RESUMO

Aromatic amino acid oxidation products (AAAOPs) are newly discovered risk substances of thermal processes. Due to its significant polarity and trace level in food matrices, there are no efficient pre-treatment methods available to enrich AAAOPs. Herein, we proposed a magnetic cationic covalent organic framework (Fe3O4@EB-iCOF) as an adsorbent for dispersive magnetic solid-phase extraction (DMSPE). Benefiting from the unique charged characteristics of Fe3O4@EB-iCOF, AAAOPs can be enriched through electrostatic interaction and π-π interactions. Under the optimal DMSPE conditions, the combined HPLC-MS/MS method demonstrated good linearity (R2 ≥ 0.990) and a low detection limit (0.11-7.5 µg·kg-1) for AAAOPs. In addition, the method was applied to real sample and obtained satisfactory recoveries (86.8 % âˆ¼ 109.9 %). Especially, we applied this method to the detection of AAAOPs in meat samples and conducted a preliminarily study on its formation rules, which provides a reliable basis for assessing potential dietary risks.

RESUMO

For thousands of years, people have used medicinal plants and in many parts of the world, traditional medicines continue to play a significant role in the standard treatment of a wide range of illnesses. With changes in modern eating patterns, there has recently been an increase in the use of processed foods. Furthermore, the use of food additives has increased in tandem with the production of processed foods. The dosage levels used for these additives are determined using empirical analyses. However, some additives have demonstrated long-term toxic effects on the human body in toxicity tests. Plants are one of the main sources of biologically active substances and in recent years, many studies have focused on the health benefits of phytochemicals and plant-derived extracts in the treatment and prevention of food additive toxicity. This review clarified studies on several medicinal plants, such as <i>Physalis peruviana</i> L., <i>Jatropha tanjorensis</i>, <i>Cymbopogon citratus</i>,<i> Ficus carica</i>, <i>Rosmarinus officinalis</i> L. and others. The findings presented here demonstrate these plants' efficiency and success in preventing and lowering the toxicity of food additives through antioxidant activity reducing oxidative stress, and reduction in renal and hepatic toxicity. Therefore, these plant extracts have a preventive and therapeutic effect in reducing toxicity and may be the best option for reducing the toxicity of food additives in the future. Moreover, additional research is required to confirm the biologically active components found in medicinal plants that are effective in reducing this toxicity.

RESUMO

The school food environment is a key intervention point for influencing children's and adolescents' diets. As more countries establish school meal programs to provide critical nourishment to students, establishing standards for the foods served can increase the consumption of key nutrients and limit the consumption of foods that do not build health. This global scoping review explores the prevalence and basic characteristics of national policies that regulate food served through school meals across 193 countries, particularly by restricting the provision of categories, nutrients, or ingredients of nutritional concern. We gathered evidence from policy databases, grey literature, peer-reviewed literature, and primary policy documents. We included nationally mandated policies that included restrictions on categories, nutrients, or ingredients of concern served in school meals. Policies that were sub-national, voluntary, and/or did not include restrictive language were excluded from this review. Data was collected in research electronic data capture then extracted into Microsoft Excel and analyzed for policy frequency, prevalence by world region or country income group, and prevalence of certain policy characteristics. Globally, only 15% of countries were found to have a national-level policy restricting foods served through school meals in some capacity, including either nutritional or categorical restrictions. The majority of these policies were found in high-income countries, and no low-income countries had a policy meeting inclusion criteria. Policies in Latin-American and Caribbean countries limited the content of more nutrients of concern than in other regions. Although many policies included explicit guidelines to monitor implementation, few outlined mechanisms for policy enforcement. Future research should evaluate the impact of various school meal regulatory approaches, including implementation of similar policies at sub-national levels, and other elements that affect the impact of school meal programs, such as procurement, infrastructure, costs to school and to students and their families, and acceptability and consumption of foods provided.

