Experts warn ultra-processed foods leading to increase in bowel cancer

The video, featuring Oxford based colorectal expert Professor Sir Neil Mortensen and Dr Chris van Tulleken, chair of colorectal charity Occtopus, discusses the potential link between the increase in bowel cancer and the growing consumption of ultra-processed foods (UPF).
The video explores the worrying trend of increasing bowel cancer diagnoses in individuals under 50 and connects this to the modern diet, particularly the surge in UPF consumption.
The video discusses the science behind UPF, products that are heavily refined and often contain additives, preservatives, and artificial flavourings.
Professor Mortensen and Dr van Tulleken suggest that long-term exposure to these food products may increase inflammation, disrupt the gut microbiome, and contribute to the development of cancerous cells in the colon and rectum.
Professor Sir Neil Mortensen said: “We are seeing a significant rise in younger people diagnosed with this condition, and it’s clear that our modern diet plays a key role in this.
“Ultra-processed foods, which are high in unhealthy fats, sugars, and additives, are probably having a profound effect on gut health and overall well-being.”
Dr Chris van Tulleken said: “The rise of ultra-processed foods is not just a trend but a public health crisis in the making.”
The video is part of Occtopus’s ongoing effort to raise awareness about the importance of diet in preventing bowel cancer.
