In recent years, health experts, scientists, and media outlets have increasingly highlighted the dangers of ultra-processed foods (UPFs). These foods are often linked to a surge in chronic diseases in today’s society. But what exactly are UPFs? Why should you be concerned about them? Let’s delve deeper.

Defining UPFs can be surprisingly challenging. Historically, humans have modified foods such as grains through processes like milling, salting, and fermenting for better taste and preservation. The concept of ultra-processed foods was coined in the late 2000s by Carlos Monteiro at the University of São Paulo, Brazil. UPFs are those derived from breaking down whole foods into parts like sugar, fat, and fiber, which are then chemically modified and often contain various additives. Common examples include breakfast cereals, biscuits, fish fingers, ice cream, mass-produced breads, and sugary drinks.

Until recently, dietary advice focused primarily on nutritional content. We’ve been instructed to limit foods high in salt, sugar, and saturated fats while opting for fiber-rich, vitamin-packed alternatives. The UPF concept has shifted this conversation, suggesting that the level of processing matters more than just nutrient content. Countries like Brazil, Belgium, and New Zealand have revised their dietary guidelines to discourage the consumption of UPFs.

Is there substantial evidence that UPFs harm health? Research indicates that diets rich in UPFs correlate with severe health risks, including cancer, diabetes, dementia, heart disease, and obesity. However, many of these studies only show correlation, not causation. Assessing the specific impacts of diet against other lifestyle and environmental factors—like poverty and pollution—can be complex. Furthermore, many studies rely on surveys, which can lead to inaccuracies in dietary reporting.

One of the most credible pieces of evidence comes from a 2019 randomized trial. This short-term study involved 20 participants consuming diets high in either UPFs or unprocessed foods over two weeks, then switching diets. Both types matched in caloric content and nutritional composition. Participants were provided with meals and snacks, allowing them to eat freely.

The results were striking: those on UPF diets consumed around 500 additional calories daily, gaining nearly 1 kilogram over two weeks, whereas those on unprocessed diets lost just under a kilogram. This suggests that the appeal of UPFs often leads to excessive caloric intake due to enhanced flavor and palatability.

Some experts suggest that UPFs could pose other health risks, such as contamination from factory processes. Furthermore, many contain additives like emulsifiers, which may potentially be harmful. Studies indicate that UPFs can disrupt the microbiome and promote inflammation. Advocates argue for stricter regulations on UPFs, akin to those for tobacco products, including clear warnings on packaging and advertising limitations.

However, critics claim the evidence isn’t robust enough to justify such measures. They argue that the UPF classification is too broad, potentially labeling some healthy foods, like yogurt and whole-grain breads, as unhealthy. Nutrition experts often struggle to categorize foods by processing levels, leading to confusion among the public. Additionally, not everyone can consistently prepare healthy meals, and harsh criticism of UPFs might eliminate accessible nutrition options.

So, how concerned should we be about UPFs? While they do encompass many unhealthy foods and tend to encourage overeating, most individuals could benefit from minimizing UPF intake while increasing whole food consumption. However, complete avoidance is likely impractical and unnecessary. Aim to reduce intake, diversify your diet, and prepare your meals when possible—yet enjoy the convenience of ready-made options occasionally without guilt.

Understanding Ultra-Processed Foods: A Key to Preventing Premature Aging

In recent months, I attempted to coin a new term to describe the modern influences accelerating aging, such as obesity, stress, heatwaves, and environmental pollution. I suggested labeling our current situation as an “aging environment,” inspired by the commonly understood concept of an “obesogenic” environment. Unfortunately, my term hasn’t gained traction, but there’s another critical aspect that requires attention—ultra-processed foods (UPFs).

What Are Ultra-Processed Foods?

