Why Measuring Ultra-Processed Food Matters
Research increasingly links high ultra-processed food consumption to health issues including obesity, heart disease, and diabetes. But knowing about UPF in theory and actually tracking it in practice are different things.
Most people have no idea what percentage of their diet is ultra-processed. UPFScore bridges this gap by making the invisible visible—giving you concrete data about your meals that you can act on.
No more guessing
Instead of wondering whether your meal is healthy, get an instant score based on scientific classification.

1. Image Capture
You snap a photo of your meal using your phone camera. The app works with any angle or lighting, though overhead shots work best.
2. AI Food Recognition
Our AI model identifies the main items on your plate—chicken, rice, vegetables, sauce, bread, etc. It's trained to recognize thousands of common foods.
3. Processing Classification
Each identified item is classified by its typical processing level using the NOVA framework: unprocessed, processed, or ultra-processed.
4. Score Calculation
The app estimates the proportion of your plate that's ultra-processed and generates a simple 1-4 score, where 1 is mostly whole foods and 4 is mostly ultra-processed.
How UPFScore Relates to Scientific Measures
Researchers studying ultra-processed food use detailed dietary questionnaires and food diaries to calculate UPF percentage. This works for studies but isn't practical for daily life.
UPFScore provides a practical approximation. While it's not as precise as a research-grade dietary assessment, it gives you useful feedback that's actually usable in real life—seconds after you take a photo.
How to Use Your Score in Daily Life
Here are practical ways to use UPFScore:
- Compare similar meals: See if your homemade burger scores better than fast food
- Find your baseline: Scan your typical meals for a week to understand your starting point
- Set personal goals: Aim to reduce your average score over time
- Identify high-UPF moments: Discover which meals or snacks have the most room for improvement
- Gamify progress: Challenge yourself or family members to lower scores

Frequently Asked Questions
How accurate is the UPF score?
UPFScore provides estimates based on visual AI analysis. It's designed for practical awareness, not research-grade precision. For most users, it provides useful directional feedback—you'll know if a meal is mostly whole foods vs. mostly ultra-processed, even if the exact percentage varies.
What do the score numbers (1-4) mean?
Score 1 = Mostly whole/minimally processed foods. Score 2 = Some processed ingredients but mostly whole foods. Score 3 = Significant ultra-processed content. Score 4 = Mostly ultra-processed foods. Lower scores indicate less processing.
Can the app see ingredients I can't see?
The app estimates based on typical preparations. If your homemade burger uses whole ingredients, it may score better than a typical fast-food version. For packaged foods, the app uses typical formulations—your specific product may vary.
Does it work for all cuisines?
The AI is trained on diverse global cuisines. It works best with clearly visible, separated foods. Very mixed or unfamiliar dishes may have less accurate estimates. We're continuously improving coverage.
