Ultra-Processed Foods Should Be Illegal: An Empirical Argument for Government Prohibition

Ultra-processed foods (UPFs) have become a dominant feature of modern diets and are increasingly associated with severe public health harms. Research shows, for example, that about 55% of calories consumed in the United States are from UPFs (Williams, Couch, Emmerich, & Ogburn, 2025) [19], and these foods are associated with a significant portion of the roughly one million people who die from food-related conditions in the United States each year (Robinson, 2025) [13]. These foods, which are industrial formulations composed largely of refined substances, additives, preservatives, and synthetic ingredients, have been linked to obesity, cardiovascular disease, diabetes, cancer, depression, and premature mortality (Lane, Gamage, Du, Ashtree, McGuinness, Gauci, et al., 2024) [7]. This paper argues that ultra-processed foods should be made illegal because the harms they impose on society are substantial, measurable, and preventable. Drawing on empirical evidence from large cohort studies, randomized controlled trials, and umbrella reviews, this paper demonstrates that UPFs contribute directly to chronic disease and excessive caloric intake. The paper further argues that the social costs of UPF consumption, which includes increased healthcare spending, reduced productivity, and preventable deaths, justify strong government intervention. Although critics might argue that prohibition would infringe on consumer freedom and create economic disruption, governments have historically prohibited harmful substances when evidence demonstrated overwhelming public danger. By comparing ultra-processed foods to products such as tobacco, lead paint, and trans fats, this paper concludes that banning ultra-processed foods is ethically justified and necessary for protecting public health.
