New link between Western diet and cancer discovered

0

A new study found that the so-called Western diet, high in sugar, refined grains, and processed meats, increases the risk of colorectal tumors. Scientists from Birgham and Women's Hospital in the USA found that a similar connection is explained by the influence of the intestinal microbiota.

American researchers, in the course of observations of more than 130,000 people from the United States, established a connection between the Western diet and colorectal cancer . This is not the first study that shows that a diet with a large amount of processed meat, flour products and carbohydrates increases the risk of intestinal tumors.

However, for the first time, scientists have demonstrated the mechanism of the influence of a harmful diet on the appearance of malignant neoplasms. They analyzed the diet as well as the DNA of E. coli strains in more than 1,000 colorectal tumors.

The scientists looked for bacterial strains that carry a separate genetic island called polyketide synthase, which codes for an enzyme that causes mutations in human cells.< /p>

A Western diet was associated with these tumors containing high amounts of this island, as well as E. coli, but not with other malignancies.

The results support the hypothesis that a Western diet diet increases the risk of developing colorectal cancer at the expense of intestinal microbiota.

The first study was conducted that linked this eating style with specific pathogenic bacteria. And now it remains to be seen exactly what component of diet or lifestyle is associated with colorectal cancer that contains this type of bacteria.
