Methodology

Data sources

AI does one job in EquiliEat: recognising the food in your photo and estimating how much there is. Every number after that comes from the published, public sources below.

Nutrition — CIQUAL 2025

Energy, protein, sugars, fat, saturated fat, fibre and salt for 3,400+ foods come from the French national food composition table.

Environmental impact — AGRIBALYSE 3.2

Each food's life-cycle environmental footprint, including the carbon footprint we show as kilograms of CO₂e.

Packaged products — Open Food Facts

When you scan a barcode, the product's details come from Open Food Facts, a free, collaborative database of food products built by contributors around the world. When a product's grade comes from Open Food Facts, the app labels it "from Open Food Facts".

Open Food Facts world.openfoodfacts.org The database is available under the Open Database License (ODbL); its individual contents under the Database Contents License; product images under CC BY-SA.

The Health score

The Health score is based on the Nutri-Score 2023 algorithm. It weighs energy, sugars, saturated fat and salt against fibre, protein, and fruit, vegetables and legumes, and grades the meal from A to E.

For a few components, the published tables give only the start and end of the points scale, not the steps between. There, we interpolate evenly, so a score close to a grade boundary may differ slightly from an official Nutri-Score.

EquiliEat is not affiliated with or endorsed by Santé publique France or the Nutri-Score owners, and doesn't use the Nutri-Score logo.

The Eco score

The Eco score is EquiliEat's own environmental score, from A to E. It's calculated from each food's AGRIBALYSE footprint, weighted by how much of the meal that food makes up. The meal's CO₂e is shown next to it, in kilograms.

When data is missing

Not every food has every value. When one is missing, EquiliEat scores with what it has and says so — "based on 4 of 5 ingredients" — instead of treating the missing value as zero.

Your goals

Your daily targets are calculated from your age, sex, height, weight, activity and goal. Each one links in the app to the source below.

Energy National Academies of Sciences, Engineering, and Medicine. Dietary Reference Intakes for Energy (2023).
Protein and fibre Institute of Medicine. Dietary Reference Intakes, macronutrient reference tables.
Protein, if you're active International Society of Sports Nutrition. Position Stand: Protein and Exercise (2017).
Total fat, sugars and salt World Health Organization. Healthy diet fact sheet.
