The stone plan's anchors are the store's value items: rice, beans, lentils, eggs, canned tuna and salmon, frozen vegetables, and milk. All measure at the safe end of the oxalate table, all store well, and all cost less per serving than the packaged convenience foods they replace. The expensive parts of a typical grocery cart — the ready meals, the snacks, the drinks — are exactly the parts the stone plan portions anyway. The budget kitchen is not a compromise version of the stone diet; it is the stone diet's natural form.
The table below shows the measured values of the low-cost staples that anchor the budget stone kitchen.
| Food | Oxalate (mg) | Serving | Rating |
|---|---|---|---|
| Rice, cooked | 2 | 1/2 cup | Safe |
| Dried beans, cooked | 5 | 1/2 cup | Safe |
| Lentils, cooked | 3 | 1/2 cup | Safe |
| Eggs, hard-boiled | 0 | 2 large | Safe |
| Canned tuna | 0 | 3 oz | Safe |
| Canned salmon | 0 | 3 oz | Safe |
| Milk, cow's | 0 | 1 cup | Safe |
| Frozen broccoli | 4 | 1/2 cup | Safe |
| Frozen green beans | 4 | 1/2 cup | Safe |
| Frozen spinach | 75 | 1/2 cup | Avoid |
The budget kitchen runs on the batch method: a pot of beans and a pot of rice cooked once and portioned across the week costs a fraction of the packaged equivalent and carries the stone-safe staples. The measured version of the budget week is the same structure as every kitchen on this site — protein, vegetables, a grain, and dairy — built from the value items. The frozen vegetables measure the same oxalate as fresh, at a lower price and with no spoilage, and the milk is the budget kitchen's calcium anchor. The family that cooks the batch week has the stone plan and the budget plan running on the same pot.
The measured SNAP cart follows the stone plan's priorities: the value staples first (rice, beans, eggs, milk, frozen vegetables, canned fish), the produce that survives the week (bananas, apples, oranges, carrots), and the packaged snacks treated as the occasional items they are. The two categories the budget cart can skip without losing anything are the sweet drinks and the ready meals — both are the stone plan's portioned items anyway, and both are the cart's most expensive per-serving items. The cart that buys the staples and the produce has the stone-safe week at the lowest cost.
The budget kitchen extends beyond the cart: farmers markets with SNAP matching programs, food pantries, and the school meal programs all carry stone-safe options, and the measured version uses them deliberately. The food-pantry staples — rice, beans, canned vegetables — are the stone-safe staples, and the school breakfast and lunch programs deliver the dairy and produce the budget week otherwise stretches to cover. The family managing stones on a budget does not need a special pantry; it needs the measured version of the resources already available.
No — its staples are the store's value items: rice, beans, eggs, canned fish, frozen vegetables, and milk all cost less per serving than the packaged foods they replace. The expensive parts of the cart are the parts the stone plan portions anyway.
Eggs, dried beans, lentils, canned tuna, and canned salmon — all measure zero or low oxalate, all cost pennies per serving, and all store well. The batch method (a pot cooked once, portioned across the week) stretches them further.
For the stone plan, yes — the frozen versions measure the same oxalate as fresh, at a lower price and with no spoilage. The exception is the frozen high-oxalate greens like spinach (75 mg per half-cup), which get the same portioned treatment as fresh.
The budget stone menu is buildable on a fixed loop: beans and rice for the week's lunches, eggs for breakfast, canned tuna for two dinners, a chicken batch for the rest, frozen vegetables at every dinner, and milk as the family drink. The loop's cost per serving is a fraction of the packaged alternative, and its oxalate column is the safe one — the same measured plate the stone plan uses everywhere, at the store's lowest prices. The weekly menu is the budget kitchen's version of the batch session: one planning hour, one grocery run, and the measured week assembled from the same staples.
The loop also protects against the budget kitchen's real risk, which is not price but drift: the weeks when the staples run low and the convenience foods take over. The measured version keeps the staple shelf stocked — the rice, beans, eggs, and milk that anchor the loop — so the drift never gets a foothold. The budget kitchen that protects the staple shelf has the stone plan protected with it.
