Yogurt with Live Bacteria May Reduce Risk of Certain Colorectal Cancers

Yogurt containing live bacteria is believed to help protect against various diseases, including some types of cancer. While the exact mechanism remains unclear, experts suggest its benefits may stem from its impact on the gut microbiome.

A recent study published in Gut Microbes and led by researchers from Mass General Brigham found that consuming yogurt with live bacteria regularly may lower the risk of a specific type of colorectal cancer. The study revealed that individuals who consumed at least two servings of live yogurt per week had a 20% reduced likelihood of developing Bifidobacterium-positive bowel tumors.

Colorectal cancer is the third most prevalent cancer globally, accounting for over 10% of all cancer cases, according to the World Health Organization (WHO). Several lifestyle factors, including sedentary behavior, smoking, obesity, excessive alcohol intake, and a diet high in processed meats but low in fruits and vegetables, can increase the risk of developing the disease.

Maintaining a balanced, high-fiber diet rich in fresh fruits, vegetables, whole grains, calcium, and dairy products is associated with a lower risk of colorectal cancer. This study further suggests that incorporating live yogurt into one’s diet may contribute to reducing the risk of certain colorectal tumors by supporting a healthy gut microbiome.
