A landmark global study reveals that ultra-processed foods (UPFs) may be responsible for up to 14% of preventable premature deaths in high-consumption countries—calling for urgent changes to public health policies and dietary guidelines worldwide.
Key Points at a Glance
Study links higher UPF consumption to increased all-cause premature mortality.
Each 10% increase in UPF intake raises risk of death by 3%.
In 2018, UPFs were linked to 124,000 premature deaths in the U.S. alone.
32 diseases have been associated with UPFs, including heart disease, cancer, and depression.
Researchers call for global policy action to reduce UPF consumption.
In a sweeping international study, scientists have uncovered the staggering impact of ultra-processed foods (UPFs) on global health—linking their growing consumption to hundreds of thousands of preventable, premature deaths each year. The findings, published in the American Journal of Preventive Medicine, spanned eight countries and provide the clearest warning yet: UPFs are not just unhealthy, they’re deadly.
UPFs are industrially formulated products made largely or entirely from ingredients not found in home kitchens—extracted, synthesized, or chemically modified compounds that include artificial flavors, emulsifiers, colorants, and preservatives. These foods, which include many packaged snacks, sodas, instant meals, and fast food items, have been steadily replacing traditional, minimally processed meals around the world.
Led by Dr. Eduardo Nilson of the Oswaldo Cruz Foundation in Brazil, the study modeled dietary and mortality data from nations including Australia, Brazil, the U.K., the U.S., and Mexico. It showed that for every 10% increase in UPFs as a share of a person’s daily calorie intake, the risk of death from any cause rose by 3%. That might seem modest—until scaled to national populations.
In the United States, where over 50% of the average diet is made up of UPFs, the model attributed around 124,000 deaths in 2018 alone to their consumption. By comparison, countries like Colombia—where UPFs make up only 15% of dietary intake—had significantly lower attributable mortality rates. Yet even there, the risk is growing as global food systems shift toward industrialized production and convenience.
The health risks linked to UPFs are as vast as they are alarming. A total of 32 diseases have been associated with high UPF intake, from cardiovascular disease and obesity to diabetes, some cancers, and even depression. Crucially, the study was the first to quantify the share of all-cause premature deaths linked directly to these foods, rather than focusing on individual dietary components like sugar or sodium.
Dr. Nilson warns that while UPF consumption has plateaued in many high-income countries, it is rapidly rising in low- and middle-income nations. This trend threatens to escalate health crises in regions that are already facing nutritional and healthcare challenges. “Global policies that disincentivize the consumption of UPFs are urgently needed,” he said, “especially ones that promote traditional dietary patterns rooted in fresh, minimally processed foods.”
The researchers advocate for systemic changes—not only in dietary guidelines but also in how governments regulate the marketing, labeling, and affordability of UPFs. Strategies could include taxation, advertising restrictions (especially targeting children), and incentives to make healthier foods more accessible.
This research joins a growing body of evidence suggesting that the impact of food processing itself—beyond just the nutrient content—is a major determinant of health. It also affirms a key message echoed by nutritionists worldwide: what we eat is not just a matter of personal choice, but of public health strategy.
