Drinking an eight ounce glass of pomegranate juice daily increased by nearly four times the period during which PSA levels in men treated for prostate cancer remained stable, a three-year UCLA study has found.

The study involved 50 men who had undergone surgery or radiation but who, post treatment, had experienced increases in their prostate-specific antigen or PSA, indicating the continued presence of cancer.
The researchers measured doubling time, the time it took for the PSA level to double.
Of the 50 men enrolled, more than 80 percent experienced improvement in doubling times.
