Antioxidant potential of acerola by-product along the enterohepatic axis of rats fed a high-fat diet.

Acerola (Malpighia emarginata DC) by-product (ABP) has bioactive compounds that can provide antioxidant and hypolipidemic effects in vivo. In this study we aimed to evaluate the antioxidant potential of ABP on oxidative damage along the enterohepatic axis of rats fed a high-fat diet for 7 weeks. In addition, we analysed the phenolic compound profile in the enterohepatic axis, and the lipid accumulation in the liver, colon and liver tissue structure of high-fat diet-fed rats treated with fenofibrate drug (100 mg/kg) or ABP (400 mg/kg) via orogastric administration in the 4th to 7th weeks of the experiment.

Ruminant fat intake improves gut microbiota, serum inflammatory parameter and fatty acid profile in tissues of Wistar rats.

This study tested the hypothesis that naturally and industrially produced trans-fatty acids can exert distinct effects on metabolic parameters and on gut microbiota of rats. Wistar rats were randomized into three groups according to the diet: CONT-control, with 5% soybean oil and normal amount of fat; HVF-20% of hydrogenated vegetable fat (industrial); and RUM-20% of ruminant fat (natural). After 53 days of treatment, serum biochemical markers, fatty acid composition of liver, heart and adipose tissue, histology and hepatic oxidative parameters, as well as gut microbiota composition were evaluated.

Mucuna pruriens treatment shows anti-obesity and intestinal health effects in obese rats.

This study evaluated the anti-obesity effect and intestinal health of obese rats treated with Mucuna pruriens (MP), focusing on food consumption and somatic, biochemical, and histological parameters. A total of 32 adult male Wistar rats were initially randomized into a healthy group (HG, n = 16) which consumed a control diet and an obese group (OG, n = 16) which consumed a cafeteria diet for eight weeks. They were then subdivided into four groups: healthy (HG, n = 8); healthy treated with MP (HGMP, n = 8); obese (OG, n = 8); obese treated with MP (OGMP, n = 8), with consumption of their respective diets continuing for another eight weeks; the treated groups received 750 mg kg of MP extract via gavage.

Vitamin D insufficiency/deficiency and its association with cardiometabolic risk factors in Brazilian adolescents.

Objective: this study aimed to investigate the association between serum 25-hydroxyvitamin D (25 [OH] D) and cardiometabolic risk factors in Brazilian adolescents. Methods: a cross-sectional study with 220 school adolescents aged 15 to 19 years was performed in the city of João Pessoa-PB, Brazil. The variables studied were: 25 hydroxyvitamin D (25 OH), dietary intake of vitamin D, anthropometric data (body mass index (BMI), waist circumference (WC) and waist / height ratio (RCA) and biochemistry, total cholesterol (TC), Low Density Lipoprotein (LDL), High Density Lipoproteins (HDL), triglyceride (TG), C-reactive protein (CRP), alpha acid glycoprotein (AGPA), malondialdehyde (MDA) and total antioxidant capacity (CAT), blood pressure, parathyroid hormone (PTH) and serum calcium.

Maternal dyslipidaemic diet induces sex-specific alterations in intestinal function and lipid metabolism in rat offspring.

This study investigated the effects of a maternal dyslipidaemic (DLP) diet on lipid metabolism, microbial counts in faeces and hepatic and intestinal morphology in rat offspring with respect to sex during different phases of life. Wistar rats (dams) were fed a control (CTL) or DLP during gestation and lactation. After weaning, CTL and DLP offspring were fed a standard diet.

Beneficial effects of consumption of acerola, cashew or guava processing by-products on intestinal health and lipid metabolism in dyslipidaemic female Wistar rats.

This study assessed the effects of diet supplementation with industrial processing by-products of acerola (Malpighia emarginata D.C.), cashew (Anacardium occidentale L.

Potential ergogenic activity of grape juice in runners.

Recent studies have indicated that certain food products have ergogenic potential similar to that of sports supplements. The present study aimed to investigate the potential ergogenic effect of integral purple grape juice on the performance of recreational runners. Twenty-eight volunteers of both sexes (age, 39.

Chia flour supplementation reduces blood pressure in hypertensive subjects.

The aim of this study was to investigate the effect of chia supplementation (Salvia hispanica L.) on blood pressure (BP) and its associated cardiometabolic factors in treated and untreated hypertensive individuals. The subjects were randomly assigned to one of the following groups: the hypertensive-drug treated (CHIA-MD, n = 10), hypertensive untreated (CHIA-NM, n = 9) and placebo (PLA-MD, n = 7) groups.

Chia induces clinically discrete weight loss and improves lipid profile only in altered previous values.

Introduction: chia (Salvia hispanica L.) has an elevated concentration of dietary fiber, it has been used to weight loss and enhance blood glucose and lipid profile. However, data in human are still scarce or do not exist, according to the analyzed variable.
