ABSTRACT The Provisional Measure 870/2019, which amended the Organic Law on Food and Nutrition Security and extinguished the Conselho Nacional de Segurança Alimentar e Nutricional (National Council for Food and Nutrition Security), has brought serious consequences to the Brazilian population, especially for the most vulnerable. This scientific note brings reflections on the trajectory of the Conselho Nacional de Segurança Alimentar e Nutricional, the repercussions of its extinction in the last year, and the project to dismantle social protection policies in Brazil, with serious consequences at a time when the country is going through a crisis in public health due to the Covid-19 pandemic. The absence of the Conselho Nacional de Segurança Alimentar e Nutricional and the weakening of the set of policies for Food and Nutritional Security has mobilized the civil society to defend the human rights to food, food sovereignty, and to democracy itself. The resistance of the different social movements in order to maintain the spaces of civil participation related to Food and Nutrition Security public policies are still going to be long and arduous, demanding the continued vocalization and strengthening of partnership networks within the different movements of the organized civil society. Finally, we highlight the urgent need for restoration of the National System of Food and Nutritional Security (Sistema Nacional de Segurança Alimentar e Nutricional) with all its instances, and of other social policies, so that the negative consequences of the pandemic are avoided or mitigated and the State complies with its obligations to guarantee the rights of the Brazilian population.

Abstract Objective Identify and discuss strategies for execution the National School Feeding Program by state administrations during the coronavirus disease pandemic 2019. Methods This is a descriptive cross-sectional investigation. An exploratory review of the official publication of state governments and the Federal District to find out the strategies for the execution of the National School Feeding Program, after school closures due to the Covid-19 pandemic. Information on the form of execution and the public served by the action were reviewed in a descriptive manner. Results Out of the 27 federative units, 55% distributed food kits, 26% supplied food cards/vouchers and 19% provided food kits and food cards/vouchers. As to the scope, 37% maintained general service, 30% attended schoolchildren from families registered in the Brazilian cash transfer program (Bolsa Família) and 26% attended schoolchildren from families registered in the Underprivileged Families Registry. Conclusion The National School Feeding Program was weak in terms of assuring the Human Right to Adequate Food and Food and Nutrition Security. The slowness of the federal administration and the gaps in the regulations issued may explain the changes in the reported strategies, which, in their majority, violate the principle of universality.

Abstract Family farming plays a vital role in the global food supply. The mobility restriction measures adopted internationally to contain Covid-19 are necessary to control the pandemic progress. However, they can impair food production and distribution. This paper aims to discuss the effects of the Covid-19 containment measures on the production and distribution of family farming food, and strategies to strengthen this sector. Sanitary and social distancing requirements, the interruption of supply to institutional markets, the closure of local farmers’ markets, or people’s declining food demand are hampering family farming food production’s flow and shrinking family farmers’ income. This situation can jeopardize the food sovereignty and nutritional security of the population in the medium and long term. Access to Personal Protective Equipment, the reorganization of local farmers’ markets, investment in new technologies for direct commercialization, guarantee of minimum income, and the strengthening/expansion of institutional food purchases are some of the strategies that can contribute to overcome the new challenges imposed on family farming as a result of the Covid-19 pandemic. We conclude the article by arguing that the support to and enhancement of the family farming sector are strategic to ensure food supply and to strengthen food and nutrition sovereignty and security.

Abstract The current scenario generated by the Covid-19 pandemic enhances the condition of food and nutrition insecurity due to the worsening of poverty, hunger and lack of access to food, as well as the excess consumption of foods considered unhealthy. The effects of the pandemic enhances the need for a new way of arranging the production, distribution and consumption of food, giving new meaning to the relationship between food, eating and the environment. Thus, it is suggested that a reflection be made on the strategies for the appropriate healthy, adequate and sustainable diet in Brazil to face this health emergency. Actions must be focused on the articulation of strategies that foster sovereignty, food and nutrition security and healthier and more sustainable food systems such as the strengthening of family farming; income assurance for the population; access to quality food; changes in the food environment; dissemination of information on healthy and sustainable food in official recommendations for the pandemic and food guides covering the entire food system, as well as food and nutrition education practices.

