Nutri-Score
The A–E nutrition grade used on Spanish and French packaging. Cuadra maps it to 0–100 and gives it 60% of the product score.
NOVA
A four-group classification of food processing, from unprocessed (group 1) to ultra-processed (group 4). It contributes 30% of the product score.
Additive risk level
Cuadra groups additives into high and moderate risk using EFSA re-evaluations. Each high-risk additive costs 15 points and caps the product at 49; each moderate one costs 3 points.
Canonical ingredient
The recipe-level ingredient before it becomes a product: “spinach”, not “Espinacas 300 g”. Recipes are written in canonical ingredients so any store’s products can satisfy them.
SKU
A specific product in a specific pack, with one price. It is the thing that actually goes in the basket.
Pack chaining
Using one pack across several meals before it spoils. A 300 g bag of spinach used on Tuesday and again on Friday is chained; buying two bags is not.
Remainder
What is left of a pack after a meal uses part of it. Remainders are tracked per shopping trip and expire at the ingredient’s shelf life once opened.
Shopping trip
The window between shops. A 30-day plan splits into weekly trips, and remainders and waste are counted per trip.
Budget fitting
The step that keeps the basket under your maximum. If the plan overshoots, it swaps the most expensive slot for its best cheaper alternative until it fits, or reports the overshoot.
Dish health
The quantity-weighted mean of a dish’s non-pantry products’ scores. Pantry staples are excluded so salt and oil do not dominate the result.
