โ“ Frequently Asked Questions

Can I eat Flour with kidney stones?

Yellow zone. 74 mg per 1/4 cup means Flour sits in that middle ground where it's manageable but not risk-free. Half portions help. So does eating it less often.

What's the oxalate content of Flour?

Quick math: 1/4 cup of Flour = 74 mg oxalate. 100g = 283 mg. Both numbers come from Harvard's latest lab measurements. Not AI, not a database, actual lab work.

Is Flour a high-oxalate food?

Middle of the pack. 74 mg oxalate per 1/4 cup puts Flour in the moderate zone. Fine occasionally, not an everyday food.

What are the best low-oxalate alternatives to Flour?

Substitutes exist. The safe alternatives listed below are all low-oxalate foods in the same family as Flour. Grab one of those and you dodge the oxalate while keeping similar flavors.

How much Flour is safe to eat?

The portion math: 1/4 cup = 74 mg oxalate. Half serving = ~37 mg. With a 100 mg daily oxalate target, 74 mg from one food eats a big chunk of your budget. Go smaller.

0 mg sodium per 100g in Flour. Well under the 460 mg threshold. One less thing on your kidney stone checklist.