RESUMO

BACKGROUND: In recent years, there has been a lot of discussion over the impact of ultra-processed foods (UPFs) intake on overall health of subjects. However, the association between UPFs intake and metabolic unhealthy (MU) status is still in a state of ambiguity. The current study assessed the relationship between UPFs intake and MU status with regard to brain-derived neurotrophic factor (BDNF) and adropin levels. METHODS: A sample of Iranian adults (aged 20-65 years) was selected to participate in this cross-sectional study using a multistage cluster random-sampling method. UPFs intake was assessed by a validated food frequency questionnaire and NOVA classification. Concentrations of metabolic parameters, BDNF and adropin were determined through fasting blood samples. MU status was assessed according to the criteria proposed by Wildman. RESULTS: The overall prevalence of MU phenotype among study participants (n = 527) was 42.5%. Higher intake of UPFs was associated with elevated odds of MU status in multivariable-adjusted model (ORT3 vs. T1=1.88; 95%CI: 1.02-3.45). Moreover, a positive association was observed between UPFs intake and hypertriglyceridemia after controlling all confounders (ORT3 vs. T1=2.07; 95%CI: 1.15-3.73). However, each tertile increase in UPFs intake was not significantly associated with serum BDNF ([Formula: see text]=0.15; 95%CI: -0.05, 0.34; P = 0.14) and adropin ([Formula: see text]=-1.37; 95%CI: -6.16, 3.42; P = 0.58) levels in multivariable-adjusted linear regression models. CONCLUSION: Our findings suggested that higher consumption of UPFs was related to increased likelihood of MU status among a sample of Iranian adults. Further longitudinal studies are needed to verify the directionality and generalizability of the results to all adult populations.

RESUMO

BACKGROUND: Nutrient content and degree of processing are complementary but distinct concepts, and a growing body of evidence shows that ultra-processed foods (UPFs) can have detrimental health effects independently from nutrient content. 10 + countries currently mandate front-of-package labels (FOPL) to inform consumers when products are high in added sugars, saturated fat, and/or sodium. Public health advocates have been calling for the addition of ultra-processed warning labels to these FOPLs, but the extent to which consumers would understand and be influenced by such labels remains unknown. We examined whether the addition of ultra-processed warning labels to existing nutrient warning labels could influence consumers' product perceptions and purchase intentions. METHODS: In 2023, a sample of adults in Brazil (n = 1,004) answered an open-ended question about the meaning of the term "ultra-processed," followed by an online experiment where they saw four ultra-processed products carrying warning labels. Participants were randomly assigned to view either only nutrient warning labels or nutrient plus ultra-processed warning labels. Participants then answered questions about their intentions to purchase the products, product perceptions, and perceived label effectiveness. RESULTS: Most participants (69%) exhibited a moderate understanding of the term "ultra-processed" prior to the experiment. The addition of an ultra-processed warning label led to a higher share of participants who correctly identified the products as UPFs compared to nutrient warning labels alone (Cohen's d = 0.16, p = 0.02). However, the addition of the ultra-processed warning label did not significantly influence purchase intentions, product healthfulness perceptions, or perceived label effectiveness compared to nutrient warning labels alone (all p > 0.05). In exploratory analyses, demographic characteristics and prior understanding of the concept of UPF did not moderate the effect of ultra-processed warning labels. CONCLUSIONS: Ultra-processed warning labels may help consumers better identify UPFs, although they do not seem to influence behavioral intentions and product perceptions beyond the influence already exerted by nutrient warning labels. Future research should examine how ultra-processed warning labels would work for products that do and do not require nutrient warnings, as well as examine the benefits of labeling approaches that signal the health effects of UPFs.

