Summary
The Shopping List Nutrition Matcher parses one food item per line, normalizes text deterministically, maps each line to the closest food match in the local food database, and totals nutrition from selected matches.
How it works
- Parse list lines.
- Normalize terms (case, punctuation, plurals, common synonyms).
- Rank food candidates by deterministic token overlap scoring.
- Let users adjust each matched item and portion grams.
- Sum totals for calories, macros, and sodium/salt.
Sodium and Salt
The calculator shows sodium in mg and salt equivalent in g:
salt(g) = sodium(mg) / 1000 × 2.5- UK benchmark shown in UI: max 6g salt/day (about 2400mg sodium/day).
Assumptions
- Matching is deterministic and local (no LLM calls).
- Totals depend on selected candidate and portion size.
- Database values are USDA-based reference food values.
