Abstract

The rapid growth in the consumption of ultra-processed foods (UPFs) in India has emerged as a major public health concern, contributing significantly to the increasing burden of non-communicable diseases. Nutrition labels are intended to assist consumers in making informed dietary choices; however, their effectiveness in identifying UPFs remains questionable. This review examines the extent to which existing nutrition labeling practices influence consumer understanding and purchasing decisions in the Indian context. A systematic evidence synthesis of 15 Indian studies was conducted, incorporating findings from national surveys, randomized controlled trials, consumer behavior studies, eye-tracking experiments, and nutritional profiling of packaged food products. The review demonstrates that conventional back-of-pack nutrition labels receive minimal consumer attention during purchase decisions due to limited time, low nutrition literacy, technical terminology, and mathematical complexity. Furthermore, front-of-pack promotional claims frequently create a "health halo" effect, leading consumers to misjudge the nutritional quality of highly processed products. Evidence consistently indicates that non-compensatory front-of-pack warning labels, particularly black octagonal warning symbols, substantially improve consumers' ability to identify unhealthy foods while reducing cognitive burden across diverse educational and socioeconomic groups. The findings also highlight significant rural-urban disparities and linguistic barriers that limit the effectiveness of text-based labeling systems. The study concludes that India should adopt mandatory, simple, language-independent front-of-pack warning labels and strengthen transparency regarding food processing to enable healthier consumer choices and support national efforts to reduce diet-related diseases.
