4 in 10 global cancer cases are preventable, landmark study finds

A new landmark analysis from the World Health Organization (WHO) and its subdivision, the International Agency for Research on Cancer (IARC), emphasizes just how many cancer cases globally could be prevented through lifestyle choices.

The virus is carried by fruit bats, or “flying foxes,” that infect a popular delicacy as well as other mammals with whom humans work in the Asia-Pacific region.

In the study, the sudden influx of oats led to beneficial gut microbiome activity that may disrupt cholesterol handling at the cellular level. A parallel six-week study by the same researchers, which replaced one meal a day with oats, did not observe similar cholesterol reductions.
