Researchers at the RIKEN Center for Sustainable Resource Science in Japan have developed a healthier form of starch in the cassava plant by reducing levels of starch branching enzymes (SBEs). This change increases the resistance of the starch to digestion and makes it a healthier food source. The team achieved this by suppressing multiple genes, resulting in a 63% increase in resistant tapioca starch. They believe this finding could lead to the development of functional foods that improve human health.
