Ultra-processed foods (UPF), per the NOVA Classification, provide a major source of calories within modern food systems and are associated with poor health outcomes related to chronic inflammation. Dietary antioxidants play a key role in preventing disease, however, the relationship between the NOVA Classification and the total antioxidant content (TAC) of foods is not well-characterized. We hypothesized that TAC would be highest in Minimally Processed (MPF), lower in Processed (PRF), and lowest in UPF. TAC data for 3,137 animal-based, mixed, and plant-based food items were obtained from a published data set. After data cleaning, 1,946 food items and their TAC values were analyzed using two hierarchal linear models (alpha: p<0.05). MPF had the highest mean TAC (10.79 ± 0.87 mmol/100g) and were 11.31-fold and 10.72-fold higher than PRF and UPF, respectively (p=0.023). Plant-based and Mixed foods had a higher mean TAC (8.55 ± 0.68 and 1.12 ± 0.11 mmol/100g, respectively) and were 22.67-fold and 2.98-fold higher compared to animal-based foods (p<0.001). Food processing did not change mean TAC in Mixed and Animal-based foods; however, plant-based MPF had a higher mean TAC (11.49 ± 0.93 mmol/100g) and were 9.88-fold and 15.12-fold higher compared to plant-based PRF and UPF, respectively (p<0.001). Mean TAC differed between NOVA processing groups for three categories of food: Vegetables, Beverages, and Beans, Nuts & Seeds (p<0.001). Across all food items, and especially plant-based foods, mean TAC decreased with food processing. The lower TAC of UPFs may at least partially explain why their consumption promotes inflammatory chronic disease.

The aim of this study was to investigate the association between screen time and ultra-processed food consumption (UPF) across the lifespan. Data from the 2019 Brazilian National Health Survey, a cross-sectional and population-based study, was used. UPF consumption was evaluated using a score, calculated by summing the positive answers to questions about the consumption of 10 UPF subgroups on previous day. Scores ≥5 represented high UPF consumption. Daily time spent engaging with television or other screens was self-reported. Crude and adjusted models were obtained through Poisson regression and results were expressed in prevalence ratios by age group. The sample included 2,315 adolescents, 65,803 adults, and 22,728 older adults. Prevalence of UPF scores ≥5 was higher according to increased screen time, with dose-response across all age groups and types of screen time. Adolescents, adults, and older adults watching TV for ≥6 hours/day presented prevalence of UPF scores ≥5 1.8 (95% CI 1.2-2.9), 1.9 (95% CI 1.6-2.3) and 2.2 (95% CI 1.4-3.6) times higher, respectively, compared to those who did not watch TV. For other screens, prevalence of UPF scores ≥5 was 2.4 (95% CI 1.3-4.1) and 1.6 (95% CI 1.4-1.9) times higher for adolescents and adults using screens for ≥6 hours/day, respectively, while for older adults only screen times of 2-<3 and 3-<6 hours were significantly associated with UPF scores ≥5. Screen time was associated with high consumption of UPF in all age groups. Considering these associations when planning and implementing interventions would be beneficial for public health across the lifespan.

This article aims to evaluate the sociodemographic determinants of ultra-processed foods (UPF) consumption in the Brazilian population ≥ 10 years of age. The study used data from the personal and resident food consumption module of the Family Budget Surveys, grouping foods according to the NOVA classification of food processing. The classification and regression tree (CART) was used to identify the factors determining the lowest to highest percentage participation of UPF in the Brazilian population. UPF accounted for 37·0 % of energy content in 2017–2018. In the end, eight nodes of UPF consumption were identified, with household situation, education in years, age in years and per capita family income being the determining factors identified in the CART. The lowest consumption of UPF occurred among individuals living in rural areas with less than 4 years of education (23·78 %), while the highest consumption occurred among individuals living in urban areas, < 30 years of age and with per capita income ≥ US$257 (46·27 %). The determining factors identified in CART expose the diverse pattern of UPF consumption in the Brazilian population, especially conditions directly associated with access to these products, such as penetration in urban/rural regions. Through the results of this study, it may be possible to identify focal points for action in policies and actions to mitigate UPF consumption.

