What other types of food might offer the same benefit as yogurt in preventing colorectal cancer?

Dr. Shuji Ogino hypothesizes that other fermented foods may provide similar benefits to yogurt in preventing aggressive colorectal cancer. This aligns with their research hypothesis about the protective effects of fermented foods containing beneficial bacteria like Bifidobacterium found in plain yogurt. However, Dr. Ogino emphasizes that more studies are needed to conclusively determine the effects of various fermented foods. While their comprehensive 30-year study with 130,000 participants showed strong evidence for yogurt's benefits, additional research is required to confirm whether other fermented foods offer comparable protection against colorectal cancer.