For those unfamiliar, ultra-processed foods are pre-packaged items that undergo extensive manufacturing, commonly containing refined ingredients like sugars, fats, and proteins, along with potentially harmful synthetic additives such as dyes and preservatives. Typically low in essential nutrients like fiber and vitamins, these foods are high in fat, salt, and sugar. Common examples include:

  • Microwave meals
  • Salty snacks
  • Mass-produced breads
  • Sugary drinks
  • Instant noodles
  • Ice cream and candy
  • Baked goods
  • Processed meats
  • Condiments like mayonnaise and ketchup

Rising Consumption of Ultra-Processed Foods

Over the past five decades, UPFs have increasingly dominated Western diets. In high-income countries, including the UK, over half of caloric intake now comes from these harmful foods. While the trend has plateaued in recent years, global demand for UPFs remains high, largely due to their convenience and affordability.

Health Risks Linked to UPFs

Research has consistently shown that a high intake of UPFs correlates with a range of chronic health issues, including:

  • Obesity
  • Cancer
  • Type 2 diabetes
  • Cardiovascular disease
  • Inflammatory bowel disease
  • Fatty liver disease
  • Kidney disease

Moreover, a growing body of evidence indicates that high UPF consumption increases overall mortality risk. Studies conducted in Spain, France, and the US found that individuals with the highest UPF intake were significantly more likely to die compared to those with lower consumption.

UPFs and Premature Aging

Recent research points to a strong connection between UPFs and premature aging. A 2024 study examined the diets of 16,055 U.S. adults aged 20 to 79, revealing that a higher percentage of calories from UPFs corresponded to accelerated biological aging. Specifically, every 10% increase in caloric intake from UPFs was associated with a 0.21-year increase in biological age.

Though skeptics may question the accuracy of biological age measurement, it is crucial to note that these studies compare groups rather than individuals, mitigating measurement biases. Even modest increases in biological age have been linked to higher risks of chronic disease and mortality.

Implications and Future Research

While studies like NHANES primarily snapshot dietary impacts, they suggest that UPFs contribute significantly to the aging environment alongside other factors like obesity and environmental stressors. Researchers debate whether it’s the poor nutritional quality of UPFs or the processing methods that cause accelerated aging.

Despite the unknowns, two substantial studies across diverse populations consistently link high UPF consumption to accelerated aging. The takeaway is clear: if possible, avoid ultra-processed foods.

While navigating a world saturated with UPFs is challenging, prioritizing whole, real foods remains beneficial. Let’s raise awareness and combat the aging environment we live in.

San Francisco Files Lawsuit Against 10 Ultra-Processed Food Corporations

On Tuesday, the city of San Francisco initiated legal action against 10 major food corporations, accusing them of marketing and distributing ultra-processed foods that are detrimental to human health and can lead to addiction.

The lawsuit claims these products are fueling a public health crisis in San Francisco and nationwide, burdening cities and governments with increased healthcare costs associated with diets rich in processed foods. This marks a pioneering effort to hold food corporations accountable for the widespread availability and recognized health hazards of such products.

“Scientific research on the dangers of these products has reached a critical point,” stated San Francisco City Attorney David Chiu during a news conference on Tuesday morning. He emphasized that “These items in our diets are closely linked to severe health issues and impose substantial costs on millions of Americans, as well as on municipalities and states across the nation.”

The category of “ultra-processed foods” typically includes flavored chips, sugary granola bars, and soda. These products contain synthetic ingredients, preservatives, and additives, and are frequently high in saturated fats, sodium, and sugar. Research has associated these foods with: increased risks of obesity, diabetes, and cardiovascular illness, along with premature death and other health issues.

Filed in San Francisco County Superior Court, the lawsuit asserts that the companies were aware these products were “unsafe for human consumption” and employed “misleading strategies” to market and sell their items.

The defendants include Kraft Heinz Company, Mondelez International, Post Holdings, The Coca-Cola Company, PepsiCo, General Mills, Nestlé USA, Kellogg, Mars Incorporated, and ConAgra Brands.

NBC News reached out to each of the companies for their comments; however, no immediate responses were received.

Sarah Gallo, senior vice president of product policy at the Consumer Brands Association, a trade group representing major food and beverage brands, stated, “The makers of America’s trusted household brands are helping Americans make healthier choices and enhance product transparency.”

