Oxalate.org
Oxalate.org is a straightforward reference database created by a kidney stone patient to compile scattered oxalate content data into one searchable location. The site provides oxalate values for over 750 foods, drawing from reputable sources including Harvard T.H. Chan School of Public Health, USDA reports, Food Standards Australia New Zealand (NUTTAB), and peer-reviewed research. While the interface is basic, the comprehensiveness and transparent sourcing make it a practical tool for practitioners and clients managing oxalate intake for conditions like kidney stones, vulvodynia, or certain inflammatory issues. Oxalate.org offers a searchable table showing each food’s serving size, oxalate content, and original data source, making it easy to compare foods and identify high-oxalate items to avoid or low-oxalate alternatives.
