Wow! A very “Japanesey” flavor of UME (tart and sweet apricot/plum) has been released. “High Fibre / Fat Blocking” Pepsi is how it is being advertised here in Japan. Zero Calories. The base flavor is classic Pepsi but the sour plum taste comes through nicely. A soda you can enjoy and with apparent health benefits. It can stabilize ones glucose level, lower serum lipids, and increase the absorbance of nutrients.
