Why does the safe threshold matter?

Where does the oxalate data come from?
The numbers come from Harvard T.H. Chan SPH's 2024 laboratory measurements, published through the OHF database. Direct lab analysis, which is why they're treated as the reference values for food oxalate. Soy milk (Vanilla) comes in at 2 mg oxalate per 1 cup (Safe) in the measured database.
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, Soy milk (Vanilla) measures 2 mg per 1 cup, rated Safe.
