Article
Full-text available
Background and aims The negative effect on dietary nutrient profiles is the most obvious mechanism explaining the higher risk of cardiometabolic diseases associated with increased dietary share of UPF observed in large cohort studies. We estimate the proportion of diets with excessive energy density, excessive free sugars or saturated fat contents...

Our dominant food system is a primary driver of worsening human and planetary health. Held in March 2022, the Public Health Association of Australia’s Food Futures Conference was an opportunity for people working across the food system to connect and advocate for a comprehensive, intersectoral, whole-of-society food and nutrition policy in Australi...

Background Policy makers are increasingly using nutrition classification schemes (NCSs) to assess a food's health potential for informing nutrition policy actions. However, there is wide variability among the NCSs implemented and no standard benchmark against which their contrasting assessments can be validated. Objective This study aimed to compa...

Article
Background: As evidence grows about negative health impacts of ultra-processed foods (UPFs), nutrient-centred advice is contested, and food-based dietary guidelines are increasingly utilised. Previous analyses of dietary guidelines evaluated their potential impact on health and sustainability, but little research has been conducted to examine how...

Article
Full-text available
Evolving evidence has shown that ultra-processed food (UPF) consumption may increase exposure to chemicals used in food packaging and production, such as per- and poly- fluoroalkyl substances, phthalates, and bisphenols. Studies have suggested that these contaminants may be transferred from mother to child across the placenta, increasing concerns f...

Cross-sectional nutritional survey data collected in eight countries were used to estimate saturated fatty acid intakes. Our objective was to estimate the proportion of excessive saturated fatty acid intakes (>10 % of total energy intake) that could be avoided if ultra-processed food consumption was reduced to levels observed in the first quintile...
Article
Full-text available
Background Rapid simultaneous increases in ultra-processed food sales and obesity prevalence have been observed worldwide, including in Australia. Consumption of ultra-processed foods by the Australian population was previously shown to be systematically associated with increased risk of intakes of nutrients outside levels recommended for the preve...

The inappropriate marketing and aggressive promotion of breastmilk substitutes (BMS) undermines breastfeeding and harms child and maternal health in all country contexts. Although a global milk formula 'sales boom' is reportedly underway, few studies have investigated its dynamics and determinants. This study takes two steps. First, it describes tr...
Article
Background Relevant evidence has addressed the negative impact of food processing on health. However, maternal ultra-processed food consumption is poorly investigated. Aim To analyze food consumption according to the degree of food processing, dietary diversity, and associated socio-demographic factors during pregnancy. Methods Cross-sectional da...

Objective To analyze the contribution of ultra-processed foods to the intake of free sugars among different age groups in Australia. Methods Dietary intakes of 12,153 participants from the National Nutrition and Physical Activity Survey (2011–12) aged 2+ years were evaluated. Food items collected through two 24-h recalls were classified according...

Understanding the drivers and dynamics of global ultra‐processed food (UPF) consumption is essential, given the evidence linking these foods with adverse health outcomes. In this synthesis review, we take two steps. First, we quantify per capita volumes and trends in UPF sales, and ingredients (sweeteners, fats, sodium and cosmetic additives) suppl...
Article

The nutrition literature and authoritative reports increasingly recognise the concept of ultra-processed foods (UPF), as a descriptor of unhealthy diets. UPFs are now prevalent in diets worldwide. This review aims to identify and appraise the studies on healthy participants that investigated associations between levels of UPF consumption and health...

Article
Ultra-processed foods are industrial formulations requiring little if any preparation before consumption. Their consumption is increasing in many countries and one of the possible determinants is the decrease in home cooking. As parents are key for family meals, we analysed the influence of parents' cooking skills confidence on children's consumpti...
