These results indicate that yacon root flour is a potential diet supplement with high in vivo antioxidant activity. These data led us to believe that visceral fat may be a target of yacon effects. Advances in Experimental Medicine and Biology.

Transit time was assessed by a radio-opaque marker technique. The experimental animals invesgigaciones randomly divided into two groups: Food intakes were recorded daily as follows: Further studies are needed in constipated patients to confirm these preliminary data.

Triglycerides and total cholesterol concentrations were determined by enzymatic colorimetric methods using available commercial kits Wiener lab Group, Argentina.

Plant, Soil dl Environment. The high content of nondigestible fermentable fibers present in yacon roots as FOS together with phenolic compounds could be largely responsible for the beneficial effects observed.

The cellular and molecular bases of leptin and ghrelin resistance in obesity. National Center for Biotechnology InformationU. Biochemical parameters were determined in liver, kidney, and blood at the end of the experimental period. In agreement with this, Satoh et al. We wish to thank to Dr.

Effect of yacon (Smallanthus sonchifolius) on colonic transit time in healthy volunteers.

Reductions in cholesterol have only been found with long-term feeding of oligofructose in relatively high doses [ 60 ]. Therefore, the effect of yacon on modulating these adipokine levels in HFD rats was evaluated. Then, press proceed to send the authors a message. In the second approach, we determined that yacon supplementation potentiates the effects of the HFD reversion to a standard diet.


Current Protocols in Food Analytical Chemistry. At the cellular level, obesity is characterized by an increase in the number hyperplasia and size of individual adipocytes that have differentiated from preadipocyte in fat depots [ 5 ]. The high-density lipoprotein cholesterol HDLc was determined after precipitation of very low-density lipoprotein VLDL and low-density lipoprotein LDLc with polyanions dextran sulphate investigaicones magnesium chloride.

Figure S1 Supplementary materials shows the serum triglyceride values of the different experimental groups after oral oil loading. Morphometric and Nutritional Determinations Animals were weighed g yqcon throughout the experimental period. This means the journal and Pontificia Universidad Javeriana cannot be held responsible for any ethical malpractice by the authors.

A surface response methodology was use to evaluate the product optimization. Vaz-Tostes Md, Viana M. Previous Article Next Article. Previous studies demonstrated that dietary yacon supplementation reduces postprandial serum triglycerides in normal rats, without toxicity or adverse nutritional effects [ 17 ]. In investigaciobes placebo-controlled, double-blind study yacon was administered to 16 healthy individuals 8 males, 8 females in a dose of 20 g daily equal to 6.

Animals were weighed g weekly throughout the experimental period. Yacon is a root crop which contains high amounts yaocn fructooligosaccharides FOS.

Epub Apr 8. In this sense, natural products provide a rich source for safe and effective therapeutic compounds with multiple mechanisms of action [ 1213 ]. Improvement of biochemical parameters in type 1 diabetic rats after the roots aqueous extract of yacon [ Smallanthus sonchifolius Poepp.


The aim of this research was to optimize the parameters for the vacuum impregnation of aloe vera into dried yacon Smallanthus sonchifolius Poepp.

The HFD group received a standard-based diet enriched with eatable lard and carbohydrates modified from [ 33 ] to induce obesity and hyperlipidemia. Others are allowed to quote, adapt, transform, auto-archive, republish, and create based on invetigaciones material, for any purpose even commercial onesprovided the authorship is duly acknowledged, a link to the original work is provided, and it is specified if changes have been made.

A number of studies have shown that the diet-induced obese animal models mimic human obesity more than other models such as genetic knockout mutants [ 31 ]. Role of the small intestine, colon and microbiota in determining the metabolic fate of polyphenols.

Effect of yacon (Smallanthus sonchifolius) on colonic transit time in healthy volunteers.

It has been reported that inulin-type fructans fermentation increase the production of the anorexigenic hormones glucagon-like peptide-1 GLP-1 and peptide YY PYY in rodents affecting the food intake and energy expenditure [ 4243 ].
