Categories used by the local food table (API key, rate-limited)

GET /foods/local-categories · API key required

The category values the local Malawi food composition table actually uses (for example `Staples`, `Animal`, `Baby foods`), each with the number of foods in it. Pass these to `/foods/by-category` or to `category=` on `/foods` and `/foods/search`. This is a different list from `GET /foods/categories`, which returns FatSecret's taxonomy and does not match the local table.
