Consumption, sources, and perceptions of unhealthy foods Among adults and adolescents in rural South Asia
Objectives: South Asian nations are experiencing a nutritional shift, transitioning from traditional diets to more energy-dense and processed alternatives containing added sugars, high salt, and saturated or trans fats, commonly known as unhealthy foods. This study examined unhealthy food consumption patterns, sources of acquisition, perceptions, and information sources among adults and adolescents in rural South Asia.
Methods: The Transforming Agrifood Systems in South Asia survey was conducted in 2023 across five rural districts (Bangladesh: Rangpur and Rajshahi; Nepal: Banke and Surkhet; India: Nalanda). In each district, 25 villages/wards and 4,000 households were selected (n=6,007 adults and n=3,995 adolescents). Dietary intake was assessed using 24-hour dietary recall via the Global Diet Quality Score application and a 7-day food frequency questionnaire. Information on eating occasions, purchasing habits, perceptions, and exposure to food advertisements was also collected.
Results: Among all unhealthy foods, sweets and ice cream had the highest daily consumption, ranging from 42-75% among respondents based on respondent type and district. Compared to India and Nepal, daily consumption of processed meat was 10-15 times higher in Bangladesh. Bangladeshi males consumed twice as much unhealthy food in the afternoon per day than other countries. Over the last 7 days, 38% adults and 22% adolescents consumed tea/coffee with sugar daily. Biscuits were perceived as safer and more nutritious compared to other unhealthy foods in Bangladesh (70%) and India (60%) than in Nepal (37%). Most unhealthy foods were purchased from large open-air markets in Bangladesh (60%) or small retail shops in Nepal (85%) and India (78%). Adolescents (47%) were more exposed to unhealthy food advertisements than adults (33%) in the past month, especially for soft drinks. However, adolescents (26%) also received more information on avoiding unhealthy foods than adults (14%), mostly from family/friends (44%) and schools (42%).
Conclusions: In South Asia, adults and adolescents consume a notable portion of their diets from unhealthy foods, with easy access and extensive exposure to unhealthy food advertisements. Further research on how lived experiences of the food environment impact the demand and consumption of unhealthy foods is needed.
