Research ties gut bacteria to young-onset colorectal cancer

(NaturalHealth365)  Colorectal cancer rates are climbing among millennials and Generation Z.  Some attribute this trend to the growing consumption of unhealthy processed foods.   In contrast, others highlight sedentary lifestyles as a contributing factor to the rise in colorectal and other cancers.

However, the true underlying cause might be relatively unknown to many: gut bacteria.  Recent research published in eBioMedicine suggests a connection between gut bacteria and the increased incidence of colorectal cancer in young individuals.

Is gut bacteria to blame for the significant increase in colorectal cancer?

The research analyzed the bacteria present in tumors of individuals belonging to Generation Z and millennials with those of older age groups.  The findings revealed that younger individuals exhibited a wider variety of bacteria within their colorectal cancer tumors in comparison to older adults.  Additionally, certain types of bacteria were more prevalent in tumors among younger individuals.

To better understand the reasons behind this phenomenon and pinpoint the cause of the increase in colorectal cancer among young people, the study examined three factors: the location of the tumor, its stage of advancement, and the patient’s weight.

Both age groups examined in the study showed a lower diversity of bacterial species within tumors compared to surrounding tissue.  However, the older age group exhibited even less diversity in bacterial species than the younger cohort.

Consequently, scientists speculate that only a small fraction of gut bacteria can survive within a tumor.  The transient presence of these bacteria in tumor environments is likely due to a lack of oxygen.

The obvious must be said: Correlation does not indicate causation

There are lingering questions about the behavior of bacteria within tumors and why certain species thrive in such environments.  However, the study’s authors firmly believe that the association between specific gut microbes and colorectal cancer is genuine and concerning.  While there’s no conclusive evidence proving these bacteria directly cause the increase in colorectal cancer cases, there appears to be a significant correlation.

Further research is necessary to deepen our understanding of these differences and develop innovative approaches for preventing and treating colorectal cancer in young adults.  Looking ahead a few years, it’s plausible that analyzing patients’ gut microbiota could aid doctors in detecting early signs of cancer in young individuals.

Crafty ways to boost your gut health

Beyond the suggestion of regular screenings for colorectal cancer, which are recommended for individuals aged 45 and older but also encouraged for younger adults, there are various steps you can take to promote gut health and greatly lower your risk of developing colorectal cancer.

Consider incorporating a probiotic and a prebiotic into your daily supplement routine to support a healthy balance of gut bacteria.  While meals high in factory-farm meat and alcohol may be tempting, it’s advisable to limit their consumption as they have been linked to an increased risk of cancer.

Instead, focus on consuming a fiber-rich diet, including foods like organic apples, raisins, prunes, lentils, and dark leafy greens.  Additionally, incorporating fermented foods like sauerkraut into your diet can also benefit gut health.  In addition, you can try some miso soup or raw kombucha – a delicious fermented and carbonated drink, helps regulate gut bacteria, promoting a more balanced microbiota and potentially reducing the likelihood of colorectal cancer.

The key takeaway is that by making dietary adjustments and prioritizing gut health, you can proactively maintain overall well-being and significantly reduce your risk of colorectal cancer.
