As of 2022, approximately 1.9 million individuals have been diagnosed with colorectal cancer, highlighting a significant health concern worldwide. A recent study has reinforced the existing evidence linking the consumption of red and processed meats to an elevated risk of bowel cancer. Conducted by researchers at the University of Oxford, the study found that consuming an additional 30 grams of red and processed meat per day can increase a person's cancer risk by 8%. This revelation has sparked interest among researchers and experts in the field, as it aligns with current understandings of dietary impacts on gastrointestinal health.
Keren Papier, the lead author of the study and a senior nutritional epidemiologist based at the University of Oxford, commented on the findings in a press release. She emphasized that the study's results are consistent with prior knowledge about the potential risks associated with red and processed meat consumption. The study's insights have potential implications for dietary guidelines and public health recommendations.
Richard Vora, Director of Research and External Affairs at Bowel Cancer UK, commented on the study's outcomes, despite not being involved in the research. He noted the longstanding association between dietary intake and the development of gastrointestinal cancers such as colon cancer.
“I think that we’ve long been associating the intake that humans have with the potential development of [gastrointestinal] cancer, such as colon cancer. So I think it’s interesting [and] I think it’s in line with what we think is a potential problem,” – Vora
Additionally, Vora addressed changing dietary patterns, particularly among younger populations, as a possible factor contributing to rising colon cancer rates.
“I think there’s a growing notion that the reason why there’s an increasing incidence of colon cancer, especially amongst younger people, is because diets have changed,” – Vora
He also highlighted the role of studies like this in potentially guiding future research and informing dietary recommendations for reducing colon cancer risk.
“And all of this is still hypothesized, but studies like this, which could generate more research and more powerful studies, may be able to educate us in telling patients what they should and shouldn’t be eating to lower their risk of colon cancer.” – Vora
The study's findings underscore the importance of understanding nutritional components linked to colorectal cancer risk. For instance, nutrients such as calcium, phosphorus, potassium, and riboflavin are pivotal in reducing this risk. A cup of milk provides approximately 300 mg of calcium, serving as a potential dietary consideration for mitigating cancer risk.
“It is important to understand that the nutrients related to reducing colorectal risk, such as calcium, phosphorus, potassium, and riboflavin are not solely related to dairy,” – Richard
