Ultra-processed foods have become a regular part of modern life. They are found in supermarkets, convenience stores, school lunches, and restaurant menus.
Many people rely on them because they are quick, affordable, and easy to prepare. Yet a new study suggests that Americans are becoming increasingly concerned about the possible health effects of these foods.
Researchers from Cornell University conducted a nationwide survey to examine how people view ultra-processed foods and whether they support policies designed to reduce their consumption. The findings were published in the American Journal of Public Health and reveal broad concern across the political spectrum.
Ultra-processed foods include products such as soft drinks, packaged desserts, processed meats, chips, and many ready-to-eat meals.
These products often contain a long list of ingredients, including additives, flavor enhancers, sweeteners, and preservatives. Scientists have increasingly linked diets high in ultra-processed foods to obesity, diabetes, heart disease, and other chronic illnesses.
To better understand public opinion, the researchers surveyed 2,000 adults from different backgrounds across the United States. The results showed that many Americans already believe these foods are harmful. More than six in ten respondents said they think ultra-processed foods are addictive and play a major role in causing serious health conditions.
Many participants also expressed concerns about the behavior of food companies. More than 60% believed that some manufacturers intentionally design products to encourage overconsumption. There was also concern that children are particularly vulnerable to advertising and marketing strategies used to promote these products.
The survey found that people viewed the health risks of ultra-processed foods as significant. While respondents generally considered cigarettes to be more dangerous, many ranked ultra-processed foods alongside alcohol in terms of health concerns. Some participants even viewed them as more problematic than fast food or cannabis.
Perhaps the most important finding was the strong agreement among people with different political beliefs. Public health issues often become highly polarized, with disagreements over regulation and personal responsibility. In contrast, attitudes toward ultra-processed foods showed remarkable consistency across party lines.
Researchers believe this may reflect a growing public perception that food choices are influenced not only by individual decisions but also by product design, advertising, and the broader food environment. This shift in thinking may help explain why support for policy action was so widespread.
More than 80% of respondents supported government testing of laboratory-created food chemicals before they can be used in products. Large majorities also supported educational campaigns, restrictions on advertising aimed at children, warning labels, and limits on certain food additives.
Many participants were also open to legal actions that could hold food companies accountable if evidence shows their products contribute to poor health.
Despite these strong opinions, the study revealed an important knowledge gap. Although more than half of respondents had heard the term “ultra-processed food,” only about one-third felt confident explaining it. This suggests that public awareness is growing faster than public understanding.
The researchers compared the current situation to the history of tobacco regulation. Public attitudes toward smoking changed dramatically once evidence accumulated about health harms and industry practices. The authors suggest that a similar shift may now be occurring with ultra-processed foods.
As with any survey, there are limitations. The study measured opinions rather than medical outcomes, and public views can change over time. However, the large sample size and national representation provide valuable insight into how Americans currently think about food and health.
The findings suggest that ultra-processed foods have moved from being a niche nutrition topic into a mainstream public health concern. If these attitudes continue to strengthen, they could influence future policies, food industry practices, and public health campaigns aimed at improving the nation’s diet and reducing chronic disease.
