On the flip facet, a food regimen wealthy in purple meat and high-fat dairy meals seems to be hazardous for males with this type of most cancers.

The brand new examine concerned greater than 900 Physicians’ Well being Research members. 5 years after being identified with non-metastatic prostate most cancers, they accomplished prolonged questionnaires about what they ate.
