Where our nutrition numbers come from

The calories, macros and micronutrients in GlucoPlot's ingredient catalogue are drawn mainly from published national food-composition tables — the lab-analysed references that dietitians and researchers use.

We use USDA's FoodData Central wherever possible, because it is the reference most nutrition tools agree on. For some ingredients USDA does not cover, we use other published national references.

The catalogue is reviewed and updated over time, so the foods it covers, the figures and the references we draw on may change between app versions.
