Dr. James Carmody and colleagues at the University of Massachusetts Medical School in Worcester randomized subjects and their partners to attend 11 dietary and cooking classes emphasizing plant-based foods and fish, or to a control group. Dietary compliance, quality of life and PSA levels at baseline, after the 11-week intervention and again 3 months after intervention were assessed.

The intervention group consumed significantly less saturated fat, more vegetable protein and less animal protein, including dairy products, than controls. They also reported indicators of increased quality of life compared with controls.

“Although no significant change was found in the rate of PSA increase between the two groups, the mean PSA doubling time for the intervention group was substantially longer at the 3-month follow-up visit than that of the controls,” Dr. Carmody and colleagues report.

“Future trials should examine the effect of the prostate-healthy diet with a larger sample of men followed for a longer period,” they conclude.