RESUMO

INTRODUCTION: University students experienced significant changes in their routines with the implementation of remote learning during Covid-19 pandemic, including increase in sedentary behavior (SB) time and ultra-processed foods (UPF's) consumption, which may have influenced changes in body mass index (BMI). OBJECTIVE: To evaluate the association between the variation in SB time and UPF's consumption with the variation in BMI, before and during the pandemic, in university students. METHODS: This is a cross-sectional study, conducted between November 2020 and February 2021, with students from a public university of Southeast of Brazil, who answered an online questionnaire with questions regarding to the period before and during the pandemic. SB was assessed through questions about time spent on TV and electronic devices. A score of the frequency of UPF's consumption was estimated based on the Brazilian Food Guide. Self-reported information on height and body mass was used to calculate BMI. RESULTS: The sample comprised 3390 university students, with an average age of 28.7 (± 10.0) years. Among them, 65.4% were undergraduates, and 66.9% were women. SB time, UPF score, and BMI increased significantly during the pandemic, compared to the previous period. In this population, there was a significant association between increased SB time (ß = 0.06; SE = 0.01; p < 0.001) and UPF score (ß = 0.08; SE = 0.01; p < 0.001) with an increase in BMI. CONCLUSION: Changes in SB time and UPF score were associated with an increase in BMI before and during the COVID-19 pandemic in students from a Brazilian University.

RESUMO

Objectives: The association between ultra-processed foods (UPF) consumption and cognitive performance needs to be better characterized in adolescents, especially in low-income settings, where the cost of human capital is high. This study investigated the association between cognitive performance and UPF in adolescents from the countryside of the Brazilian Northeast. Methods: Adolescents (15-18 years old) from three public high schools were included. Food intake was assessed using three 24-hour dietary recalls. The classification of foods as UPF was determined according to the Nova classification. Cognitive performance was evaluated using the Non-Verbal General Intelligence Test. Results: 116 adolescents were included, of which 50 (43.1%) showed low cognitive performance. The average energy intake was 1973.5 kcal, with 24.2% coming from UPF. Participants with low cognitive performance consumed 26.5% (95% CI: [22.2; 30.7]%) of daily energy intake from UPF compared to 22.5% ([18.8; 26.2]%) of those with medium-high cognitive performance (P = 0.17), without differences in energy and macronutrient intake. Conclusion: Despite similar UPF consumption compared to the Brazilian average, no association was found between UPF consumption and cognitive performance in this low-income adolescent sample.

RESUMO

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.

RESUMO

PURPOSE: (i) Characterize ultra-processed food (UPF) intakes in toddlerhood and mid-childhood, including identifying principal UPF sub-groups and associations with nutrient profile; (ii) explore stability and change in UPF intake between toddlerhood and mid-childhood. METHODS: Data were from children in the UK Gemini twin cohort at 21 months (n = 2,591) and 7 years (n = 592) of age. UPF intakes were estimated using diet diaries and Nova classification. Complex samples general linear or logistic regression models were used to explore associations between UPF intake, UPF sub-groups and nutrients, and changes in intake over time. RESULTS: The contribution of UPF to total energy was 46.9% (± 14.7) at 21 months and 59.4% (± 12.5) at 7 years. Principal UPF sub-groups were yogurts, higher-fiber breakfast cereals, and wholegrain breads in toddlerhood, and puddings and sweet cereal products and white breads in mid-childhood. At both ages, mean free sugar and sodium intakes exceeded recommended maximums and higher UPF consumption was associated with consuming more of each nutrient (P < 0.001). UPF intake was negatively associated with fat, saturated fat and protein intake in toddlerhood, and fiber intake in mid-childhood (P < 0.001). Being in the highest UPF intake quintile in toddlerhood was predictive of being in the highest quintile in mid-childhood (OR 9.40, 95%CI 3.94-22.46). CONCLUSIONS: UPF accounted for nearly half of toddlers' energy, increasing to 59% in mid-childhood. Higher UPF consumers had higher intakes of free sugar and sodium. UPF intake in toddlerhood was predictive of mid-childhood intake. Effective policies are needed to reduce UPF intakes in the early years.

