🔍 Key Insights

1 **Watch for high-risk items.** 15 foods (100%) are in the avoid category (100+ mg oxalate per serving). These stand out and deserve special attention. Check individual food pages for exact numbers.
2 **Big oxalate range.** The spread is 100 to 594 mg per serving — a 494 mg difference. Best pick: **Beet Powder** (100 mg). Most caution needed: **Swiss Chard** (594 mg).
3 **High average oxalate.** The mean is 305.0 mg per serving. These foods tend toward the higher end — proceed with caution and check individual values.
4 **Calcium benefit.** 4 foods (33%) provide 100+ mg calcium per 100g. Dietary calcium binds oxalate in your gut — getting enough calcium from food is actually protective against kidney stones.
