RESUMO
Introduction: Cashew nut contains bioactive compounds that modulate satiety and food intake, but its effects on body fat during energy restriction remains unknown. This study aimed to assess the effects of cashew nut and cashew nut oil on body fat (primary outcome) as well as adiposity, cardiometabolic and liver function markers (secondary outcomes). Materials and methods: An eight-week (8-wk) randomized controlled-feeding study involved 68 adults with overweight/obesity (40 women, BMI: 33 ± 4 kg/m2). Participants were randomly assigned to one of the energy-restricted (-500 kcal/d) groups: control (CT, free-nuts), cashew nut (CN, 30 g/d), or cashew nut oil (OL, 30 mL/d). Body weight, body composition, and blood collection were assessed at the baseline and endpoint of the study. Results: After 8-wk, all groups reduced significantly body fat (CT: -3.1 ± 2.8 kg; CN: -3.3 ± 2.7 kg; OL: -1.8 ± 2.6 kg), body weight (CT: -4.2 ± 3.8 kg; CN: -3.9 ± 3.1 kg; OL: -3.4 ± 2.4 kg), waist (CT: -5.1 ± 4.6 cm; CN: -3.9 ± 3.9 cm; OL: -3.7 ± 5.3 cm) and hip circumferences (CT: -2.9 ± 3.0 cm; CN: -2.7 ± 3.1 cm; OL: -2.9 ± 2.3 cm). CN-group reduced liver enzymes (AST: -3.1 ± 5.3 U/L; ALT: -6.0 ± 9.9 U/L), while the OL-group reduced LDL-c (-11.5 ± 21.8 mg/dL) and atherogenic index (-0.2 ± 0.5). Both intervention groups decreased neck circumference (CN: -1.0 ± 1.2 cm; OL: -0.5 ± 1.2 cm) and apo B (CN: -6.6 ± 10.7 mg/dL; OL: -7.0 ± 15.3 mg/dL). Conclusion: After an 8-wk energy-restricted intervention, all groups reduced body fat (kg), weight, and some others adiposity indicators, with no different effect of cashew nut or cashew nut oil. However, participants in the intervention groups experienced additional reductions in atherogenic marker, liver function biomarkers, and cardiovascular risk factors (neck circumference and apo B levels), with these effects observed across the OL group, CN group, and both intervention groups, respectively.Clinical trial registration:https://ensaiosclinicos.gov.br/rg/RBR-8xzkyp2, identifier 8xzkyp2.
RESUMO
BACKGROUND: Obesity is associated with low-grade inflammation and increased intestinal permeability (IP). The Brazil nut (BN) (Bertholletia excelsa H.B.K.) appears to be a promising dietary intervention to control inflammation by enhancing antioxidant defenses. OBJECTIVES: We aimed to assess the effect of daily BN consumption on inflammatory biomarkers and IP in the context of an energy-restricted intervention. Furthermore, we evaluated the correlation between the changes in these inflammatory markers and the changes in serum selenium and IP. METHODS: In this 8-wk nonrandomized controlled trial, 56 women with overweight or obesity were allocated into 2 groups, both following an energy-restricted diet (-500 kcal/d). The control group (CO) consumed a nut-free diet, while the BN group consumed 8 g BN/d, providing 347.2 µg selenium (Se). Inflammatory cytokines were analyzed in plasma and Se in serum. IP was assessed using the lactulose/mannitol test (LM ratio). RESULTS: Forty-six women completed the intervention. Both groups achieved similar energy restriction (CO Δ= -253.7 ± 169.4 kcal/d; BN Δ= -265.8 ± 141.8 kcal/d) and weight loss (CO Δ= -2.5 ± 0.5 kg; BN Δ= -3.5 ± 0.5 kg). The BN group showed lower values of C-reactive protein, tumor necrosis factor, interleukin (IL)1-ß, IL-8, percentage lactulose excretion, and LM ratio than the CO group. Additionally, changes in serum Se concentration were predictive of changes in IL-8 concentration (ß: -0.054; adjusted R2: 0.100; 95% confidence interval [CI]: -0.100; -0.007; P = 0.025), and changes in IL-8 were predictive of changes in the LM ratio (ß: 0.006; adjusted R2: 0.101; 95% CI: 0.001, 0.011; P = 0.024). CONCLUSIONS: Regular intake of BNs can be a promising complementary dietary strategy for controlling low-grade inflammation and improving IP in women with overweight/obesity undergoing energy-restricted treatment. However, the effects of BNs seem to be Se status-dependent. This trial was registered at the Brazilian Registry of Clinical Trials (ReBEC: https://ensaiosclinicos.gov.br/rg/RBR-3ntxrm/.

