What Counts as Ultra-Processed Food? Spot It in 10 Seconds

You’re in the cereal aisle with two boxes. Both say natural. One says made with whole grains, the other a good source of fiber. Both have a sheaf of wheat on the front.

Which one is ultra-processed? The front of the box won’t tell you. It isn’t there to.

Read the back, not the front.

The government is still working out an official definition. You don’t need to wait for it. The ingredient list and one simple question answer most of what a definition would.

Where the official definition is

In July 2025, the FDA and USDA asked the public for help defining ultra-processed food, noting that there was “no single authoritative definition” for the US food supply. A year later, on August 3, 2026, the FDA sent a proposed definition to the White House budget office for review. It is a white paper, not a regulation; the acting FDA commissioner described it as a foundation for future federal nutrition research.

As of this week, it is still under review. The budget office’s own records list two dozen meetings about it, booked through October 19, with farm groups, food companies, health advocates and university researchers.

Not everyone wants it published. Bloomberg reported in August that food company chief executives and trade groups wrote to and called the White House to delay it, arguing it would invite litigation, raise costs and hurt business. The Consumer Brands Association, which represents food makers, called the approach “fundamentally flawed, not based on sound science, and politically motivated.” The Wall Street Journal later reported that White House staff had raised concerns of their own: that the definition would cover most foods on grocery shelves and support lawsuits. An HHS spokesperson said the policy “remains under interagency review and has not been finalized.”

One state didn’t wait. California’s law, signed in October 2025, is the first in the country to define ultra-processed food in statute — for school food only, which it phases them out of between 2029 and 2035.

Whatever you make of that fight, notice where it leaves you: in the aisle, today, with two boxes and no official answer.

The back of the box is the part with rules

The words on the front of a package are mostly marketing. Take natural: the FDA has never set a formal definition for it.

The ingredient list is different. Federal rules require every ingredient to be listed by its common name, in order of weight, most first. Certified colors such as Yellow 5 and Yellow 6 have to be named individually.

Those rules have teeth. Last month, PepsiCo began recalling 122,021 cases of 28-ounce Gatorade — Lemon Lime, Orange and their Zero versions — sold in 37 states, because the bottles contained Yellow 5, Yellow 6 or both, and the label didn’t say so. The FDA classified it as a Class II recall on October 2. The dyes are approved for use in food. Leaving them off the list was the problem, partly because, as the FDA notes, Yellow 5 can cause itching and hives in some people.

The list isn’t perfect. “Natural flavor” or “spices” can stand in for a whole set of substances, so a list can still keep a few secrets. But unlike the front of the box, it’s written to rules, not to sell.

The kitchen test

The term “ultra-processed” comes from NOVA, a food classification devised by researchers in Brazil. Its authors offer a practical way to identify one: check whether the ingredient list contains at least one item you wouldn’t find in a home kitchen. Those come in two kinds.

  • Industrial ingredients, made from food but rarely or never used in a kitchen: high-fructose corn syrup, maltodextrin, dextrose, invert sugar, hydrogenated or interesterified oils, hydrolyzed proteins, soy protein isolate.
  • Additives that make the product look, taste or feel more appealing: flavors, flavor enhancers, colors, emulsifiers, sweeteners, thickeners, and gelling or glazing agents.

Find even one, and by NOVA’s definition the food is ultra-processed. According to Bloomberg’s reporting, the federal draft leans on a similar question: whether a product contains ingredients that aren’t commonly used in home kitchens.

That’s why it takes ten seconds. You aren’t reading the whole list. You’re scanning for one word that doesn’t belong in a kitchen.

Why it’s worth the ten seconds

In a 2019 NIH study, 20 adults lived on a research ward for four weeks, spending two weeks on an ultra-processed diet and two on an unprocessed one, and eating as much or as little as they liked. On the ultra-processed diet they ate about 500 more calories a day, and gained about two pounds. On the unprocessed diet, they lost about two.

A 2025 trial in England went further. Fifty-five adults spent eight weeks on each of two diets that both met UK healthy-eating guidelines, one built from minimally processed foods and one from ultra-processed ones. They lost about twice as much weight on the minimally processed diet — roughly 2% of body weight against 1%.

Large reviews of observational studies have also linked diets high in ultra-processed food to a range of worse health outcomes, though that kind of evidence shows association, not cause.

This isn’t a purity test

By the kitchen test, a supermarket whole-grain loaf with one emulsifier counts as ultra-processed, and so does a can of soda. They are not the same food. California’s law draws the same distinction: it only targets ultra-processed foods that are also high in saturated fat, sodium or added sugar, or that contain non-nutritive sweeteners.

So don’t empty the pantry. The point isn’t to eat nothing that fails the test. It’s to know which of the things you eat every day do, and to change the one that matters most.

Do This Week

You don’t need a federal definition to make a better choice on your next grocery run. Three steps:

  • Turn over the three packaged foods your household goes through fastest. Cereal, bread, yogurt, snack bars, drinks — whatever empties first.
  • Mark anything you wouldn’t find in a kitchen. Flavors, colors, emulsifiers, sweeteners, syrups and isolates.
  • Swap the one you eat most often for a version whose list reads like a recipe: plain yogurt with fruit stirred in, plain oats, bread with five ingredients instead of fifteen.

Read the back, not the front.
