Evaluation of public health and economic impacts of dietary salt reduction initiatives on social security expenditures for cardiovascular disease control in Japan

Japan has undertaken extensive efforts to reduce dietary salt intake and prevent cardiovascular diseases. Although salt consumption has decreased over time, levels remain high, highlighting the need for continued promotion of low-salt food products through collaboration among government bodies, the food industry, academia, and other stakeholders. Effective policy development requires an environment that enables stakeholders to apply scientific evidence on the cost-effectiveness of salt reduction strategies. Our ongoing research focuses on developing simulation models to predict future public health and economic impacts, supporting the establishment of voluntary targets and evidence-based approaches. These strategies aim to lower salt intake, enhance health outcomes, and manage social security expenditures, thereby fostering sustainable development in an aging society.