RESUMO
High scores of lymphocyte-to-high-density lipoprotein cholesterol ratio (lymphocyte-to-HDL-c) may be a new indicator of inflammation and metabolic syndrome. Here, we investigated the associations of the lymphocyte-to-HDL-c with traditional and non-traditional cardiometabolic risk markers in subjects at high cardiovascular risk. This study is a cross-sectional analysis with subjects assisted in a Secondary Health Care (n = 581, age = 63.06 ± 13.86 years; 52.3% women). Lymphocyte-to-HDL-c ratio were assessed by routine laboratory tests. Anthropometric and/or biochemical variables were used to calculate traditional (body mass index - BMI, and waist-to-height ratio - WHtR) and non-traditional (lipid accumulation product index-LAP, visceral adiposity index-VAI, deep-abdominal-adipose-tissue index-DAAT, atherogenic index of plasma-AIP, and waist-hypertriglyceridemic phenotype-HTGW) cardiometabolic risk markers. Furthermore, anthropometric measurement waist circumference (WC), blood pressure, metabolic syndrome (MS), and biochemical markers (lipid and glycemic profile) were considered traditional markers of cardiometabolic risk. Pearson's chi-square test, Poisson regression with robust variance, or multinomial logistic regression were performed (α = 0.05). Individuals with a high lymphocyte-HDL-c ratio (> 0.84, 3rd tertile) were associated with the HTGW phenotype, high VAI, high LAP, hypertriglyceridemia, high AIP, high very low-density lipoprotein-cholesterol (VLDL-c), pre-diabetes, and 3 and 4 MS components compared with individuals in the first tertile, independent of confounders. Our findings supported the lymphocyte-to-HDL-c ratio as a potential biomarker during the screening of subjects at high cardiovascular risk.
RESUMO
Objective: To map the temporal evolution of overweight and obesity in Brazilian adults and estimate the prevalence of obesity for 2025 and 2030, evaluating the potential impact of the COVID-19 pandemic. Method: Data were collected on the nutritional status of adults from 2008 to 2021 from the Food and Nutrition Surveillance System (SISVAN), from which we calculated the prevalence and average annual rates of the variation of overweight and obesity. The projection of obesity, using linear regression, was analyzed in three scenarios: PP: with data from the pre-pandemic period (2008-2019); outlier: with adjustment of the data trend (2008-2021), including the pandemic period, considering a return of scenario PP for projections from 2022; P: adjustment of pandemic data (2019-2021) to estimate the projection. Result: In the period 20082021, we observed an average annual rate of overweight increase of 0.48 %/year. The prevalence of obesity more than doubled during this period, from 14.5% in 2008 to 32.9% in 2021 (i.e., an increase of 1.42). In the outlier scenario, the prevalence projections for obesity are 38.8% and 45.5% for 2015 and 2030, respectively. In the PP scenario (without the pandemic), the expected prevalence for the same period would be approximately 36.8% and 43.4%, respectively. Conclusion: Obesity and overweight follow an increasing trend. The COVID-19 pandemic accelerated the increase in the prevalence of obesity in Brazil and impacted its projections for the coming years
