To provide an overview of previous reviews of programs that aimed to improve nutritional status or diet-related health outcomes for Aboriginal and Torres Strait Islander peoples, in order to determine what programs are effective and why. A systematic search of databases and relevant websites was undertaken to identify reviews of nutrition interventions for Aboriginal and Torres Strait Islander Australians. Pairs of reviewers undertook study selection and data extraction and performed quality assessment using a validated tool. Twelve papers reporting 11 reviews were identified. Two reviews were rated high quality, three were rated medium and six were rated low quality. The reviews demonstrated that a positive effect on nutrition and chronic disease indicators can be a result of: 1) incorporating nutrition and breastfeeding advice into maternal and child health care services; and 2) multifaceted community nutrition programs. The evidence suggests that the most important factor determining the success of Aboriginal and Torres Strait Islander food and nutrition programs is community involvement in (and, ideally, control of) program development and implementation. Community-directed food and nutrition programs, especially those with multiple components that address the underlying causes of nutrition issues, can be effective in improving nutrition-related outcomes. More effective action is urgently required in order to reduce the unacceptable health inequalities between Aboriginal and Torres Strait Islander peoples and non-Indigenous Australians. Food insecurity and nutrition-related chronic conditions are responsible for a large proportion of the ill health experienced by Australia's First Peoples. This narrative overview of 11 reviews published between 2005 and 2015 provides a synthesis of the current evidence for improving Aboriginal and Torres Strait Islander nutrition across the lifespan. The findings suggest that community-based and community-controlled programs, especially those with multiple components that address the underlying causes of nutrition issues, have the greatest potential to improve nutrition-related health outcomes. Food and nutrition programs that are initiated and designed by local Aboriginal and Torres Strait Islander people are most likely to be effective. Nutrition and breastfeeding education and advice should be consistently incorporated into maternal and child healthcare services. Nutrition issues should be addressed through multifaceted approaches that address improving individual knowledge and skills, as well as strategies that increase access to nutritious food and provide a healthy food environment.

Results suggest the Aboriginal advertisement resonated with Aboriginal and Torres Strait Islander people and impacted knowledge about the sugar content of SSBs, particularly in Victoria where the campaign originated. SO WHAT?: This study highlights the importance of Aboriginal and Torres Strait Islander-led health promotion campaigns and tailoring health messages to the local Aboriginal and/or Torres Strait Islander community.

The coverage of Aboriginal and Torres Strait Islander nutrition in newspapers does not reflect the diversity and strengths of Australia's First Peoples. Implications for public health: This study highlights the role of the media in policy advocacy; however, advocates should ensure that they do not perpetuate negative representations of Aboriginal and Torres Strait Islander peoples.
