The use of food processing terminology in Australian news media: a content analysis.

OBJECTIVE: This study aims to determine whether ultra-processed foods (UPFs) are being discussed in news media in Australia and whether this terminology, as described in the NOVA system, is being applied accurately. DESIGN: Interpretive content analysis of online and print media articles that mentioned UPFs from 2009 to 2023 in Australia. SETTING: Australia. PARTICIPANTS: Online and print media articles. RESULTS: A total of two hundred ninety-eight Australian media articles were captured. A substantial increase in the number of UPF articles was observed between 2017-2019 and 2021-2023. The UPF concept was inaccurately explained or defined in 32 % of the articles and was frequently used interchangeably with other descriptors, such as 'highly or heavily processed food', 'junk food', 'unhealthy food', 'packaged food' and 'discretionary food'. Most of the articles had a health focus; however, sustainability interest increased, particularly in the past 18 months. CONCLUSIONS: UPFs are increasingly being discussed in news media in Australia; however, the concept is still incorrectly presented in over a third of articles. This highlights the importance of improving the literacy about UPFs to ensure that messages are communicated in a way that is salient, accessible and accurate.

An analysis of the transformative potential of Australia's national food policies and policy actions to promote healthy and sustainable food systems.

OBJECTIVE: Despite commitment by many countries to promote food system transformation, Australia has yet to adopt a national food policy. This study aimed to evaluate Australian Federal Government's (AFG) food policies and policy actions potential to promote healthy and sustainable food systems. DESIGN: This study is a desk-based policy mapping followed by a theoretically guided evaluation of policy actions. This involved three steps: (1) identification of government departments and agencies that could influence Australia's food system; (2) identification of food policies and policy actions within these departments and (3) use of a conceptual framework to evaluate policy actions' potential of changing the food system as adjust (first-order change), reform (second-order change) or transform (third-order change). SETTING: Australia. PARTICIPANTS: None. RESULTS: Twenty-four food policies and sixty-two policy actions were identified across eight AFG departments and the Food Regulation System and evaluated based on the order of change they represented. Most policies were led by individual departments, reflecting the absence of a joined-up approach to food policy in Australia. Most policy actions (n 25/ 56·5 %) were evaluated as having adjust potential, whereas no transformative policy action was identified. CONCLUSIONS: These findings suggest that Australia is likely to proceed incrementally towards achieving food system change through adjustments and reforms but lacking transformative impact. To promote transformative change, all three orders of change must be strategically implemented in a coherent and coordinated matter. A comprehensive national food policy and a national coordinating body are needed to ensure a cohesive approach to policy.

Food consumption according to the degree of processing, dietary diversity and socio-demographic factors among pregnant women in Rio de Janeiro, Brazil: The Rio Birth Cohort Study of Environmental Exposure and Childhood Development (PIPA project).

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 data was taken from a birth cohort in Rio de Janeiro, Brazil, with 142 pregnant women. We assessed diet using a qualitative food frequency questionnaire and classified food items according to the NOVA classification system as non-ultra-processed-foods and ultra-processed-foods. Non-ultra-processed-food and ultra-processed-food scores were calculated, reflecting weekly intake of more than one subgroup. Dietary diversity of the non-ultra-processed-food diet fraction was described according to the Food and Agriculture Organization guidelines. The association between food consumption and socio-demographic factors were investigated using logistic regression models. RESULTS: Over 60% of the pregnant women reported consumption of at least three non-ultra-processed-food groups. However, only 25% had adequate dietary diversity. The level of education (Complete high school: odds ratio, 5.36; 95% confidence interval, 1.73-16.65) was associated with regular intake of "meat and eggs." Among the ultra-processed-food score, 27% of the participants described a weekly consumption of at least two ultra-processed-food subgroups. White women (odds ratio, 2.63; 95% confidence interval, 1.05-6.63) had a higher chance of reporting "packaged ready meals" consumption. CONCLUSIONS: This study shows a high weekly consumption of ultra-processed-food subgroups and low dietary diversity of the non-ultra-processed-food fraction of the diet of pregnant women in Brazil. Our results elucidate the influence of socio-demographic characteristics on diet quality during pregnancy.

Ultra-processed food consumption drives excessive free sugar intake among all age groups in Australia.

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 to the NOVA system. The contribution of each NOVA food group and their subgroups to total energy intake was determined by age group. Mean free sugar content in diet fractions made up exclusively of ultra-processed foods, or of processed foods, or of a combination of un/minimally processed foods and culinary ingredients (which includes table sugar and honey) were compared. Across quintiles of the energy contribution of ultra-processed foods, differences in the intake of free sugars, as well as in the prevalence of excessive free sugar intake (≥ 10% of total energy) were examined. RESULTS: Ultra-processed foods had the highest energy contribution among children, adolescents and adults in Australia, with older children and adolescents the highest consumers (53.1% and 54.3% of total energy, respectively). The diet fraction restricted to ultra-processed items contained significantly more free sugars than the two other diet fractions. Among all age groups, a positive and statistically significant linear association was found between quintiles of ultra-processed food consumption and both the average intake of free sugars and the prevalence of excessive free sugar intake. CONCLUSION: Ultra-processed food consumption drives excessive free sugar intake among all age groups in Australia.

