How to Spot Ultra-Processed Food on Labels
Food labels can be confusing, but with a few key skills, you can quickly identify ultra-processed foods at the supermarket. Here's your practical guide to becoming a label detective—and what to do when there's no label to read.
Key Takeaways
- Long ingredient lists (5+ items) often signal ultra-processing
- Watch for ingredients you wouldn't find in a home kitchen
- Emulsifiers, flavor enhancers, and colorings are red flags
- Health claims on packaging often mask poor nutrition
- For meals without labels, use UPFScore to scan and analyze
The Ingredient List is Your Best Friend
Forget the front of the package—that's marketing. The real story is in the ingredient list on the back. Here's what to look for:
Red Flag Ingredients
- • High-fructose corn syrup
- • Hydrogenated oils
- • Maltodextrin
- • Emulsifiers (lecithin, mono/diglycerides)
- • Artificial colors (Red 40, Yellow 5)
- • Flavor enhancers (MSG, yeast extract)
- • Protein isolates
Signs of Minimal Processing
- • Short ingredient list (under 5)
- • Ingredients you recognize
- • Whole food names (wheat, tomatoes, olive oil)
- • Simple preservatives (salt, vinegar, citric acid)
- • No added sugars or their derivatives
- • No artificial anything

Count the Ingredients
More than 5? Proceed with caution. More than 10? Likely ultra-processed.
Scan for Unknowns
If you can't pronounce it or wouldn't cook with it at home, that's a warning sign.
Check Sugar Position
Ingredients are listed by weight. If sugar (or its aliases) appears in the first 3, reconsider.
Sugar's Many Disguises
Sugar goes by over 60 different names on labels. Here are the most common ones to watch for:
Common sugar aliases: Sucrose, glucose, fructose, dextrose, maltose, corn syrup, high-fructose corn syrup, agave nectar, cane juice, fruit juice concentrate, brown rice syrup, barley malt, coconut sugar, maple syrup, honey (when added), molasses, and anything ending in "-ose."

Frequently Asked Questions
What's the fastest way to spot UPF in the store?
Check the ingredient list length first. If it has more than 5 ingredients and includes words you don't recognize, it's likely ultra-processed. Also look for additives like emulsifiers (e.g., lecithin), flavor enhancers (e.g., MSG), and artificial colors.
Are all packaged foods ultra-processed?
No. Many packaged foods like frozen vegetables, canned beans, dried pasta, and plain nuts are minimally processed. The key is checking the ingredients—if it's just the food itself with minimal additions, it's not UPF.
Can 'natural' or 'organic' foods be ultra-processed?
Yes. Marketing terms like 'natural,' 'organic,' or 'no artificial flavors' don't mean a product isn't ultra-processed. Organic chips or natural sodas can still be UPF. Always read the ingredient list.
What about restaurant food with no labels?
This is where UPFScore helps. Snap a photo of your meal and get an instant estimate of how processed it is—no ingredient list required.
