Cancer protection: New evidence for three dietary defenders

Scientists have long known that gut bacteria convert fiber into beneficial compounds. New research shows precisely how one of these packages DNA in cancer cells, potentially slowing their growth and spread. This insight helps explain why diets rich in vegetables, whole grains, fruits, and nuts have long been associated with lower cancer risk.

The evidence for other foods is also compelling. Research analyzing data from over 542,000 people found that adding just one glass of milk daily — or its calcium equivalent of 300 milligrams — could lower colorectal cancer risk by 17%. Scientists think this might be because calcium binds to bile acids in the gut, though the exact mechanism needs further study.

Coffee, too, shows promise: Four or more cups daily have been linked to lower head and neck cancer risk. However, as Dr. Kanwar Kelley cautions, “Those sensitive to caffeine will likely have difficulty drinking this much coffee to experience the effect.”
