Recent scientific debates are questioning whether the degree of industrial manufacturing is the true driver of poor health outcomes, or if the problem lies in what these foods contain. While ultraprocessed foods (UPFs) are frequently linked to chronic issues like diabetes and heart disease, new evidence suggests that the classification of a food as "ultraprocessed" does not always predict its nutritional quality.

Is processing the primary health risk?

For years, the NOVA classification system has been used to group foods based on how much they are industrially altered. This system often labels items containing additives like emulsifiers or sweeteners as ultraprocessed. However, researchers are finding that this category is incredibly diverse.

While some UPFs, such as sugary drinks and processed meats, are strongly linked to cardiovascular problems, others appear to be neutral. For instance, studies have shown that certain ultraprocessed items like whole-grain breads, yogurts, and some breakfast cereals may not increase metabolic risks. This suggests that the specific nutrient profile—including levels of fiber, sodium, and saturated fat—is a more accurate indicator of health impact than the processing method itself.

The complexity of food classification

Defining what constitutes an ultraprocessed food is a subject of ongoing scientific and political debate. These foods are generally understood to be industrially manufactured products made with ingredients or additives, such as flavors, colors, or thickeners, that are not commonly used in home cooking.

Because the definition can change depending on the specific ingredients used, it can be difficult for consumers to navigate. Some experts argue that focusing solely on the level of processing simplifies a complex issue and might inadvertently steer people away from helpful foods. For example, certain medical nutrition products or infant formulas are technically ultraprocessed but are essential for specific health needs. This complexity has led to a push for clearer standards, with the USDA and FDA working toward a formal federal definition in the United States.

How do UPFs impact the grocery aisle?

In the United States, ultraprocessed products are a dominant force in the food market. A recent analysis of more than 40,000 grocery items revealed that UPFs account for approximately 75% of all food and beverage sales. In some sectors, the reliance on these products is even higher:

  • Cereals: 92% of category sales are ultraprocessed.
  • Snack foods: 75% of category sales are ultraprocessed.

Despite this prevalence, being labeled as ultraprocessed does not automatically mean a product is low in nutrients. Some UPFs were found to have nutrient density scores equal to or even higher than their less-processed counterparts in the same category.

FAQ

What exactly is an ultraprocessed food?

These are industrially manufactured products that typically contain ingredients or additives, such as flavors and thickeners, that are not commonly used in home cooking.

Are all ultraprocessed foods bad for you?

Not necessarily, as some processed items like fortified cereals or certain yogurts may have nutritional profiles that are considered healthy or neutral by researchers.
