per serving
Serving: 1/4 cup (37 g)
Verdict: 🟢 Safe
Per 100g: 19 mg
Data: Harvard T.H. Chan SPH (2024)
Here's the takeaway: Baking Flour earns a Safe rating (🟢) at 7 mg oxalate per serving. Being under 25 mg means it fits comfortably in everyday eating. Keep your usual habits — adequate fluids and calcium in meals — and Baking Flour poses no special concern.
Putting Baking Flour in context: it lands below the category average of 14 mg. In the database, 84% of grains & pasta (170 of 201) fall in the 🟢 Safe group (under 25 mg oxalate/serving). The typical grains & pasta here averages 14 mg oxalate per serving, so Baking Flour runs 50% below that baseline. That places it among the lower-oxalate options in its category. Why this matters: the gap between two Safe foods can be wide — one may hold 5 mg oxalate while another sits at 24 mg. The lower one leaves more room in your day.

Why does the safe threshold matter?
The 25 mg per serving threshold is based on clinical guidance for kidney stone patients. Harvard's lab data (2024) provides the most reliable oxalate measurements available — no database estimates, direct lab analysis. Baking Flour comes in at 7 mg oxalate per 1/4 cup (Safe) in the measured database.
Can I eat this food every day?
If it's in the Safe zone (under 25 mg/serving), yes — it can be a regular part of your diet. For Caution or Avoid foods, frequency matters. Rotate them with lower-oxalate options throughout the week. Baking Flour comes in at 7 mg oxalate per 1/4 cup (Safe) in the measured database.
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. Applied to Baking Flour: 7 mg oxalate per 1/4 cup — Safe per Harvard (2024).
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 Baking Flour, the measured oxalate value is 7 mg per 1/4 cup (Safe).
