137 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.
Caution-rated foods sit in the 25-99 mg oxalate range per serving — above the safe threshold but below the high-risk zone. They are not off-limits; they are portion foods. The pattern that works: smaller servings, less frequent rotation, and pairing with a calcium-rich food at the same meal so less oxalate reaches the kidneys. For patients tracking a daily oxalate budget, caution foods are where the arithmetic matters most.
