Tools (4)
🟢check_food(barcode, query, country)
Looks up a packaged food or drink in Open Food Facts (3M+ products) by barcode or by name and returns a 0-100 health score (Excellent / Good / Poor / Bad) with the reasons: nutrition (Nutri-Score), additives and their risk level, and how processed it is. For questions such as whether a product is healthy. A barcode gives the most precise match.

}🟢analyze_label(product_name, brand, ingredients_text, nutrition, is_drink, ...)
Scores a food from its label: the ingredient list and/or the nutrition facts, for example from a photo of the packaging or pasted text, including products that aren't in the database. Most accurate with the ingredient list exactly as printed, including E-numbers and words in brackets. Nutrition values can be per 100 g or per serving (with the serving size). Returns the same 0-100 score and reports any missing data.
