Among patients with prostate cancer, greater consumption of plant-based foods is associated with higher scores in quality-of-life domains, according to a study published online Feb. 13 in Cancer.
Stacy Loeb, M.D., Ph.D., from New York University and Manhattan Veterans Affairs in New York City, and colleagues examined the relationship between plant-based diet indices after prostate cancer diagnosis and quality of life in a prospective cohort study involving 3,505 participants in the Health Professionals Follow‐Up Study (1986 to 2016) with nonmetastatic prostate cancer. Overall and healthful plant-based diet indices were calculated using food-frequency questionnaires. The Expanded Prostate Cancer Index Composite was used to calculate quality-of-life scores.
The researchers found that better scores for sexual function, urinary irritation/obstruction, urinary incontinence, and hormonal/vitality were seen in association with a higher plant-based diet index. In the age-adjusted analysis, but not in the multivariable analysis, consuming more healthful plant-based foods was also associated with better sexual and bowel function and improved urinary incontinence and hormonal/vitality scores.
"Individuals with prostate cancer should be advised that incorporating a greater amount of plant‐based foods into their diet could not only reduce the risk of comorbid conditions but also contribute to improved functional outcomes," the authors write.
