❓ Related Questions

Why does the safe threshold matter?

The 25 mg line is the reference point clinicians use to separate everyday foods from ones that need caution. Every value on this page traces back to Harvard's 2024 lab analysis, so the threshold is applied to measured data rather than estimates. For context, Snap peas measures 1 mg per 1 cup, rated Safe.

Can I eat this food every day?

Daily eating is fine for Safe foods (under 25 mg/serving). For Caution or Avoid foods, spread them out and alternate with low-oxalate picks. The idea is keeping your weekly oxalate load manageable, not eliminating any single food. Applied to Snap peas: 1 mg oxalate per 1 cup — Safe per Harvard (2024).

Where does the oxalate data come from?

Every oxalate figure is sourced from Harvard T.H. Chan SPH (2024), distributed via the OHF database. The values come from actual lab measurements of the foods — not from database averages or estimates. For context, Snap peas measures 1 mg per 1 cup, rated Safe.

Should I also check sodium and calcium?

Yes — kidney stone risk isn't just about oxalate. High sodium increases urinary calcium (a stone promoter). Adequate dietary calcium (from food, not supplements) actually binds oxalate in your gut. Check the food's full nutrition page for the complete picture. For Snap peas, the measured oxalate value is 1 mg per 1 cup (Safe).
