Ultra-Processed Foods Need Tobacco-Style Warnings, Says Scientist


Ultra-processed foods (UPFs) are increasingly dominating diets worldwide, replacing healthier alternatives and posing significant health risks. Prof Carlos Monteiro, a renowned nutritional scientist from the University of São Paulo, has called for tobacco-style warnings on UPFs to alert the public to their dangers. This article explores Monteiro’s findings and the growing concerns surrounding UPFs.

What are Ultra-Processed Foods?

Ultra-processed foods are industrial formulations made entirely or mostly from substances extracted from foods, derived from food constituents, or synthesized in laboratories. These include:

  • Cereals
  • Protein bars
  • Fizzy drinks
  • Ready meals
  • Fast food

Why Are UPFs Harmful?

The world’s largest review found UPFs are directly linked to 32 harmful health effects, including:

  • Higher risk of heart disease
  • Cancer
  • Type 2 diabetes
  • Adverse mental health
  • Early death

Monteiro and his colleagues developed the “Nova” food classification system to assess the nutritional content and processing levels of foods. UPFs are classified as the most processed and least healthy.

Rising Consumption of UPFs

In the UK and US, more than half of the average diet consists of UPFs. For some, especially those who are younger, poorer, or from disadvantaged areas, UPFs can make up as much as 80% of their diet.

Health Warnings and Recommendations

Monteiro suggests public health campaigns similar to those against tobacco to curb the dangers of UPFs. His recommendations include:

  • Banning or heavily restricting advertisements for UPFs
  • Introducing front-of-pack warnings
  • Prohibiting sales of UPFs in schools and health facilities
  • Heavy taxation on UPFs to subsidize fresh foods

Comparing UPFs to Tobacco

Monteiro draws parallels between UPF and tobacco companies. Both industries:

  • Cause serious illnesses and premature mortality
  • Are produced by transnational corporations
  • Invest profits in aggressive marketing and lobbying against regulation
  • Create products that are pathogenic by design


Dr. Hilda Mulrooney, a reader in nutrition and health at London Metropolitan University, argues that comparing UPFs to tobacco is too simplistic. She points out that while there is no safe cigarette, foods containing fat, sugar, and salt are essential in certain quantities for their structural, shelf-life, and taste properties.

The Need for Comprehensive Solutions

Addressing the health risks posed by UPFs requires a multifaceted approach, including:

  • Improved public awareness and education
  • Stricter regulations on marketing and sales
  • Research into healthier food alternatives
  • Support for healthier eating habits

Key Takeaways

  • Ultra-processed foods are linked to numerous health risks.
  • Public health campaigns and stricter regulations are needed.
  • Comparing UPFs to tobacco highlights the severity of their impact.
  • Comprehensive solutions are necessary for meaningful change.
