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. Applied to Brussel Sprouts (Raw): 14 mg oxalate per 1 cup — Safe per Harvard (2024).
Can I eat this food every day?
For Safe foods (under 25 mg/serving), daily use is generally fine. Caution and Avoid foods work better as occasional items — rotate them with safer options so no single high-oxalate food becomes a habit. For context, Brussel Sprouts (Raw) measures 14 mg per 1 cup, rated Safe.
Where does the oxalate data come from?
Harvard T.H. Chan School of Public Health (2024) via the OHF database. These are direct laboratory measurements — the most reliable oxalate data available for food. Brussel Sprouts (Raw) comes in at 14 mg oxalate per 1 cup (Safe) in the measured database.
Should I also check sodium and calcium?
Yes — oxalate alone doesn't decide stone risk. Sodium pushes more calcium into urine, and calcium from food (not supplements) helps bind oxalate during digestion. The main food page covers sodium and calcium alongside oxalate. Applied to Brussel Sprouts (Raw): 14 mg oxalate per 1 cup — Safe per Harvard (2024).
