Conclusions : In summary , the use of ITF may have benefits for LDL-c reduction across all study population s , whereas HDL-c improvement and glucose control were demonstrated only in the T2DM subgroup .
Overall , ITF supplementation may provide a novel direction for improving the lipid profile and glucose metabolism
Freeze-dried powdered yacon: effects of FOS on serum glucose, lipids and intestinal transit in the elderly
Abstract Background and aims Freeze-dried powdered yacon ( FDY ) can be considered a prebiotic product due to its fructooligosaccharides ( FOS ) content . The effect of 9 weeks of daily intake of FDY containing 7.4 g of FOS on glucose , lipid metabolism and intestinal transit in a group of elderly people was investigated . Methods Seventy-two elderly ( mean age 67.11 ± 6.11 ) men and women were studied for 9 weeks in a double-blind , placebo-controlled experiment . They were r and omly assigned to the supplement group ( which received 7.4 g of FOS as FDY ) or the control group . At the beginning and end of the study , anthropometric measurements , blood sampling , clinical analyses and dietary intake were assessed . Results A daily intake of FDY containing 7.4 g of FOS for 9 weeks was associated with a mean decrease in serum glucose ( p = 0.013 ) , but supplementation did not reduce serum lipids in the study group . The administered dose did not adversely affect intestinal transit . It did not cause bloating , flatulence or intestinal discomfort . Conclusion Freeze-dried powdered yacon is a good source of FOS , and daily consumption can have a favourable effect on serum glucose in the elderly . It is also practical , easy and safe to use and store
Conclusions : In summary , the use of ITF may have benefits for LDL-c reduction across all study population s , whereas HDL-c improvement and glucose control were demonstrated only in the T2DM subgroup .
Overall , ITF supplementation may provide a novel direction for improving the lipid profile and glucose metabolism
