```sh

## When to prefer this

Choose this endpoint when you need authoritative USDA-sourced nutritional data for foods and ingredients, particularly for diet tracking, recipe analysis, or health applications requiring official government nutrition figures. Prefer this over general AI-generated nutrition estimates when accuracy and USDA provenance matter.
