Most food aversions are learned, not innate, and can be systematically unlearned

Steingarten opens by confronting his own long list of foods he claimed to dislike, and rather than accepting these preferences as fixed facts about himself, he treats them as a hypothesis to be tested. He commits to eating disliked foods repeatedly, in varied preparations, tracking whether genuine exposure changes his reaction over time rather than simply confirming his existing bias.

The results surprise him: many aversions soften or disappear entirely once he actually gives a food repeated, fair trials rather than relying on a single bad childhood memory or an inherited family opinion about the food's unpleasantness. He treats this as evidence that taste preference is far more plastic and far less permanent than most people assume, shaped heavily by unexamined habit and social signaling rather than by fixed biology.

The experiment reframes fussy eating less as an immutable trait and more as an untested assumption most people never bother to challenge.

Takeaway: the foods you're sure you hate are often just foods you haven't given a fair, repeated chance.