Objetivo: Mapear a evolução temporal de sobrepeso e obesidade de adultos brasileiros e estimar as prevalências de obesidade para 2025 e 2030, avaliando o potencial impacto da pandemia de COVID-19. Método: Foram coletados dados do estado nutricional de adultos de 2008 a 2021 do Sistema de Vigilância Alimentar e Nutricional (SISVAN), a partir dos quais foram calculadas as prevalências e taxas médias anuais da variação de sobrepeso e obesidade. A projeção da obesidade, utilizando regressão linear, foi analisada em três cenários: PP: com dados do período pré-pandemia (2008-2019); outlier: com ajuste da endência de dados (2008-2021), incluindo o período da pandemia, considerando um retorno do cenário PP para projeções a partir de 2022; P: ajuste dos dados da pandemia (2019-2021) para estimativa da projeção. Resultado: No período de 2008 e 2021, observamos uma taxa anual média de aumento de sobrepeso de 0,48 %/ano. A prevalência de obesidade mais que dobrou nesse período, passando de 14,5% em 2008 para 32,9% em 2021 (i.e., um aumento de 1,42). No cenário outlier, as projeções das prevalências de obesidade são de 38,8% e 45,5% para os anos de 2015 e 2030, respectivamente. No cenário PP (sem a pandemia), a prevalência esperada para o mesmo período estaria em torno de 36,8% e 43,4%, respectivamente. Conclusão: A obesidade e o sobrepeso seguem uma tendência de aumento crescente. A pandemia de COVID-19 acelerou o aumento da prevalência de obesidade no Brasil e impactou a sua projeção para os próximos anos.

Background: Most people recover from COVID-19, however, between 5 to 20% have experienced new, recurring, or continuous health problems four or more weeks after being infected, a phenomenon called Long COVID, and whose reasons for its manifestation are incipient. Our objective was to analyse the risk and protective factors for Long COVID in Brazilian adults participating in the CUME Study. Methods: The CUME Study is a prospective cohort conducted with graduates from federal universities in the State of Minas Gerais, Brazil. In this study, 390 participants who answered the baseline questionnaire in 2016 and the third follow-up questionnaire in 2022 (which contained a block of questions about occurrence of COVID-19 and Long COVID) were included. The diagnosis of Long COVID was based on self-reporting of persistence of signs and symptoms of COVID-19 between 30 days and 6 months after remission of the disease. To estimate the risk and protective factors for Long COVID, a hierarchical multivariate statistical analysis was conducted using the Poisson regression technique. Results: Long COVID was observed in 48.9% of the participants. The following characteristics were identified as risk factors for the outcome: female sex (RR = 1.56; 95% CI = 1.22-1.99); prior diagnosis of hypertension (RR = 1.46; 95% CI = 1.19-1.80); having contracted COVID-19 in the first (RR =1.38; 95% CI = 1.07-1.79) or in the second waves (RR = 1.33; 95% CI = 1.07-1.65) of the pandemic period; and having presented three or more signs and symptoms during the acute phase of COVID-19 (RR = 2.99; 95% CI = 1.08-8.24). On the other hand, having a doctoral/postdoctoral educational level (RR = 0.69; 95% CI = 0.50-0.94) was identified as a protective factor for the outcome. Conclusion: Health system managers and healthcare professionals should be aware of the socioeconomic profile and disease history of patients who have had COVID-19 because women, people with a prior diagnosis of hypertension, and those who manifested multiple signs and symptoms of COVID-19 during the acute phase of the disease were at greater risk of developing Long COVID.
