Highlights of three metabolites HDL and reduction in blood pressure values after dietary fiber supplementation in overweight and obese normotensive women: a metabolomic study.

INTRODUCTION: The prevalence of hypertension and obesity are a worldwide concern. OBJETIVES: Assess the metabolites profile after intervention with mixed dietary fiber in overweight and obese normotensive women. METHODS: This is a randomized double blind placebo-controlled study. Through a simple randomization process, two groups were allocated, with eleven women (group 1) receiving 12 g of mixed dietary fiber and thirteen women (group 2) receiving 12 g of placebo (corn starch) for eight weeks. Anthropometric and biochemical tests and lifestyle were analyzed. As for evaluation metabolomics, used a 1H NMR. The data matrix generated 96 samples and 225 variables, which was exported in the ASCII format for the "The Unscrumbler" statistics software (version 9.7, CAMO Process). RESULTS: After the intervention with mixed dietary fiber, significant differences were observed between the main types of metabolites, referring to the increase in the relative peak areas of in three HDL metabolites 4.94 ppm (0.0086*), HDL 1.28 ppm (0 .0337*), HDL 0.88 ppm (0.0224*) and an α-glucose metabolite 4.90 ppm (0.0106) and the reduction in systolic blood pressure (SBP) (0.0292*) of 7 mmHg in the reference range and in the placebo group there was a reduction in SBP (0.0118*) of 4 mmHg and of a choline metabolite 3.65 ppm (0.0266*), which does not call into question the validity of these results in the literature. CONCLUSION: The synergism of the functions of these statistically highlighted metabolites contributed to prevention the increase in SBP after fiber intervention in overweight and obese normotensive women.

Methylation profile of the ADRB3 gene and its association with lipid profile and nutritional status in adults.

BACKGROUND: Defects in DNA methylation have been shown to be associated with metabolic diseases such as obesity, dyslipidemia, and hypercholesterolemia. To analyze the methylation profile of the ADRB3 gene and correlate it with lipid profile, lipid intake, and oxidative stress based on malondialdehyde (MDA) and total antioxidant capacity (TAC), homocysteine and folic acid levels, nutritional status, lifestyle, and socioeconomic variables in an adult population. A cross-sectional epidemiological study representative of the East and West regions of the municipality of João Pessoa, Paraíba state, Brazil, enrolled 265 adults of both genders. Demographic, lifestyle, and socioeconomic questionnaires and a 24-h recall questionnaire were applied by trained interviewers' home. Nutritional and biochemical evaluation (DNA methylation, lipid profile, MDA, TAC, homocysteine and folic acid levels) was performed. RESULTS: DNA hypermethylation of the ADRB3 gene, analyzed in leukocytes, was present in 50% of subjects and was associated with a higher risk of being overweight (OR 3.28; p = 0.008) or obese (OR 3.06; p = 0.017), a higher waist-hip ratio in males (OR 1.17; p = 0.000), greater intake of trans fats (OR 1.94; p = 0.032), higher LDL (OR 2.64; p = 0.003) and triglycerides (OR 1.81; p = 0.031), and higher folic acid levels (OR 1.85; p = 0.022). CONCLUSIONS: These results suggest that epigenetic changes in the ADRB3 gene locus may explain the development of obesity and non-communicable diseases associated with trans-fat intake, altered lipid profile, and elevated folic acid. Because of its persistence, DNA methylation may have an impact in adults, in association with the development of non-communicable diseases. This study is the first population-based study of the ADRB3 gene, and the data further support evaluation of ADRB3 DNA methylation as an effective biomarker.

Decrease of the DNA methylation levels of the ADRB3 gene in leukocytes is related with serum folate in eutrophic adults.