ABSTRACT In Brazil, indigenous peoples present a complex reality characterized by a marked social vulnerability that is manifested in health and nutritional indicators. In this scenario, poor sanitary conditions prevail, with a high burden of chronic noncommunicable diseases; infectious/parasitic diseases; and nutritional disorders, including malnutrition and anemia. This situation is reflected in numerous aspects of food insecurity, placing this population in a position of particular vulnerability to the coronavirus disease 2019 pandemic and its effects. The objective of our study was to present a set of preliminary reflections on food insecurity and indigenous protagonism in times of Covid-19. The pandemic has deepened the inequalities that affect the indigenous peoples, with a direct impact on food security conditions. Amid the effects of the pandemic, indigenous protagonism has played a fundamental role in guaranteeing these peoples’ rights and access to food, denouncing the absent and slow official responses as acts of institutional violence, which will have serious and lasting effects on the lives of indigenous peoples.

ABSTRACT This article aims to present reflections on cooking skills in times of the coronavirus disease 2019 pandemic. The current period of uncertainty and isolation heightens food insecurity issues, influencing food choice, purchase, and preparation. Social media and networks are sources of entertainment and learning, with vast resources for cooking skills, which can stimulate home cooking and strengthen family ties. Research has evidenced the positive relationship between cooking and diet quality, an important factor for groups at increased risk of severe illness from Covid-19. For some individuals, cooking may be a strategy to reduce anxiety and stress associated with the pandemic. However, the Brazilian reality is marked by inequalities in income and access to food. Thus, more vulnerable populations may not have the same relationship with cooking. Public policies should focus on food and nutrition programs and actions for the development of cooking skills as a means to promote healthy eating and encourage self-care.

ABSTRACT Objective The objective of this work was to review papers that deal with nutritional therapy of inpatients with Covid-19 from the beginning of the pandemic. The survey covered the period until the month of September 2020. Methods This is a review of the indexed literature (Scopus, Pubmed and Lilacs), including area consensus. Results The review showed that the initial recommendations were based on generic assumptions and, as specific knowledge was being produced, the recommendations became more targeted. Conclusion In the health crisis generated by Covid-19, in the context of uncertainties related to nutritional care procedures, knowledge and action strategies were generated, coordinated by researchers and health professionals.

ABSTRACT Objective Acrylamide is a potentially neurotoxic and carcinogenic chemical and naturally creates during the heating process of carbohydrate-rich foods, such as potato chips and breakfast cereals. Acrylamide might be ingested by people via consuming food that contains it. Therefore, we investigated the effect of acrylamidegiven orally to male and female rats on plasma retinoic acid and α-tocopherol and serum sialic acid and malondialdehyde levels. Method A total of 50 Wistar rats were used (25 female and 25 male, three-four weeks old). The rats of each sex were given 2 and 5mg/kg/day acrylamide via drinking water for 90 days. At the end of the treatment, the animals were euthanized by cervical dislocation. Blood specimens were collected through cardiac puncture, and serum and plasma samples were analysed using the high-performance liquid chromatography technique with a Ultraviolet detector. Results The analysis of the plasma and serum samples revealed that serum sialic acid and malondialdehyde levels in both sexes given 5mg/kg/day acrylamide were significantly increased, and the serum sialic acid levels were higher in female rats given 2mg/kg/day acrylamide. The plasma retinoic acid and α-tocopherol levels significantly decreased in both sexes given only the highest dose. Conclusion The results show that acrylamide causes an increase in oxidative stress and leads to a decrease in the levels of retinoic acid and α-tocopherol which play a role in the defense mechanism against this stress.

