How does yogurt consumption affect colon cancer risk according to Harvard research?

According to Dr. Shuji Ogino's Harvard Medical School research, yogurt consumption is linked to reduced risk of aggressive colon cancer. The comprehensive study, which tracked 130,000 individuals for up to 40 years, found that probiotics, particularly Bifidobacterium in yogurt, enhance gut barrier function, potentially providing protective effects against cancer development. Dr. Ogino specifically recommends unsweetened plain yogurt as the healthiest option, cautioning against sugar-laden varieties that may increase health risks. This groundbreaking research highlights fermented foods' potential role in cancer prevention and opens new avenues for further studies in nutritional approaches to cancer risk reduction.
