Resumen:
Objectives:
Syrup obtained from yacon roots could be well positioned as a nutraceutical
product due to its high fructooligosaccharides content. We examined the
beneficial effects and tolerance of yacon syrup on human health.
Methods:
Obese and slightly dyslipidemic pre-menopausal women were studied over a
120-day period in a double-blind placebo-controlled experiment. We administred
twice a day a dose of 145mg or 70mg fructooligosaccharides/kg/day of yacon
syrup containing 41.39% FOS. At the start and end of the study, anthropometric
measurements, blood glucose, calcium, lipid and insulin concentrations and
Homeostasis Model Assessment index were determined.
Results: The
recommended daily consumption of yacon syrup with no undesirable
gastrointestinal effects is 140mg fructooligosaccharides/kg. Daily intake of
yacon syrup produced a significant decrease in body weight, waist circumference
and body mass index. Additionally, decrease in fasting serum insulin and
Homeostasis Model Assessment index was observed. The consumption of yacon syrup
increased defecation frequency and satiety sensation. Fasting glucose were not
affected by syrup but a positive effect was found in serum lipids in
triglicerides and LDL-cholesterol levels.
Conclusions:
Yacon syrup is a good source of fructooligosaccharides and its long-term
consumption produced beneficial health effects on obese pre-menopausal women
with insulin resistance.
