Recently, increased attention has been paid to the link between gut microbial composition and obesity. Gut microbiota is a source of endotoxins whose increase in plasma is related to obesity and insulin resistance through increased intestinal permeability in animal models; however, this relationship still needs to be confirmed in humans. That intestinal(More)
SCFA provide energy to the host and influence lipid and glucose metabolism, suggesting that they may have an impact on the occurrence of metabolic risk factors. The aim of the present study was to determine the concentration of SCFA in faeces of lean and obese individuals and to analyse whether associations between faecal SCFA and metabolic syndrome(More)
BACKGROUND & AIMS Altered intestinal permeability has been shown to be associated with metabolic alterations in animal models of obesity, but not in humans. The aim of this study was to assess intestinal permeability in obese women and verify if there is any association with anthropometric measurements, body composition or biochemical variables. METHODS(More)
Food fortification is an efficient strategy applied to overcome iron deficiency anemia. This study investigated the effect of iron fortification with probiotic bacteria in a milk beverage on growth and iron status of preschool children with a usually low-bioavailable-iron diet intake. The fermented milk beverage was fortified with iron amino acid chelate (3(More)
Gut colonisation with bifidobacteria in early infancy is essential for the well-being of the infant. Gestational age and mode of delivery are among the factors influencing the colonisation process. The aim was to characterise the bifidobacterial composition in the gut of one-month-old full-term and pre-term Brazilian infants, both being delivered vaginally(More)
Numerous Lactobacillus species are members of the normal healthy human intestinal microbiota, and members of the Lactobacillus family predominate among the current marketed probiotic strains. Most of the current commercial probiotic strains have not been selected for specific applications but rather have been chosen based on their technological properties.(More)
UNLABELLED Studies have shown fibers to be effective in reducing the appearance of aberrant crypt foci (ACF) in rodents. OBJECTIVE The goal of this study was to investigate the preventive effects of fructooligosaccharide (FOS) and inulin prebiotics on the appearance of ACF in mice. MATERIALS AND METHODS The techniques used were: RT-PCR to evaluate the(More)
There is growing evidence that kefir can be a promising tool in decreasing the risk of many diseases, including metabolic syndrome (MetS). The aim of the present study was to evaluate the effect of kefir supplementation in the diet of Spontaneously Hypertensive Rats (SHR) in which MetS was induced with monosodium glutamate (MSG), and to determine its effect(More)
OBJECTIVE The goal of this study was to investigate the preventive effects of defatted flaxseed meal on the appearance of aberrant crypt foci (ACF) in mice treated with 1,2-dimethylhydrazine (DMH). MATERIALS AND METHODS ACF were induced by intraperitoneal administration of 20 mg/kg body weight of DMH for 8 weeks. The animals were divided into three(More)
