❓ Frequently Asked Questions
Should I avoid Flour if I have kidney stones?
It's fine. Flour has 1 mg of oxalate per 1/4 cup. That's low enough that kidney stone patients don't really need to worry about it. Harvard did the measuring, not us.
What's the oxalate content of Flour?
Quick math: 1/4 cup of Flour = 1 mg oxalate. 100g = 3 mg. Both numbers come from Harvard's latest lab measurements. Not AI, not a database, actual lab work.
Is Flour low or high oxalate?
Low. 1 mg per 1/4 cup puts Flour firmly in the low-oxalate category. Safe for regular eating if you're managing kidney stones.
What can I eat instead of Flour?
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 Flour with a fraction of the oxalate.
How much sodium does Flour have?
The sodium level is fine — 47 mg/100g. If all your foods looked like this on sodium, you'd be in great shape for stone prevention.
