Processed Foods Tied to Surging Colon Polyps in Young Women
15 Nov
Summary
- 45% higher risk of early-onset colorectal polyps for those with highest ultra-processed food intake
- Processed meats like hot dogs, sausages, and deli meat classified as carcinogenic by WHO
- Nearly 1 in 4 heart disease and stroke deaths linked to ultra-processed food consumption
According to a study published in JAMA Oncology last year, the consumption of ultra-processed foods significantly impacts young women's risk of developing colon polyps, a precursor to colorectal cancer. Researchers followed over 29,000 participants under 50 for 24 years, finding that those with the highest intake of ultra-processed foods had a 45% higher chance of developing early-onset colorectal polyps.
The study's findings are particularly concerning given the alarming rise in colorectal cancer cases among younger patients in recent years. Public health experts have long warned about the dangers of ultra-processed foods, which are high in additives, preservatives, and unhealthy fats and sugars. A separate study published in February 2025 suggests that nearly one in four heart disease and stroke deaths are linked to consuming these highly processed products, which make up over 43% of the average Canadian's daily caloric intake.
Processed meats like hot dogs, sausages, and deli meat have been identified as a major culprit, with the World Health Organization classifying them as carcinogenic in 2015. Experts recommend limiting or avoiding these items, as well as other ultra-processed foods like sweetened cereals, frozen meals, and soft drinks, to reduce the risk of serious health complications.