Gallo further noted, “Currently, there is no agreement on the scientific definition of ultra-processed foods, and any attempts to label processed foods as unhealthy, or to vilify them by overlooking their complete nutritional value, misleads consumers and worsens health disparities. Companies adhere to stringent, evidence-based safety standards established by the FDA to offer safe, affordable, and convenient products that consumers rely on daily. Americans deserve information grounded in sound science to make optimal health choices.”

This lawsuit emerges amid growing scrutiny of ultra-processed foods from across the political spectrum. Secretary of Health Robert F. Kennedy Jr. has criticized these foods, making them a central element of his “Make America Healthy Again” initiative, which includes a proposal to ban artificial colors from the food supply within the next year.

Now, attorneys in California cities recognized for their progressive stances are also addressing this matter.

Laura Schmidt, a professor at the Health Policy Institute at the University of California, San Francisco, commented on the bipartisan trend: “Regardless of the motivation, we share a common goal. This issue has not traditionally been politicized.”

She added, “Until now, it felt like we were observing a slow-motion train wreck. I’ve been discussing childhood diabetes for decades. The rates continue to escalate. Pediatric fatty liver disease and childhood obesity—it’s evident that there is a significant problem with this segment of our food supply.”

Ms. Schmidt expressed disagreement with the industry group’s claim that there is no scientific basis for the term “ultra-processed” foods.

She remarked that the city attorney’s lawsuit resembles those previously filed against the tobacco industry.

“I feel encouraged whenever I witness public officials like the San Francisco city and state-level attorneys engaging in litigation, as this is what captured the attention of tobacco companies in the 1990s,” said Schmidt. (Notably, tobacco giants Philip Morris and RJ Reynolds acquired several food companies in the 1980s; Philip Morris acquired Kraft Foods in 1988 and spun off the brand in 2007.)

Barry Popkin, a nutrition professor at the University of North Carolina, noted that ultra-processed foods began infiltrating the U.S. market in the 1980s and have since become pervasive. Researchers began examining their detrimental health effects approximately 10 to 15 years ago, he added.

“Currently, around 75% to 80% of children’s diets consist of ultra-processed foods, while 55% to 60% of adults’ diets are similarly comprised,” Popkin stated. “It’s impossible to draw comparisons between eating habits during World War II, post-war, and the subsequent decades to today’s dietary norms.”

Last month, the scientific journal The Lancet published a thorough review of the health ramifications of ultra-processed foods, analyzing hundreds of studies along with national food survey data.

The review’s authors indicated that globally, ultra-processed foods are deteriorating diets, promoting overeating, and exposing consumers to harmful substances. This culminates in an escalation of chronic diseases; as research suggests.

Popkin contributed to some of the studies referenced in The Lancet.

“We are in poor health, and our diets significantly contribute to this. While we’ve tackled smoking, cholesterol issues, and heart ailments with medication, our food choices are detrimental to our health,” he remarked. “The most reputable and frequently cited medical journals have deemed this a subject worthy of global presentation.”

The Surprising Benefits of Some Ultra-Processed Foods

Ultra-processed foods (UPFs) have been labeled as “poison,” “addictive,” and “junk,” sparking justified concerns due to their links with various health issues, including obesity, type 2 diabetes, anxiety, and depression.

Their rapid rise has transformed the food landscape so drastically that what we consume today would be unrecognizable to even recent generations. From an evolutionary perspective, our bodies certainly aren’t equipped to handle them.

It’s no surprise that UPFs are a primary focus in efforts to tackle diet-related chronic diseases in the UK and US. However, we believe that the prevailing panic surrounding UPFs needs to be replaced with more thoughtful discussions. Not all ultra-processed items, like flavored yogurt or whole grain bread, deserve the same cautionary approach as sweets or sugary cereals. Being ultra-processed doesn’t inherently equate to being unhealthy; our perspective should be informed by previous scientific research.

As people consume more UPFs, their intake of saturated fat, sodium, and sugar tends to rise, while their intake of fiber, protein, and vital micronutrients declines. This trend runs counter to a healthy diet. Kevin’s recent research indicates that UPFs are often overeaten when they are energy-dense (more calories per bite) or particularly palatable (often combining nutrients such as sugars and fats that rarely coexist in nature).