RESUMO

OBJECTIVE: To assess the availability and marketing of ultra-processed foods (UPFs) in modern retail food outlets (supermarkets and minimarts) in Kenya and associated factors. DESIGN: This cross-sectional study was conducted in Kenya from August 2021 to October 2021. Variables included; the geographic location and the socioeconomic status levels (SES), the food items displayed for sale and advertised in the stores, and locations in the stores such as the entrance. SETTING: Three counties in Kenya (Nairobi - urban, Mombasa - coastal tourist, and Baringo- rural). Each county was stratified into high and low SES using national poverty indices. PARTICIPANTS: Food outlets that offered a self-service, had at least one check-out, and had a minimum of two stocked aisles were assessed. RESULTS: Of 115 outlets assessed, UPFs occupied 33% of the cumulative shelf space. UPFs were the most advertised foods (60%) and constituted 40% of foods available for sale. The most commonly used promotional characters were cartoon characters (18%). UPFs were significantly more available for sale in Mombasa (urban) compared to Baringo (rural) (Adjusted prevalence rate ratios (APRR): 1.13, 95% confidence interval (CI): 1.00-1.26, p=0.005). UPFs advertisements were significantly higher in Mombasa ((APRR): 2.18: 1.26-3.79, p= 0.005) compared to Baringo and Nairobi counties. There was a significantly higher rate of advertisement of UPFs in larger outlets ((APRR): 1.68: 1.06-2.67 p=0.001) compared to smaller outlets. CONCLUSIONS: The high marketing and availability of UPFs in modern retail outlets in Kenya calls for policies regulating unhealthy food advertisements in different settings in the country.

RESUMO

OBJECTIVE: To assess the current Na levels in a variety of processed food groups and categories available in the Argentinean market to monitor compliance with the National Law and to compare the current Na content levels with the updated Pan American Health Organisation (PAHO) regional targets. DESIGN: Observational cross-sectional study. SETTING AND PARTICIPANTS: Argentina. Data were collected during March 2022 in the city of Buenos Aires in two of the main supermarket chains. We carried out a systematic survey of pre-packaged food products available in the food supply assessing Na content as reported in nutrition information panels. RESULTS: We surveyed 3997 food products, and the Na content of 760 and 2511 of them was compared with the maximum levels according to the Argentinean law and the regional targets, respectively. All food categories presented high variability of Na content. More than 90 % of the products included in the National Sodium Reduction Law were found to be compliant. Food groups with high median Na, such as meat and fish condiments, leavening flour and appetisers are not included in the National Law. In turn, comparisons with PAHO regional targets indicated that more than 50 % of the products were found to exceed the regional targets for Na. CONCLUSIONS: This evidence suggests that it is imperative to update the National Sodium Reduction Law based on regional public health standards, adding new food groups and setting more stringent legal targets.

RESUMO

OBJECTIVE: To evaluate the association between ultra-processed food consumption and adherence to the EAT-Lancet diet in a representative sample of the Brazilian population. DESIGN: The study used data from the Brazilian National Dietary Survey 2017-2018 and employed linear regression models to evaluate the association between ultra-processed food consumption and adherence to the EAT-Lancet diet, as measured by the Nova food system and Planetary Health Diet Index (PHDI), respectively. SETTING: Nationally representative sample of the Brazilian population. PARTICIPANTS: The study included 46 164 Brazilians ≥ 10 years old. RESULTS: The average PHDI total score was 45·9 points (95 % CI 45·6, 46·1). The ultra-processed food consumption was, with dose-response, inversely associated with the adherence to the EAT-Lancet diet. The PHDI total score was 5·38 points lower (95 % CI -6·01, -4·75) in individuals in the highest quintile of consumption of ultra-processed foods, as compared to those in the first quintile. The PHDI score was also inversely associated with the share of processed culinary ingredients and processed foods and positively associated with the share of unprocessed or minimally processed foods. CONCLUSIONS: Our study showed an inverse relationship between the consumption of ultra-processed foods and the adherence to a healthy and sustainable diet.

