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. Syrup (Barley Malt) comes in at 4 mg oxalate per 1 tbsp (Safe) in the measured database.
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, Syrup (Barley Malt) measures 4 mg per 1 tbsp, rated Safe.
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 Syrup (Barley Malt), the measured oxalate value is 4 mg per 1 tbsp (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. Applied to Syrup (Barley Malt): 4 mg oxalate per 1 tbsp — Safe per Harvard (2024).