The present study investigated the relationships between maternal characteristics and subjective well-being (life satisfaction and optimism) among overweight Brazilian adult pregnant women. A cross-sectional study utilising baseline data from a randomised controlled clinical trial was conducted. A total of 330 women were investigated. Maternal characteristics (sociodemographic, obstetric and lifestyle) were obtained through a structured questionnaire. Data on dietary intake were collected through two 24-h dietary recalls, and the usual diet was estimated using the Multiple Source Method. Life satisfaction and optimism were assessed using validated instruments. Both unadjusted and adjusted linear regression models were employed to investigate the relationship between maternal characteristics and subjective well-being. Sleep quality was found to be positively associated with life satisfaction. Miscarriage and smoking during pregnancy were negatively associated with this sentiment. Additionally, a positive association was observed between optimism and maternal characteristics such as sleep quality, desired pregnancy and alcohol consumption in the previous 30 d. Furthermore, it was found that the consumption of sugary drinks, dietary fibre and Ca were positively associated with this same feeling. The present study showed that some maternal and food consumption characteristics were associated with subjective well-being among overweight pregnant women. It is, therefore, essential to recognise predictors of maternal mental health given their relevance to the field of public health.

Availability of ultra-processed foods is likely to be high in the Pacific(1) however, information on consumption is limited. This study aimed to assess consumption levels and dietary sources of ultra-processed foods (UPFs) in a population of adults in the Central Division of Fiji. A random sample of 700 adults was selected from two statistical enumeration areas (one semi-urban, one rural) in Fiji. Participant characteristics were collected, along with a three-pass 24-hour diet recall. Foods consumed were coded based on level of processing, in alignment with the NOVA categorisation system (1 = unprocessed, 2 = minimally processed,3 = processed and 4 = ultra-processed). UPF contribution to total energy, salt, fat, and sugar intake were estimated. Main sources of UPFs were then estimated by food group. 534 adults participated (76% response rate, 50% female). Preliminary results suggest that UPFs contributed 21.5% (%95 CI, 19.5% to 23.4%) of total energy intake. Further, UPFs contributed to 22.8% (%95CI 20.5% to 25.1%) of total salt intake, 24.0% (%95 CI, 21.4% to 26.6%) of fat intake and 18.6% (%95 CI, 16.5% to 20.7%) of sugar intake. UPFs contributed over 20% of total energy intake in this sample of Fijian adults and over 20% of salt, fat, and sugar. Messages and interventions that encourage consumption of minimally processed foods while reducing consumption of UPFs are likely needed to improve the healthiness of diets.

The objective of this study is to evaluate the association between the consumption of ultra-processed foods (UPF) and the mental health of pregnant women from the South of Brazil. This is a cross-sectional study carried out in Criciúma, Brazil, through face-to-face interviews, from April to December 2022. Pregnant women aged 18 or older who underwent prenatal care in the forty-eight basic health care units of the municipality and who were in their third trimester of pregnancy were included. High consumption of UPF was considered as six or more items or subgroups of UPF consumed on the day before the interview, using the Nova-UPF screener. The mental health variables were depressive symptoms, stress, sadness and anxiety. Crude and adjusted analyses were conducted using the Fisher’s exact test and the Poisson regression with robust variance. In total, 428 pregnant women were studied; most of them were aged between 20 and 25 years and were white. Pregnant women who presented high consumption of UPF were 1·42-fold (95 % CI 1·06, 1·92) more likely to experience anxiety and presented a prevalence 56 % (95 % CI 1·18, 2·07) higher of stress when compared with those who did not present high consumption of UPF. The prevalence of depressive symptoms and feelings of sadness was 1·31-fold (95 % CI 1·08, 1·60) and 3·41-fold (95 % CI 1·77, 6·58) higher among those with high consumption of UPF, respectively. The results suggest that diet quality is associated with the mental health of pregnant women. Promoting joint actions focused on food and nutritional education, and mental health, for pregnant women, is necessary.

