🟢 Low Oxalate
Low-oxalate foods — under 25 mg per serving. Based on Harvard T.H. Chan SPH oxalate data (2024).
1019 foods in this collection
Oxalate values from Harvard T.H. Chan SPH Oxalate Database (2024), measured via ion chromatography. This site is a dietary reference tool, not a medical resource.
'Low oxalate' means under 25 mg per serving — the same threshold the site's Safe rating uses, phrased differently. The two labels are equivalent in practice. Building most of a day's eating from this range keeps the total oxalate load low without constant tracking, which is why low-oxalate lists are the practical backbone of a stone-prevention diet.

❓ Frequently Asked Questions
How many foods are rated "Low Oxalate"?
There are 1019 foods in this category in our database, all verified against Harvard T.H. Chan SPH (2024) oxalate measurements.
Should I eat foods labeled this way?
This rating is based on lab-measured oxalate from Harvard T.H. Chan SPH (2024). It's a reliable guide, but your individual tolerance depends on stone type, medication, and overall diet — discuss with your dietitian.
What does this rating mean for my kidney stone diet?
This rating comes from Harvard's 2024 oxalate measurements. It helps you make informed choices, but it's one data point. Your overall diet pattern matters more than any single food.
Can I trust this label?
Yes — this isn't an opinion or guess. The rating uses Harvard lab measurements of oxalate content. That said, how your body handles oxalate varies by individual.
This is dietary reference information, NOT medical advice. Talk to your doctor or a registered dietitian before changing your diet. Oxalate tolerance varies by person, stone type, and medication.