RESUMO

BACKGROUND: Among the crises engulfing the world is the symbiotic rise of ultra-processed foods (UPFs) and plastics. Together, this co-dependent duo generates substantial profits for agri-food and petrochemical industries at high costs for people and planet. Cheap, lightweight and highly functional, plastics have ideal properties that enable business models to create demand for low-cost, mass-produced and hyper-palatable UPFs among populations worldwide, hungry, or not. Evidence linking UPF consumption to deterioration in diet quality and higher risk of chronic diseases is well-established and growing rapidly. At the same time, the issue of plastic food contact chemicals (FCCs) is receiving increasing attention among the human health community, as is the generation and dispersion of micro- and nanoplastics. MAIN BODY: In this commentary, we explore how the lifecycles and shared economic benefits of UPFs and plastics interact to co-produce a range of direct and indirect harms. We caution that the chemical dimension of these harms is underappreciated, with thousands of plastic FCCs known to migrate into foodstuffs. Some of these are hazardous and have been detected in humans and the broader environment, while many are yet to be adequately tested. We question whether policies on both UPF and plastic chemicals are fit for purpose when production and consumption of these products is adding to the chronic chemical exposures that plausibly contribute to the increasing global burden of non-communicable diseases. CONCLUSIONS: In the context of ongoing negotiations for a legally binding global treaty to end plastics pollution, and rapidly growing concern about the burgeoning share of UPFs in diets worldwide, we ask: What steps are needed to call time on this toxic relationship?

RESUMO

This study reviewed the current state of meat alternatives including plant-based or cell-based ingredients and discussed the contentious factor surrounding the classification of meat alternatives as ultra-processed foods (UPFs). The term UPFs refers to foods undergoing extensive industrial processing and containing additives such as flavors, colors, emulsifiers, and preservatives. There is growing concern regarding the potential adverse effects of UPF consumption on health, nutrition, and sociodemographic factors. Additionally, this study examined the market potential, drivers, and barriers associated with different types of meat alternatives. In light of barriers focused on UPFs, meat alternatives can be disputed in that they undergo extensive processing and are highly processed, including numerous ingredients, while meat alternatives offer potential solutions to the environmental, ethical, and health issues associated with animal meat consumption. Consequently, it is important to distinguish them from other UPFs, which are known to have detrimental effects on health. Therefore, this paper proposed a reassessment of the UPF classification system, the establishment of uniform nutritional profiles for meat alternatives, and the dissemination of their beneficial impacts. These measures are necessary to validate the exclusion of meat alternatives from the UPF category and to promote their development and adoption.

RESUMO

OBJECTIVE: To compare nutritional value and aspects with environmental impact of high-protein (HP) and 'normal-protein' (NP) ultra-processed foods (UPF). DESIGN: 299 HP and 286 NP products were evaluated regarding aspects of nutritional value, energy density, Nutri-Score, number of additives as well as hyper-palatability and price. Environmental impact of HP UPF was addressed by analysing protein sources and the use of environmentally persistent non-nutritive artificial sweeteners. SETTING: Cross-sectional market analysis in German supermarkets and online shops. PARTICIPANTS: 299 HP and 286 NP UPF products. RESULTS: HP compared to NP UPF had a lower energy density, a lower content of sugar, total and saturated fat, whereas fibre and protein content (62·2 % animal protein) were higher (all P < 0·001). HP products therefore had a higher prevalence of Nutri-Score A (67·2 % v. 21·7 %) and a lower prevalence of Nutri-Score E (0·3 % v. 11·2 %) labelling (both P < 0·001). By contrast, salt content and the number of additives (environmentally persistent sweeteners, sugar alcohols, flavourings) were higher in HP compared to NP UPF (P < 0·001). When compared to HP products, twice as many NP were identified as hyper-palatable (82·5 % v. 40·5 %; P < 0·001). The price of HP was on average 132 % higher compared to NP UPF (P < 0·001). CONCLUSIONS: While major adverse aspects of UPF regarding nutritional profile and hyper-palatability are less pronounced in HP compared to NP products, higher salt content, increased number of additives and negative environmental effects from frequent use of animal protein and environmentally persistent sweeteners are major drawbacks of HP UPF.

