The short answerUltra-processed foods are industrial products made mostly from substances extracted or refined from foods, often with additives such as flavorings, emulsifiers or colors that you wouldn't use in a home kitchen. Examples include soft drinks, packaged snacks, many breakfast cereals and processed meats. Eating them less often is a practical goal, not an all-or-nothing rule.

Ultra-processed foods are industrially made products built mostly from ingredients extracted or refined from whole foods, such as starches, oils, sugars and protein isolates, often combined with additives like flavorings, emulsifiers, sweeteners or colors. Think soft drinks, packaged snack cakes, many breakfast cereals, instant noodles and processed meats. They’re convenient and widely eaten, and the most practical goal is to make them a smaller part of your week rather than to banish them.

The NOVA system: four levels of processing

The most widely used way to group foods by processing is the NOVA classification, developed by researchers at the University of São Paulo in Brazil. It sorts foods into four groups:

NOVA group	What it means	Examples
1. Unprocessed or minimally processed	Whole foods, sometimes cleaned, frozen, dried, ground or pasteurized	Fresh or frozen vegetables, fruit, plain milk, eggs, rice, dried beans, plain oats, unsalted nuts
2. Processed culinary ingredients	Substances taken from foods and used in cooking	Olive and vegetable oils, butter, sugar, salt, honey
3. Processed foods	Group 1 foods with group 2 ingredients added, made with simple methods	Canned vegetables in brine, cheese, simple fresh bread, canned fish, salted nuts
4. Ultra-processed foods	Industrial formulations with ingredients rarely used in home cooking	Soft drinks, packaged cookies and chips, sweetened cereals, instant soups, hot dogs, many ready meals

The line between groups 3 and 4 is where most confusion happens. A loaf made from flour, water, yeast and salt counts as processed. A packaged loaf that also contains emulsifiers, added sugars and preservatives is usually considered ultra-processed.

Why researchers are paying attention

A large body of observational research has linked diets high in ultra-processed foods with higher risks of several health problems, including weight gain, type 2 diabetes and heart disease. Observational studies can’t prove cause and effect on their own. However, a small, tightly controlled study at the National Institutes of Health found that people ate more calories when offered an ultra-processed diet than when offered a minimally processed one matched for nutrients like sugar, fat and fiber.

Scientists are still working out why. Possible reasons include:

Many ultra-processed foods are soft, quick to eat and easy to overeat before fullness signals catch up.
They’re often high in added sugar, sodium and refined starch and low in fiber.
They can crowd out vegetables, beans, whole grains and other nutrient-rich foods.

There’s also lively debate about how much of the effect comes from processing itself and how much from the nutrient profile of these products.

How to spot them on the shelf

You don’t need a chemistry degree. A few clues help:

Read the ingredient list. Items you wouldn’t find in a home kitchen, such as high-fructose corn syrup, hydrogenated oils, protein isolates, maltodextrin, flavor enhancers, emulsifiers or artificial colors, signal ultra-processing.
Notice the length. A long list isn’t automatically bad, but it often goes hand in hand with heavy processing.
Look past health claims. Phrases like “natural,” “protein-packed” or “made with real fruit” say nothing about how processed a product is.
Check the Nutrition Facts panel for added sugars and sodium, which our guides to added sugar and sodium explain.

Not all ultra-processed foods are equal

The category is broad, and some of its members are genuinely useful. Packaged whole-grain bread, unsweetened fortified plant milks and some meat alternatives may count as ultra-processed under NOVA while still providing fiber, protein, calcium or other nutrients. A sugary soda and a fortified whole-grain cereal are not nutritional equals, even if they share a category.

Convenience matters too. Long work hours, caregiving, disability, limited kitchen space and tight budgets are real, and nobody should feel judged for relying on packaged food. The aim is progress, not purity.

Small, realistic swaps

Trade one sugary drink a day for water, sparkling water or unsweetened tea.
Choose plain oats or plain yogurt and add your own fruit and a drizzle of honey.
Keep frozen vegetables and canned beans on hand for fast, minimally processed meals.
Make a big pot of soup, chili or grain salad on the weekend; our meal prep guide shows how.
Snack on fruit, nuts, home-popped popcorn, or cheese with whole-grain crackers.
When you buy ready meals, look for ones with vegetables, beans or whole grains near the top of the ingredient list.

The bottom line

Ultra-processed foods are industrial products made largely from refined ingredients and additives, and diets heavy in them are linked with poorer health. You don’t need to eliminate them. Building most meals from whole and minimally processed foods, and picking the more nutritious options when you do buy packaged, is a balanced and realistic approach.

Frequently asked questions

Is all processed food bad for you?

No. Processing includes freezing, canning, drying, pasteurizing and fermenting, and many processed foods are nutritious, such as frozen vegetables, canned beans, plain yogurt and cheese. The concern centers on ultra-processed products, especially those high in added sugar, sodium and refined starch.

Is bread an ultra-processed food?

It depends on how it's made. Simple bread made from flour, water, yeast and salt counts as processed. Many packaged breads with emulsifiers, added sugars and preservatives are classified as ultra-processed, though whole-grain versions still provide useful fiber.

Are plant-based meat alternatives ultra-processed?

Most are, under the NOVA system, because they're made from protein isolates, oils and additives. They can still fit into a healthy diet, especially if they replace processed meats, but whole plant proteins like beans, lentils and tofu are simpler everyday choices.

How can I eat fewer ultra-processed foods on a budget?

Lean on low-cost staples like oats, rice, dried or canned beans, eggs, frozen vegetables and seasonal fruit. Cooking in batches and keeping simple snacks like popcorn kernels, peanuts and bananas on hand also helps reduce reliance on packaged foods.
