Yacon Reduces Inflammation in Visceral Adipose Tissue of HFD-Fed Rats It is known that excessive adipose tissue expansion leads to adipose macrophage infiltration and metabolic dysfunction contributing to low-grade local and systemic inflammation [ 2 ].

Within this context, vacuum impregnation VI has been largely used to obtain a rapid penetration of solvated compounds in plant tissues together with a homogeneous concentration profile of the solutes in the final products [ 12 ].

The vacuolar accumulation of CO from organic acids, specifically malic acid, makes it possible to quantify its content and in this way to calculate the total presence of Aloe. Please review our privacy policy. Oblitas Cruz y E. In this way, we analyzed whether yacon could modulate inflammatory markers in visceral fat and serum. Figure 2 shows the effects of each independent variable on volume fraction X and Figure 3 shows the effects on mass fraction X mhd.

Fasting glucose and serum lipids were not affected by investigaxiones treatment and the only positive effect was found in serum LDL-cholesterol levels.

Yacon: health benefits and technological applications

How to cite this article. Critical Reviews in Biochemistry and Molecular Biology, v. The recommended daily consumption of yacon syrup with no undesirable gastrointestinal effects is 0. Journal of Agricultural and, Food Chemistry v.

Table 3 shows the effects of yacon flour consumption on relative organ weights. In addition, dietary polyphenols directly or indirectly impact on gut function, decreasing pathogenic bacterial growth and promoting the production of the microbial short chain fatty acids by beneficial microbial populations [ 23 ].


Changes in protein expression of Akt, the most important molecule of the insulin cientoficas in target organs, were measured using Western blot analysis Figure 5 f.

The growing scientific interest in yacon is due to its abundant source of fructan, fructo-oligosaccharides FOSinstead of starch [ 2 ]. Additionally, yacon roots present strong antioxidant activity and anti-inflammatory effects preventing the risks associated with metabolic diseases [ 27 — 29 ].

The sensory evaluation of the 10 semi-trained panel members showed that the p-value for color was 0. Table 1 Chemical characterization of yacon flour. Discussion Nutritional strategies represent alternatives to pharmaceutical approaches for reducing hyperglycemia and body weight [ 13 ]. While adiponectin levels reduce in response to excessive fat depots, plasma leptin concentrations are positively associated with the amount of body fat [ 53 ]. Journal of Ethnopharmacol, v.

Therefore, the effect of yacon on modulating these adipokine levels in HFD rats was evaluated. No significant changes were observed for the spleen and pancreas in all the studied groups. We wish to thank to Dr. Additionally, decrease in fasting serum insulin and Homeostasis Model Assessment index was observed.

The SD group was fed ad libitumwith a standard chow diet containing Metabolic remodeling of white adipose tissue in obesity.

When a short vacuum period is applied, the elimination of gases from the pores is not completed, and thus the gas residues could cienfificas impeded penetration by the solution.

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

The only organic acid contained in the gel of fresh Aloe leaf is malic acid. Materials and methods 2. Abstract Smallanthus sonchifolius yacona native plant of South America, was observed to improve lipid profile in rodents and humans.


Dietary fiber and body weight.

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

In general, the higher the porosity, the higher the level of impregnation [ 29 ], [ 33 ] showed that the levels of impregnation were directly correlated with the porosity values of the vegetables.

This simple dietary intervention appears to be capable of improving obesity outcomes regardless of susceptibility to an obesogenic nutritional environment.

Updates on obesity pharmacotherapy. In accordance with this finding, fasting glucose, glucose tolerance, and insulin resistance were also improved being the blood glucose concentrations similar to those of the SD rats during the glucose challenges Figures 7 f and 7 g.

Table 4 presents the results of the chemicophysical analysis of the yacon impregnated with Aloe vera after dehydration. Effects of fructans-type prebiotics on lipid metabolism. Dietary supplements have been proposed to promote weight loss or appetite suppression in the management of obesity. Animals were weighed g weekly throughout the experimental period. Guillemin, P Degraeve, C. Response Surface Methodology RSM allowed the optimization of mass fraction and volume fraction at a pressure of These results corroborate the premise that vacuum gauge pressure is the driving force in the process of vacuum impregnation, given that it was the most relevant effect.