ABSTRACT Objective This study was conducted with 370 undergraduate students to investigate the relationship between food intake, food addiction and disordered eating behavior. Methods The Yale Food Addiction Scale, Eating Attitude Test-26 and Food Frequency Questionnaire were used to assess food addiction, disordered eating behavior and food intake. Results A positive weak correlation was found between the Yale Food Addiction Scale and daily energy, carbohydrate and fat intake (r=0.228, p<0.001; r=0.222, p<0.001; r=0.225, p<0.001 respectively) whereas a negative weak correlation was found between Eating Attitude Test-26 and daily energy and carbohydrate intake (r=-0.105, p=0.044; r=-0.116, p=0.025 respectively). Conclusion Food intake is associated with food addiction and disordered eating behaviour. Further research should be conducted with a larger population also examining body composition, exercises and financial situation of the individuals because all of these factors have an influence on the nutritional status and eating behavior as well.

ABSTRACT Objective To investigate the consumption of processed and ultra-processed foods and evaluate its relationship with the nutritional and metabolic status of hemodialysis patients in a single center in Brazil. Methods This cross-sectional study enrolled 73 individuals in hemodialysis (50 men and 23 women, 21-87 years-old). Clinical and lifestyle variables were assessed by a semi-structured questionnaire and dietary data by food frequency questionnaire. Anthropometric and metabolic data are collected from medical records. Results Processed and ultra-processed foods represented 11.0% of daily caloric intake, 53.0% of trans fatty acid, and 12.5% of salt consumed in the study sample. Individuals who had high intake of this food group (≥128.4g/day, median intake) had higher serum phosphorus and pre-dialysis urea values (p=0.038; p=0.013, respectively). Also, individual with higher consumption of processed meat, sausages and ready prepared food had higher pre-dialysis serum urea (p=0.021), while serum potassium was higher among the subjects who consumed more sauces and salt-based seasonings (p=0.002). Conclusion Higher consumption of processed and ultra-processed foods was associated with important biomarkers of metabolic control for hemodialysis subjects, probably due to non-health dietary composition. Nutritional guidelines and intervention strategies must be promoted to reduce consumption of these food-group in thisspecific population.

ABSTRACT Objective To evaluate the agreement between the modified version of the Nutritional Risk in the Critically Ill Score (without Interleukin-6) and a variant composed of C-Reactive Protein as well as its capacity to predict mortality. Methods A prospective cohort study was carried out with 315 patients in an Intensive Care Unit of a university hospital from October 2017 to April 2018. The agreement between the instruments was evaluated using the Kappa test. The predictive capacity for estimating mortality was assessed with the Receiver Operating Characteristic curve. Results The critical patients involved in the study had a mean age of 60.8±16.3 years and 53.5% were female. Most patients had C-Reactive Protein levels ?10mg/dL (n=263, 83.5%) and their admission in the Intensive Care Unit was medical (n=219, 69.5%). The prevalence of mortality was observed in 41.0% of the evaluated patients. The proportions at high nutritional risk according to Nutritional Risk in the Critically Ill without Interleukin-6 and with C-Reactive Protein were 57.5% and 55.6%, respectively. The tools showed strong and significant agreement(Kappa=0.935; p=0.020) and satisfactory performances in predicting mortality (area under the curve 0.695 [0.636-0.754] and 0.699 [0.640-0.758]). Conclusion Both versions of the Nutritional Risk in the Critically Ill tool show a satisfactory agreement and performance as predictors of mortality in critically ill patients. Further analysis of this variant and the association between nutrition adequacy and mortality is needed.

ABSTRACT Objective To evaluate the effects of macronutrients (protein, carbohydrate and/or lipid) in the diet of young adult (72 days) and adult (182 days) Wistar rats treated ad libitum and with 30% restriction from birth on anxiety in the elevated plus-maze. Methods We used 238 rats treated from birth, composing the groups: Control, Protein, Carbohydrate, Lipid, Carbohydrate and Lipid, Control Restriction, Protein Restriction, Carbohydrate Restriction, Lipid Restriction and Carbohydrate and Lipid Restriction. The animals were weighed at the beginning and at the end of the experiment and tested in the elevated plus-maze. Data were submitted to analysis of variance, followed by the Newman-Keuls Test (p<0.05). Results Among the animals treated ad libitum, the Control, Carbohydrate plus Lipid and Lipid gained more weight than the Carbohydrate and Protein; ad libitum animals gained more weight than those on restriction; among the restrictions, Carbohydrate Restriction rats were the ones that gained less weight. Diet-restricted animals exhibited reduced first-entry latency, greater percentage of entries and time spent, frequency of open arm extremity visits, head dipping (protected and unprotected), and length of stay in the central area of the elevated plus-maze. The animals with 182 days presented greater latency for first entry, reduced frequency of false entries and visits to the ends of the open arms and protected head dipping. Conclusion Food restricted animals, regardless of the macronutrient present in the diet, were less anxious and/or increased their impulsivity and those at 182 days were more anxious and/or with reduced impulsivity.

