About Ration

What Ration is

Ration is a research-driven food database and nutrition tracker. Every food page combines standard nutrient composition from USDA laboratory measurements with the compound data most nutrition sites omit: oxalate, phytate, purine, heavy-metal, and bioactive levels compiled from peer-reviewed studies, each value carrying its citations and a confidence grade.

Rankings and comparisons are computed directly from those measurements, never hand-picked. Where a food has not been measured, Ration shows a dash instead of a guess.

The dataset today

Counts are read live from the database, so they reflect the corpus as it stands today. Full methodology is documented on the dataset page.

Why it exists

Most nutrition tools stop at calories and macros. But whether a food works for you also depends on what else is in it, and on how preparation changes that. Knowing spinach is high in oxalate is only useful if you also know boiling removes a measured share of it. Ration exists to put that second layer of food science, scattered across thousands of papers, into one structured, cited, searchable place.

Who makes it

Ration is built by a small independent team, founded by Spencer Hochhaus. Data work follows the sourcing and correction practices in our editorial policy: laboratory data from USDA FoodData Central, compound values from published research, and a medical-review byline only when a credentialed reviewer has actually reviewed the piece.
