UPFScore Accuracy and Limitations
We believe in transparency. Here's an honest look at what UPFScore can do well, where it has limitations, and how to get the best results.
Key Takeaways
- UPFScore provides estimates, not exact measurements—use it as a helpful guide, not absolute truth
- The AI works best with clearly visible, well-lit meal photos
- Homemade vs store-bought versions of the same dish may score differently in reality
- Edge cases include mixed dishes, unusual cuisines, and heavily garnished plates
What UPFScore Does
In short: UPFScore uses AI image recognition to estimate the ultra-processed food content of your meals. It's a helpful awareness tool, not a laboratory analysis.
When you take a photo with the UPFScore app, our AI identifies the visible foods and estimates their processing level based on the NOVA classification system. The result is a simple 1-4 score that gives you a quick read on how processed your meal is.
What Works Well
UPFScore is Good At
- ✓Identifying common foods: Standard meals, recognizable ingredients, typical restaurant dishes
- ✓Distinguishing processing levels: Fresh vegetables vs processed snacks, whole grains vs refined products
- ✓Tracking patterns: Showing trends in your eating habits over time
- ✓Building awareness: Helping you notice which foods are more processed than expected
- ✓Clear, well-lit photos: Standard meal presentations with visible ingredients

UPFScore May Struggle With
- !Hidden ingredients: Sauces, dressings, and seasonings that aren't visible in the photo
- !Homemade vs store-bought: A homemade pizza and a frozen pizza may look similar but differ greatly in processing
- !Mixed or blended dishes: Smoothies, stews, and casseroles where ingredients aren't distinguishable
- !Regional or unusual cuisines: Less common dishes that the AI hasn't seen many examples of
- !Poor photo quality: Dark, blurry, or poorly framed images
- !Beverages: Especially in opaque containers where contents aren't visible
How to Get the Best Results
- Use good lighting. Natural light or well-lit environments work best.
- Capture the whole meal. Include all items you're eating in the frame.
- Shoot from above. A top-down angle usually shows ingredients most clearly.
- Separate items if possible. Plated meals with distinct items score more accurately than mixed bowls.
- Be honest with yourself. If you know your "homemade" sauce came from a jar, factor that into your interpretation.
Using UPFScore Wisely
UPFScore is designed to be a helpful guide, not the final word on your diet. Here's our recommended approach:
- Focus on patterns, not individual scores. One meal doesn't define your diet—weekly trends matter more.
- Use it for learning. When a score surprises you, investigate why. It's a chance to learn about food processing.
- Don't stress about perfection. A score of 2 instead of 1 is not a failure. Progress matters more than perfection.
- Combine with your own knowledge. You know things about your meal that the camera can't see.

Frequently Asked Questions
How accurate is UPFScore?
UPFScore provides useful estimates based on AI image recognition and the NOVA classification system. It's accurate enough to help you identify patterns and make better choices, but it's not a laboratory analysis. Think of it as a helpful guide rather than an exact measurement.
Why might the same meal get different scores?
Variations in lighting, angle, and what's visible in the photo can affect results. Additionally, the AI can't see hidden ingredients—a homemade sauce and a store-bought sauce may look identical but have very different processing levels.
What foods does UPFScore struggle with?
The AI may have difficulty with: heavily mixed dishes where individual ingredients aren't visible, unfamiliar or regional cuisines, foods that look similar but have different processing levels (like homemade vs instant mashed potatoes), and beverages in opaque containers.
Should I rely on UPFScore for medical decisions?
No. UPFScore is an educational and awareness tool, not a medical device. It's designed to help you become more aware of ultra-processed food in your diet, not to provide medical nutrition advice. Always consult healthcare professionals for medical decisions.