The objective of this study was to describe the evolution of household purchase of added sugars and their main food sources in Brazil. Nationally representative data from the Household Budget Surveys from 2002–2003, 2008–2009 and 2017–2018 were used. Energy and added sugar quantities were estimated by means of per capita food quantities. The items considered as food sources were: (1) table sugar: refined sugar and other energetic sweeteners and (2) processed and ultra-processed foods with added sugar: soft drinks; other drinks; sweets, candies and chocolates; cookies; cakes and pies and other foods. The parameters estimated were: mean share of added sugar in total energy and, for food sources, the share of added sugar in total sugar intake and the impact of variations in sources of added sugar between 2008 and 2017. There was a regular share of energy from added sugar to total energy intake between 2002 and 2008 but a reduced share in 2017. Between 2008 and 2017, there was a decrease in the share of refined sugar and other sweeteners and soft drinks to total sugar intake and an increased share of all other items. High-income households had a lower share of refined sugar and other energetic sweeteners, but a higher share of soft drinks, sweets, candies and chocolates. The decrease in added sugar in 2017 was mainly due to the lower share of soft drinks. In conclusion, Brazilians’ total intake of added sugar was decreased, mostly owing to reduced consumption of sugar from soft drinks.

Ultra-processed plant-based foods, such as plant-based burgers, have gained in popularity. Particularly in the out-of-home (OOH) environment, evidence regarding their nutritional profile and environmental sustainability is still evolving. Plant-based burgers available at selected OOH sites were randomly sampled in Amsterdam, Copenhagen, Lisbon and London. Plant-based burgers (patty, bread and condiment) (n 41) were lab analysed for their energy, macronutrients, amino acids and minerals content per 100 g and serving and were compared with reference values. For the plant-based burgers, the median values per 100 g were 234 kcal, 20·8 g carbohydrates, 3·5 g dietary fibre and 12·0 g fat, including 0·08 g TFS and 2·2 g SFA. Protein content was 8·9 g/100 g, with low protein quality according to amino acid composition. Median Na content was 389 mg/100 g, equivalent to 1 g salt. Compared with references, the median serving provided 31% of energy intake based on a 2000 kcal per day and contributed to carbohydrates (17–28%), dietary fibre (42%), protein (40%), total fat (48%), SFA (26%) and Na (54%). One serving provided 15–23% of the reference values for Ca, K and Mg, while higher contributions were found for Zn, Mn, P and Fe (30–67%). The ultra-processed plant-based burgers provide protein, dietary fibre and essential minerals and contain relatively high levels of energy, Na and total fats. The amino acid composition indicated low protein quality. The multifaceted nutritional profile of plant-based burgers highlights the need for manufacturers to implement improvements to better support healthy dietary habits, including reducing energy, Na and total fats.

The study evaluated the association between ultra-processed foods (UPF) and nutrient intake and identified the socio-demographic characteristics associated with UPF consumption among a nationally representative sample of middle-older adults. Dietary assessment was collected in 2013 using a validated FFQ. The Nova system was used to classify food and drinks into UPF. The percentage of dietary energy from UPF was calculated and used throughout the analyses, and average nutrient intake across quintiles of UPF was evaluated. The determinants associated with the dietary caloric contribution of UPF intake were investigated using linear regression models. A cross-sectional analysis of a nationally representative study of Americans over the age of 50, the Health and Retirement Study, was conducted. The analysis included 6220 participants. The mean age was 65 (se 0·28) years, with 55 % being female. UPF intake accounted for 51 % (se 0·25) of total intake. An increase in the percentage of (%UPF) consumption was correlated with an increase in calories, carbohydrates, saturated fat and sugar, and a decrease in fibre, vitamins and minerals. %UPF intake was inversely associated with being Hispanic, higher income, physical activity, vegetarian diet and Mediterranean diet but positively associated with very low food insecurity. UPF represented half of the calories consumed. A higher %UPF intake was associated with a lower nutrient profile, suggesting decreasing %UPF intake as a strategy to improve the nutritional quality of middle-older adults. A few socio-demographic factors were associated with %UPF, which would help in planning strategies to reduce UPF consumption.