RESUMO

PURPOSE OF REVIEW: Adequate and balanced nutrition during pregnancy is essential for both the mother's and fetus's health. The increased dietary intake of ultra-processed foods (UPFs) and their significant share in the diet negatively affects diet quality and gestational weight gain during pregnancy. The aim of this systematic review was to examine the association of UPFs consumption with diet quality and gestational weight change among healthy pregnant women, using data from observational studies (PROSPERO Identifier: CRD42023468269) from the last 10 years. RECENT FINDINGS: A search was performed in Pubmed, Wiley, Scopus, and Web of Science, and studies published in english language were selected. Study selection and data extraction were made by determining the exclusion and eligible inclusion criterias according to the PECOS framework. Of the 12 studies included, 5 were longitudinal cohort studies and 7 were cross-sectional studies. On average, half of the energy in the participants' daily diets came from UPFs in 3 studies, but the energy share of UPFs was about 20-30% in the remainder studies. UPFs-enriched maternal diet was associated with less dietary intake of legumes, vegetables, fruits and protein sources (seafood and plant protein, total protein) and greater consumption of refined grains compared to those who consume less UPFs. In parallel, UPFs consumption was negatively associated with Healthy Eating Index. UPF intake during pregnancy has a negative impact on diet quality and gestational weight gain. Increasing awareness of UPFs during this period may reduce potential complications during pregnancy and fetal growth.

RESUMO

BACKGROUND: There is a need to understand the underlying biological mechanisms through which ultra-processed foods negatively affect health. Proteomics offers a valuable tool with which to examine different aspects of ultra-processed foods and their impact on health. OBJECTIVES: The aim of this study was to identify protein biomarkers of usual ultra-processed food consumption and assess their relation to the incidence of coronary heart disease (CHD), chronic kidney disease (CKD), and all-cause mortality risk. METHODS: A total of 9361 participants from the Atherosclerosis Risk in Communities visit 3 (1993-1995) were included. Dietary intake was assessed using a 66-item food-frequency questionnaire and the processing levels were categorized on the basis of the Nova classification. Plasma proteins were detected using an aptamer-based proteomic assay. We used multivariable linear regressions to examine the association between ultra-processed food and proteins, and Cox proportional hazard models to identify associations between ultra-processed food-related proteins and health outcomes. Models extensively controlled for sociodemographic characteristics, health behaviors, and clinical factors. RESULTS: Eight proteins (6 positive, 2 negative) were identified as significantly associated with ultra-processed food consumption. Over a median follow-up of 22 y, there were 1276, 3084, and 5127 cases of CHD, CKD, and death, respectively. Three, 5, and 3 ultra-processed food-related proteins were associated with each outcome, respectively. One protein (ß-glucuronidase) was significantly associated with a higher risk of all 3 outcomes, and 3 proteins (receptor-type tyrosine-protein phosphatase U, C-C motif chemokine 25, and twisted gastrulation protein homolog 1) were associated with a higher risk of 2 outcomes. CONCLUSIONS: We identified a panel of protein biomarkers that were significantly associated with ultra-processed food consumption. These proteins may be considered potential biomarkers for ultra-processed food intake and may elucidate the biological processes through which ultra-processed foods impact health outcomes.