RESUMO
ABSTRACT Objective Evaluate the food consumption of the participants of the Cohort of Universities of Minas Gerais, according to the degree of processing, and its relationship with socioeconomic, behavioral, and individual factors. Methods A total of 4,124 individuals from the baseline of the Cohort of Universities of Minas Gerais (2016 and 2018) participated in this study. Food consumption was self-reported by completing an online Food Frequency Questionnaire. The foods were divided into 3 groups: Group 1, in natura, minimally processed foods, culinary ingredients and culinary preparations; Group 2, processed foods; Group 3, ultra-processed foods. A hierarchical multiple linear regression model was used to verify the associated factors. Results Regarding the factors associated with food consumption, it is noteworthy that Group 1 was positively associated with the practice of physical activity, female gender, age, "non-white" skin color, and the presence of diabetes Mellitus; and negatively with "not married/without stable union" marital status, alcohol abuse, tobacco use, obesity, and depression. Considering Group 2, it was positively associated with alcohol abuse, tobacco use, and age; and negatively with physical activity, female gender, and "non-white" skin color. As for Group 3 it was positively associated with a marital status of "not married/without stable union", obesity, and depression; and negatively with physical activity, age, "non-white" skin color, and presence of diabetes Mellitus. Conclusion The factors that are in at least one of the final hierarchical linear regression models stand out: marital status, physical activity, alcohol abuse, tobacco use, sex, age, skin color, obesity, diabetes mellitus, and depression.

BACKGROUND: Dietary fatty acids are related to the development of several inflammatory-related diseases, which may include depression. So, the association between fatty acids, culinary oils and fat intake and depression in highly educated Brazilians was evaluated. METHODS: Multicenter cross-sectional study using baseline data from the Cohort of Universities of Minas Gerais. The diagnosis of depression was self-reported, and the daily intake of fatty acids was assessed using a 144-item food frequency questionnaire (FFQ). RESULTS: A total of 7157 participants (68.83 % women) with a median age of 33 years were included. The prevalence of depression was 12.60 % (N = 902). In the adjusted analyses, it was observed that individuals with the highest intake of omega-6 fatty acids (n-6) (OR: 1.36, 95 % CI 1.11-1.67) had a higher prevalence of depression. This increased n-6 intake was identified as a risk factor for depression only among male participants, while among overweight participants, higher n-6 intake was also positively associated with depression. Conversely, a higher ratio of polyunsaturated to monounsaturated and saturated fatty acids (PM/S) was also found to be positively associated with depression, but this association was observed only among non-overweight participants. No associations were found between the consumption of culinary oils or fats and depression. LIMITATIONS: Cross-sectional design limits the assessment of causality. The use of the FFQ can make estimates more difficult. CONCLUSION: Higher consumption of n-6, and higher PM/S ratios were associated with depression, and individual factors can interfere. The mental health care policies should include specific nutritional strategies.

OBJECTIVE: Estimate the incidence of the 30-year high cardiovascular risk and its determinants among graduates of federal universities in Minas Gerais. METHODS: This is a prospective cohort of 2,854 adults aged 20 to 59. The incidence of the outcome was calculated using the Framingham equation and its determinants were determined through multivariate Cox regression. RESULTS: After an average of 2.62 years, the incidence of high cardiovascular risk was 8.09 and 20.1 cases per 1,000 person-years, for females and males respectively. Being male (HR: 2.34; 95% CI: 1.58 - 3.46), employment (HR: 2.13; 95% CI: 1.13 - 3.99), high consumption of processed foods (HR: 2.44; 95% CI: 1.21 - 4.90), and being physically active (HR: 0.63; 95% CI: 0.41 - 0.98) were associated with high cardiovascular risk. CONCLUSIONS: Among highly educated adults, being male, employment, and high consumption of processed foods are predictors of high cardiovascular risk, while being physically active acts as a protective factor.

