โ“ Frequently Asked Questions

Can I eat Potato with kidney stones?

Yellow zone. 29 mg per 1/2 cup, chopped means Potato 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 Potato?

Quick math: 1/2 cup, chopped of Potato = 29 mg oxalate. 100g = 46 mg. Both numbers come from Harvard's latest lab measurements. Not AI, not a database, actual lab work.

Is Potato low or high oxalate?

Middle of the pack. 29 mg oxalate per 1/2 cup, chopped puts Potato in the moderate zone. Fine occasionally, not an everyday food.

What are the best low-oxalate alternatives to Potato?

Plenty of options. Scroll down to Related Foods โ€” every ๐ŸŸข green item there is a lower-oxalate alternative to Potato. Same food group, way less oxalate.

How much sodium does Potato have?

Sodium's not the issue here. Potato has 47 mg per 100g โ€” comfortably low. No need to worry about salt pushing extra calcium into your urine with this food.

How much Potato is safe to eat?

The portion math: 1/2 cup, chopped = 29 mg oxalate. Half serving = ~14.5 mg. With a 100 mg daily oxalate target, 29 mg from one food eats a big chunk of your budget. Go smaller.
