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 21 February 2018), providing an extensive overview of implemented government policy actions from around the world.

The evidence suggests people who want to eat well use nutrient lists to choose healthier options. Interpretative labels help them when they find the labels hard to understand. Nutrition labels also create incentives for food manufacturers to reformulate their products, so helping populations more broadly by increasing the availability of food of higher nutritional value.
Clear standards are also needed on the use of nutrient and health claims. Evidence shows these claims alter the perception people have of these products – making it essential that they do not mislead.

*Most other countries follow Guideline CAC/GL 2-1985 from the Codex Alimentarius Commission in requiring nutrition labels only when a nutrition or health claim is made and/or on food with special dietary uses
Producers and retailers are required by law to provide a list of the nutrient content of pre-packaged food products (with limited exceptions), even in the absence of a nutrition or health claim. The rules define which nutrients must be listed and on what basis (eg per 100g/per serving).

Nutrient lists on pre-packaged food must, by law, include the trans fat content of the food. The rules generally define how the trans fat content must be listed, and on what basis (eg per 100g/100ml or per serving). If the trans fat content falls below a certain threshold, it may be listed as 0g (eg less than 0.5g per serving, or less than 0.3g per 100g of food product). Chile requires mandatory trans fat labelling only once the total fat content per serving exceeds 3g.

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 2006, the government's Centre for Health Protection in Hong Kong issued guidelines for tuck shop operators in primary schools, as well as parents and school personnel, to guide the types of food and drink items to be allowed and promoted in the school environment for the benefit of children's health. They were revised to include secondary schools in 2010.
