🎃 Squash & Gourd — 🟢 Oxalate Safe Foods

Squash and gourds are among the most predictable subgroups: summer squash, zucchini, and cucumbers all sit in the lowest brackets at realistic servings, which makes them the volume vegetables of a stone-aware plate. The winter squashes — butternut, acorn, pumpkin — run moderately higher, concentrated further by the dense cooked flesh a typical serving contains. Pumpkin deserves one specific note: fresh pumpkin is moderate, but canned pumpkin packs several servings of flesh into each cup, and snack pumpkin seeds belong to an entirely different, much higher category. Cucumber is the subgroup's quiet standout: essentially free of oxalate, endlessly usable as a raw snack, and a hydration contributor besides.

Vegetables are the widest-oxalate-spread food group in the database: a cucumber measures around 1 mg of oxalate per serving while a half-cup of cooked spinach approaches 493 mg. That spread is why blanket advice like 'eat more vegetables' does not work for stone patients. What matters is the specific leaf, the serving, and the preparation. Boiling and draining can remove a meaningful share of soluble oxalate from many greens, and pairing any higher-oxalate vegetable with a calcium-rich food at the same meal reduces absorption. Low-oxalate anchors in this group include cucumber, lettuce, and most squash varieties; the leafy dark greens are the ones to portion carefully.

This page isolates one slice of a food category: a single verdict within a single subgroup. That granularity matters because categories are rarely uniform — leafy greens, for example, contain both near-zero-oxalate lettuces and very-high-oxalate spinach. Knowing which foods earned the safe, caution, or avoid label within a subgroup lets a stone patient shop with precision instead of avoiding whole food families.

["Everything on this page cleared the measurement bar: each food's oxalate per standard serving sits low enough that portion anxiety is unnecessary. That is a working distinction, not a technicality — a diet assembled from this list behaves like normal eating, with no arithmetic at the table. The habits that matter elsewhere (measuring, pairing with calcium, choosing preparation forms) can all be switched off for foods here, which is precisely what makes the overall pattern sustainable month after month.", 'Two footnotes keep this tier honest. First, safe refers to oxalate only — the sodium, sugar, and overall quality columns still apply, especially on packaged items. Second, safe is per standard serving: an unusual portion of even a low food adds up, though the slope is gentle enough that it rarely needs watching. For most stone patients this page is the shopping list; the caution and avoid pages are the reference material.']

This view isolates the Oxalate Safe slice of Squash & Gourd: 19 foods share both the subgroup and the rating, so the oxalate values here are directly comparable for meal planning — no need to mentally adjust for different food families.