ABSTRACT Objective To examine the changes in the nutritional status of adolescents aged 10-19 years after a minimum 12 months interval following oncological treatment for leukemias and lymphomas. Methods Longitudinal design quantitative study conducted at Hospital de Clínicas, Porto Alegre. Adolescents aged 10-19 years after a minimum 12 months interval following oncological treatment for leukemias and lymphomas were included. The measures of weight, height, brachial circumference, triceps skinfold thickness, arm muscle circumference and abdominal circumference were collected. Results The sample comprised 50 adolescents who had survived leukemias and lymphomas. In the follow up 38% of the patients were classified as overweight according to the body mass index for their age. There was a significant increase in body mass index for age between the beginning and the end of treatment and follow up (p=0.013) in female individuals, compared to males. The results indicate a reduction in the Z-score means of height for age, with significant differences between the beginning of treatment and follow up (p=0.016); and end of treatment and follow up (p=0.006) in patients of both genders Conclusion The anthropometric indicators show an important frequency of excess weight and increased tricipital skinfold, as well as a significant increase of the body mass index for age and also a growth deficit among the survivors.

ABSTRACT Objective In this paper, we studied three different types of ordinary sports supplements containing whey protein: whey protein-based ones, hypercaloric ones, and protein bars. Methods A sample preparation procedure was studied employing microwave-assisted wet digestion in order to determine the Chromium and Manganese levels by graphite furnace atomic absorption spectrometry. Results The developed methods have presented good accuracy (recoveries in the range of 90% to 109%) and precision (Relative standard deviation <8%). Although an adequate detectability was obtained (50ng g-1 for Manganese and 65ng g-1 for Chromium), the sample preparation method was also adequate to inductively coupled plasma mass spectrometry analysis. The method was applied to 26 commercial samples, in which the Chromium concentrations were in the range between 0.22 and 1.0μg g-1 and the Manganese concentrations varied from 2.0 to 37μg g-1. Conclusion The results obtained by atomic absorption for both analytes were in agreement with those obtained by mass spectrometry. In addition, some samples presented concentrations of Chromium above the recommended daily intake and, as a result, we used the X-ray powder diffraction technique as an analytical tool to evaluate the oxidation state of Chromium in such samples.

ABSTRACT Objective The purpose of this study is to determine the phenolic and flavonoid contents, and antioxidant activities and neuroprotective effects of powdered coffee sample of a commercial coffee brand originated from Sivas, Turkey. Methods Total phenolic, flavonoid and antioxidant contents, enzymatic and non-enzymatic antioxidative activities based on 2,2-diphenyl-1-picrylhydrazyl free radical scavenging activity, metal chelating potential, reducing power, superoxide dismutase and catalase activity tests and lipid peroxidation inhibition potentials of the ethanolic and aqueous extracts of the coffee sample were assayed using the commonly preferred spectrophotometric methods. Furthermore the extracts’ cholinesterase and tyrosinase inhibition potentials were evaluated. Phenolic profiles of the coffee sample were investigated using high performance liquid chromatography. Results Catechin was the most frequently detected phenolic acid. In addition, it was demonstrated that the water extract has a significant impact when compared with standard antioxidants. While the SC50 (sufficient concentration to obtain 50% of a maximum scavenging capacity) value for the scavenging activity of 2,2-diphenyl-1-picrylhydrazyl free radical was calculated as being 0.08mg/mL for water extract, the amount of chelating agents with half Fe2+ ions in the medium was found to be 0.271mg/mL. Additionally, it was shown that 0.1mg/mL concentration of both extracts prevents lipid peroxidation by 8%. Compared with standard drugs, inhibition potentials of cholinesterase and tyrosinase enzymes were considered as moderately acceptable in these samples. Conclusion Besides the extracts’ enzymatic antioxidant activity, their inhibition potential on cholinesterase and tyrosinase enzymes – which are important clinical enzymes – reveal that this natural source can be used as a valuable resource in different fields, especially in medicine.

