The long-held belief that whole foods are inherently healthy while processed foods are categorically unhealthy is undergoing scrutiny. This perspective, which simplifies nutrition advice to a straightforward mantra—fresh fruits and vegetables are good, whereas packaged foods are bad—has been prevalent for years. However, emerging research suggests the relationship between food processing and health is far more complex than it appears.
Scientists are beginning to reveal that not all ultra-processed foods impart the same effects on our bodies. While certain ultra-processed items are tied to health risks, others may positively contribute to a balanced diet. This re-evaluation is prompting health experts to reassess their approach to informing the public about these foods.
One Category Obscures the Differences
The classification of “ultra-processed food” arises from a system known as NOVA, which categorizes foods that incorporate industrial ingredients and additives not typically found in home cooking. Unfortunately, this broad classification encompasses a vast array of products, including soda, hot dogs, packaged cookies, whole grain bread, breakfast cereals, protein bars, and plant-based burgers.
This categorization can be misleading, as these foods are vastly different in terms of nutritional value and health impact.
Processed Foods Are Not All the Same
Researchers are now focusing on specific subsets of ultra-processed foods rather than lumping them together. This detailed examination has uncovered significant patterns. Studies indicate that sugary beverages and processed meats such as bacon and hot dogs are associated with an increased risk of heart disease and type 2 diabetes.
Conversely, some ultra-processed items, like whole grain breads and certain cereals, have been linked to reduced health risks. These findings imply that it is not merely the processing itself that defines whether a food is beneficial or detrimental.
Plant-Based Foods Perform Better
A consistent trend in research shows that plant-based ultra-processed foods generally exhibit healthier profiles compared to their animal-based counterparts. Whole grain bread, fortified cereals, and select plant-based meat alternatives often deliver better health outcomes in various studies, while sugary drinks emerge as a major concern.
“Many individuals have been advised to steer clear of processed foods, but scientific insights advocate for a more nuanced understanding,” stated Noah Praamsma, a registered dietitian at the Physicians Committee for Responsible Medicine. “Processed meats like bacon and hot dogs should certainly be avoided, but numerous plant-based options within the ultra-processed category, such as certain breads and cereals, can be quite healthful.”
New Guidelines Proposed
A recent report by Healthy Eating Research suggests that nutritional policies should better align with scientific evidence. The report advocates for differentiated treatment of ultra-processed foods rather than equating them all with unhealthy choices like sugary sodas and processed meats.
Foods rich in beneficial nutrients and lower in sugar, sodium, and saturated fats could be categorized more favorably. This initiative aims to draw a distinct line between healthier packaged foods and those that are significantly associated with health issues.
Policies Informed by Science
The U.S. government is currently working on an official definition for ultra-processed foods, which could influence regulations surrounding school lunches, food labeling, taxation, and advertising methods. A sweeping definition might unintentionally group healthy options like cereals and plant-based burgers alongside sugary drinks and processed meats.
“We need policies grounded in science—void of ideology—that are comprehensive enough to encourage nutritious food choices while discouraging unhealthy options,” Praamsma emphasized.
Changing the Conversation
Major health organizations are also evolving their dialogue regarding ultra-processed foods. In 2025, the American Heart Association acknowledged that not all ultra-processed foods are detrimental and some can be integrated into a well-rounded diet. This perspective marks a significant shift from previous attitudes.
Nutrition guidelines often gain traction because they are easy to remember, such as the directive to “avoid processed foods.” However, simplistic advice often fails to reflect the complexities of science. A slice of whole grain bread and a hot dog may both be labeled as ultra-processed, yet their effects on health can differ dramatically. Equating the two may confuse consumers and dilute the effectiveness of nutritional guidance.
A More Careful Approach
Researchers are now adopting a comprehensive approach that goes beyond basic food processing classifications. They are exploring the nutrients present in foods and how these affect long-term health outcomes. While this methodology may not easily fit into a catchy slogan, it is believed to contribute to more effective nutritional advice in the future.
The evolving research on ultra-processed foods indicates that the narrative surrounding them is not as straightforward as “processed equals bad.” Some processed options can certainly have a role in a nutritious diet, whereas others remain serious concerns.
