Colon Cancer: 7 Ultra-processed Foods You Should Avoid To Reduce The Risk
Introduction Colon cancer is rising rapidly in India, especially among younger adults. Lifestyle choices—particularly the increasing consumption of ultra-processed foods—are strongly linked to this rise. Ultra-processed foods contain preservatives, additives, refined sugar, artificial flavours, and unhealthy fats that damage the gut and increase inflammation, contributing to colon cancer risk. This simple, patient-friendly blog explains which foods to avoid, why they are harmful, and healthier alternatives. Colon Cancer and Ultra-Processed Foods: An Overview Colon cancer begins in the large intestine. While genetics matter, most cases today are linked to diet and lifestyle habits. Ultra-processed foods reduce fibre, harm gut bacteria, and trigger long-term inflammation—major cancer risk factors. What Are Ultra-Processed Foods? Ultra-processed foods (UPFs) include: Preservatives Artificial colours Flavour enhancers Artificial sweeteners Stabilizers Hydrogenated oils Excess salt, sugar, and unhealthy fats These foods lack fibre, nutrients, and natural ingredients, making them harmful to digestive health. 7 Ultra-Processed Foods You Should Avoid to Reduce Colon Cancer Risk 1.