ABSTRACT Objective To analyze and compare the sugar content in sugar sweetened beverages in Brazil and Portugal, according to the Pan American Health Organization nutritional profile model. Methods One hundred six equivalent sugary beverages were selected in the markets of São Paulo, Brazil and Porto, Portugal. Nutritional information reported on the labels was reviewed, according to the Pan American Health Organization nutritional profile model, regarding the critical content of free sugars, salt, total saturated fats and trans fatty acids. Results The Brazilian nectars presented higher amounts of sugar and vitamin C compared to Portuguese nectars that contained more protein. The juices in Portugal contained a higher content of vitamin C and Portuguese dairy beverages had higher levels of protein and sodium, while the Brazilian ones had more total fats. According to the critical nutrients proposed by the Pan American Health Organization, Brazil had excess sodium in dairy beverages and soft drinks, while in Portugal excess sodium was found in nectars and dairy beverages. In both countries, excess free sugars were present in all beverages. Conclusion The amount of sugar in the beverages represents an important contribution of added sugar, especially in the Brazilian nectars. The identification of this component in sugary beverages is fundamental for the adoption of strategies of food education to control obesity.

ABSTRACT Objective The presence of dietary bioactive compounds in the human diet becomes a major factor in combating the etiology of different pathologies. Thus, the aim of this investigation was to evaluate the fatty acids profile, cardiovascular functionality indices, bioactive compounds and spectroscopic pattern of peach palm oil (pupunha oil) and their impact on human health. Methods The oil was obtained by soxhlet extraction; the oil yield and qualities were determined according to the standards of the Association of Official Analytical Chemists. For the fatty acids profile, the practical recommendations of the American Oil Chemists’ Society and of the International Organization for Standardization were followed. Total carotenoids and polyphenols were determined by spectrophotometry; the composition of the chemical groups was determined by infrared spectroscopy. The anti-atherogenic, antithrombogenic and hypocholesterolemic indices were obtained using mathematical models. Results The results showed good quality oil based on acid and peroxyde indices (2.45±0.33mg KOH g-1 and 5.47±1.05mEq kg-1). The main fruit bioactive compound was β-carotene (832.4±0.64µg/100g). The chromatographic profile showed a high saturated fatty acid content (53.74%); unsaturated (46.25%); fats were monounsaturated (39.66%) and polyunsaturated (6.59%). The antiatherogenic, antithrombogenic and hypocholesterolemic indices were, on average, 1.10, 2.04 and 0.84, respectively. The spectroscopic profile exhibited bands with variation from 2918.8cm-1 to 714cm-1. Conclusion The results indicate that the consumption of isolated lipid content of the pupunha palm oil provides health protection with emphasis on the prevention of cardiovascular diseases.

