The plant-only kitchen splits into two measured groups. The free group — the vegetables and fruits that anchor a vegan plate at the safe end of the table — includes most greens beyond the spinach family, plus rice, oats, beans, lentils, apples, bananas, berries, and melons. The portioned group — spinach, Swiss chard, beets, almonds, cashews, peanuts, soy in concentrated forms, and chocolate — carries the oxalate load of the diet. The table below draws the map.
| Food | Oxalate (mg) | Serving | Rating |
|---|---|---|---|
| Rice, cooked | 2 | 1/2 cup | Safe |
| Oatmeal, cooked | 9 | 1/2 cup | Safe |
| Lentils, cooked | 3 | 1/2 cup | Safe |
| Black beans, cooked | 5 | 1/2 cup | Safe |
| Chickpeas, cooked | 4 | 1/2 cup | Safe |
| Tofu, firm | 10 | 1/2 cup | Safe |
| Broccoli, boiled | 4 | 1/2 cup | Safe |
| Spinach, cooked | 75 | 1/2 cup | Avoid |
| Almonds | 107 | 1/4 cup | Avoid |
| Peanut butter | 36 | 2 tbsp | Caution |
The vegan stone plan's hardest question is calcium: no dairy, and the plant calcium sources — leafy greens and fortified foods — overlap with the high-oxalate list. The measured answer is fortified plant milks, which deliver 300 mg of calcium per cup at near-zero oxalate, plus tofu set with calcium, plus the low-oxalate greens (broccoli, kale in cooked forms) that contribute without the spinach load. The fortified milk is the vegan dairy shelf: the calcium that binds the oxalate in the same meal, without the oxalate column of the greens it replaces.
Vegan protein swaps land on the oxalate table in a clear order: tofu and tempeh measure low, beans and lentils low, and the nut-and-seed proteins — almond butter, tahini, concentrated soy bars — carry the load. The measured vegan protein plate is beans, lentils, and tofu as the daily base, with the nut butters portioned and the nut-heavy protein bars treated as the measured treats they are. The plant-only diet does not need to avoid its staples; it needs the portioned group marked.
The measured vegan plate is buildable: a legume or tofu protein, a grain, the free vegetables, and the fortified-milk calcium layer at the same meal. The smoothie habit — the vegan breakfast of choice — needs the same eye: a spinach-and-almond-butter smoothie stacks the two highest-oxalate groups in one glass, and the measured version uses kale or frozen zucchini, a banana, and fortified soy milk instead. The smoothie is where the vegan plan most often quietly concentrates oxalate, and it is the easiest place to fix it.
Yes — a measured plant-only diet is workable. The free group (rice, oats, beans, lentils, tofu, broccoli, most fruits) anchors the plate, the portioned group (spinach, beets, nuts, peanut butter, chocolate) is marked, and fortified plant milk provides the calcium at near-zero oxalate.
Fortified plant milks (about 300 mg per cup, near-zero oxalate), calcium-set tofu, and the low-oxalate greens like cooked kale and broccoli. The fortified milk is the vegan dairy shelf — the calcium that binds oxalate at the same meal.
It stacks two high-oxalate groups in one glass: spinach at 75 mg per half-cup cooked and almond butter at about 107 mg per quarter-cup. The measured smoothie uses kale or zucchini, a banana, and fortified soy milk — the same nutrition with the oxalate column cut.
The fortified plant milk is the vegan plan's key measured tool, and its math is worth stating plainly: about 300 mg of calcium per cup at near-zero oxalate, which makes it the vegan equivalent of the dairy shelf. The measured vegan day includes the fortified milk at breakfast (in the oatmeal or the smoothie) and again at dinner (in the sauce or the glass), delivering the calcium that binds the oxalate of the meal. The plant milks differ by brand — the label's calcium line and the added-sugar line are the two numbers to check — and the unsweetened, fortified versions are the default. The vegan kitchen that treats the fortified milk as a staple, not a specialty item, has solved the calcium question the same way the dairy kitchen solves it.
The calcium-set tofu adds a second plant source: tofu processed with calcium salts delivers the mineral at a low oxalate load and doubles as the protein of the plate. The vegan plan's calcium is available; it just has to be chosen from the fortified and calcium-set items rather than assumed from the greens.
The measured vegan kitchen is a map, not a restriction: the free group anchors the plate, the portioned group is marked, and the fortified milk and calcium-set tofu carry the calcium the greens cannot. The plant-only diet does not need to leave the stone plan behind; it needs the map drawn, and the map is the same one every kitchen on this site uses — measured values, marked portions, and the calcium at the meal.
