News — Colorectal cancer remains a leading cause of cancer-related deaths, and has been rising in younger people, but now, new research suggests that dietary choices may play a more significant role in prevention than previously thought.
Recent studies indicate a potential positive link between consuming milk, dairy products, carbohydrates, and fiber, and a reduced risk of developing this devastating disease. Although more research is needed, experts say, this promising news offers a potential avenue for proactive prevention through everyday dietary choices. This as the incidence rate of early-onset colorectal cancer is expected to double by 2030, according to the National Institutes of Health.
While previous dietary guidelines often focused on limiting certain food groups, this emerging research suggests a more nuanced approach. The studies highlight the potential benefits of incorporating specific carbohydrates and fiber-rich foods, along with milk and dairy, into a balanced diet. This shift in understanding underscores the importance of ongoing research and its potential to empower individuals to take control of their colorectal health.
"This new research takes a deeper look at the complex interplay between diet, gut health, and cancer development,” explains Steven Lee-Kong, M.D., chief of Colorectal Surgery at Hackensack Meridian Hackensack University Medical Center. “It reinforces the importance of a balanced and informed approach to nutrition as part of a comprehensive strategy for colorectal cancer prevention."
Here are some key elements this new approach:
- Research increasingly points to the crucial role of the gut microbiome – the community of microorganisms living in our digestive tract – in overall health and disease prevention, including colorectal cancer. Certain foods, like fiber, can selectively nourish beneficial gut bacteria, leading to a healthier gut environment and potentially reducing cancer risk. Conversely, diets high in processed meats and low in fiber can promote the growth of harmful bacteria that may contribute to inflammation and cancer development.
- While fiber has long been associated with digestive health, its role in cancer prevention is becoming clearer. Fiber adds bulk to the stool, speeding up transit time through the colon and reducing the exposure of the colon lining to potential carcinogens. Fermentable fibers are also broken down by gut bacteria into short-chain fatty acids (SCFAs), like butyrate, which have anti-inflammatory and anti-cancer properties.
- The previous emphasis on restricting all carbohydrates is giving way to a more nuanced approach. Not all carbs are created equal. Refined carbohydrates and added sugars can contribute to inflammation and insulin resistance, potentially increasing cancer risk. However, complex carbohydrates found in whole grains, fruits, and vegetables provide essential nutrients and fiber, which are beneficial for gut health and may protect against colorectal cancer.
- Emerging research suggests that dairy products, particularly milk, may have a protective effect against colorectal cancer. This could be due to various factors, including calcium, vitamin D, and potentially other bioactive compounds in dairy. However, more research is needed to fully understand these potential benefits.
“While diet plays a role, regular screening remains the most effective way to detect and treat colorectal cancer early,” says , M.D., FACS, FASCRS, Vice Chairman, Surgery and Chief of the Division of Colon and Rectal Surgery, Hackensack Meridian Jersey Shore University Medical Center. “Most people should get screened for colorectal cancer starting at age 45. The gold standard for screening remains getting a colonoscopy, since any polyps that are discovered can be removed by the physician during the procedure.” Dr. Parker also notes that people who are at high risk for colon cancer should receive coloscopies at earlier ages; they include people with a family history of colon cancer, people with certain genetics (familial adenomatous polyposis (FAP)), and people who smoke and drink alcohol excessively, eat diets high in red and processed meats and low in whole grains, vegetables and fruits and those who are physically inactive.
During the month of March, Colorectal Cancer Awareness Month, we invite you to speak with Dr. Steven Lee-Kong, Dr. Glenn Parker and other Hackensack Meridian Health experts in this field, to discuss this important topic and provide your audience with valuable information that could potentially save lives. They can also emphasize the importance of adhering to recommended screening guidelines.
