Colorectal cancer is the third most common cancer and second deadliest cancer in the U.S., causing over 50,000 deaths each year. A new study shows that the typical American diet might be to blame. In a new study published in the journal Gastroenterology, researchers from Brigham and Women’s Hospital in Boston found that diets consisting mainly of red meats, processed meats, sugar, and refined carbs were associated with colorectal tumors containing elevated amounts of pks+ E. coli bacteria. The scientists believe this bacteria increases the cancer-inducing activity of an intestinal compound called colibactin. Plus, these typical Western diets have been shown to cause inflammation in the gut and throughout the body, which are also precursors to colorectal tumors.