Broad variations in dietary and physical activity patterns are part of nutritional transition concept. An additional nutritional transition has as main characteristic the change of consumption of processed foods for ultra-processed foods (UPF). This study aims to evaluate trends of UPF availability in Portuguese population and its association with diet-related non-communicable diseases (NCD) health indicators. This ecological study used data from the Household Budget Surveys conducted by the National Statistics Institute each 5 years within a national representative sample of households. The percentage of UPF was calculated based on the total daily amount of food and beverages available per capita (in grams). Data from the years 1990, 1995, 2000 and 2005 were used, which were retrieved from DAFNE-Anemos Software. NCD age-standardised mortality, prevalence and incidence were obtained from the Global Burden of Disease database, for the years 2000, 2005, 2010 and 2015. Between 1990 and 2005, the UPF availability increased from 3·9 % to 13·8 %. Over the years, almost all food and beverages categories increased the UPF availability contribution, mainly noticeable for milk, sugar, cereal and meat products. Positive correlations were observed between UPF availability and digestive diseases both in prevalence (r = 0·062; P = 0·037) and incidence (r = 0·005; P = 0·010) measures. Neoplasms incidence also showed positive correlation with UPF availability (r = 0·002; P = 0·012). Trends in UPF availability in Portugal increased exponentially. At the same time, there is a trend towards a decrease in unprocessed and processed food availability. The Portuguese population should be made aware of the health risks resulting from excessive consumption of UPF.

This study aimed to evaluate the early introduction of ultra-processed foods (UPF) and identify its association with overweight and anaemia in Brazilian children living in a situation of social vulnerability. A population-based cross-sectional study was conducted in a Brazilian capital. Children aged 12-59 months were included. The presence of overweight and anaemia was evaluated, as well as the introduction of twelve different UPF in children’s first year of life. Association analysis was performed using Poisson regression, with robust estimates of variances. A total of 561 children were studied; 85·5 % had consumed at least one UPF evaluated in the first year of life; 19·1 % were overweight and 52·0 % were anaemic. Adjusted multivariate analyses identified that the early introduction of soft drinks (Prevalence Ratio (PR) = 1·18, 95 % CI (1·02, 1·38)), packaged snacks (PR = 1·17, 95 % CI (1·05, 1·30)) and powdered soft drinks (PR = 1·36, 95 % CI (1·16, 1·60)) increased the likelihood of children being overweight, and the early introduction of chocolate drink (PR = 1·25, 95 % CI (1·02, 1·53)) increased the likelihood of them being anaemic, when comparing children who consumed these UPF before reaching 1 year of age with those who consumed these foods at 12 months of age or older. From the results found, one can see the existing relationship between the early introduction of UPF with overweight and anaemia, being necessary to intensify public health policies to combat malnutrition, focusing on the promotion of proper and healthy eating, especially during the phase of food introduction, focusing on the population living in socially vulnerable situations.

Consumption of ultra-processed food (UPF) has been associated with several chronic diseases and poor diet quality. It is reasonable to speculate that the consumption of UPF negatively associates with flavonoid dietary intake; however, this assumption has not been previously examined. The present study aims to assess association between the dietary contribution of UPF and flavonoid intake in the US population aged 0 years and above. We performed a cross-sectional analysis of dietary data collected by 24-h recalls from 7640 participants participating in the National Health and Nutrition Examination Survey 2017–2018. Foods were classified according to the Nova classification system. The updated US Department of Agriculture (USDA) Database for the Flavonoid Content of Selected Foods (Release 3.3) database was used to estimate total and six classes of flavonoid intakes. Flavonoid intakes were compared across quintiles of dietary contribution of UPF (% of total energy intake) using linear regression models. The total and five out of six class flavonoid intakes decreased between 50 and 70 % across extreme quintiles of the dietary contribution of UPF (Pfor linear trend < 0·001); only isoflavones increased by over 260 %. Our findings suggest that consumption of UPF is associated with lower total and five of six class flavonoid intakes and with higher isoflavone intakes, supporting previous evidence of the negative impact of UPF consumption on the overall quality of the diet and health outcomes.