BACKGROUND: DNA methylation has been evidenced as a potential epigenetic mechanism related to various candidate genes to development of obesity. Therefore, the objective of this study was to evaluate the DNA methylation levels of the ADRB3 gene by body mass index (BMI) in a representative adult population, besides characterizing this population as to the lipid profile, oxidative stress and food intake. METHODS: This was a cross-sectional population-based study, involving 262 adults aged 20-59 years, of both genders, representative of the East and West regions of the municipality of João Pessoa, Paraíba state, Brazil, in that were evaluated lifestyle variables and performed nutritional, biochemical evaluation and DNA methylation levels of the ADRB3 gene using high resolution melting method. The relationship between the study variables was performed using analyses of variance and multiple regression models. All results were obtained using the software R, 3.3.2. RESULTS: From the stratification of categories BMI, was observed a difference in the average variables values of age, waist-to-height ratio, waist-to-hip ratio, waist circumference, triglycerides and intake of trans fat, which occurred more frequently between the categories "eutrophic" and "obesity". From the multiple regression analysis in the group of eutrophic adults, it was observed a negative relationship between methylation levels of the ADRB3 gene with serum levels of folic acid. However, no significant relation was observed among lipid profile, oxidative stress and food intake in individuals distributed in the three categories of BMI. CONCLUSIONS: A negative relationship was demonstrated between methylation levels of the ADRB3 gene in eutrophic adults individuals with serum levels of folic acid, as well as with the independent gender of BMI, however, was not observed relation with lipid profile, oxidative stress and variables of food intake. Regarding the absence of relationship with methylation levels of the ADRB3 gene in the categories of overweight, mild and moderate obesity, the answer probably lies in the insufficient amount of body fat to initiate inflammatory processes and oxidative stress with a direct impact on methylation levels, what is differently is found most of the times in exacerbated levels in severe obesity.

Influence of the C677T Polymorphism of the MTHFR Gene on Oxidative Stress in Women With Overweight or Obesity: Response to a Dietary Folate Intervention.

The C677T polymorphism of the methylenetetrahydrofolate reductase gene (MTHFR) is related to folate metabolism and can alter the levels of biochemical markers.Objective: Investigate the influence of the MTHFR C677T polymorphism on the effects of a dietary folate intervention on oxidative stress in women with overweight or obesity.Methods: Forty-eight adult women with overweight or obesity were subjected to a 24-hour dietary recall, anthropometric measurements, biochemical analysis, and genotyping of the MTHFR C677T polymorphism. They were allocated by convenience sampling to 2 groups, which received 300 g of folate-rich vegetables containing 191 µg/d (Group 1) (n = 24) or 95 µg/d (Group 2) (n = 24) of folate for 8 weeks.Results: The dietary intervention increased the serum folic acid levels in the 2 analyzed groups. The intervention with 191 µg/d of folate led to relevant results in terms of homocysteine levels (p = 0.0005) and total antioxidant capacity (p = 0.0261); the effect was larger among carriers of the TT genotype.Conclusions: The study demonstrated the beneficial effect of folate intake in terms of a TAC elevation for the CC and TT genotypes of the MTHFR C677T polymorphism, an increase in folic acid levels for all genotypes, and a reduction in the Hcy levels for the TT genotype in response to an intervention consisting of an intake of 191 µg/d of folate supplied by vegetables.

Choline Metabolites, Hydroxybutyrate and HDL after Dietary Fiber Supplementation in Overweight/Obese Hypertensive Women: A Metabolomic Study.

Metabolomics has been increasingly used to evaluate metabolic changes associated with morbidities. The objective of this study is to assess the metabolic profile before and after intervention with mixed dietary fiber in overweight and obese hypertensive women. This is an intervention study, and the sample consists of 14 women aged 28 to 58 years. An intervention with 12 g of mixed soluble and insoluble fiber is performed for a period of eight weeks. Serum metabolites are identified using a Bruker 1H NMR spectrometer at 400 MHz. Multivariate data analysis, including principal component analysis (PCA), is used to differentiate the two groups. After supplementation with dietary fiber, there is a significant increase in the peak intensity values of the metabolites HDL-C (0.0010*), choline (0.0012*) and hydroxybutyrate (0.0010*) as well as a decrease in systolic (0.0013*) and diastolic (0.0026*) blood pressure. The analysis of the metabolomic profile allows the identification of metabolites that have been associated in the literature with hypertension and excess weight (choline, hydroxybutyrate and amino acids) and with fiber intake (choline, hydroxybutyrate and amino acids) in addition to an increase in HDL-C. The increase in the detection of the described metabolites possibly occurs due to the presence of pathologies and the use of fiber in the intervention, which also contributes to elevated HDL-c and reduced blood pressure.

