What Are Ultra-Processed Foods—and Why Should You Care?

Return to The Wellness Wednesday Menu
In recent years, the term “ultra-processed food” has been showing up more often in headlines, documentaries, and even doctor’s offices. But what exactly does it mean—and why should you care?
Let’s be honest: most of us eat ultra-processed foods every day. That granola bar you grab between meetings, the frozen pizza on Friday night, or the soda you sip during lunch—these are all likely ultra-processed. While convenient and tasty, growing research suggests that these foods might be doing more harm than good to our health.
This Wellness Wednesday, we unpack what ultra-processed foods are, why they’re so widespread, and what you can do to make healthier choices.

What Are Ultra-Processed Foods?
Ultra-processed foods (UPFs) are industrial formulations made mostly or entirely from substances extracted from foods (like oils, fats, sugar, starch, and protein isolates) or synthesized in laboratories (like artificial flavorings, colorings, and emulsifiers). They’re designed to be hyper-palatable, shelf-stable, and convenient—but at a cost.
According to the NOVA food classification system, which is widely used by nutrition researchers, there are four categories of food processing:
- Unprocessed or minimally processed foods – Think fresh fruits, vegetables, whole grains, and meats.
- Processed culinary ingredients – These include oils, butter, sugar, and salt.
- Processed foods – Such as canned vegetables, cheeses, and freshly baked bread.
- Ultra-processed foods – These are the heavily modified, ready-to-eat products like sugary cereals, packaged snacks, sodas, instant noodles, and fast food.
A key trait of UPFs is that they usually contain little to no whole food ingredients. They’re engineered to be low-effort, appealing, and addictive—often high in calories, salt, sugar, and unhealthy fats, and low in fiber and essential nutrients.
Why Are Ultra-Processed Foods Everywhere?
There’s a reason UPFs make up more than 60% of the American diet (Harvard T.H. Chan School of Public Health). They’re cheap to produce, easy to transport, and incredibly convenient. For food manufacturers, they also provide high profit margins, long shelf lives, and consistent flavor.
For consumers, ultra-processed foods are accessible and often marketed as healthier alternatives through claims like “low-fat,” “high-protein,” or “gluten-free.” They save time in the kitchen, reduce the need for fresh ingredients, and cater to busy modern lifestyles. But despite the convenience, there’s a growing body of research indicating they come with significant health risks.
Health Risks of Ultra-Processed Foods
Here’s where things get serious. A growing number of studies link ultra-processed food consumption with negative health outcomes. The concern isn’t just about the calories—they’re associated with an increased risk of chronic disease, even when controlling for total calorie intake and macronutrient balance.
1. Weight Gain and Obesity
A randomized controlled trial by the National Institutes of Health found that people eating a diet high in ultra-processed foods consumed about 500 more calories per day and gained significantly more weight compared to when they ate a minimally processed diet—despite similar macronutrient profiles.
UPFs are engineered to be overconsumed, with soft textures, intense flavors, and low fiber that allows us to eat more quickly and mindlessly.
2. Increased Risk of Heart Disease and Diabetes
A study published in the journal BMJ linked high consumption of UPFs to a significantly increased risk of cardiovascular disease. Another large-scale study found that each additional 10% of dietary intake from ultra-processed foods was associated with a 15% higher risk of developing type 2 diabetes.
UPFs often contain trans fats, excessive sodium, and added sugars—all known contributors to high blood pressure, insulin resistance, and inflammation.
3. Mental Health Concerns
Emerging research is starting to connect ultra-processed food consumption with poor mental health outcomes. A 2022 study found that higher UPF intake was associated with increased odds of depression, particularly among women. Though the exact mechanisms aren’t fully understood, inflammation and gut microbiota disruption may play a role.
4. Cancer Risk
A French study from the NutriNet-Santé cohort found that a 10% increase in the proportion of ultra-processed foods in the diet was associated with a significantly higher risk of cancer, particularly breast cancer. Again, this doesn’t mean eating a snack cake will give you cancer—but consistent, high consumption over time appears to contribute to cumulative risk.
Why Should You Care?
If the health risks aren’t enough to convince you, there are other reasons to pay attention to how much ultra-processed food you’re consuming.
1. It Can Displace Whole Foods
UPFs don’t just add “bad” ingredients—they often crowd out healthier foods. People eating high-UPF diets usually consume fewer fruits, vegetables, whole grains, and fiber-rich foods. These nutrient-dense options are critical for disease prevention, immune function, and longevity.
2. They’re Tied to Food Addiction Patterns
Ultra-processed foods are intentionally crafted to light up reward pathways in the brain, similar to addictive substances. The term “hyper-palatable” refers to the ideal combo of sugar, salt, and fat that makes foods difficult to resist. Some researchers argue that certain UPFs can promote addictive-like eating behaviors, making moderation extremely difficult.
3. Environmental Impact
UPFs often rely on monoculture crops like corn, wheat, and soy, which are heavily subsidized and produced with high environmental costs. In addition, they come wrapped in layers of plastic, adding to pollution and landfill waste. Shifting toward whole, minimally processed foods often supports more sustainable and local agriculture.
How to Cut Back on Ultra-Processed Foods
Here’s the good news: You don’t have to swear off convenience forever. The key is becoming more aware of what you’re eating and aiming to prioritize whole or minimally processed foods when possible. Here are a few tips:
- Read ingredient lists: If a product has a long list of unrecognizable ingredients or multiple types of added sugar (look for words like high-fructose corn syrup, maltodextrin, dextrose), it’s likely ultra-processed.
- Cook more at home: Meals you make yourself give you full control over ingredients and portion sizes. Even simple dishes like stir-fry, soups, or grain bowls can be healthier and tastier than packaged alternatives.
- Swap smartly: Choose whole-grain bread instead of white, plain yogurt instead of sweetened, or popcorn instead of chips.
- Limit sugary drinks: Sodas, energy drinks, and even flavored coffees are major contributors of UPFs in the diet.
- Shop the perimeter of the grocery store: That’s usually where you’ll find fresh produce, meats, dairy, and other less-processed items.
A Balanced Perspective
Let’s be real: completely avoiding ultra-processed foods may not be realistic for most people. And that’s okay. The goal isn’t perfection—it’s awareness and balance. Enjoying the occasional frozen pizza or packaged snack isn’t going to wreck your health. But being intentional about what’s on your plate most of the time can make a big difference in how you feel, both short and long term.
Final Thoughts
Ultra-processed foods are a huge part of the modern food landscape. They’re convenient, cheap, and designed to be delicious—but they also come with well-documented health risks. As research continues to show links between these foods and chronic diseases, it’s worth paying closer attention to how often we rely on them.
By choosing more whole, minimally processed options and building a more balanced plate, you’re not just avoiding potential downsides—you’re actively supporting your health, energy, and longevity.
So next time you’re in the grocery store or ordering takeout, take a moment to ask: Is this something my great-grandparents would recognize as food? If the answer is no, it might be time to consider a healthier swap.
