Abstract: Yacon is a traditional herb originated from South America, well positioned as nutraceutical food product because of increase presence of dietary fiber (fructooligosaccharide) content in it. The objective of this research is to explore ameliorative benefit against elevated blood sugar level in elders. Obese, hypoglycemic elders were selected and divided evenly into two groups (G0 and G1), having 10 subjects. G1 were given 20g of yacon powder twice a day. Hba1c test was performed before initiation and after termination of trail. Result obtained (at p-value <0.05) showed that the given dose of yacon powder was statistically significant in reducing the serum glucose levels in elderly.