Food Intervention with Folate Reduces TNF-α and Interleukin Levels in Overweight and Obese Women with the MTHFR C677T Polymorphism: A Randomized Trial.

Methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism associated with body fat accumulation could possibly trigger an inflammatory process by elevating homocysteine levels and increasing cytokine production, causing several diseases. This study aimed to evaluate the effects of food intervention, and not folate supplements, on the levels of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1ß (IL-1ß) in overweight and obese women with the MTHFR C677T polymorphism. A randomized, double-blind eight-week clinical trial of 48 overweight and obese women was conducted. Participants were randomly assigned into two groups. They received 300 g of vegetables daily for eight weeks containing different doses of folate: 95 µg/day for Group 1 and 191 µg/day for Group 2. MTHFR C677T polymorphism genotyping was assessed by digestion with HinfI enzyme and on 12% polyacrylamide gels. Anthropometric measurements, 24-h dietary recall, and biochemical analysis (blood folic acid, vitamin B12, homocysteine (Hcy), TNF-α, IL-1ß, and IL-6) were determined at the beginning and end of the study. Group 2 had a significant increase in folate intake (p < 0.001) and plasma folic acid (p < 0.05) for individuals with the cytosine-cytosine (CC), cytosine-thymine (CT), and thymine-thymine (TT) genotypes. However, only individuals with the TT genotype presented reduced levels of Hcy, TNF-α, IL-6, and IL-1ß (p < 0.001). Group 1 showed significant differences in folate consumption (p < 0.001) and folic acid levels (p < 0.05) for individuals with the CT and TT genotypes. Food intervention with folate from vegetables increased folic acid levels and reduced interleukins, TNF-α, and Hcy levels, mainly for individuals with the TT genotype.

α-Tocopherol influences glycaemic control and miR-9-3 DNA methylation in overweight and obese women under an energy-restricted diet: a randomized, double-blind, exploratory, controlled clinical trial.

BACKGROUND: Excess weight is a strong risk factor for the development of dysglycaemia. It has been suggested that changes in the metabolism microRNAs, small non-coding RNAs that regulate gene expression, could precede late glycaemic changes. Vitamin E in turn may exert important functions in methylation and gene expression processes. This study aimed to determine the effect of α-tocopherol on glycaemic variables and miR-9-1 and miR-9-3 promoter DNA methylation in overweight women. METHODS: A randomized, double-blind, exploratory, placebo-controlled study was conducted in overweight and obese adult women (n = 44) who ingested synthetic vitamin E (all-rac-α-tocopherol), natural source vitamin E (RRR-rac-α-tocopherol) or placebo capsules and were followed up for a period of 8 weeks. Supplemented groups also received dietary guidance for an energy-restricted diet. An additional group that received no supplementation and did not follow an energy-restricted diet was also followed up. The intervention effect was evaluated by DNA methylation levels (quantitative real-time PCR assay) and anthropometric and biochemical variables (fasting plasma glucose, haemoglobin A1C, insulin, and vitamin E). RESULTS: Increased methylation levels of the miR-9-3 promoter region (P < 0.001) and reduced haemoglobin A1C (P < 0.05) were observed in the natural source vitamin E group after intervention. Increased fasting plasma glucose was observed in the synthetic vitamin E group, despite the significant reduction of anthropometric variables compared to the other groups. CONCLUSIONS: α-Tocopherol from natural sources increased methylation levels of the miR-9-3 promoter region and reduced haemoglobin A1C in overweight women following an energy-restricted diet. These results provide novel information about the influence of vitamin E on DNA methylation. TRIAL REGISTRATION: ClinicalTrials.gov, NCT02922491. Registered 4 October, 2016.

Hypermethylation in the promoter of the MTHFR gene is associated with diabetic complications and biochemical indicators.

