Bowel cancer, also known as colorectal cancer, is the third deadliest cancer in the United States and is increasingly being diagnosed in younger people. Recent data from the UK reveals that early-onset colorectal cancer is surging among Millennials and Gen Z, rising approximately 3.6% per year in people under 50—a trend seen only in a few countries worldwide.
Experts from healthcare review platform Doctify have identified seven common foods linked to an increased risk of bowel cancer. Consultant gastroenterologist Dr. Angad Dhillon emphasized that diets high in processed and red meats, especially those low in fiber, contribute significantly to the disease’s development. Obesity, sedentary lifestyles, smoking, and heavy alcohol consumption further elevate risk.
“Ultra-processed foods may also disrupt the gut microbiome,” Dr. Dhillon explained, highlighting the modern diet’s role in fueling inflammation that can lead to cancer. Early exposure to processed foods, rising childhood obesity, and increased antibiotic use in childhood may also affect microbiome health and increase risk.
Dr. Reshma Rakshit stresses the importance of adequate fiber intake—30 grams daily as recommended by the NHS—through fruits, vegetables, whole grains, nuts, and seeds. She advises drinking 1.5 to 2 liters of non-caffeinated fluids daily to support digestive health.
Foods to limit include processed meats like bacon, sausages, and ham; red meats; sugary snacks and drinks; excessive sweeteners; alcohol; and caffeine. To counteract risks, experts recommend a plant-based diet rich in whole grains, legumes, fermented foods, and antioxidant-rich items like oily fish and berries. Staying active, maintaining a healthy weight, and managing stress are also crucial in guarding against bowel cancer.
While there is no one-size-fits-all solution, these lifestyle choices, combined with regular medical check-ups, can help reduce the growing burden of colorectal cancer in young people.
