What did Dr. Shuji Ogino's decades-long health study reveal about yogurt and colon cancer?

Dr. Ogino's research, spanning decades and involving over 130,000 participants from the Nurses' Health Study and Health Professionals Follow-up Study, found that yogurt consumption can significantly reduce the risk of aggressive colon cancer. This benefit is primarily attributed to yogurt's gut-friendly bacteria, particularly Bifidobacterium, which enhances gut barrier function. The study emphasizes consuming unsweetened plain yogurt rather than sugary varieties for optimal health benefits. These findings suggest potential broader implications for cancer prevention through dietary choices, particularly fermented foods.