Background: Worldwide obesity has a high prevalence, as well as carries a high risk of several chronic diseases, including hypertension. Studies of the association between obesity and ambulatory blood pressure (BP) are scarce and most use only body mass index (BMI) as indicator of adiposity. Thus, we aimed to examine for associations between total and central adiposity and ambulatory BP parameters (BP means and variability, nocturnal dipping and morning surge) among participants in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Methods: This cross-sectional study (2012-2014) used a subsample of participants (n = 812) of ELSA-Brasil who underwent 24-hour ambulatory BP monitoring to assess systolic and diastolic BP (SBP and DBP, respectively) over 24-hour periods and sub-periods. Indicators for total adiposity were BMI and body fat (BF) and, for central adiposity, waist circumference (WC) and waist-to-height ratio (WHR). Associations were tested using crude and adjusted gamma and logistic regression. Results: Overweight (BMI) and abdominal obesity (WC and WHR) associated positively with mean 24-hour (Coef = 2.71, 3.09 and 4.00, respectively), waking (Coef = 2.87, 3.26 and 4.16, respectively), and sleeping (Coef = 2.30, 2.74 and 3.50, respectively) SBP; mean DBP associated with high WHR in these three periods (Coef = 2.00, 2.10 and 1.68, respectively) and with WC in the waking period (Coef = 1.44). Overweight and abdominal obesity (WC and WHR) were positively associated with SBP variability over 24â h (Coef = 0.53, 0.45 and 0.49, respectively) and in sleep (Coef = 0.80, 0.74 and 0.59, respectively), and with DBP variability in 24â h (Coef = 0.64, 0.73 and 0.58, respectively), wakefulness (Coef = 0.50, 0.52 and 0.52, respectively) and sleep (Coef = 0.53, 0.45 and 0.49); excess BF associated positively with DBP variability over 24â h (Coef = 0.43) and in wakefulness (Coef = 0.38). Lastly, high WHR and excess BF were associated with higher odds of extreme dipping (OR = 1.03 for both), while high WC and WHR associated with higher odds of exacerbated diastolic morning surge (OR = 3.18 and 3.66, respectively). Conclusion: Indicators of adiposity were associated with the BP means and variability, nocturnal dipping and morning surge, with more substantial results for indicators of central adiposity that the others.
RESUMO
The objective of this study was to identify and discuss the tools for the promotion and evaluation of adequate and healthy eating based on the Food Guide for the Brazilian Population. The scoping review was conducted according to the JBI Manual for Evidence Synthesis via the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist and by searching PubMed/MEDLINE, EMBASE, SciELO and LILACS. Sixteen studies on relevant tools, based on the food guide for individuals of all age groups, were thus included: two descriptive studies, two randomized clinical trial protocols, eleven methodological analyses, and one psychometric paper, aimed at either a focal population (n=12) or health professionals (n=4). Six studies addressed tools for promoting adequate and healthy eating, and ten developed tools for evaluating dietary practices or the knowledge and activities of health professionals. This review can therefore assist health professionals in choosing instruments for the implementation and/or dissemination of food guide recommendations, contributing to the promotion of adequate and healthy eating habits.

RESUMO
We aimed to evaluate the association between caffeine intake and sleep time in Brazilian adults. This cross-sectional study was conducted with 6,356 participants from the Cohort of Universities of Minas Gerais (CUME Study). Data was collected through an online self-report questionnaire. Of the total, 31.9% of the participants had insufficient sleep. Women were found to sleep less than men (64.1 vs. 35.9%; p < 0.001), as well as being more likely to consume higher doses of caffeine (55.2%, p < 0.001). Coffee (35.7%), dark chocolate (25.2%), milk chocolate (15.2%), and diet soda (11.0%) were the foods that more contributed to caffeine intake. Individuals in the highest quartile of caffeine intake (87.0 - 572.0 mg/day) had a 19% higher prevalence of insufficient sleep compared with the lowest quartile (PR: 1.19; 95%CI: 1.08 - 1.31). Future studies are needed to investigate the genetic and hormonal factors involved in the interindividual response in this population.