RESUMO

BACKGROUND: Globally, dietary patterns are shifting toward an increased consumption of ultra-processed foods, raising the risk of some metabolic and nutritional diseases from a young age. This trend is now also affecting low- and middle-income countries. Considering this, we aimed to assess the contribution of ultra-processed foods to total energy intake and their association with the nutritional intake of children and adolescents in Cantagalo, São Tomé and Príncipe. METHODS: We conducted a cross-sectional study with a sample of 546 households. Data were collected on anthropometrics, sociodemographic characteristics, and lifestyle, including 24 h food recall questionnaires for children and adolescents. The reported foods were nutritionally assessed and categorized according to the NOVA classification to estimate the contribution of ultra-processed foods. Logistic regression models were used to estimate the magnitude of the associations between higher consumption of ultra-processed foods and nutritional intake, adjusting for confounders. RESULTS: The contribution of ultra-processed foods to daily energy intake was 9.5% for girls and 8.5% for boys. Higher consumption of ultra-processed foods was significantly associated with a lower intake of fiber (OR = 0.932; 95%CI, 0.872-0.996), vitamin B12 (OR = 0.812; 95%CI, 0.668-0.985), and zinc (OR = 0.443; 95%CI, 0.308-0.639) and a higher intake of iron (OR = 1.479; 95%CI, 1.065-2.055) and sodium (OR = 1.001; 95%CI, 1.000-1.001), after adjusting for confounders. CONCLUSION: Higher consumption of ultra-processed foods was especially associated with a lower intake of fiber, vitamin B12, and zinc, and with a higher intake of iron.

RESUMO

Ultra-processed food (UPF) intake is rising in low- and middle-income countries, where non-communicable diseases are now the leading contributor to disease burden. The purpose of this study was to assess awareness and knowledge of UPFs, factors that influence consumption of UPFs, and beliefs about the relationship between UPF intake and health among young people (18-20 years old) in a metropolitan area of the Philippines, a lower middle-income country. We conducted eight focus group discussions across four strata defined by gender and urban-rural neighborhood designation. We applied deductive and inductive codes to transcripts and organized codes into themes. Sixty participants were included in the study. Although most were unfamiliar with the concept of UPFs, participants demonstrated an intuitive understanding of the meaning of the term. Vendors in or around schools were commonly reported as a source of UPFs, though most participants reported consuming UPFs at home as well. Factors that were reported as having influence over participants' UPF intake included taste, convenience, cost, influence from parents, peers, and others, and health knowledge and status. Participants expressed various beliefs about the link between overconsumption of UPFs and risk of multiple health outcomes, including diabetes, hypertension, and kidney disease. Some males, but not females, believed that some UPFs were neutral or beneficial with respect to health. Commonly cited sources of information about UPFs and their link to health included parents, schools, and social media. This study provides important insights into the factors that drive UPF consumption among young people in a lower middle-income country and should inform efforts to reduce UPF intake among young people in this and similar settings.

RESUMO

INTRODUCTION: Limited evidence exists on the relationship between ultra-processed food (UPF) consumption and overweight/obesity amongst young children. This study aimed to assess UPF consumption, its socioeconomic correlates and its association with overweight/obesity amongst under-five children in Lebanon. MATERIALS AND METHODS: Data pertinent to children aged 6 months to 4.9 years (n = 893) from a cross-sectional national survey were used. Anthropometric measurements were obtained, and multi-component questionnaires were administered to mothers. Dietary intake was assessed using the 24-h recall approach. NOVA classification was used to assign food items into four groups according to the extent of industrial processing. Contributions of each group to total energy intake (EI) and macronutrient and micronutrient intakes were estimated. Regression models were conducted to explore the correlates of UPF consumption as well as the association between UPF consumption and overweight/obesity status. RESULTS: UPFs were found to contribute 47% of daily EI. Girls and children with higher household income had significantly higher UPF intakes. Children whose mothers had an intermediate, high school, or technical diploma and were employed and whose fathers had higher education levels consumed significantly less EI from UPFs. Children whose %EI fell within the second and third tertiles of UPF intake had significantly higher odds of overweight/obesity as compared to those in the first tertile (adjusted odds ratio [AOR]: 1.21, 95% confidence interval [CI]: 1.09, 1.32 and AOR: 1.61, 95% CI: 1.47, 1.76, respectively), after adjusting for confounders. CONCLUSION: The high intake of UPFs coupled with its association with overweight/obesity call for public health nutrition interventions aimed at improving feeding and dietary practices in this age group.
