In a second design, after 12 weeks rats which fed standard diet continued with the same chow, while animals under HFD were changed to sobr standard diet with or without yacon, according to the following scheme Figure 1.

Yacon: health benefits and technological applications

Potencialidades do yacon Smallanthus sonchifolius no diabetes Mellitus. Morphometric and Nutritional Determinations Animals were weighed g weekly throughout the experimental period.

Yacon roots have special features which include high water content and large amount of soluble dietary fibers, with low energy density [ 14 ]. We examined the beneficial effects and tolerance of yacon syrup on human health.

Yacon effects in immune response and nutritional status of iron and zinc in preschool children. Changes in protein expression of Akt, the most important molecule of the insulin signaling in target organs, were measured using Western blot analysis Figure 5 f. Robinson] invrstigaciones composition and use: Additionally, decrease in fasting investigacioness insulin and Homeostasis Model Assessment index was observed.

After 12 weeks on HFD or standard chow, the animals were randomly divided into the following groups according to the treatment with or without the addition of yacon flour as a dietary supplement for 8 weeks Figure 1.

Fasting glucose and serum lipids were not affected by syrup treatment and the only positive effect was found in serum LDL-cholesterol levels. Adiponectin is the most abundantly adipokine expressed in adipose tissue with pleiotropic insulin-sensitizing effects. Conclusion The data presented in this study suggest that yacon may act by different ways to suppress body weight gain, food intake, FER levels, weight and size of adipose invvestigaciones, and serum levels of triglyceride and improve adipokine profile in HFD-fed rats.

The SD yacno was fed ad libitum sobree, with a standard chow diet containing Services on Demand Article.

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

In order to assess whether the yacon modifies lipid absorption at the intestinal level, we perform an oral triglyceride loading test. PPAR gamma agonism increases rat adipose tissue lipolysis, expression of glyceride lipases, and the response of lipolysis to hormonal control. FASleads to changes in the activity of key proteins involved in lipids and fatty acids metabolism, inflammation, and cell-cycle regulation [ 5 ].

These data led us to believe that visceral fat may be a target of yacon effects. This allows us to suggest that inhibition of MCP-1 by yacon supplement could lead to a low level of macrophage infiltration contributing to reduce adipose tissue inflammation improving insulin resistance and metabolic state.

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 ]. What stands out is the high carbohydrate content of yacon.

Prebiotic effectiveness of fructans of different degrees of polymerization. Additionally, the presence chlorogenic and caffeic acid in yacon roots could also contribute to the hypolipidemic effect observed after yacon supplement [ 18 ]. Proximate analysis gave results of: This effect was more pronounced when yacon was accompanied by a standard diet. 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 ].

Caffeic acid derivatives in the roots of yacon Smallanthus sonchifolius.

Iron bioavailability from ferric pyrophosphate in rats fed with fructan containing yacon Smallanthus sonchifolius flour. Yacon consumption is related to the promotion of human health benefits, such as hypoglycemic effects [ 3 ], [ 4 ]antioxidant activity [ 5 ] ; potential chemoprevention against colon carcinogenesis [ 6 ].

Nutritional parameters were calculated based on food and caloric intake: By optimizing maximizing the process, the highest volume fraction and mass fraction that is obtained is After clotting, samples were centrifuged and serum was used for biochemical determinations. Dietary supplements have been proposed to promote weight loss or appetite suppression in the management of obesity.

Smallanthus sonchifolius yacona native plant of South America, was observed to improve lipid profile in rodents and humans. Diabetes Research and Clinical Practice. Such is the case mentioned in [ 30 ]where banana, mamey and mango displayed a linear increase in the values of X up to certain limits approximately mbarafter which the level of impregnation decreased.

Through linear regression of that data, the value of the slope corresponding to effective porosity is calculated, and where the straight line intercepts the x axis indicates the quantity of Aloe vera solution adhering to the fruit due to capillarity.
