Diet and lifestyle after prostate cancer diagnosis were linked to differing outcomes
A systematic review found suggestive, inconsistent links between healthier patterns and cancer outcomes. Evidence on deaths from any cause was distinct from evidence on deaths attributed to prostate cancer.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Several studies linked diets emphasizing plant foods and healthier lifestyle patterns after diagnosis with less prostate cancer progression or fewer prostate cancer deaths, although findings did not all agree. Associations with deaths from any cause were also reported. The abstract does not establish that changing these patterns causes better cancer outcomes for an individual.
The abstract provides no pooled effect estimates or follow-up durations. The authors call for stronger studies, longer follow-up and more prostate cancer deaths to assess, underscoring uncertainty about cancer-specific outcomes.
Cause of death matters
Mediterranean and other healthier patterns were associated with fewer deaths from any cause, while a Western pattern was linked to more. Overall mortality is broader than prostate cancer mortality and should be interpreted separately.
Patterns were broader than foods
The review considered dietary indices and combined lifestyle measures after diagnosis. Its conclusions concern overall patterns, including activity, smoking and weight. They do not identify a single food responsible for the reported associations.
