To assess the nutritional quality of plant-based meat analogues in Australia, compared to equivalent products, and levels micronutrient fortification analogues.This cross-sectional study used nutrition composition data for products collected 2021 from major supermarkets Australia. Nutritional was assessed using Health Star Rating, energy (kJ), protein (g), saturated fat sodium (mg), total sugars fibre content (g) per 100 g, level food processing NOVA classification. Proportion fortified with...
Abstract Background Consumption of ultra-processed foods is associated with increased risk obesity and non-communicable diseases. Little known about current patterns intake in Australia. The aim this study was to examine the amount type purchased by Australian households 2019 determine whether purchases differed socio-economic status (SES). We also assessed changed between 2015 2019. Methods used grocery purchase data from a nationally representative consumer panel Australia assess packaged...
Greenhouse gas emissions (GHGe) data are predominantly available for agricultural commodities and broad dietary patterns. However, on commonly consumed, multi-ingredient food products as sold in supermarkets retail outlets mostly absent. We developed a novel approach to estimate product-specific GHGe individual packaged foods beverages marketed Australia 2019. Ingredient lists 23,550 were systematically disaggregated linear program was used ingredient proportions each product....
Abstract Switching between similar food and beverage products may reduce greenhouse gas emissions (GHGe). Here, using consumer data linked to 23,550 product-specific GHGe values, we estimated annual attributable product purchases consumed at home in Australia calculated reductions from specific switches. Potential changes mean Health Star Rating, energy density the proportion of ultraprocessed foods purchased were assessed. Approximately 31 million tonnes 2019, three highest contributors...
Abstract Aims The Australian Dietary Guidelines are currently being revised and ultra‐processed foods have been identified as a high priority action area. To better understand how well the current align with level of processing classifications, aim this study was to assess alignment between NOVA classification system for classifying healthiness packaged foods. Methods Data were sourced from FoodSwitch dataset, which included 28 071 food beverage products available in major supermarkets 2022....
Unhealthy diets are underpinned by the over-consumption of packaged products. Data describing ingredient composition these products is limited. We sought to define ingredients used in Australian foods and beverages assess associations between number existing health indicators. Statements were disaggregated, creating separate fields for each sub-ingredient. Ingredients categorised average per product was calculated. Associations both nutrient-based Health Star Rating (HSR) NOVA...
We investigated the extent of alignment between 'healthiness' defined by a food classification system that classifies foods and beverages primarily their nutrient composition, Health Star Rating (HSR) considers only degree processing product, NOVA system. used data for 25 486 products contained within George Institute Global Health's Australian 2022 FoodSwitch Dataset. Agreement two systems in proportion classified as 'healthier' (HSR ≥3.5 or group 1-3) 'less healthy' <3.5 4) was assessed...
Abstract Aim To modify the Australian and New Zealand Health Star Rating to account for ultra‐processing compare alignment of modified ratings with NOVA classifications current Dietary Guidelines core (recommended foods) discretionary (foods limit). Methods Data was cross‐sectionally analysed 25 486 products. Four approaches were compared original Rating: (1) five ‘negative’ points added ultra‐processed products ( modification 1; inclusion approach ); (2) restricted a maximum 3.0 Stars 2;...
Input-output tables for national economies are widely available and may provide an established mechanism estimating environmental impacts of industry sectors. We used environmentally extended input-output (EEIO) analysis to estimate greenhouse gas emissions (GHGe) Australian packaged foods beverages compared the findings those derived from life cycle (LCA). GHGe intensities in purchaser prices were alongside corresponding median per kilogram NielsenIQ Homescan, a nationally representative...
Input-output tables describing national economies are widely available and may provide a mechanism for estimating environmental impacts of industry sectors. We used these data to estimate greenhouse gas emissions (GHGe) Australian packaged foods beverages compared the findings those derived from approaches based on life cycle analysis (LCA). GHGe intensity (kg CO2eq per dollar) was environmentally extended input-output (EEIO) data, 2019 price-adjusted. Corresponding median prices kilogram...