Parents' cooking skills confidence reduce children's consumption of ultra-processed foods.

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 consumption of ultra-processed foods at dinner. This is a cross-sectional study with 657 child-parent pairs from nine private schools in São Paulo, Brazil. Food consumption data were collected using two children's dinner dietary recalls while the Cooking Skills Index was used to collect parents' cooking skills, measuring their confidence in their own skills related to cooking 'from scratch', according to the Dietary Guidelines for the Brazilian Population. Food items were classified according to the NOVA classification system, considering the nature, extension and purpose of food processing. We used linear regression models to test associations between parents' cooking skills confidence and the contribution of ultra-processed foods to total energy intake at dinner, adjusting for socio-demographic variables. Parents' mean age was 38.3 and children's mean age was 7.8. These parents were mostly women, white, married, employed, with full secondary education and per capita household incomes up to ~ USD 320.00/month. They reached an average of 78.8 points (SD 14.8) in the Cooking Skills Index. Children's mean energy intake at dinner was 672.2 kcal (31.3% from ultra-processed foods). The increase in parents' cooking skills confidence was directly associated with decrease in consumption of ultra-processed foods (ß = -0.17; p = 0.007), which remained after adjustment (ß = -0.15; p = 0.026). These findings suggest that parents' cooking skills confidence potentially protect their children against ultra-processed foods, indicating the need for revaluing cooking to promote healthy eating.

Consumption of ultra-processed foods decreases the quality of the overall diet of middle-aged Japanese adults.

OBJECTIVE: To estimate the consumption of ultra-processed foods and determine its association with dietary quality among middle-aged Japanese adults. DESIGN: Cross-sectional study using data from the Saitama Prefecture Health and Nutrition Survey 2011. Dietary intake was assessed using one- or two-day dietary records. Sociodemographic and lifestyle factors were obtained via self-administered questionnaire. Food items were classified according to the NOVA system into four groups: unprocessed or minimally processed foods; processed culinary ingredients; processed foods; and ultra-processed foods. The dietary share of each NOVA food group and their subgroups was calculated in relation to total energy intake, and the average dietary content of key nutrients was determined across tertiles of the dietary energy share of ultra-processed foods (low, middle and high intake). SETTING: Saitama Prefecture in Japan. PARTICIPANTS: Community-dwelling adults aged 30-59 years (256 men, 361 women). RESULTS: Consumption of unprocessed or minimally processed foods, processed culinary ingredients, processed foods and ultra-processed foods contributed 44·9 (se 0·8) %, 5·5 (se 0·2) %, 11·3 (se 0·4) % and 38·2 (se 0·9) % of total daily energy intake, respectively. A positive and statistically significant linear trend was found between the dietary share of ultra-processed foods (tertiles) and the dietary content of total and saturated fat, while an inverse relationship was observed for protein, vitamin K, vitamin B6, dietary fibre, magnesium, phosphorus and iron. CONCLUSIONS: Our findings show that higher consumption of ultra-processed foods was associated with decreased dietary quality among Japanese adults.

Association between watching TV whilst eating and children's consumption of ultraprocessed foods in United Kingdom.

This study aimed to assess the association between watching TV whilst eating and consumption of ultraprocessed foods amongst children aged 4-10 years old in the United Kingdom. Cross-sectional data from the UK National Diet and Nutrition Survey (NDNS 2008-2012) were analysed. Dietary data were derived from 4-day food diaries of 1,277 children, and the dietary contribution of ultraprocessed foods was assessed. Meals were classified based on time of day in which foods were consumed (lunch: 11 pm-3 pm and dinner: 6 pm-9 pm). Crude and adjusted linear regression models were employed to verify the effect of watching TV during meals on dietary contribution of ultraprocessed foods (% of total energy intake). More than 70% of the children watched TV during meals, and 31.4% presented the behaviour on both "lunch and dinner." Children's mean total energy intake was 1,532.3 kcal/day, of which 65.8% came from ultraprocessed foods. Findings indicated that children who watched TV whilst having both meals (lunch and dinner) consumed on average 85.5 kcal/day and 6.1% more energy from ultraprocessed foods than those who did not. Children who watched TV only during dinner consumed on average 37.1 kcal/day and 3.4% more energy from ultraprocessed foods than those who did not. The behaviour of watching TV whilst eating meals was associated with higher total daily consumption of ultraprocessed foods by children in the United Kingdom. Therefore, interventions designed to promote healthy eating habits should include aspects related to the context of meals.

