Yacon also has anti-oxidant phenolic acids, chlorogenic acid, ferulic acid caffeic acid, all active free radical scavengers. Along with that, it has been reported that yacon has free tryptophan, an essential amino acid for protein synthesis.
Yacon has some very unique properties, and these are now finding their way to the marketplace in forms we can use to benefit our own health. In tests on obese pre-menopausal women over a period of 120 days, they were given yacon syrup twice per day. At the end of the 120 day period, there was a significant decrease in body weight, waist circumference and body mass index. The researchers concluded that yacon syrup is a good source of fructooligosaccharides, and the long term (120 day) consumption was beneficial. In another study, freeze-dried powdered yacon was found to be a good source of FOS, and that daily consumption can have a beneficial effect on serum glucose in the elderly. Powder, being easy to use and store, makes this even more viable as an addition to one’s health regimen.
