Nudging populations towards healthier eating behaviours: an innovative case study on salt reduction in China

Overview

To address the health challenges brought about by the changing food environment and high salt intake, WHO China, jointly with the National Institute for Nutrition and Health of China CDC and Tsinghua University, conducted an innovative study that applied nudge-based interventions to promote lower salt dish options on a Chinese meal delivery app in 2020-2022.

By documenting the key study findings, this case study aims to inspire key stakeholders in China and the Western Pacific Region on how behavioural insights can nudge consumers to choose healthier foods, build enabling food environments and improve the health and well-being of their people.
