In recent years, the number of children, teens, and young adults with colorectal cancer has increased. To determine whether the gut microbiota and diet have an effect on the development of colorectal cancer, researchers recently investigated various diets and bacteria. To determine whether there were any effects on the gut, the researchers paired three distinct bacterial strains with three different diets. They discovered that a certain strain of Escherichia coli in conjunction with a low-carb, low-fiber diet can cause an increase in colon polyps, which can result in the development of colorectal cancer.

Although low-carb diets, like the ketogenic diet, have become more popular recently, many experts question whether a more restrictive diet could have detrimental effects on one’s health. In a recent study, researchers from the University of Toronto in Canada investigated the potential effects of low-carb diets on bacteria associated with colorectal cancer. In their study, the researchers employed mice and examined various bacterial strains as well as low-carb, typical, and Westernized diets.

They concentrated on whether these diets have an effect on specific bacteria and how that could lead to the development of colorectal cancer. The findings of their study demonstrated that low-carb diets have a detrimental effect on a particular strain of Escherichia coli. The researchers discovered that it accelerated the growth of polyps. Certain polyps can progress to colorectal cancer.

How might certain bacteria lead to cancer?
One of the most common types of cancer diagnosed in the US is colorectal cancer, which affects the colon and rectum. One out of every 26 women and one out of every 24 men will develop this cancer. According to recent data, the number of colorectal cancer cases among adults aged 30 to 34 increased by 71% between 1999 and 2020, while the number among adults aged 35 to 39 increased by 58% during the same period. The 5-year survival rate for colorectal cancer is 64.4%, according to the Centers for Disease Control and Prevention (CDC)Trusted Source.

Although prevention of colorectal cancer cannot be guaranteed, there are steps people can take to reduce their risk (Trusted Source). Among these are quitting smoking, consuming less alcohol, eating a diet rich in fruits, vegetables, and whole grains, and avoiding processed foods and red meat.

The new study sought to ascertain whether there was a relationship between particular diet types and particular types of bacteria, as researchers suspect that dietary choices may be linked to the development of colorectal cancer. Three bacteria were the focus of their investigation: Helicobacter hepaticus, E. coli, and Bacteroides fragilis.

They colonized the mice using E. Coli. According to the study’s authors, these microbes either directly damage intestinal epithelial cells’ DNA by producing genotoxins or indirectly by inducing inflammatory mediators that damage DNA. The mice used in the study were fed Western-style diets, which were heavy in fat and sugar, regular chow diets, and diets low in carbs and fiber.

E. coli and low-carb diets increase cancer risk
Following nine weeks of feeding the mice their particular diets, the researchers monitored the mice for the development of polyps and remeasured them at sixteen weeks. Only the combination of the low-carb diet and E was tested among the bacteria and diets. Coli may raise the risk of colorectal cancer, according to research. This is noteworthy because, as stated by the authors of the study, E. Coli is found in 60% of cases of colorectal cancer.

This combination increased the number of tumors and polyps in the mice, which can raise the risk of colorectal cancer. These mice also displayed other indicators that increase the risk of colorectal cancer, including DNA damage. The colon’s protective mucous layer against bacteria was weakened by the low-carb diet. In mice that have E. Colibactin was able to reach colon cells because of this. One genotix that harms DNA is colibactin, according to a reliable source.

Additionally, these mice had cell senescence, which can lead to the development of cancer. The mice on low-carb, low-fiber diets with E had reduced levels of gut health regulation, the researchers discovered. coli, which fuels inflammation. In general, mice fed a low-carb diet paired with E. Coli’s gut microbiome was so disturbed and damaged that scientists discovered it to be a setting that encourages colorectal cancer.

Despite these alarming findings, the researchers discovered that feeding these mice fiber decreased the development of tumors and assisted in regulating inflammation. By figuring out whether particular fiber types are more protective and researching their effects on people, the researchers hope to carry on this line of inquiry.

What dietary changes may help lower cancer risk?
According to the article’s highlighted mouse study, there may be a substantial connection between low-carb diets and colibactin-producing E. She informed us about colorectal cancer and E. Coli. A low-carb diet combined with an E. strain was found to be beneficial by the researchers. Mice with colibactin-producing E. Coli developed colorectal cancer. Cusick described how the low-carb, low-fiber diet and E. coli create an environment in the gut. Coli resulted in a thinner mucous barrier, more polyps, which are cancer precursors, and increased gut inflammation.

Although she described the results as fascinating and captivating, she pointed out that more study is required before they can be used on people. Cusick listed a few forms of fiber that might support the colon’s mucus barrier because the study emphasized how important it is.

Vora was also not involved in the study. “I believe this can be considered hypothesis-generating,” Vora said of the research. The incidence of colorectal cancer may be explained by a real connection. Although Vora agreed that more research is needed on this subject, he also noted that the gut biome is a popular area of study due to its connection to colon cancer and that many new research topics will emerge in this area.
