Limiting Ultra-Processed Foods: New Study Links Consumption to Premature Death
Industrial ingredients often replace nourishment and erode long-term wellbeing in meals.
Limiting Ultra-Processed Foods: A New Wake-Up Call for Health
Ultra-processed foods have become a mainstay in modern diets, regularly found in pantries and on dinner tables all over the globe. Yet, a landmark study published in the American Journal of Preventive Medicine links high consumption of these foods to a significantly increased risk of premature death. The implications of this research resonate strongly, particularly for countries like the United States and United Kingdom where ultra-processed foods dominate much of the average person’s daily calorie intake.
What Are Ultra-Processed Foods?
Understanding the definition of ultra-processed foods (UPFs) is crucial for recognizing their prevalence and hidden risks. Ultra-processed foods are industrial formulations typically containing five or more ingredients. These often include:
- Artificial flavors, colors, and sweeteners
- Emulsifiers and stabilizers for texture
- Preservatives for longer shelf life
- High amounts of sodium, fats, and added sugars
- Refined grains and processed fats and oils
Common examples include:
- Sodas and sweetened beverages
- Packaged cookies, cakes, and pastries
- Frozen dinners
- Processed meats (sausage, hot dogs, deli meats)
- Instant soups and noodles
- Mass-produced breads and breakfast cereals
- Energy, protein, and snack bars
Processed vs. Ultra-Processed: What’s the Difference?
It’s important to distinguish between different categories of food processing:
| Category | Definition | Examples |
|---|---|---|
| Minimally Processed | Foods close to their natural state; may be preserved or cut | Fresh fruits, vegetables, plain grains, milk |
| Processed | Foods containing a few added ingredients for flavor or preservation | Cheese, salted nuts, canned vegetables, fruit canned with sugar |
| Ultra-Processed | Food formulations with many ingredients, mostly artificial or refined substances | Soda, packaged snacks, frozen pizza, instant noodles, energy drinks |
The Global Study: Key Findings
Researchers analyzed dietary data across eight countries—the United States, United Kingdom, Australia, Brazil, Canada, Chile, Colombia, and Mexico—using nationally representative dietary surveys and mortality data. Their goal was to assess the link between ultra-processed food consumption and the risk of early, preventable death.
- For every 10% increase in calories from ultra-processed foods, the risk of all-cause premature death rose by about 2.7% to 3%.
- The risk climbs progressively: Moving from 10% to 20% of daily calories from these foods essentially doubles the risk.
- In the United States alone, high ultra-processed food intake was associated with over 124,000 preventable deaths each year—more than one in ten diet-related premature deaths.
- In the United Kingdom, nearly 18,000 preventable deaths annually were tied to ultra-processed foods.
Consumption Patterns by Country
| Country | Year | UPF as % of Daily Energy | Premature Deaths Linked to UPF |
|---|---|---|---|
| United States | 2017–2018 | 53.5% | 124,000+ |
| United Kingdom | 2018–2019 | 50%+ | 17,800 |
| Australia | 2011–2012 | 37.5% | n/a |
| Canada | 2016 | 43.7% | n/a |
| Chile | 2010 | 20–30% | n/a |
| Mexico | 2016 | 20–30% | n/a |
| Brazil | 2017–2018 | <20% | n/a |
| Colombia | 2015 | <20% | n/a |
What others are reading
Countries with higher overall UPF consumption (notably the U.S. and U.K.) saw the highest proportion of preventable deaths attributed to these foods.
Why Do Ultra-Processed Foods Raise the Risk of Early Death?
The direct mechanisms are complex, but researchers highlight several factors:
- Cardiometabolic Risks: High sodium, fat, sugar, and excessive calories in UPFs drive weight gain, high cholesterol, hypertension, insulin resistance, and type 2 diabetes, all major risk factors for cardiovascular disease.
- Gut and Metabolic Changes: Additives, colorants, emulsifiers, and artificial sweeteners in these foods can disturb the gut microbiome and cause systemic inflammation.
- Chemical Additives: Ingredients used for taste, texture, and shelf life—like artificial flavors and non-nutritive sweeteners—may disrupt natural metabolic processes.
- Nutritional Imbalance: Ultra-processed foods tend to displace healthier, whole foods, leading to poor intake of fiber, vitamins, and antioxidants.
