Science Review Finds 5 UPF Trials Link Harms to Ingredients, Not Processing

2 articles · Updated · Financial Times · Jun 4

Five randomized trials reviewed in Science found no clear evidence that ultra-processing itself uniquely harms health, with observed risks harder to separate from what the foods contain.
High energy density, saturated fat and salt were cited as more likely drivers of harm, while softer textures and faster eating may also help explain overconsumption.
Faidon Magkos said the UPF label can mislead by grouping nutritionally poor products with fortified wholegrain breads, probiotic yoghurts and plant-based milks that may be beneficial.
The review sharpens a broader dispute over whether Nova-style UPF categories should guide diets, even as observational studies still show strong links between high UPF intake, obesity and other adverse outcomes.

Ultra-Processed Foods in 2025: Health Harms, Scientific Debate, and Regulatory Action

Overview

The 2025 Lancet review marked a turning point in the global response to ultra-processed foods (UPFs), highlighting a sharp rise in their consumption and linking this trend to the actions of profit-driven corporations. The review revealed that these companies use aggressive tactics to boost UPF intake, shape scientific debate, and block effective regulation. It found strong connections between high UPF consumption and chronic diseases, drawing parallels to past tobacco control efforts. The review called for urgent, coordinated policy action to address this growing public health crisis, emphasizing the need for systemic solutions rather than relying on individual responsibility.
