❓ Frequently Asked Questions
Is Sorrel safe for kidney stones?
Bad news if you love Sorrel: 303 mg per 1/2 cup, chopped. That's many times what's considered safe. If kidney stones are your concern, this one's not your friend. Look for swaps.
What's the oxalate content of Sorrel?
The lab result: 303 mg per 1/2 cup, chopped (52g serving). That's 582 mg per 100g. Harvard's ion chromatography analysis, 2024. Not crowdsourced, not estimated.
Is Sorrel high in oxalates?
Yeah, it's high. 303 mg per 1/2 cup, chopped is way over the safe threshold. Sorrel belongs in the 'limit severely' column.
What are the best low-oxalate alternatives to Sorrel?
Substitutes exist. The safe alternatives listed below are all low-oxalate foods in the same family as Sorrel. Grab one of those and you dodge the oxalate while keeping similar flavors.
Does boiling Sorrel reduce the oxalate?
Here's the cooking hack: boil Sorrel, discard the water. That's where the dissolved oxalate goes. Expect roughly 30-50% reduction. Steaming is a distant second place.
How reliable is the data for Sorrel?
Oxalate: very reliable (Harvard 2024 lab measurement). Other nutrients: still being matched to USDA data. The oxalate figure is what matters for a kidney stone decision, and that one's solid.
Can I eat Sorrel if I pair it with dairy?
Yes, it helps. Calcium from food (yogurt, cheese, milk) binds oxalate in your gut so less reaches your kidneys. With Sorrel, having dairy at the same meal is a smart move. Not supplements though — those work differently.