BACKGROUND: DNA methylation is an epigenetic mechanism for regulating the transcription of many genes and has been linked to the development of various diseases. A promising gene to investigate is methylenetetrahydrofolate reductase (MTHFR), since the enzyme methylenetetrahydrofolate reductase (MTHFR) promotes methyl radical synthesis in the homocysteine cycle and can provide methyl groups for DNA methylation. In addition, several studies have correlated gene polymorphisms of this enzyme with a greater risk of diabetes, but little is known regarding the relationship between epigenetic changes in this gene and diabetes and its complications. The aim of this study was to investigate the relationship between methylation profile in the MTHFR gene promoter and biochemical, inflammatory and oxidative stress markers in individuals with type 2 diabetes (T2DM) who have been diagnosed for 5-10 years with or without diabetic retinopathy (DR) and nephropathy (DN). METHODS: Specific PCR for methylation (MSP) was used to analyze MTHFR methylation profile in leucocytes DNA. Biochemical markers (glycemia, glycated hemoglobin, total cholesterol, LDL, HDL, triglycerides, serum creatinine), inflammatory markers (C-reactive protein and alpha-1 acid glycoprotein) and oxidative stress (total antioxidant and malonaldehyde) were determined in peripheric blood samples and microalbuminuria in 24 h urine samples. The X2 and Mann-Whitney statistical tests were performed and p < 0.05 were considered significant. RESULTS: The hypermethylated profile was most frequently observed in individuals with retinopathy (p < 0.01) and was associated with higher total cholesterol and LDL levels (p = 0.0046, 0.0267, respectively). Individuals with DN and hypermethylated profiles had higher levels of alpha-1 acid glycoprotein (p = 0.0080) and total antioxidant capacity (p = 0.0169) compared to subjects without complications. CONCLUSIONS: Hypermethylation in the promoter of the MTHFR gene is associated with the occurrence of DR and with biochemical, inflammatory and oxidative stress parameters in the context of chronic complications.

Effect of a diet containing folate and hazelnut oil capsule on the methylation level of the ADRB3 gene, lipid profile and oxidative stress in overweight or obese women.

BACKGROUND: Studies of genes that play an important role in the development of obesity are needed, especially studies focusing on genes that regulate food intake and affect nutrient metabolism. For example, the beta-3 adrenergic receptor (ADRB3) responds to noradrenaline and mediates lipolysis in adipocytes. METHODS: This was a controlled intervention study involving 40 overweight and obese adult women in which food intake, anthropometric measurements, biochemical analyses, and methylation levels of the ADRB3 gene were evaluated before and after intervention. The individuals were randomized into four groups: group 1 (G1) received 300 g of vegetables and legumes containing on average 191 µg/day of folate and 1 hazelnut oil capsule; group 2 (G2) received 300 g of vegetables and legumes containing on average 191 µg/day of folate and 1 placebo capsule; group 3 (G3) received 300 g of vegetables and legumes containing on average 90 µg/day of folate and 1 hazelnut oil capsule; and individuals in group 4 (G4) were only followed-up and maintained their regular dietary habits. Statistical analysis was performed using analysis of variance (ANOVA), Student's t test and simple regression, using STATA 13 software. RESULTS: In the total sample, after the intervention, the women classified as overweight and obese did not present weight loss, and there was a reduction in the methylation levels of the ADRB3 gene and malondialdehyde, as well as an increase in high-density lipoprotein cholesterol and total antioxidant capacity. CONCLUSIONS: The beneficial effect of the intake of a hazelnut capsule on the methylation levels of the ADRB3 gene was demonstrated for the first time.

Existe Relação Entre Níveis de Retinol Sérico, Ingestão de Fibra e Proteína C-Reativa Ultra-Sensível Em Idosos Hipertensos? / Is There A Relationship Between Serum Retinol Levels, Fiber Intake And High-Sensitivity C-Reactive Protein In Hypertensive Elderlies?

