“…These results are in agreement with Pierce et al (2005Pierce et al ( , 2006 and Hoebler et al (2000). It is postulated that inulin supports lactic acid bacteria such as bifidobacteria and lactobacilli (Tako et al, 2007).…”

The effects of inulin and alginate on intestinal microbial ecophysiology were investigated in piglets fed a diet (C) with 0.1% alginate (C+A) or 1.5% inulin (C+I) from weaning at day 28. The experiment was performed at an experimental farm (EF) and a commercial farm (CF). Digesta was collected from the ileum, caecum and colon of four piglets from each group on days 29, 30, 33 and 39. The metabolite concentrations changed with age. Colonic and caecal metabolites were affected by prebiotic treatment. Changes in microbiota composition were assessed by cultivation and denaturing gradient gel electrophoresis (DGGE) of 16S rRNA gene fragments. Enterococci increased in C+A at EF and decreased in C+I at both farms. Lactobacilli decreased in all segments in the experimental groups on days 30 and 33. Yeasts in C+I were five times lower at CF than at EF on day 39. The richness and diversity of DGGE profiles increased in the experimental groups. The evenness of colon digesta-derived DGGE profiles was higher in the experimental groups than in C and this situation was reversed in the distal small intestine. Multivariate redundancy analysis confirmed the recorded effects. In summary, both prebiotics affected the intestinal microbiota, and the changes were more pronounced at the CF.

“…This was accompanied by a higher amount of the ingested starch (50%) left in the small intestine in the alginate group. In support of this, a highly viscous alginate increased viscosity of the ileal digesta 3.5-fold in pigs (40). In dogs fed with a liquid formula enriched with alginate (with added calcium), the rate of starch digestion or glucose absorption was reduced such that concentrations of serum glucose were maintained without affecting serum insulin concentrations (75).…”

“…Additionally, a lower non-starch polysaccharide (NSP) digestibility was observed with the increasing dietary alginate concentration, which could be an indicator of an overall reduced energy utilization (39). Furthermore, a high-viscosity alginate (5%) was found to increase (3.5-fold) the viscosity of the content of the small intestine and slow nutrient absorption in pigs (40). However, some evidence suggests that water-soluble fibres with low M w in general only exhibit limited inhibitory effect on nutrient absorption and health benefits beyond their effects on colonic health (41).…”

“…Although the effect of alginate supplementation on fermentation and caecal short-chain fatty acid (SCFA) concentration is still inconclusive (39), a highly viscous alginate (5%) diet led to a significant increase in SCFA concentration in pigs compared to a cellulose-enriched control diet (40). SCFAs have been suggested to be mechanistically involved in the release of the anorexic gut peptides, glucagon-like peptide-1 (GLP-1) and peptide YY (PYY) from L-cells in the intestine (42)(43)(44).…”

Review: efficacy of alginate supplementation in relation to appetite regulation and metabolic risk factors: evidence from animal and human studies

et al. 2012

This review provides a critical update on human and animal studies investigating the effect of alginate supplementation on appetite regulation, glycaemic and insulinemic responses, and lipid metabolism with discussion of the evidence on potential mechanisms, efficacy and tolerability. Dependent on vehicle applied for alginate supplementation, the majority of animal and human studies suggest that alginate consumption does suppress satiety and to some extent energy intake. Only one long-term intervention trial found effects on weight loss. In addition, alginates seem to exhibit beneficial influence on postprandial glucose absorption and insulin response in animals and humans. However, alginate supplementation was only found to have cholesterol-lowering properties in animals. Several mechanisms have been suggested for the positive effect observed, which involve delayed gastric emptying, increased viscosity of digesta and slowed nutrient absorption in the small intestine upon alginate gel formation. Despite reasonable efficacy and tolerability from the acute or short-term studies, we still realize there is a critical need for development of optimal alginate types and vehicles as well as studies on further long-term investigation on alginate supplementation in humans before inferring that it could be useful in the management of obesity and the metabolic syndrome.

“…Since seaweed is very light in dry weight and swells greatly when rehydrated during digestion, it has also been reported that seaweed intake increases stool weights and decreases colon transit time [14,25]. In addition, seaweed has been reported to affect the metabolic activities of intestinal microflora [14,15].…”
