Journal of Clinical Investigation. Oligofructose promotes satiety in rats fed a high-fat diet: Effects of yacon flour on the adipose tissue of HFD-fed rats and adipogenesis-related genes. This may also be due to the use of Aloe vera, because of its chemical composition and the amount of phenolic compounds that inactivate the polyphenol oxidase that is responsible for enzymatic browning in many fruits. LDL-cholesterol concentration was determined by a two-step homogeneous assay without precipitation.

Yacon syrup: beneficial effects on obesity and insulin resistance in humans.

Weight loss during oligofructose supplementation is associated with decreased ghrelin and increased peptide YY in overweight and obese adults. Journal of Nutritional Biochemistry.

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 ].

Therefore, the effect of yacon on modulating these adipokine levels in HFD rats was evaluated. As can be seen from the Table, the volume fraction data varies with regard to pressure and time. Given that r is defined as the relation between investgaciones pressure and working pressure, the x axis provides information about the index of pressure-gradient intensity [ 29 ].

Yacon: health benefits and technological applications

Studies in the Heliantheae Asteraceae. It is worth adding that the impregnated sample was not unpleasant for the evaluator, as expressed in the comments on the sensory evaluation chart used. Previous studies demonstrated that fientificas yacon supplementation reduces e, serum triglycerides in normal rats, without toxicity or adverse nutritional effects [ 17 ].


It is interesting to note that the beneficial effects in lipids metabolism are more evident when yacon supplementation is accompanied by a standard diet. Additionally, adiponectin and leptin have been implicated in adipose tissue dysfunction [ 6 ].

Additionally, decrease in fasting serum insulin and Cientififas Model Assessment index was observed. Leptin, another adipokine, regulates weight balance, glucose, and lipids metabolism [ 52 ].

In Table 1 we present the results obtained by applying different pressures and times for impregnation, with a relaxation time of 10 min for all the samples. The pathogenesis of obesity-associated adipose tissue inflammation; pp. The high-density lipoprotein cholesterol HDLc was determined after precipitation of very low-density lipoprotein VLDL and low-density lipoprotein LDLc innvestigaciones polyanions dextran sulphate and magnesium chloride.

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

Yacon syrup: beneficial effects on obesity and insulin resistance in humans.

The authors stressed the importance of internal variables, such as the number and diameter of pores, the mechanical properties of the solid matrix as well as the spatial distribution and characteristics of the cells, and also the type of fluid liquid or gas present in the intercellular space, which have to be taken into consideration in order to make precise adjustments to vacuum impregnation treatments. Journal of Agricultural and Food Chemistry.

Dietary polyphenols as potential nutraceuticals in management of diabetes: Experiment 2 In a second design, after 12 weeks rats which fed standard diet continued with the same chow, while animals under HFD were changed to a standard diet with or without yacon, according to the following scheme Figure 1. The average growth rate for rats on the HFD was As can eobre seen, the sensory evaluation of taste was significant. Discussion Nutritional strategies represent alternatives to pharmaceutical approaches for reducing hyperglycemia and body weight [ 13 ].


In contrast, the serum triglycerides curve of HFD Y rats did not increase considerably from the baseline, being similar to that from SD rats. Gcg a and polypeptide YY: While adiponectin levels reduce in response to excessive fat depots, plasma leptin concentrations are positively associated with the amount of body fat [ 53 ].

The vacuum period and relaxation times represent two important variables that affect the results of applying VI. Guillemin, P Degraeve, C. It can be noted a trend for bakery products formulations using yacon flour, and the outcomes were positive for both technological properties as well as for sensory xientificas.

By optimizing maximizing the process, the highest volume fraction and mass fraction that is obtained is Establishing the effective volume fraction In Table 1 we present the results obtained by applying different pressures and times for impregnation, with a relaxation time of 10 min for all the samples.

In order to assess whether the yacon modifies lipid absorption at the intestinal level, we perform an oral triglyceride loading test. Articles from Journal incestigaciones Obesity are provided here courtesy of Hindawi Limited.
