What Is Considered Ultra Processed Food? The 5-Sign Test

A food is considered ultra-processed when it meets a specific technical definition, not when it merely seems junky. Under the NOVA system, the criterion is that the product is an industrial formulation made mostly from substances derived from foods, oils, fats, sugars, starches, protein isolates, together with additives whose purpose is to imitate the sensory qualities of real food or disguise the qualities of the formulation. Carlos Monteiro's research group, which authored the definition, adds a memorably blunt shortcut: if a product contains ingredients you would not find in an ordinary home kitchen, it is considered ultra-processed.

That definition converts into a five-sign test you can run at the shelf. Sign one: food fractions instead of foods, ingredients like wheat starch, whey protein concentrate, palm kernel oil, and dextrose, which are pieces extracted from crops rather than the crops themselves. Sign two: cosmetic additives, meaning any dye, flavoring, flavor enhancer, sweetener, emulsifier, thickener, or foaming, anti-caking, and glazing agent. Sign three: the phrase natural and artificial flavors, which signals the taste was engineered rather than inherent. Sign four: an ingredient count above roughly five paired with names requiring a chemistry background. Sign five: properties impossible in home cooking, a bread soft for three weeks, a snack cake that never stales, a neon color no plant produces.

A crucial subtlety is that classification is binary at the additive level. One marker ingredient is enough. Yogurt with added carrageenan is considered ultra-processed even though yogurt itself is a minimally processed food; the same applies to a wholegrain bread that includes a single emulsifier. This strictness surprises people, but it is what makes the system testable, and it explains why two visually identical products can be classified differently. The judgment is always about the formulation in front of you, never the category it belongs to, and the surrounding groups that a product might fall into instead are mapped in our NOVA classification overview.

Applying the test to borderline cases shows how it works in practice. Is granola considered ultra-processed? Oats, honey, nuts, and oil baked at home: no. A commercial version with soy lecithin, natural flavor, and brown rice syrup: yes, three separate signs fire. Is dark chocolate considered ultra-processed? Cocoa mass, cocoa butter, and sugar passes the test; add vanillin and PGPR, an emulsifier, and it fails. Is sparkling water considered ultra-processed? Plain, no; citrus-flavored with sucralose, yes, on the sweetener alone. The test resolves cases a mental junk-food category cannot.

Be aware of what the definition deliberately ignores, because this is where most confusion originates. Calories, sugar grams, fat, and protein are irrelevant to the classification; a zero-calorie diet soda is emphatically considered ultra-processed while butter, pure fat, is not ultra-processed at all. Organic certification, non-GMO status, gluten-free claims, and added vitamins change nothing. Fortification can even be a tell, since heavily fortified products are often replacing nutrients their base materials lost to refining.

Critics note real edge cases, infant formula, some supermarket wholegrain breads, plain plant milks, where the label is considered technically ultra-processed but the evidence of harm is weaker, and the scientific debate on those margins is ongoing. For everyday shopping the test still earns its keep, because the products it flags most loudly are the ones carrying multiple ingredients to avoid at once. BerryPure runs all five signs automatically: scan a label, and the app shows the classification along with each additive from the common additives database that triggered it.
