4. Yacon
Yacon is a tuber that is native to Peru, and it’s another traditional remedy for constipation. A study performed in 2008 and published in the journal Digestion tested the effects of yacon syrup on the digestion of healthy volunteers. Based on their results, the study authors wrote:
“Yacon markedly accelerates colonic transit in healthy individuals. Further studies are needed in constipated patients to confirm this preliminary data. Due to the low caloric content of yacon, the root could be a useful treatment in constipated diabetics or obese patients.”
