“…Beans and meat are sources of zinc, what may explain the proper consumption of this mineral by adolescents 25 . In a study by Retondário et al 26 , also with data from ERICA, meat, pasta, poultry and fish were the foods that contributed the most to the amount of selenium consumed by this group.…”

The study aims to evaluate the association between inadequate consumption of antioxidant minerals and plasma lipoprotein concentrations in adolescents. We conducted a cross-sectional study that evaluated sociodemographic and anthropometric data, information on intake of magnesium, selenium and zinc and lipid profile. Student's t-test was used to compare means between the groups and logistic regression to verify the strength of the association between the independent variables and lipid profile. Inadequate zinc consumption was associated with a higher chance of low HDL-c levels and lower chance of hypertriglyceridemia and high LDL-c levels. Inadequate selenium intake was associated with a lower chance of high total cholesterol and of high triglyceride concentrations and a higher chance of low HDL-c levels. Inadequate magnesium consumption was associated with a higher chance of high cholesterol and triglyceride levels, a lower chance of high LDL-c levels and with a higher chance of low HDL-c. We observed an association between inadequate consumption of magnesium, zinc and selenium and changes in the lipid profile of adolescents.

“…Known natural sources of dietary Se are mushrooms, Brazil nuts, broccoli, cereals, breads, millets, wheat, nuts and meats (61) , but Se levels depend on soil composition (62) . An investigation involving more than 70 000 Brazilian adolescents found that the main dietary sources of Se for this age group were meat, pasta, poultry and fish (58) , probably because of their dietary habits.…”

“…Daily median Se intake was higher than dietary recommendations (13) . A study developed with the ERICA database found an adequate Se intake among adolescents by applying the EAR (Estimated Average Requirement) cut off method, although differences between sexes and age groups were found (58) . In this way, for Brazilian adolescents, the Se intake values found in this study seem to be sufficient to meet their nutritional needs.…”

Selenium acts reducing cellular inflammation and lipid peroxides; therefore, its association with cardiovascular diseases and metabolic syndrome (MetS) has been studied. We aimed to investigate the association between selenium intake and MetS/its parameters (high waist circumference, hyperglycemia, high blood pressure, high triglycerides, and low HDL-c) in Brazilian adolescents between 12-17 years old. This research is part of the Study of Cardiovascular Risks in Adolescents (ERICA), a Brazilian nationwide school-based study with regional and national relevance. We assessed: 1) socio-demographic data (sex, age, type of school, and maternal education) using a self-administered questionnaire; 2) dietary intake using a 24h recall applied for the whole sample and a second one applied to a subsample to allow within-person variability adjustment; 3) anthropometric data (weight, height, waist circumference) and blood pressure using standardized procedures; 4) biochemical analyses (fasting glucose, triglycerides, and HDL-c). Logistic regression was applied, basing the analysis on a theoretical model. Median Se intake was 98.3µg/day. Hypertension and hyperglycemia were more prevalent among boys, while a high waist circumference was more frequent in girls, and low HDL-c levels were higher among private school students. The prevalence of MetS was 2.6%. No association between MetS/its parameters and Se intake was found. This lack of association could be due to an adequate Se intake in the studied population.

“…A large study conducted with Brazilian adolescents (12-17 years of age) from all areas of the country showed the prevalence of selenium adequacy in terms of intake, with most selenium being acquired from meat, poultry, and products derived from wheat [85]. Intake of UPFs was correlated with inadequate selenium intake in adolescents from the northeastern region of Brazil [86].…”

Intersection between Obesity, Dietary Selenium, and Statin Therapy in Brazil

Obesity is among the most alarming health concerns, impacting public health and causing a socioeconomic challenge, especially in developing countries like Brazil, where approximately one quart of the population presents obesity. As an established risk factor for numerous comorbidities with a multifactorial etiology, obesity is a consequence of energy-dense overfeeding, however with significant undernourishment, leading to excessive adipose tissue accumulation and dysfunction, dyslipidemia, and micronutrient deficiencies. About 60% of patients with obesity take statins, a cholesterol-lowering medication, to curb dyslipidemia, with ~10% of these patients presenting various myopathies as side effects. Statins act upon the rate-limiting enzyme of cholesterol biosynthesis in the liver, which is a pathway providing intermediates to the synthesis of selenoproteins, i.e., enzymes containing the micronutrient selenium. Statins have been postulated to negatively impact selenoprotein synthesis, particularly in conditions of selenium deficiency, and potentially implicated in the myopathies occurring as side effects of statins. The Brazilian population is prone to selenium deficiency, hence could be considered more susceptible to statin side effects. This review examines the specific consequences to the Brazilian population of the harmful intersection between obesity development and concomitant micronutrient deficiencies, particularly selenium, combined with statin treatment in the context of nutrition in Brazil.
