What did the long-term study about yogurt consumption reveal about colorectal cancer risk?

The study, conducted over decades with more than 130,000 participants from the Nurses Health Study and Health Professionals Follow-up Study, found that regular consumption of unsweetened yogurt (two or more servings weekly) may reduce the risk of aggressive colorectal cancer. This protective effect is likely due to beneficial bacteria like Bifidobacterium present in yogurt that improve gut health. The research represents significant long-term dedication from participants and investigators, highlighting the importance of dietary choices in cancer prevention.
