How much oxalate is in Grain?
The lab result: 60 mg per 1/4 cup (30g serving). That's 200 mg per 100g. Harvard's ion chromatography analysis, 2024. Not crowdsourced, not estimated.
Is Grain low or high oxalate?
Middle of the pack. 60 mg oxalate per 1/4 cup puts Grain in the moderate zone. Fine occasionally, not an everyday food.
What are the best low-oxalate alternatives to Grain?
Don't give up the whole category — just pick a safer member of it. The green foods in the related section all work as substitutes for Grain with a fraction of the oxalate.
How much sodium does Grain have?
0 mg sodium per 100g in Grain. Well under the 460 mg threshold. One less thing on your kidney stone checklist.
