Bacillus probiotics health benefits have been until now quite poorly studied in the elderly population. This study aimed to assess the effects of Bacillus subtilis CU1 consumption on immune stimulation and resistance to common infectious disease (CID) episodes in healthy free-living seniors. One hundred subjects aged 60–74 were included in this randomized,(More)
BACKGROUND AND AIM Many mothers consult physicians because of frequent infant regurgitation. Guidelines recommend reassurance and dietary treatment as first approaches. The aim of the present study was to test and compare the efficacy of 2 antiregurgitation formulae (ARF). METHODS A prospective, double-blind, randomized cross-over trial was performed for(More)
PURPOSE To determine the effect of 4 weeks of supplementation, then, withdrawal of a dietary supplement (DS) containing red yeast rice extract, policosanol and artichoke leaf extract at twice the recommended daily dose (6 tablets, 6-TAB) compared to the usual dose (3-TAB) or to a placebo (PLA), on blood lipid profiles and safety biomarkers. METHODS(More)
During postprandial state, TG concentration is increasing and HDL cholesterol decreasing, leading to a transitory pro-atherosclerotic profile. Previous studies have reported that bicarbonate water improve postprandial lipemia. The objective of this study was to analyze the effect of a strongly bicarbonated mineral water on lipoprotein levels during fasting(More)
The impact of the daily consumption of 15 g chicory native inulin on fecal levels of bifidobacteria, stool parameters and quality of life of elderly constipated volunteers was investigated in a randomized, double-blind, controlled versus placebo clinical trial. The impact of supplementation on constipation was assessed with questionnaires on bowel motor(More)
OBJECTIVE To investigate the effect of a natural cholesterol-lowering supplement (NCLS) containing red yeast rice, policosanols and artichoke leaf extracts on blood lipid concentrations as well as on safety parameters when given over 16 weeks in 100 volunteers with untreated moderate hypercholesterolemia, in a randomized, double-blind, placebo-controlled(More)
BACKGROUND/OBJECTIVES An imbalance between Th1 and Th2 cells is involved in allergic rhinitis (AR) that may be improved by probiotics. To test the efficacy of the probiotic Lactobacillus paracasei subsp. paracasei LP-33, a double-blind, placebo-controlled, randomized trial was carried out in patients with AR to grass pollen treated with loratadine and(More)
SCOPE Silicon (Si) is an abundant element on earth. It is found naturally in water in the form of orthosilicic acid (OSA), however this form is not stable under certain conditions such as in highly concentrated and non-neutral pH solutions, which lead to its polymerization and reduced bioavailability. This study aimed to assess the bioavailability of Si(More)
BACKGROUND To assess consumers' acceptance of a new fibre, it is essential to evaluate its digestive tolerance after ingestion. We aimed to determine the tolerance of increasing dosages of Promitor™ Soluble Gluco Fibre (SGF; Tate&Lyle, Hoffman Estates, IL, USA) up to 70 g fibre per day using a validated gastrointestinal composite score. METHODS A(More)
BACKGROUND/OBJECTIVE To determine gastrointestinal (GI) responses and maximum tolerated dose of erythritol in young children given as a single oral dose in a 250-ml non-carbonated fruit-flavoured beverage in between meals. This is a multicentre double-blind study with sequential design for multiple dose groups and randomised crossover for comparators of(More)
