1.4.3 Legislative and fiscal measures

Legislative and fiscal measures are powerful tools to steer populations towards healthier dietary patterns.

Government policy and intervention

Governments have implemented policies such as sugar taxes, restrictions on unhealthy food advertising, and mandatory reformulation targets to reduce harmful ingredients in processed foods. For instance, the UK’s Soft Drinks Industry Levy, commonly referred to as the “sugar tax,” has led to substantial reductions in the sugar content of beverages and a corresponding decrease in sugar consumption, demonstrating the effectiveness of fiscal levers in driving industry and consumer behaviour. Similarly, Denmark’s tax on saturated fats, though later repealed, initially prompted food manufacturers to modify product formulations and raised public awareness of unhealthy fats. The success of these measures hinges on robust enforcement, ongoing evaluation, and integration with wider public health initiatives to ensure sustained improvements in dietary habits and health outcomes.

Private sector behavioural science approaches

Private sector companies have increasingly adopted behavioural science approaches to influence food pricing and consumer purchasing decisions. For example, retailers may use price promotions, loyalty schemes, and strategic placement of healthier items to nudge customers towards more nutritious choices. For example, the UK’s policy restricting promotions such as “buy one get one free” on foods high in fat, salt, or sugar, aims to reduce impulse purchasing and overconsumption of unhealthy products. By leveraging insights into consumer behaviour, such as the tendency to respond to price anchors or limited-time offers, companies can make healthier options appear more attractive and accessible, especially in comparison to less healthy alternatives.
