Yacon Concentrate: Nature at Its Best

The sugar in yacon is mainly fructooligosaccharides (FOS) that pass through the digestive system without being metabolised, as the human system doesn’t have an enzyme to hydrolyze FOS. Therefore, it is good for people with diabetes and all people concerned about blood sugar levels. It is probably the only natural supplement of FOS without chemical purification. Therefore, yacon syrup also retains the advantage of other plant constituents such as polyphenol antioxidants.

Why New Zealand grown yacon?

Three cultivars of Yacon were brought into New Zealand by Plant & Food Research in early 1990’s. Dr. Robert Welch, Dr. Jim Douglas, and their team experimented with different cultivars in ten growing areas across north and south of New Zealand for the highest production of natural FOS. New Zealand is now growing some of the most FOS-abundant yacon in the world.

Why take prebiotic FOS?

The human gut microbiome is one of the most promising areas of study in medicine and human biology. Research has that most of the modern plagues can be traced back to an imbalance gut microbiome. Studies have shown that prebiotic FOS can selectively nourish the good bugs, and create an environment that inhibits the bad ones, helping to reset the balance of your gut microbiome.

Why natural FOS?

In 2013, researchers from Japan compared the difference of the prebiotic effect between yacon and commercialised FOS. The study shows that natural FOS is capable of stimulating gut microbes to produce twice as much beneficial SCFA (Short Chain Fatty Acids) as commercialised FOS can.
