How we score
Scores and warnings rely only on what the product label says and on public scientific classifications. We never guess missing information.
The SnackCheck score
The score uses the 2023 update of the Nutri-Score algorithm used in Europe, per 100 g/ml: energy, sugars, saturated fat and salt add negative points; fibre, protein and the fruit-vegetable share add positive points. The official special rules apply to beverages, fats and nuts, cheese and red meat.
- A → 85–100 points
- B → 70–84 points
- C → 40–69 points
- D → 20–39 points
- E → 0–19 points
If energy, sugars, saturated fat or salt is missing we don't score the product; it says "not scored".
Carcinogenic and banned additives
We match the E-numbers and additive names in the ingredient list with the classification of IARC, the World Health Organization's cancer agency, and with EU additive law.
- IARC Group 1 — carcinogenic to humans.
- IARC Group 2A — probably carcinogenic to humans.
- IARC Group 2B — possibly carcinogenic to humans.
- Banned for use in food in the European Union.
A product with one of these flags scores at most 39; the product page says why.

Allergens
We look for the 14 allergens of EU Regulation 1169/2011 (aligned with the Turkish Food Codex) in the ingredient text. "May contain" and "traces of" statements are shown separately as trace warnings.
We never treat a product with no ingredient list as "allergen-free".

Traffic lights
The low/medium/high colours for fat, saturated fat, sugars and salt follow the UK Food Standards Agency's front-of-pack thresholds, with separate thresholds for drinks.

Personal evaluation
Each product is marked suitable, caution, not suitable or unknown according to your health profile. A product containing your allergen or conflicting with your diet is "not suitable"; with diabetes, high blood pressure or high cholesterol we warn when sugar, salt or saturated fat is high.
Each warning lowers your personal score by 15; a product that is not suitable gets a personal score of 0.
Data sources
Product information comes from pages published by manufacturers and shops. A product is matched only by its real barcode; we never invent barcodes. The same product from different shops is kept as one record.
Some product information comes from: Open Food Facts, ODbL 1.0
For information only, not medical advice. Always check the product label for allergies.
