Tuna and White Bean Salad with Parsley: where the numbers come from
Each ingredient is matched to a record in the Australian food-composition data, that record's per-100 g values are scaled to the weight the recipe uses, the results are added, and the total is divided by 2 servings. This page shows all of it, so the estimate can be checked rather than taken on trust.

Oxalate
233 mg per serving (466 mg for the whole recipe, divided by 2). This comes from the Oxalosis and Hyperoxaluria Foundation list rather than the Australian composition data above, which does not carry oxalate.

Oxalate in a plant moves with variety, ripeness, soil and cooking, and what you absorb depends on the calcium eaten in the same meal rather than on the figure alone. The full table and what it is worth.
Not counted
These lines contribute nothing to the figures above, because they carry no weight or no composition match. Finishing salt and pepper added to taste are deliberately excluded: the amount is the cook's, so counting it would be inventing a number.
- Ground black pepper, to taste
Why these records
Where a generic database item cannot represent an ingredient exactly, the choice is recorded with the ingredient rather than left to inference.
- Tuna
- Recipe lines say canned in water and drained; ledger key carried over verbatim from the published book.
- No-Added-Salt Cannellini Beans
- Used where a recipe specifies canned no-added-salt cannellini or white beans, drained and rinsed. Mapped to the dried-boiled record rather than the canned one, which carries 270 mg of sodium per 100 g from brine the recipe pours away. The same rule the frozen peas and the corn already follow. A real no-added-salt can retains a little sodium from its packing water, so this understates slightly rather than overstating by ten times.
- Cherry Tomatoes
- Weighed raw whole or halved before roasting; ledger key carried over verbatim from the published book.
- Cucumber
- Weighed raw, mostly unpeeled and diced or cut into matchsticks; ledger key carried over verbatim from the published book.
- Carrot
- Weighed raw, peeled and sliced or grated, before any cooking; ledger key carried over verbatim from the published book.
- Flat Leaf Parsley
- Weighed raw as fresh leaves for finishing; ledger key carried over verbatim from the published book.
- Lemon Juice
- Measured as squeezed juice, not whole fruit; ledger key carried over verbatim from the published book.
- Olive Oil
- Measured from the bottle, plain or extra-virgin; AUSNUT has a single olive oil record and the ledger key is carried over verbatim.
- Wholegrain Bread
- Weighed as bought to serve alongside; ledger key carried over verbatim from the published book.
What this is and is not
These figures match the ones shown on the recipe page exactly, because both come from this same arithmetic.
A composition database gives representative values for a food, not an analysis of your tin, your loaf or your cut of meat. Brands differ, produce varies, and yields change with how long something cooked and how hard it was drained. Treat every figure here as an estimate of the right order rather than a measurement, and where a number matters clinically, take it to whoever is managing your care. CERNERE publishes the working so it can be argued with, not to imply a precision food does not have.
