❓ Related Questions

Which cooking method is best for reducing oxalate?

Boiling and discarding water = most effective (30-50% reduction). Steaming = moderate (5-15%). Roasting/baking = minimal. Raw = no reduction. For high-oxalate foods, boiling is always the preferred method.

How long should I boil?

Boil until just tender — typically 5-15 minutes for vegetables. The key step is discarding ALL cooking water. Never reuse it for soups, sauces, or cooking other foods.

Does cooking affect other nutrients?

Yes — boiling can reduce some water-soluble vitamins (B vitamins, vitamin C) while making others more available (lycopene in tomatoes, beta-carotene in carrots). It's a trade-off. For kidney stone patients, the oxalate reduction from boiling usually outweighs the vitamin loss.