RESUMO
We aimed to analyze the different trajectories of 30-year cardiovascular risk (CVR) and its independently associated factors in participants of the CUME Study, a prospective study with alumni from federal universities of Minas Gerais State, Brazil. In this study, 1,286 participants who answered the baseline (2016) and follow-up (2018 and 2020) questionnaires were included. Trajectories of CVR, according to the Framingham score, were identified with the latent class growth modelling technique with the use of the censored normal model. Analysis of the factors independently associated with each of the trajectories was conducted with multinomial logistic regression technique. Three CVR trajectories were identified: Low-Low (68.3%), Medium-Medium (26.2%), and High-High (5.5%). Male sex, living in a stable union, and having moderate and high intakes of ultra-processed foods were positively associated with the Medium-Medium and High-High CVR trajectories. Having non-healthcare professional training and working were positively associated with the Medium-Medium CVR trajectory, whereas being physically active was negatively associated with the High-High CVR trajectory. In conclusion, more than one-third of participants had CVR trajectories in the Medium-Medium and High-High categories. Food consumption and physical activity are modifiable factors that were associated with these trajectories; thus, implementing health promotion measures could help prevent the persistence or worsen of CVR. On the other hand, sociodemographic and labor characteristics are non-modifiable factors that were associated with Medium-Medium and High-High trajectories, which could help identify people who should be monitored with more caution by health services.

Nuts are important sources of antioxidants that combat oxidative stress and improve lipid profile as well as vascular function. However, the intake of typical Brazilian nuts and its acute effect on cardiovascular health needs to be better understood. Thus, the present study aimed to evaluate the acute effect of a beverage containing cashew (Anacardium occidentale L.) and Brazil nuts (Bertholletia excelsa H.B.K.) on postprandial oxidative stress, lipemia, and blood pressure of adult women aged 20 to 55 years with cardiometabolic risk. This was an acute, randomized, parallel arm, controlled clinical trial. The participants received either a beverage containing nuts (30 g Brazil nuts + 15 g cashew nuts) or a beverage without nuts with similar macronutrient composition. Oxidative stress markers and lipid profiles were evaluated at fasting and 4 h after beverage consumption. Blood pressure was measured during fasting and after beverage intake (1, 2, 3, and 4 h). In the postprandial state, there was a greater reduction in malondialdehyde levels in the intervention group compared to the control group (-12.3 ± 0.59 vs. -10.7 ± 0.43 µmol/mL; p < 0.05), which was positively correlated with the concentrations of TG (r = 0.399; p < 0.05), VLDL (r = 0.399; p < 0.05), TG/HDL (r = 0.380; p < 0.05), and blood pressure (iAUC SBP r = 0.391; p < 0.05, iAUC DBP r = 0.409; p < 0.05). The remaining oxidative stress markers showed similar postprandial changes between groups. In women with cardiometabolic risk, a beverage containing Brazilian nuts promoted a significant acute reduction on postprandial malondialdehyde levels. The study was registered in the Brazilian Clinical Trials Registry-ReBEC (protocol: RBR-3ntxrm).

BACKGROUND AND AIMS: Ambulatory blood pressure monitoring (ABPM) allows the assessment of cardiovascular risk markers that cannot be obtained by casual measurements; however, the evidence on the association between food consumption and blood pressure (BP) assessed by ABPM is scarce. We aimed to evaluate the association between food consumption by degree of processing and ambulatory BP. METHODS AND RESULTS: Cross-sectional analysis (2012-2014) of data from a subsample (n = 815) of ELSA-Brasil cohort participants who performed 24-h ABPM was conducted. Systolic (SBP) and diastolic (DBP) BP means and variability during the 24 h and subperiods (sleep and wake), nocturnal dipping, and morning surge were evaluated. Food consumption was classified according to NOVA. Associations were tested by generalized linear models. The consumption of unprocessed, minimally processed foods, and culinary ingredients (U/MPF&CI) was 63.1% of daily caloric intake, 10.8% of processed (PF), and 24.8% of ultraprocessed (UPF). A negative association was found between U/MPF&CI consumption and extreme dipping (T2: odds ratio [OR] = 0.56, 95% confidence interval [CI] = 0.55-0.58; T3: OR = 0.55; 95% CI = 0.54-0.57); and between UPF consumption and nondipping (T2: OR = 0.68, 95% CI = 0.55-0.85) and extreme dipping (T2: OR = 0.63, 95% CI = 0.61-0.65; T3: OR = 0.95, 95% CI = 0.91-0.99). There was a positive association between PF consumption and extreme dipping (T2: OR = 1.22, 95% CI = 1.18-1.27; T3: OR = 1.34, 95% CI = 1.29-1.39) and sleep SBP variability (T3: Coef = 0.56, 95% CI = 0.03-1.10). CONCLUSIONS: The high consumption of PF was associated with greater BP variability and extreme dipping, while the U/MPF&CI and UPF consumption were negatively associated with alterations in nocturnal dipping.

