The science behind the food warning labels: How Hyderabad researchers paved the way

Hyderabad-based National Institute of Nutrition research has highlighted the limitations of complex nutrition labels and the potential of visual warnings to help consumers identify unhealthy foods. Its dietary guidelines also provide nutrient limits relevant to front-of-pack labelling.

Hyderabad: While the FSSAI’s proposal to establish red warnings has received widespread nod, the foundational research on this field was laid by scientists from Hyderabad-based National Institute of Nutrition (NIN). Years ahead of the present new regulatory proposals, the NIN researchers focused on finding practical solutions to combat the rapid surge in obesity, diabetes, and cardiovascular disorders driven by the proliferation of ultra-processed commercial foods.

Through extensive consumer psychology studies and dietary evaluations, the institute established that everyday shoppers struggle to interpret complicated numerical nutrition charts or multi-tier star systems. The NIN findings revealed that explicit visual cues such as straightforward warning seals are significantly better than star ratings.

The institute’s updated Dietary Guidelines for Indians supplied the exact nutritional thresholds and cutoffs needed to make a mandate enforceable. By establishing right limits for sodium, added sugars, and saturated fats based on local dietary patterns, the NIN researchers provided regulators with the scientific justification needed to come-up a transparent labelling framework.
