Half of US Adults Unaware of Processed Meat-Colorectal Cancer Link | Healio

Nearly half of U.S. Adults are unaware of the link between processed meat consumption and an increased risk of colorectal cancer, according to a recent poll released March 6, 2026. The findings, while concerning, highlight a potential opportunity for improved public health messaging and, perhaps, policy changes like warning labels on these products.

The Persistent Appeal of Processed Meats

From hot dogs at sporting events to bacon with breakfast and deli sandwiches for lunch, processed meats are deeply ingrained in the American diet. But this widespread consumption occurs alongside a significant gap in public understanding regarding the associated health risks. The poll, conducted by the Physicians Committee for Responsible Medicine (PCRM) in collaboration with Morning Consult between February 9-11, surveyed over 2,200 U.S. Adults.

The results revealed that only 55% of respondents correctly identified processed meat as a risk factor for colorectal cancer. A small percentage (5%) incorrectly believed it reduced risk, while 15% stated it had no effect and 25% reported they didn’t know or had no opinion. This lack of awareness is not entirely surprising, according to Anna Herby, DHSc, RD, CDCES, a nutrition education specialist with PCRM. “We certainly wish more people knew about the link,” Herby told Healio. “The fact that half of the population does know shows the health care community is making progress in terms of helping people become aware of the connection, but there is still a lot more work to do.”

What the Evidence Shows

The International Agency for Research on Cancer (IARC) classifies processed meat as a Group 1 carcinogen – the highest risk category – meaning there is sufficient evidence to conclude it causes cancer in humans. This classification places processed meat in the same category as tobacco, asbestos, and certain infections like HPV. The link isn’t about a single exposure, but rather cumulative risk over a lifetime.

The PCRM poll similarly revealed disparities in awareness based on demographics. Older adults (65 years and older) were more likely to be aware of the risk (68%) compared to younger adults (18-34 years, 47%). Awareness also increased with household income (78% for those earning over $100,000 versus 46% for those earning less than $50,000) and educational attainment (70% with a college degree versus 46% without). What we have is particularly concerning given the rising incidence of early-onset colorectal cancer, defined as cases diagnosed before age 50.

Understanding the Rise in Early-Onset Cases

Colorectal cancer is now the leading cause of cancer death among adults under 50 in the United States. While overall incidence has declined since 2013, the increase in younger adults is a significant public health concern. Rebecca L. Siegel, MPH, senior scientific director of surveillance research at the American Cancer Society, notes that modifiable risk factors contribute to more than half of colorectal cancer cases. While smoking, obesity, and lack of physical activity receive considerable attention, the role of diet – specifically red and processed meats – often isn’t emphasized enough.

Siegel emphasizes that the evidence linking processed meat to cancer is “incontrovertible.” She also cautions against the misconception that purchasing premium brands of processed meat reduces risk. “It doesn’t matter how much it costs,” she said. “It’s still processed.”

Support for Warning Labels and the Role of Clinicians

The poll offered a glimmer of hope: 64% of respondents indicated they would support warning labels on processed meat products specifying the cancer risk. This suggests a willingness among the public to be informed about potential health hazards. However, the poll also highlighted a gap in communication between healthcare professionals and their patients. While 62% of respondents reported receiving information about nutrition’s effect on colorectal cancer risk, only 33% received that information from a doctor or other healthcare provider. Social media, friends, family, and news outlets were more frequently cited as sources.

Shikha Jain, MD, FACP, associate professor of medicine at the University of Illinois Cancer Center, believes clinicians have a responsibility to address this gap. “We need to be more direct and more consistent in how we communicate the risks associated with diets high in processed meats,” Jain said. “As clinicians, we have a responsibility not just to treat disease but to prevent it.”

What So for Your Diet

The key takeaway isn’t necessarily about eliminating processed meat entirely for everyone, but about informed decision-making. Reducing consumption, even incrementally, can lower risk. Herby suggests a step-by-step approach for those who find it tricky to eliminate processed meats altogether. Focusing on incorporating more fruits, vegetables, beans, whole grains, and high-fiber foods into the diet is also crucial.

Looking Ahead: Education and Policy

PCRM is actively working to bridge the knowledge gap among healthcare professionals through continuing medical education courses, an annual nutrition and medicine conference, and freely available resources like the Nutrition Guide for Clinicians and fact sheets. The organization hopes that increased awareness among clinicians will translate into more informed conversations with patients.

The potential for policy changes, such as warning labels, also remains on the horizon. While implementing such measures may face challenges, the poll results suggest significant public support. The process of translating scientific evidence into effective public health policy often takes time, but the growing awareness of the risks associated with processed meat consumption is a positive step in the right direction.
