However, public information campaigns may work best when implemented in synergy with other measures, such as increased availability or improved labelling (EATWELL, 2012). Moreover, successfully boosting changes in consumer habits regarding diets and food preparation would be difficult, unless efforts to make this change are linked to achieving national health objectives. For example, establishing financial incentives or taxes that discourage people from eating foods with high levels of animal fat could be part of national efforts to reduce heart disease and obesity. Nutrition and eco-labelling aim to inform consumers about the composition of foods and enable them to make informed choices about what they eat, it is a necessary condition for overcoming informational market failures, but does not overcome externality or public good issues associated with food consumption.
