Online Food Delivery Applications and Their Impact on Dietary Practices of Working Professionals in Kochi, Kerala

The rapid growth of online food delivery applications (OFDAs) has significantly altered urban food environments and eating behaviours. Among working professionals, time constraints and convenience-oriented lifestyles may increase reliance on OFDAs, potentially affecting dietary quality and health outcomes. To assess the impact of online food delivery applications on dietary choices, usage patterns, and perceived health outcomes among working professionals in Kochi, Kerala. A cross-sectional study was conducted among 384 working professionals aged ≥18 years in Kochi, Kerala. Data were collected using a structured questionnaire covering sociodemographic characteristics, frequency and reasons for OFDA use, types of foods ordered, nutritional awareness, portion size variations, home-cooking practices, and perceived health outcomes. Descriptive statistics and correlation analyses were performed. Young adults aged 25-30 years and males constituted the predominant user group. Convenience and lack of time for home cooking were the primary determinants of OFDA usage. Fast foods and comfort foods were the most frequently ordered items, whereas healthier meal options were less commonly selected. Consideration of nutritional value prior to ordering was inconsistent. Frequent OFDA use was significantly associated with a preference for unhealthy foods, increased portion sizes, and perceived changes in body weight. However, no strong associations were observed with disruption of family meals or perceived sedentary behaviour. Online food delivery applications exert a notable influence on the dietary behaviours of working professionals, promoting convenience-driven food choices with potential long-term health consequences. Incorporation of nutrition-oriented features and supportive policy interventions within digital food platforms is essential to encourage healthier dietary practices.
