Nearly half of American adults are unaware of the link between eating processed meats and an increased risk of colorectal cancer, according to a novel poll released in March, which is National Colorectal Cancer Awareness Month. The findings, from the Physicians Committee for Responsible Medicine and Morning Consult, highlight a significant gap in public knowledge about preventable cancer risks. This lack of awareness is particularly concerning given the rising incidence of colorectal cancer, now the leading cause of cancer deaths in adults under 50.
The poll, conducted February 9-11, 2026, among 2,202 U.S. Adults, revealed that 48% of respondents did not know that processed meat consumption is associated with a higher risk of developing colorectal cancer. However, awareness appeared to influence behavior: approximately two-thirds of those surveyed indicated they would support warning labels on processed meat products if informed of the cancer risk. This suggests a willingness to make informed choices, but hinges on access to clear and accessible information.
The Rising Tide of Colorectal Cancer in Younger Adults
The increasing rates of colorectal cancer among younger populations are prompting renewed focus on modifiable risk factors, including diet. According to research published in JAMA, colorectal cancer is now the leading cause of cancer deaths in adults under 50. “In light of this alarming trend, it’s concerning that so many people still don’t know about the strong connection between eating processed meat and the risk of developing colorectal cancer,” says Joseph Barrocas, MD, an internal medicine specialist from Huntersville, North Carolina. Dr. Barrocas emphasizes that the poll’s results are encouraging, demonstrating an openness to learning more about these risks.
Processed meats include bacon, sausage, hot dogs, lunch meats, and other products that have been preserved through smoking, curing, salting, or adding chemical preservatives. The World Health Organization’s International Agency for Research on Cancer (IARC) classified processed meat as a Group 1 carcinogen in 2015, meaning there is sufficient evidence to conclude it causes cancer. The IARC report specifically linked processed meat to colorectal cancer.
A Gap in Healthcare Communication
The poll also revealed a significant disconnect between scientific understanding and patient education. Only about one in three adults recall receiving information from a healthcare professional about the link between processed meat and colon cancer. This suggests a need for greater emphasis on dietary counseling within routine medical care.
“More health care practitioners have to be educated about the link between diet and colorectal cancer,” Dr. Barrocas states. “And in addition to recommending screening, discuss with patients the protective benefits of a diet rich in fruits, vegetables, grains, and beans.” Regular colorectal cancer screenings, such as colonoscopies, are crucial for early detection and prevention, but lifestyle factors play a significant role in overall risk.
Diet and Lifestyle: Powerful Tools for Prevention
Research consistently demonstrates that dietary and lifestyle choices can significantly impact colorectal cancer risk. A plant-based diet, rich in fruits, vegetables, whole grains, and legumes, has been associated with a 22% lower risk of developing colorectal cancers compared to an omnivorous diet, according to a study published in JAMA Internal Medicine. The study suggests that phytochemicals found in plant foods may offer protective benefits against cancer.
Beyond diet, maintaining a healthy weight, limiting alcohol consumption, and engaging in regular physical activity are also linked to a reduced risk. Maintaining a healthy weight, limiting alcohol, and staying physically active are all important components of a preventative lifestyle.
The Power of Fiber
Fiber, the indigestible part of plant foods, plays a particularly important role in colorectal health. Research indicates that a high-fiber diet supports intestinal health and helps move food more quickly through the digestive system, reducing exposure to potential carcinogens. One study found that individuals with the highest fiber intake had a 72% lower risk of developing colon polyps, precursors to colorectal cancer, compared to those with the lowest intake.
“Research shows that for every 10 grams of fiber we eat each day, we can lower our colorectal cancer risk by up to 10%,” explains Anna Herby, DHSc, RD, CDE, nutrition education specialist for the Physicians Committee. “Simple ways to get that in include eating a little over a cup of raspberries, 2 tablespoons of chia seeds, or two-thirds cup of black beans.”
The Physicians Committee offers resources to help individuals adopt plant-based eating patterns. Their Food for Life program, developed by doctors and dietitians, provides nutrition and cooking classes online and across the United States. Information about upcoming classes is available on their website.

Looking ahead, the Physicians Committee plans to continue its advocacy for increased public awareness and dietary education. Further research is also underway to explore the specific mechanisms by which plant-based diets protect against colorectal cancer. The organization will be releasing additional data from its ongoing studies in the coming months.
