Objective To describe the food environment in rural villages and an urban slum setting in India with reference to commercially available unbranded packaged snacks and street foods sold by vendors, and to analyze the type and quantity of fat in these foods. Design Cross-sectional. Setting Two low-income villages in Haryana and an urban slum in Delhi. Participants Street vendors (n = 44) were surveyed and the nutritional content of snacks (n = 49) sold by vendors was analyzed. Main Outcome Measures Vendors' awareness and perception of fats and oils, as well as the type of snacks sold, along with the content and quality of fat present in the snacks. Analysis Descriptive statistics of vendor survey and gas chromatography to measure fatty acid content in snacks. Results A variety of snacks were sold, including those in unlabeled transparent packages and open glass jars. Mean fat content in snacks was 28.8 g per 100-g serving in rural settings and 29.6 g per 100-g serving in urban settings. Sampled oils contained high levels of saturated fats (25% to 69% total fatty acids) and trans fats (0.1% to 30% of total fatty acids). Conclusions and Implications Interventions need to target the manufacturers of oils and fats used in freshly prepared products to improve the quality of foods available in the food environment of low-socioeconomic groups in India. © 2016 The Authors

Background: The consumption of partially hydrogenated vegetable oils (PHVOs) high in trans fat is associated with an increased risk of cardiovascular disease and other non-communicable diseases. In response to high intakes of PHVOs, the Indian government has proposed regulation to set limits on the amount of trans fat permissible in PHVOs. Global recommendations are to replace PHVOs with polyunsaturated fatty acids (PUFAs) in order to optimise health benefits; however, little is known about the practicalities of implementation in low-income settings. The aim of this study was to examine the technical and economic feasibility of reducing trans fat in PHVOs and reformulating it using healthier fats. Methods. Thirteen semi-structured interviews were conducted with manufacturers and technical experts of PHVOs in India. Data were open-coded and organised according to key themes. Results: Interviewees indicated that reformulating PHVOs was both economically and technically feasible provided that trans fat regulation takes account of the food technology challenges associated with product reformulation. However, there will be challenges in maintaining the physical properties that consumers prefer while reducing the trans fat in PHVOs. The availability of input oils was not seen to be a problem because of the low cost and high availability of imported palm oil, which was the input oil of choice for industry. Most interviewees were not concerned about the potential increase in saturated fat associated with increased use of palm oil and were not planning to use PUFAs in product reformulation. Interviewees indicated that many smaller manufacturers would not have sufficient capacity to reformulate products to reduce trans fat. Conclusions: Reformulating PHVOs to reduce trans fat in India is feasible; however, a collision course exists where the public health goal to replace PHVOs with PUFA are opposed to the goals of industry to produce a cheap alternative product that meets consumer preferences. Ensuring that product reformulation is done in a way that maximises health benefits will require shifts in knowledge and subsequent demand of products, decreased reliance on palm oil, investment in research and development and increased capacity for smaller manufacturers. © 2013 Downs et al.; licensee BioMed Central Ltd.
