😂 I have to admit that I rarely eat or even taste feet, so I'm not a reliable source. Let me phrase it this way, if my or my wife's feet would taste even remotely like this smoothie, I'd permanently have a big toe in my mouth.
So, no, it tastes really nice. I was skeptical, too, initially, particularly because of the otherwise earthy taste of beetroot juice, but you won't taste that at all. The banana imparts probably the strongest flavor, and if you throw in a kaki (persimmon) you'll have a really pleasant surprise.
