A landmark study published in The Lancet reveals that ultra-processed foods (UPF) are linked to harm in every major organ system, signaling a global health crisis fueled by corporate profit. The research, conducted by 43 leading experts, exposes the aggressive tactics of food corporations in driving UPF consumption while undermining scientific debate and regulatory efforts.
The Scale of the Problem
UPF now comprises over half the average diet in the US and UK, with some populations – particularly those in disadvantaged areas – consuming up to 80% UPF. These foods, including ready meals, sugary drinks, and packaged snacks, are designed for extreme palatability and high caloric density, while being nutritionally poor. This shift away from fresh foods is not accidental; it’s a deliberate strategy by corporations to maximize profits.
“The first paper in this Lancet series indicates that ultra-processed foods harm every major organ system in the human body. The evidence strongly suggests that humans are not biologically adapted to consume them.” – Prof. Carlos Monteiro, University of São Paulo.
The Science Behind the Risk
A systematic review of 104 long-term studies found that 92 reported increased risks of chronic diseases and premature death associated with high UPF diets. This includes obesity, type 2 diabetes, heart disease, and even mental health conditions like depression. UPF consumption drives overeating due to its hyper-palatable nature, delivers poor nutrition, and exposes consumers to harmful chemical additives.
The Nova food classification system – ranging from unprocessed to ultra-processed – highlights the industrial nature of these products. UPF are manufactured with artificial flavors, emulsifiers, and colorings, deliberately displacing traditional foods and maximizing corporate gains.
Corporate Interference and Policy Failures
The study points to the aggressive lobbying and political activities of food corporations as a major barrier to effective public health policy. Companies use front groups and research partnerships to counter opposition and block regulation, prioritizing profit over public well-being. The global response to UPF remains weak, lagging decades behind the progress made in tobacco control.
Proposed Solutions
The Lancet series proposes urgent action, including:
- Mandatory front-of-package labeling identifying UPF ingredients.
- Stricter marketing restrictions, especially targeting children.
- Banning UPF in sensitive settings like schools and hospitals.
- Limiting shelf space for UPF in supermarkets.
Brazil’s national school food program – eliminating most UPF and aiming for 90% fresh/minimally processed foods by 2026 – serves as a successful model.
The evidence is clear: unregulated consumption of ultra-processed foods represents a systemic threat to human health. Addressing this crisis requires immediate, coordinated action to curb corporate influence and prioritize public well-being over industry profits.
