Thanks, Arthur. The banana adds a lot of flavor (it needs to be ripe). I mentioned this in response to another reader's comment. You can always add some other fruits to tilt the flavor towards your preference, but, as I said, banana is essential taste-wise. There is an "abbreviated" version of this smoothie that I periodically use as a substitute (just focusing on the arterial function effects): https://medium.com/right-to-rejuvenation/how-to-build-a-longevity-breakfast-439ee0fe48ae
