Underneath this thesis are the assumptions that "taste" is (a) some objective thing that (b) is worth pursuing for its own sake, both of which I wholeheartedly reject.
The idea that "good taste" exists and matters is a form of social conservatism that communicates nothing of value and is inevitably self-serving. It is always possible to restate "X is more tasteful than Y" as "I and people I like/respect prefer X to Y" without losing information; the only thing that changes is the subtle implication that the speaker's subjective experience is in some way superior to that of others.
I encourage the author to go and eat a wild banana, to experience the raw, wondrous near-inedibility of nature untainted by humans' shameful lust for making things nicer.