On the other hand, Kevin’s research demonstrates that consuming UPF-rich meals that are energy-dense but less palatable can prevent weight gain. In fact, you could potentially lose weight even without intending to follow such a diet.

These insights hold significant implications, not only for individual choices but also for nutrition policies and regulations. Instead of broadly targeting all UPFs, efforts should concentrate on those that don’t meet healthy food standards. The U.S. Food and Drug Administration (FDA) is already heading in this direction, having recently introduced a definition of “healthy” food. This approach mirrors the UK’s nutritional profiling system, which emphasizes increasing the consumption of ingredients like fruits, vegetables, and whole grains while restricting sugar, sodium, and saturated fat. By honing in on UPFs with high-calorie or palatability-inducing combinations of nutrients, we can better tackle products that significantly contribute to obesity and related health concerns.

Addressing these specific foods requires implementing public health policies akin to those used in reducing tobacco usage, such as marketing limitations, compulsory labeling, and robust taxation. Furthermore, we must promote policies that improve the convenience, affordability, and accessibility of healthy foods, while also encouraging companies to reformulate UPFs to be healthier. For instance, envision a pizza made with a frozen whole-wheat crust topped with vegetables.

Some UPFs already align with FDA standards for healthy foods (such as whole grain bread and yogurt), and these items are today free from such regulations. Many people rely on UPF pasta sauces, hummus, frozen meals, canned beans, and bread, which can easily fit into a healthy diet. Therefore, it is crucial to pinpoint which UPFs pose the greatest risk.

While UPFs are not going away anytime soon, their narrative is still evolving. Let’s move past the fear and toward informed coexistence by recognizing how certain UPFs can be detrimental and taking appropriate action.

6 “Healthy” Foods That Are Actually Ultra-Processed

Many of us include staple foods like pasta and rice in our diets for balance, while avoiding unhealthy options like potato chips and sugary snacks. However, determining the healthiness of processed and packaged foods based on their labels can be challenging.

A recent study found that ultra-processed foods increase the risk of over 30 health problems, highlighting the importance of considering the level of processing and its impact on our health.

It’s essential to understand that all foods can have a place in a healthy diet, but not all are equally nutritious. Rather than relying solely on food labels, it’s crucial to consider how these foods fit into your overall lifestyle and goals, taking into account factors like health, finances, work, and time constraints.

When faced with headlines about certain foods increasing the risk of disease by a certain percentage, it’s important to remember that these numbers represent relative risks in the population, not individual risks. Factors like the amount and frequency of consumption, overall diet, and disease likelihood all play a role in determining actual risk.

Nutrition is not isolated but influenced by evidence, hype, and context when making healthy choices. Here are some common supermarket products that are often misunderstood:

“Premium” Instant Meals

Prepackaged meals marketed as premium options may seem convenient and tasty, but they often contain added preservatives, stabilizers, and high levels of salt. Cooking from scratch at home is typically a more nutritionally sound choice.

When preparing meals at home, there’s more opportunity to add vegetables and whole grains for a balanced diet, something often lacking in ready-made options.

Plant Milk

Plant-based milks marketed as alternatives to dairy products vary in nutritional value, and they can be highly processed. While they can be useful for those who cannot or choose not to consume traditional milk, their long-term health effects are not well-studied compared to whole plant foods.

Meat Substitute

Similarly, meat substitutes may be processed and lack the full benefits of whole plant foods. Replacing meat in the diet can be beneficial for health, but choosing minimally processed plant-based options is key.

Meal Replacement Drinks

While meal replacement drinks can offer complete nutrition and convenience, they lack the bioactive substances found in whole foods. It’s important to incorporate a variety of foods into your diet and seek professional advice if relying heavily on meal replacements.

Breakfast Cereal

Breakfast cereals range in nutritional quality, with some being minimally processed and others high in sugar. Studies suggest that consuming breakfast cereal can improve overall nutrition, but the context of an entire diet is crucial.

Granola/Protein Bars

Bars can be convenient but are often processed and may contain excessive salt, sugar, and additives. While they can offer benefits over unhealthy snacks, they should not replace whole foods in the diet.
