Why does the safe threshold matter?
The 25 mg cutoff comes from clinical guidance for stone formers. Below it, a food's oxalate contribution is small enough not to move the needle for most patients. Harvard's 2024 lab data sits behind these figures — direct measurements, not estimates. For context, Sauce (Pasta/Marinara) measures 3 mg per 2 tbsp, rated Safe.
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. Sauce (Pasta/Marinara) comes in at 3 mg oxalate per 2 tbsp (Safe) in the measured database.
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. For context, Sauce (Pasta/Marinara) measures 3 mg per 2 tbsp, rated Safe.
Should I also check sodium and calcium?
Definitely. Oxalate is only part of the story — high sodium raises calcium in urine, and dietary calcium (from food, not pills) binds oxalate in the gut. The food's main page lists both, so it's worth checking before you plan around it. For context, Sauce (Pasta/Marinara) measures 3 mg per 2 tbsp, rated Safe.
