An unremarkable-seeming fruit with a genuinely substantial fibre contribution in a single serving.

Pears sit in similar territory to apples — a genuinely ordinary, shelf-stable fruit whose research profile is easy to overlook precisely because it's so unremarkable-seeming at the grocery store.
A medium pear with skin provides a substantial share of a day's fibre target in a single piece of fruit, split between soluble and insoluble types (see our fibre types deep dive). Pear skin also contains quercetin, though generally in smaller amounts than apple skin — still a meaningful contribution alongside the fruit's fibre content.
Pears are unusual among common fruits in that they're typically picked and sold underripe, ripening off the tree — a pear left at room temperature for a few days after purchase will develop noticeably more flavour and softness than one eaten straight from a cold grocery display, without any change in its basic nutritional profile.
Eaten whole with the skin on (where the fibre and quercetin concentrate), sliced into a salad, or paired with a hard cheese for a simple, low-effort snack.
Like apples, canned pears in syrup and pear juice lose most of the fibre that makes whole pears useful — whole fruit remains the better choice here too.
