What do the Australian public think of regulatory nutrition policies? A scoping review.

Effective government policies are crucial to creating healthy food environments. However, changing public policy is a slow and challenging process involving many competing factors. One cited factor is public opinion towards a proposed policy. This study aimed to systematically explore public opinion on regulatory nutrition policy issues in Australia from 2009 to 2019, to determine whether low levels of public opinion corresponded with the low levels of regulatory policy action in this country. We found that there was varying levels of public support in Australia for public health nutrition action. Regulatory- and legislative-based policies generally had moderate to high levels of support except for food and drink taxes, which had low to moderate support. Despite high levels of public support for certain policy initiatives, national public health nutrition policy in Australia has not evolved consistently with the level of public support nor the evidence base over the past decade indicating other more important factors at play in policymaking.
