❓ Frequently Asked Questions
Should I avoid Corn if I have kidney stones?
Yep, you're good. Corn clocks in at 2 mg oxalate per 1/2 cup — way under the 25 mg cutoff. Eat it without the stress. Measured by Harvard, not guessed.
What's the oxalate content of Corn?
One 1/2 cup of Corn = 2 mg oxalate. Scale it up to 100g and you're at 3 mg. Direct measurement from Harvard, 2024. About as reliable as food data gets.
Is Corn low or high oxalate?
It's low. 2 mg per 1/2 cup is well under the 25 mg danger line. Corn is not the food you need to worry about.
What can I eat instead of Corn?
Substitutes exist. The safe alternatives listed below are all low-oxalate foods in the same family as Corn. Grab one of those and you dodge the oxalate while keeping similar flavors.
How reliable is the data for Corn?
The oxalate number for Corn — 2 mg per serving — is from Harvard's 2024 lab analysis. That part is solid. The USDA nutrition data (sodium, protein, calcium) is still being matched — we'll update when it's available.
