The Georgia-based heart surgeon, drawing on more than 25 years' experience, said research links every 10% rise in consumption to a 10% increase in mortality risk.
In a YouTube video, London said such industrially made foods can disrupt glucose metabolism, raise triglycerides, increase inflammation and alter the gut microbiome.
The report also cites NHS doctor Chris van Tulleken and British Heart Foundation dietitian Victoria Taylor, who advocate reducing ultra-processed foods and favouring a Mediterranean-style diet.

The Hidden Dangers of Ultra-Processed Foods: Mechanisms, Mortality, and Practical Solutions for 2026
Overview
Veteran surgeon Dr. Jeremy London warns that processed foods, sugary drinks, alcohol, and excess saturated fats shorten lifespan. Supporting this, a 2026 study found that high consumption of ultra-processed foods, which contain industrial additives, disrupts the gut microbiome and causes inflammation. This inflammation raises the risk of chronic diseases like heart disease, type 2 diabetes, and certain cancers, including a 40% higher breast cancer mortality risk in Black women. Poor nutrient profiles in these foods also drive obesity and metabolic problems. Childhood consumption harms nutrient intake and gut development, increasing early-onset colorectal cancer risk. In response, the FDA began defining ultra-processed foods federally in 2025 to guide future policies.
