Verdict: 🟢 Safe
Per 100g: 10 mg
Data: Harvard T.H. Chan SPH (2024)

Putting Chickpea Flour in context: it lands well below the category average of 20 mg. In the database, 73% of legumes (44 of 60) fall in the 🟢 Safe group (under 25 mg oxalate/serving). The typical legumes here averages 20 mg oxalate per serving, so Chickpea Flour runs 90% 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 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. Applied to Chickpea Flour: 2 mg oxalate per 1/4 cup — Safe per Harvard (2024).
Can I eat this food every day?
Daily eating is fine for Safe foods (under 25 mg/serving). For Caution or Avoid foods, spread them out and alternate with low-oxalate picks. The idea is keeping your weekly oxalate load manageable, not eliminating any single food. For Chickpea Flour, the measured oxalate value is 2 mg per 1/4 cup (Safe).
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. For Chickpea Flour, the measured oxalate value is 2 mg per 1/4 cup (Safe).
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 Chickpea Flour: 2 mg oxalate per 1/4 cup — Safe per Harvard (2024).