We aimed to evaluate the intake of dietary total polyphenols and their classes according to NOVA classification among adults of a Brazilian cohort study. This is a cross-sectional study, in which food consumption was assessed using an Food Frequency Questionnaire (FFQ) and polyphenol content (total and their classes) was estimated at Phenol-Explorer for each food category and presented as mean and 95% confidence interval. Adjusted linear regression was used to describe the trend of the association between the quintiles of polyphenols intake (dependent variable) and NOVA group of food consumption (independent variable). The higher consumption of fresh/minimally processed foods is accompanied by a higher intake of total polyphenols and all their classes, while the higher consumption of ultra-processed foods represented the lower intake of total polyphenols and their classes. Fresh foods are the greatest sources of polyphenols, and their daily consumption should be encouraged, while ultra-processed foods are deficient in such bioactive compounds.

This study aims to evaluate the association between Dietary Total Antioxidant Capacity (dTAC) and Total Antioxidant Capacity of food groups (fgTAC) with the incidence of depression in Brazilian graduates participating in the Cohort of Universities of Minas Gerais (CUME Study). The sample consisted of 2572 participants without a medical diagnosis of depression at baseline who responded to at least one follow-up questionnaire from the CUME Project. The Ferric Reducing Antioxidant Power assay was used to determine dTAC. Incidence of depression was estimated by self-reported medical diagnosis of depression during the years of cohort follow-up. Cox regression models were used to relate dTAC and fgTAC to the incidence of depression. The mean follow-up time was 2·96 (1·00) years, and 246 cases of depression were observed (32·3/1000 person-years). The mean dTAC was 11·03 (4·84) mmol/d. We found no associations between higher dTAC and lower risk of developing depression after adjusting for possible confounders. The incidence of depression was inversely associated with fgTAC of the beans and lentils group (hazard ratio (HR): 0·61; 95 % CI 0·41, 0·90). The fgTAC of the junk food group was positively associated with higher incidence of depression after all adjustments (HR: 1·57; 95 % CI 1·08, 2·26). Our findings do not support an association between dTAC and the incidence of depression in a highly educated Brazilian population. However, associations of fgTAC show the importance of analysing the food matrix in which these antioxidants are inserted. We highlight the need for more prospective studies with different nationalities to confirm these results.

OBJECTIVE: To evaluate the association between the consumption of ultra-processed food and the incidence of depression in Brazilian adults. METHODS: This longitudinal study included 2572 participants (M = 936 and F = 1636, mean age of 36.1 years) from the Cohort of Universities of Minas Gerais - CUME Project, Brazil. Ultra-processed food (UPF) consumption (in % of daily energy intake, DEI), as defined by the NOVA food classification system, was assessed at baseline using a validated semi-quantitative 144-item food frequency questionnaire. Participants were classified as incident cases of depression if they reported a medical diagnosis of depression in at least one of the follow-up questionnaires. Crude and adjusted cox regression models were used to assess the relationship between UPF consumption and the incidence of depression. RESULTS: After a mean of follow-up of 2,96 years, a total of 246 incident cases of depression were identified. The mean consumption of UPF was 44 g/d or 24 % of DEI. Participants in the highest quartile of UPF consumption (31 to 72 % of DEI) had a higher risk of developing depression (HR = 1.82 95 % CI = 1.15-2.88) than those in the lowest quartile (0 to 16 % of DEI) after adjusting for potential confounders. CONCLUSION: Higher UPF consumption is a risk factor of depression incidence in Brazilian adults with high education level.