ABSTRACT Objective This study aimed to determine whether physical fitness is related to nutritional status in a sample of female adolescents with anorexia nervosa, to contrast the nourished and undernourished patients, and to compare the physical fitness in these patients with normative data of healthy subjects stratified by age and gender. Methods Nutritional status was determined using the body mass index Z-score, fat mass, fat-free mass (bioelectrical impedance analysis), and the Controlling Nutritional Status score in 15 anorexic adolescents with 14.3±1.6 years. Physical fitness was assessed using the ALPHA-Fitness Battery (handgrip strength, standing broad jump, 4x10m shuttle run, and 20m shuttle run tests). Results Handgrip strength was significantly associated with all variables of nutritional status, except with the three blood components of the Controlling Nutritional Status score. The undernourished anorexic patients showed significantly worse physical fitness than the nourished anorexic patients in all tests, except in the standing broad jump and the 4x10m shuttle run tests. The physical fitness tests of the female anorexic adolescents showed scores significantly worse than those of the normative European female adolescent population. Conclusion The observation of female adolescents with anorexia nervosa showed associations between higher physical fitness levels and better nutritional statuses. Handgrip strength and 20m shuttle run tests may be options of additional indicators of undernutrition in anorexic female adolescents. The undernourished anorexic patients showed worse physical fitness than the nourished ones. According to normative data for healthy sex- and agematched adolescents, physical fitness is severely impaired in anorexic female adolescents.

ABSTRACT Objective The study aimed to verify the relationship between handgrip strength measurement and classic anthropometric values in HIV positive outpatients. Methods This was a cross-sectional study that enrolled HIV-positive outpatients treated at the Gaffrée and Guinle University Hospital, aged between 20 and 60 years and considered to be well-nourished or moderately malnourished, according to the Global Subjective Analysis. The patients’ bilateral handgrip strength were assessed (Jamar dynamometer), and classic anthropometry variables (weight, height, body mass index, arm muscle area, arm fat area, arm muscle circumference, and triceps skin fold) were measured. The Kolmogorov-Smirnov test, t-test, bivariate correlation and regression analysis were used (SPSS 21® software), with a significance level of 5%. Results A total of 242 patients were assessed. According to the Global Subjective Analysis, 218 (90.1%) patients were classified as well nourished (Global Subjective Analysis-A) and 24 (9.9%) as moderately malnourished (Global Subjective Analysis-B). The average dominant hand handgrip strength with standard deviation was 30.5±9.5kgf and 24.1±6.1kgf for Global Subjective Analysis-A and Global Subjective Analysis-B patients, respectively. Handgrip values were not influenced by age. The handgrip strength showed in both genders a significant correlation with weight, body mass index, and with anthropometric parameters related to lean body mass (arm muscle circumference and arm muscle area), but without correlation with the non-lean mass parameter (arm fat area). The handgrip strength of the dominant hand was a predictor of the following variables associated with lean body mass, i.e., arm muscle circumference and arm muscle area (R2=0.194, t=7.7, p<0.001, and R2=0.192, t=7.6, p<0.001, respectively). However, handgrip strength was not a predictor of arm fat area. Conclusion Measurement of handgrip strength was a useful method for nutritional assessment in outpatients with HIV due to a significant relationship with anthropometric parameters associated with lean body mass.

ABSTRACT Objective This study aimed at examining whether food consumption varies in accordance with socio-demographic and behavioral factors in the conceptual model, analyzing adult women in Tehran, Iran, for that purpose. Methods This cross-sectional study was conducted with 247 women in childbearing age, who were selected through systematic cluster sampling from five regions in Tehran. Dietary assessment was done through a Food Frequency Questionnaire, and the anthropometric indices were measured. Data on socio-economic status and information-motivation-behavioral skills model were obtained through a questionnaire. Then, subjects were stratified according to the socio-economic status and model components. Statistical analysis was done using analysis of variance and structural equation modeling. Results Consumption of food groups among the participating women differed based on their living region, education, occupation, household expenditure, and model components (p<0.05). Intake of red and processed meat (p<0.05) was at the lowest level in illiterate or low educated women. Those with lower total expenditure had higher consumption of fats and oils (p<0.05). Women with higher perceived social support consumed more milk and dairy products (p<0.05), fats and oils (p<0.05), and less bread and cereals (p<0.05). Model components including information, attitude, social support, self-efficacy, and self-regulation were the most important factors negatively affecting the consumption of unhealthy foods (red and processed meat, fats and oils, sugar, and salty foods). Conclusion Considering the impact of model components on women’s eating behaviors, the specific integration strategies delineated for each construct of the model can be utilized to design model-based interventions targeting the promotion of healthy nutritional behavior.