Is food store type associated with the consumption of ultra-processed food and drink products in Brazil?

OBJECTIVE: To analyse the association between food store type and the consumption of ultra-processed products in Brazil. DESIGN: Data from the 2008-2009 Household Budget Survey involving a probabilistic sample of 55 970 Brazilian households. Food stores were grouped into nine categories. Foods and drinks were grouped according to characteristics of food processing. The contribution of each food store type to the total energy acquired from each food processing group, and according to quintiles of consumption of ultra-processed products, was estimated. Exploratory factor analysis was conducted to identify a pattern of food store usage. Linear regression models were performed to estimate the relationship between the purchase pattern and the consumption of ultra-processed products. RESULTS: In line with their larger market share, supermarkets accounted for 59 % of total energy and participated most in acquisition for three food groups, with emphasis on ultra-processed products (60·4 % of energy). The participation of supermarkets in total purchase tended to increase in populations with higher consumption of ultra-processed products, while the participation of small markets and small producers tended to decrease. The purchase pattern characterized by use of traditional retail (street fairs and vendors, small markets, small farmers, butcheries) was associated with a smaller consumption of ultra-processed products. CONCLUSIONS: Food policies and interventions aiming to reduce the consumption of ultra-processed products should consider the influence of supermarkets on the consumption of these products. A purchase pattern based on traditional retail constitutes an important tool for promoting healthy eating in Brazil.

Price and convenience: The influence of supermarkets on consumption of ultra-processed foods and beverages in Brazil.

OBJECTIVE: To evaluate the influence of convenience and price of ultra-processed foods and beverages on purchases at supermarkets. METHODS: The study used data on food and beverage acquisition for household consumption from the Brazilian Household Budget Survey, performed in a random sample of 55,970 households between 2008 and 2009. Foods and beverages were categorized into four groups, according to characteristics of food processing. Retail stores were grouped into supermarkets and other food stores. Proportion of calories from foods and beverages purchased at supermarkets and other food stores, and respective mean prices (R$/1000 kcal), were calculated according to households' geographical and socioeconomic characteristics. Effect of convenience in household purchases at retail stores was expressed by the acquisition of several food items at the same store. The influence of convenience and prices of ultra-processed products on purchases at supermarkets was analyzed using log-log regression model with estimation of elasticity coefficients. RESULTS: The mean prices of foods and beverages purchased at supermarkets were 37% lower in comparison to other food stores. The share of ultra-processed foods and beverages in purchases made at supermarkets was 25% higher than at other food stores. An increase of 1% in prices of ultra-processed food items led to a 0.59% reduction in calorie acquisition at supermarkets (R2 = 0.75; p < 0.001). On the other hand, an increase of 1% in the number of food items purchased at supermarkets resulted in 1.83% increase in calorie acquisition of ultra-processed foods and beverages (p < 0.001). CONCLUSION: Convenience and lower relative prices of food items purchased at supermarkets, in comparison to other food stores, are relevant to explain higher share of purchases of ultra-processed foods and beverages at supermarkets.

Ultra-processed food intake and diet carbon and water footprints: a national study in Brazil.

OBJECTIVE: To study the association between ultra-processed food consumption and carbon and water footprints of the Brazilian diet. METHODS: Cross-sectional analysis on data collected in 2008-2009 on a probabilistic sample of the Brazilian population aged ≥ 10 years (n = 32,886). Individual food intake was assessed using two 24-hour food records, on non-consecutive days. The environmental impact of individual diets was calculated by multiplying the amount of each food by coefficients that quantify the atmospheric emissions of greenhouse gases in grams of carbon dioxide equivalent (carbon footprint) and freshwater use in liters (water footprint), both per gram or milliliter of food. The two coefficients consider the food life cycle 'from farm to fork.' Crude and adjusted linear regression models and tests for linear trends assessed the association between the ultra-processed food contribution to total energy intake (quintiles) and the diet carbon and water footprints. Potential confounders included age, sex, education, income, and region. Total energy intake was assessed as a potential mediation variable. RESULTS: In the crude models, the dietary contribution of ultra-processed foods was linearly associated with the carbon and water footprints of the Brazilian diet. After adjustment for potential confounders, the association remained significant only regarding the diet water footprint, which increased by 10.1% between the lowest and highest quintile of the contribution of ultra-processed foods. Additional adjustment for total energy intake eliminated this association indicating that the dietary contribution of ultra-processed foods increases the diet water footprint by increasing energy intake. CONCLUSIONS: The negative impact of ultra-processed foods on the diet water footprint, shown for the first time in this study, adds to the negative impacts of these foods, already demonstrated regarding dietary nutrient profiles and the risk for several chronic non-communicable diseases. This reinforces the recommendation to avoid ultra-processed foods made in the official Brazilian Dietary Guidelines and increasingly in dietary guidelines of other countries.
