- Consumption of ultra-processed foods and non-communicable disease-related nutrient profile in Portuguese adults and elderly (2015-2016): the UPPER project(2021) MIRANDA, Renata Costa de; RAUBER, Fernanda; MORAES, Milena Miranda de; AFONSO, Claudia; SANTOS, Cristina; RODRIGUES, Sara; LEVY, Renata BertazziThis study aims to investigate the dietary share of ultra-processed foods and its association with the non-communicable disease (NCD)-related nutrient profile of adult and elderly populations in Portugal. Cross-sectional data from the National Food, Nutrition and Physical Activity Survey (2015-2016) of the Portuguese population were analysed. Dietary intake was assessed by two non-consecutive 24-h recalls, and food items were classified according to the NOVA system. We estimated the percentage of dietary energy provided by each of the NOVA food groups and assessed the NCD-related nutrient profile of the overall diet across quintiles of ultra-processed food consumption. Weighted t tests, besides crude and adjusted linear and Poisson regressions, were performed. Ultra-processed foods contributed to around 24 and 16 % of daily energy intake for adults and elderly, respectively. In both groups, as the consumption of ultra-processed foods increased, the dietary content of free sugars, total fats and saturated fats increased, while the dietary content of protein decreased. In adults, total energy intake, dietary energy density and content of carbohydrates also increased as the consumption of ultra-processed foods increased, while the dietary content of fibre, Na and K decreased. The prevalence of those exceeding the upper limits recommended for free sugars and saturated fats increased by 544 and 153 % in adults and 619 and 60 % in elderly, when comparing the lowest with the highest quintile of ultra-processed food consumption. Such a scenario demands for effective strategies addressing food processing in the Portuguese population to improve their diet quality and prevention against diet-related NCD.
- Ultra-processed food consumption deteriorates the profile of micronutrients consumed by Portuguese adults and elderly: the UPPER project(2023) ANTONIAZZI, Luiza; MIRANDA, Renata Costa de; RAUBER, Fernanda; MORAES, Milena Miranda de; AFONSO, Claudia; SANTOS, Cristina; LOPES, Carla; RODRIGUES, Sara; LEVY, Renata BertazziPurpose This study aims to describe micronutrient intake according to food processing degree and to investigate the association between the dietary share of ultra-processed foods and micronutrient inadequacies in a representative sample of Portuguese adult and elderly individuals. Methods Cross-sectional data from the National Food, Nutrition and Physical Activity Survey (2015/2016) were used. Food consumption data were collected through two 24-h food recalls, and food items were classified according to the NOVA system. Linear regression models were used to assess the association between the micronutrient density and the quintiles of ultra-processed food consumption-crude and adjusted. Negative Binomial regressions were performed to measure the prevalence ratio of micronutrient inadequacy according to ultra-processed food quintiles. Results For adults, all evaluated vitamins had significantly lower content in the fraction of ultra-processed foods compared to unprocessed or minimally processed foods, except vitamin B2. For the elderly, out of ten evaluated vitamins, seven presented significantly less content in ultra-processed foods compared to non-processed ones. The higher energy contribution of ultra-processed foods in adults was associated with a lower density of vitamins and minerals. This association was not observed in the elderly. For adults, compared with the first quintile of ultra-processed food consumption, the fifth quintile was positively associated with inadequate intakes of vitamin B6 (PR 1.51), vitamin C (PR 1.32), folate (PR 1.14), magnesium (PR 1.21), zinc (PR 1.33), and potassium (PR 1.19). Conclusion Our results corroborate the importance of public health actions that promote a reduction in the consumption of ultra-processed foods.

This work aimed to explore the UPF consumption associated factors and its main dietary sources, by sex, in Portugal. Participants from the National Food, Nutrition and Physical Activity Survey (IAN-AF) 2015-2016, aged 3-84 years, were included (n 5005). Dietary intake was assessed through two 1-day food diaries/24 h recalls. UPFs were identified using the NOVA classification. Associations were evaluated through linear regression models. Median UPF consumption was 257 g/d (10.6 % of total quantity; 23.8 % of total energy). Adolescents were those with higher consumption (490 g/d). Compared to adults, younger ages were positively associated with UPF consumption (e.g. adolescents ((beta) over cap -females: 192, 95 % confidence interval (CI): 135, 249; (beta) over cap -males: 327, 95 % CI: 277, 377)). A lower educational level was associated with lower UPF consumption ((beta) over cap -females: -63; 95 % CI: -91, -34; (beta) over cap -males: -68; 95 % CI: -124, -12). Also, a lower UPF consumption was observed in married males/couples compared to singles ((beta) over cap: -48, 95 % CI: -96, -1). Furthermore, female current/former smokers were associated with a higher UPF consumption v. never smokers ((beta) over cap: 79, 95 % CI: 41, 118; (beta) over cap: 42, 95 % CI: 8, 75, respectively). Main UPF sources were yoghurts, soft drinks and cold meats/sausages differing strongly by sex, age and education level. Yoghurts containing additives were the main contributors to the UPF consumption in children and adult females from all education (similar to 20 %). Soft drinks were leaders in adolescents (females: 26.0 %; males: 31.6 %) and young male adults (24.4 %). Cold meats/sausages stood out among low-educated males (20.5 %). Males, younger age groups, higher education, children with less-educated parents, married/couple males and smoking females were positively associated with UPF consumption.
conferenceObject Mediterranean diet, sociodemographic factors and ultra-processed food consumption in Portugal(2020) MORAES, M. M.; OLIVEIRA, B.; AFONSO, C.; SANTOS, C.; MIRANDA, R. C.; RAUBER, F.; LEVY, R. B.; RODRIGUES, S.- Impact of ultra-processed food consumption on metabolic health(2021) MIRANDA, Renata Costa de; RAUBER, Fernanda; LEVY, Renata BertazziPurpose of review Ultra-processed foods (UPF) have been associated with poor diet quality and adverse health outcomes. Our aim in this review is to summarize recent research assessing the impact of UPF consumption, classified according to the NOVA system, on outcomes related to metabolic health. Recent findings Thirty recent studies with different design, quality and target population have investigated the impact of UPF consumption on parameters related to metabolic health, which were organized into: metabolic syndrome; body weight change and obesity indicators; blood pressure and hypertension; glucose profile, insulin resistance and type 2 diabetes; other metabolic risks and cardiovascular diseases and mortality. Most of the studies demonstrated adverse associations between high UPF consumption and metabolic health, mainly those with robust design and involving adults. Most of the latest findings have revealed an adverse impact of high UPF consumption on metabolic health, including cardiovascular diseases and mortality. Scientific evidence is accumulating towards the necessity of curbing UPF consumption worldwide at different life stages. Nevertheless, other studies are needed to confirm the causality between UPF consumption and metabolic health in diverse scenarios and to better elucidate all likely mechanisms involved in this relationship.
