Does plant-based diet improve sexual health in men with prostate cancer?

A new study published in the journal Cancer linked a plant-based diet to fewer side effects experienced by people treated for prostate cancer.
Prostate cancer is one of the most common cancers among men worldwide. Statistically, it is estimated that approximately one in every eight men will be diagnosed with prostate cancer during their lifetime.
A diet rich in fruits, vegetables, whole grains, and lean proteins supports men with prostate cancer by providing essential nutrients and antioxidants, boosting the immune system, and protecting cells from damage. Foods high in omega-3 fatty acids and healthy fats, like fatty fish, flaxseeds, and nuts, reduce inflammation and promote overall well-being. Limiting red and processed meats and incorporating soy products and a plant-based diet can also have protective effects against prostate cancer progression.
In the study, researchers looked at more than 3,500 men with prostate cancer and classified them into five groups based on the proportion of animal versus plant-based food the men reported eating.
The researchers found that the group consuming the highest proportion of plants scored 8% to 11% higher in measures of sexual function, compared with the group consuming the least. Results also showed up to 14% higher scores for urinary health, with fewer examples of irritation, obstruction, and incontinence.
The highest group of plant eaters also demonstrated up to 13% higher scores in hormonal health, assessing symptoms such as depression, hot flashes and low energy, compared to the lowest group on plant-based diets.
“Our findings offer hope for those looking for ways to improve their quality of life after undergoing surgery, radiation, and other common therapies for prostate cancer, which can cause significant side effects. Adding more fruits and vegetables to their diet, while reducing meat and dairy, is a simple step that patients can take,” said Dr. Stacy Loeb, a urologist and the study’s lead author.
