Sarah is the data editor at OxalateWatch. She curates and verifies the food composition values on the site — oxalate, sodium, calcium, and protein — against the Harvard T.H. Chan School of Public Health oxalate database (2024) and USDA FoodData Central, where every value is traceable to a specific USDA FDC ID. Her work is the reason each food page carries a measured number rather than an estimate.
Before OxalateWatch, Sarah spent over a decade as an editor and data researcher working with nutrition and food-composition datasets, where accuracy checking across large spreadsheets was the daily job. She has a background in data journalism and editorial fact-checking, and she treats a food page the way a fact-checker treats a quote: every number has a source.
Every page on this site is a dietary reference tool. See how oxalate values are measured and verified on our data methodology page.
