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 ]. No significant changes were observed for the spleen and pancreas in all the studied groups.

American Journal of Clinical Nutrition. Even more is investigated if the effects of yacon are modified by the type of diet consumed. The spilled food was weighed and dried after feces had been picked out.

Additionally, the presence chlorogenic and caffeic acid in yacon roots could also contribute to the hypolipidemic effect observed after yacon supplement [ 18 ]. Back to tab navigation. Alejandra Kortsarz for skilled technical assistance with FOS estimation. Additionally, yacon roots present strong antioxidant activity and anti-inflammatory effects preventing the risks associated knvestigaciones metabolic diseases [ 27 — 29 ].

It was investigacipnes that caffeic acid, particularly chlorogenic acid, improves lipid metabolism in high-fat-diet-induced obese mice [ 61 ]. The mean value of SD-fed rats was set at 1.

January – June Bioengineering and chemical engineering plugins. Role of the small intestine, colon and microbiota in determining the metabolic fate of polyphenols.

Thus, the improved inveestigaciones tolerance and insulin action in obese rats after yacon supplementation may lead us to suggest that this beneficial effect could be mediated by adipokines modulation as was suggested previously [ 54 ]. Gomes da Silva M.

Moreover, releasing GLP-1 from intestinal L-cells directly into the portal vein could also represent an additional mechanism related to yacon FOS-improved glucose homeostasis [ 55 ].

Yacon effects in immune response and nutritional status of iron and zinc in preschool children. Plasma cholesterol and triacylglycerol levels and liver fatty acid composition, which were altered in diabetic rats, reverted back to nearly normal with yacon treatment.

Thus, the identification of novel foods that promote satiety or reduce energy density provides an interesting tool in managing obesity and its associated comorbidities [ 613 ]. AP2; fatty acid synthase: Current Protocols in Food Analytical Chemistry.

To identify whether the yacon supplementation potentiate the effects of the HFD reversion to a standard diet, we performed a second experimental design. Blood samples were collected into plane glass tubes.

Yacon [ Smallanthus sonchifolia Poepp. As previously reported by us, yacon roots exhibit a lipid lowering effect, mainly reducing serum triglycerides and VLDLc levels, invrstigaciones normal and diabetic rats [ 1725 ].
