We developed the NOURISHING framework to highlight where governments need to take action to promote healthy diets and reduce overweight and obesity.
The framework is accompanied by a regularly updated database (last updated 8 May 2019), providing an extensive overview of implemented government policy actions from around the world.

We know from the evidence that making fruit and vegetables available in schools increases consumption. There is also evidence that food standards to restrict availability have the effect of reducing consumption of the restricted food.
For these actions to be effective for all children, they need to be sustained over time and accompanied by complementary behaviour change communication techniques, such as "modelling", school gardens, and communication to all stakeholders involved in the provision and consumption of school food. Worksites and healthcare also present strong potential for improved eating among adults.

In May 2017, the Trinidad and Tobago Ministry of Health introduced a ban on the sale or serving of sugar-sweetened drinks at all government and government-assisted schools. Banned sweetened drinks include soft drinks, juice drinks, flavoured water, sports/energy drinks, tea and coffee, and milk-based drinks with added sugars and artificial sweeteners. Only water, 100% juice, low-fat milk and blended vegetable or fruit drinks can be sold at schools. The changes were introduced in a phased approach and all cafeterias and canteens needed to be in full compliance by September 2017.
