Yacon syrup reduces postprandial glycemic response to breakfast: A randomized, crossover, double-blind clinical trial

摘要: Abstract Yacon is a root rich in fructooligosaccharides (FOS), which act as prebiotics. Numerous studies have shown promising results the technological aspects of producing yacon syrup. However, uncertainties exist concerning whether syrup can modulate postprandial glucose and lipid profiles. In order to assess effect on glucose, insulin triglyceride (TG) responses, randomized, crossover, double-blind clinical intervention with 40 women (20 normal weight 20 grade I obese) was performed. Participants underwent two-arms at least one-week wash-out period between visits. On each day, after 12 h fasting, an aliquot blood collected. For A, volunteers consumed breakfast +40 g placebo, whereas for B, participants (14 g FOS). Blood samples were drawn 15, 30, 45, 60, 90, 120 min. Glucose concentrations lowered intake compared placebo following times: 30 min 30 45 min insulin. conclusion, has decreasing adult women. This not evident concentration.