Objetivo: O objetivo deste estudo foi investigar a associação do retinol sérico, proteína C-reativa ultra-sensível (PCR-us) e a ingestão de fibras alimentares em uma população de idosos hipertensos. Material e Métodos: Trata-se de um estudo transversal de base populacional com 170 idosos com idade entre 60 e 90 anos, de ambos os sexos, de uma cidade do Nordeste do Brasil. Para as análises bioquímicas, as concentrações de retinol sérico e PCR-us foram analisadas e um questionário quantitativo de frequência de alimentar auto-administrado foi coletado. Foram utilizados como critérios de inclusão: idosos de 60 a 90 anos que residiam na cidade de João Pessoa e hipertensão auto-relatada. Os critérios de exclusão foram indivíduos com transtornos neuropsiquiátricos e indivíduos que relataram suplementação de vitamina A, carotenóides ou suplementos de fibras. Os dados foram analisados com o teste de Wilcoxon, teste exato de Fisher e análise de regressão logística. Todas as análises estatísticas foram realizadas com o Software R Development Core Team. Resultados: Não foram observadas relações significativas entre hipertensão arterial e níveis séricos de retinol (p = 0,4325), níveis de PCR (p = 0,4104) e consumo de fibra alimentar (p = 0,0935). Com base na regressão logística, cada aumento de 1 unidade no índice de massa corporal (IMC) aumenta a probabilidade de hipertensão em 0,009545%. As outras variáveis não contribuíram para o modelo de regressão final. Conclusão: Considerando a alta prevalência de indivíduos hipertensos com valores adequados de retinol, não houve associação entre retinol sérico, níveis de PCR e ingestão de fibra. A maioria dos participantes apresentou níveis normais de PCR-us, que podem ter sido influenciados pela atividade antioxidante do retinol e pela ingestão inadequada de fibras. (AU)

Objective: To investigate the association between serum retinol, highlsensitivityC- reactive protein (hs-CRP) and dietary fiber intake in a population of hypertensive elderlies. Material and Methods: This was a cross-sectional population-based study with170 elderly people aged 60-90 years, of both sexes, from a city in northeastern Brazil. Biochemical analyses were performed, in which serum retinol and hs- CRP concentrations were analyzed, and a self-administered quantitative food frequency questionnaire was applied. Inclusion criteria were: 60-90 years old, living in the city of Joao Pessoa, and selfreported hypertension. Exclusion criteria were: individuals with neuropsychiatric disorders, and individuals who reported supplementation of vitamin A, carotenoids or fiber supplements. The data were analyzed using Wilcoxon test, Fisher's exact test and logistic regression analysis. All statistical analyses were performed with the R Development Core Team Software. Results: No significant relationships were observed between hypertension and serum retinol levels (p = 0.4325), hs-CRP levels (p = 0.4104) and dietary fiber intake (p = 0.0935). Based on logistic regression, each 1 unit increase in body mass index (BMI) increases the probability of hypertension by 0.009545%. The other variables did not contribute to the final regression model. Conclusion: Considering the high prevalence of hypertensive individuals with adequate retinolvalues, there was no association between serum retinol, CRP levels and fiber intake. The majority of participants had normal hs-CRP levels, which may have been influenced by the antioxidant activity of retinol and inadequate fiber intake. (AU)

Baixo consumo habitual de alimentos fonte de vitamina E em população infantil / Low habitual consumption of food sources of vitamin E in the child population

Este estudo avaliou o consumo alimentar habitual de vitamina E em crianças do município de João Pessoa, Nordeste-Brasil. Estudo epidemiológico transversal, de base populacional, representativo do referido município foi realizado em 170 crianças de idade entre 2 e 10 anos. Foram coletados os dados antropométricos e do consumo alimentar por meio de Questionário Quantitativo de Frequência Alimentar, previamente validado para a população desse município. O consumo de vitamina E foi avaliado pelo software Dietsys 3.0. Observou-se maior frequência de crianças com peso adequado (59,4), seguido de 20 com obesidade e 13 com sobrepeso. Houve maior frequência de crianças com consumo de vitamina E abaixo da necessidade média estimada (62,4). As crianças que apresentaram ingestão adequada de vitamina E consumiram mais iogurte, tortas e bolos, e aquelas com o inadequado consumiram mais margarina. Na amostra total, os produtos fonte de vitamina E mais consumidos foram iogurte, waffles, tortas, bolos, batatas fritas, óleos e margarina. Conclui-se que >50 das crianças analisadas apresentam baixo consumo de vitamina E, sendo necessária a implementação de estratégias para aumentar a disponibilidade de alimentos menos calóricos, considerando-se a elevada prevalência de obesidade e sobrepeso observada, e mais ricos em vitamina E para essa população.
