safety agency of Bangladesh tend to exhibit a greater degree of practical knowledge regarding food labeling when compared to their counterparts. The study emphasizes the importance of clearer label information, particularly for nutritional value, and calls for targeted educational programs to improve consumer understanding of food labels, with a focus on older age groups and expanded educational efforts.