Together, these effects are associated with more than thirty adverse health outcomes, ranging from heart disease and obesity to certain cancers and even mental health issues.
How Much Is Too Much? Assessing Your Diet
The study underscores that even modest increases in ultra-processed food consumption can have measurable impacts on health. For each 10% bump in UPF as a share of daily calories, your risk of early death escalates—irrespective of your country or baseline consumption level. This means that individuals consuming the most UPF in a given country, even where average consumption is lower, still face a significantly higher risk than those who consume the least.
Check your labels: If you regularly eat foods with long lists of unfamiliar ingredients, especially if you can’t recognize the food’s original form, chances are high they are ultra-processed.
Why Are UPFs So Prevalent and Appealing?
- They are inexpensive to make and convenient for busy lifestyles
- Packaged to last a long time without spoiling
- Flavor and texture enhanced to encourage repeat consumption
- Extensive advertising and prominent shelf placement
What Should You Eat Instead?
No one needs to avoid all processed foods, but minimizing exposure to ultra-processed foods and replacing them with minimally processed, nutrient-dense options can greatly improve long-term health. These strategies may help:
- Prioritize whole foods—fruits, vegetables, lean proteins, legumes, whole grains
- Choose foods with short ingredient lists
- Cook more meals at home, controlling salt and sugar
- Limit sugar-sweetened beverages and packaged snacks
- Check nutrition labels for sodium, added sugars, and unfamiliar additives
What the Experts Say
Dr. Eduardo Nilson, an author of the study and a researcher at the Epidemiological Research Center in Nutrition and Health – Nupens at the University of São Paulo, emphasizes that the link between ultra-processed food and early death is “impressive yet not unexpected,” in light of numerous previous studies finding similar impacts. Other experts highlight that the research provides concrete evidence across diverse countries and consumption levels, suggesting that reducing UPF intake could substantially lower preventable deaths globally.
Christopher Gardner, Ph.D., a nutrition scientist at Stanford University, notes: “Even in a country where only 15% of the food being sold was UPF, those consuming the most vs. the least had detectably different rates of mortality… They should get credit for adding that to our knowledge base.”
Reducing Ultra-Processed Foods: Public Health Benefits
- Countries with higher UPF intake have a larger fraction of preventable premature deaths linked to these foods.
- Public policies supporting better food labeling, restrictions on marketing to children, and availability of healthier options could reduce UPF consumption.
- Dietary Guidelines in several nations now advise limiting ultra-processed foods to protect population health.
Improvements at both the individual and societal level—through education, labeling, and regulatory action—will be essential in changing the trajectory of diet-related chronic diseases linked to UPFs.
Frequently Asked Questions (FAQs)
What exactly counts as an ultra-processed food?
Ultra-processed foods typically have five or more ingredients, many of which are industrial in origin. They include any food or drink made with artificial colors, flavors, emulsifiers, and preservatives, and often contain large amounts of added fat, sugar, and salt. Examples are sodas, packaged baked goods, instant noodles, frozen pizzas, processed meats, and many snack foods.
How quickly do health risks increase with ultra-processed food intake?
The study found that for every 10% increase in total calories from these foods, the risk of early, preventable death increases by around 3%. The risk adds up quickly as these foods replace natural, unprocessed foods in the diet.
Is it necessary to eliminate all ultra-processed foods from my diet?
No, but reducing their presence is highly beneficial. Focus on minimizing consumption, especially of items with long ingredient lists and artificial additives, and replacing them with whole or minimally processed options whenever possible.
Are all processed foods harmful?
Not all processed foods are equal. Minimally processed foods (like frozen vegetables or canned beans without added sugar/salt) can be part of a healthy diet. The health risks are concentrated in foods that are highly processed and contain many artificial or refined ingredients.
How do I spot ultra-processed foods in the grocery store?
Check the nutrition label and ingredients list. Ultra-processed foods often have long lists of ingredients, with names you may not recognize or cannot pronounce. If the product seems far removed from its original form, it is likely ultra-processed.
Takeaway: Making Healthier Choices for Longevity
The evidence is clear: high intake of ultra-processed foods is linked to a markedly higher risk of premature, preventable death—particularly from chronic diseases like heart disease and stroke. By recognizing, reducing, and replacing these foods in daily life, individuals can take powerful steps toward protecting their health and increasing their lifespan.
