Differences between the normal and perceived appropriate portion sizes of discretionary foods.

Background: There are limited data on the amount of discretionary foods that people normally consume and consider as appropriate at one eating occasion. This study aimed to provide an overview of the range and assess differences of the 'normal portion size' and 'perceived appropriate portion size' of energy-dense nutrient-poor discretionary foods among consumers aged 18-65 years.

Methods: To measure normal and perceived appropriate portion sizes, a validated online image-series questionnaire consisting of eight successive portion size options for 15 discretionary foods was completed at two timepoints.

From preschool to policy: A scoping review of recommended interventions for a systems approach to improve dietary intake in early childhood.

Early childhood is a key opportunity to establish healthy eating behaviors and prevent future non-communicable diseases associated with poor diets. How to effectively intervene in the system of the many determinants influencing children's dietary intake remains unclear. This scoping review aimed to map the determinants of nutrition and eating that have been addressed in early childhood nutrition interventions and identify which of these improve dietary intake.

Offline to online: a systematic mapping review of evidence to inform nutrition-related policies applicable to online food delivery platforms.

Background: Online food delivery (OFD) platforms offer easy access to an abundance of energy-dense and nutrient-poor takeaway foods and may exacerbate existing unhealthy food environments. Efforts to improve population diets include a range of policy recommendations focused on improving the healthiness of food environments; however, the way in which such policies may apply to OFD platforms is not clear. This paper aimed to synthesise the existing evidence to inform nutrition-related policies applicable to OFD platforms for population health and well-being.

Portion Size Norms of Discretionary Foods and Eating Settings: A Repeated Cross-Sectional Study.

Background: The increase in serving sizes of energy-dense nutrient-poor discretionary foods over time, with attractively presented large servings and package sizes, has led to portion distortion and a new 'normal' for serving sizes. Little data exists on the variations of portion size norms of discretionary foods across settings. This study aimed to examine the differences in the range of normal portion sizes of commonly consumed foods between home and out-of-home settings (coffee shops, restaurants).

Evaluation of the Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP) for People Living With Cognitive Impairment and Dementia in Care Homes.

Background: Major knowledge and practice gaps exist in aged care home services to support independence of older people with dementia. This research evaluates an adaptation of a community-based rehabilitation model for care homes, namely Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP), by examining whether (and, if so, how) I-CHARP produces its intended effects and how this programme can be practicably implemented, sustained and scaled up across care homes in Australia.

Methods: I-CHARP is a 4-month bio-behavioural-environmental rehabilitation model of care, integrated in care home services, supported through the deployment of an implementation strategy, the Research Enabled Aged Care Homes (REACH) network.
