What is a processed food score? Low to Very high

A processed food score is a short label for how much industrial processing went into what you are holding. It is not a calorie count, a Nutri-Score, or a “healthy / unhealthy” grade. It answers one question: how close is this to food you could make yourself?

Where the idea comes from

Researchers often group foods with the NOVA system: unprocessed or minimally processed, culinary ingredients, processed foods, and ultra-processed foods. That research language is precise and easy to misuse on a phone screen. Gut Score keeps the same idea and drops the numbering. You see Low, Medium, High, or Very high — a NOVA-style processed score in plain English.

What each label means

• Low — mostly whole ingredients. Fruit, plain yogurt, oats, eggs, a piece of fish. Minimal processing, if any.
• Medium — some processed ingredients. Foods that use culinary extras (oil, sugar, salt) or light industrial steps, still recognisable as food.
• High — more industrial processing. Longer lists, more factory steps, further from a home recipe.
• Very high — ultra-processed. Industrial formulations: flavourings, emulsifiers, reconstituted parts. Worth a second look before it becomes a habit.

The labels are honest, not moral. Bread can be Medium. A protein cookie can be Very high. You decide what to do with the information.

What Gut Score shows on a scan

Gut Score shows this processed score plus kcal. One glance covers processing and energy for the item in your hand. Log the meal and both numbers roll into the day: a running kcal total and a daily processed score for everything you have saved so far.

That pairing matters. A Low-score food can still be energy-dense. A Very high snack can be small. Seeing only one number hides the other half of the decision. The scan screen keeps them together.

What a processed score is not

• It is not a calorie app that happens to mention processing. Kcal sit next to the score; they do not replace it.
• It is not a general health score that mixes additives, organics, and nutrients into one percentage. That is closer to how Yuka rates products. See Yuka vs Gut Score.
• It is not medical advice. The score describes processing. It does not diagnose a diet.

How to use it in real life

Use the score to compare two similar packs, not to ban a food group. Swap when you can. Log when you eat it anyway. The daily processed score is there so one Very high treat does not get mistaken for a Very high day — and so a string of “fine” scans does not hide a pattern. If you want the app that puts this score on every scan, start with the best app for finding processed foods.
