Verdict: 🟡 Caution
Per 100g: 78 mg
Data: Harvard T.H. Chan SPH (2024)
The bottom line for Chex Cereal: Caution (🟡) at 46 mg oxalate per serving. It's the middle of the road — usable, but with guardrails. Half portions, occasional frequency, calcium pairing, and watching your total daily intake keeps it workable.
Putting Chex Cereal in context: it lands well above 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 Chex Cereal runs 231% above that baseline. That places it on the higher end for oxalate 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 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. Chex Cereal comes in at 46 mg oxalate per 1 serving (Caution) in the measured database.
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. Applied to Chex Cereal: 46 mg oxalate per 1 serving — Caution per Harvard (2024).
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. Chex Cereal comes in at 46 mg oxalate per 1 serving (Caution) in the measured database.
Should I also check sodium and calcium?
Yes — kidney stone risk isn't just about oxalate. High sodium increases urinary calcium (a stone promoter). Adequate dietary calcium (from food, not supplements) actually binds oxalate in your gut.
