Earlier studies have indicated a decrease in anaerobes and bifidobacteria and a concomitant increase in enterobacteria in the intestinal microbiota with ageing. However, new data obtained with molecular techniques suggests decreased stability and increased diversity of the gut microbiota with advancing age. Further, no simple marker change in microbiota(More)
Polydextrose (Litesse®, DuPont) is a polysaccharide that is partially fermented in the colon. Evidence suggests that polydextrose increases satiety when consumed over several weeks; however studies assessing its acute effects on satiety are lacking. This study therefore aimed to assess the impact of different doses of polydextrose on satiety and energy(More)
Ageing has been suggested to cause changes in the intestinal microbial community. In the present study, the microbiota of a previously well-defined group of elderly subjects aged between 70 and 85 years, both non-steroidal anti-inflammatory drugs (NSAID) users (n 9) and non-users (n 9), were further compared with young adults (n 14) with a mean age of 28(More)
BACKGROUND Dietary fibers are associated with enhanced satiety. However, the mechanism of different dietary fibers contributing to satiety-related gastrointestinal (GI) peptide release, especially in an obese population, is still poorly understood. Polydextrose (PDX), a water-soluble glucose polymer, has demonstrated its ability to reduce energy intake at a(More)
INTRODUCTION Dietary fibers help to control energy intake and reduce the risk of developing obesity. Recent studies show that the consumption of polydextrose reduces energy intake at a subsequent meal. In this systematic review and meta-analysis we examine the subsequent effects of polydextrose on different levels of energy intake (EI). METHOD The review(More)
Elderly individuals are more susceptible to gastrointestinal problems such as constipation than young adults. Furthermore, the common use of non-steroidal anti-inflammatory drugs (NSAID) among the elderly is known to further increase such gastrointestinal ailments. To describe the specific changes in elderly, intestinal microbes, their metabolites and(More)
INTRODUCTION Subjective feelings of appetite are measured using visual analogue scales (VAS) in controlled trials. However, the methods used to analyze VAS during the Satiation (pre- to post-meal) and Satiety (post-meal to subsequent meal) periods vary broadly, making it difficult to compare results amongst independent studies testing the same product. This(More)
Ageing changes gut microbiota composition and alters immune system function. Probiotics, prebiotics and synbiotics may improve the health status of elderly individuals by modifying the intestinal environment and the microbiota composition, and by stimulating the immune system. In this work, we studied the effects of synbiotic supplementation on the gut(More)
Obesity is characterised by a state of chronic low-grade inflammation and the elevated circulating and tissue levels of inflammatory markers, including inflammation-related adipokines, released from white adipose tissue. The expression and release of these adipokines generally rises as the adipose tissue expands and hypoxic conditions start to develop(More)
BACKGROUND Three independent trials were conducted to evaluate postprandial triglyceride (TG) responses in subjects with different lipid metabolism. The effect of polydextrose (PDX), a soluble non-digestible carbohydrate, on postprandial response was also studied using practically relevant, high fat meal interventions. METHODS A total of 19 normolipidemic(More)
