MIAMI – A vegetarian or vegan diet may offer some protection against prostate cancer and other sexual health problems, according to a systematic review.
Twelve of the 23 studies that met the criteria for review inclusion looked at prostate cancer, and data from large enrollment trials indicated a link between a plant-based diet and a reduced risk of prostate cancer, reports Nathan Fertag, MD, a medical student at Albert Einstein College of Medicine. In New York City, in North American Society for Sexual Medicine (SMSNA) Annual Meeting.
“Medicine has moved to a more holistic approach in general, however, and more researchers are beginning to look into it [the question of] Can we use these plant-based diets to help manage and prevent conditions like prostate cancer and erectile dysfunction [ED]benign prostatic hyperplasia, [BPH]? ‘ said Feiertag MedPage today. “There were relatively few studies we were able to find for this literature review, but this is the current situation.”
as such vegetarian diets It is gaining popularity, more patients may try it. Feiertag said plant-based diets have shown health benefits for patients diabetic And the HypertensionHowever, little is known about its benefits for prostate cancer, impotence, and benign prostatic hyperplasia.
Erwin Goldstein, MD, of the University of California San Diego, contacted Feiertag after the presentation to invite him to provide the data to Sexual Medicine Reviews. Goldstein is the magazine’s editor-in-chief.
“I need more information because in order to claim that a certain diet really positively affects sexual function, that would be great, but it has to be real,” Goldstein said. MedPage today. “I would like to be in a position to say that there are pharmacological strategies, surgical strategies, but there may be [also] Only conservative lifestyle changes [you could make for ED]. “
Feiertag . said MedPage today That “Urologists can consider our review as an opportunity to incorporate or modify existing diet counseling for their patients, especially those eager to implement lifestyle changes, particularly with regard to prostate enlargement, ED, and prostate cancer.”
The researchers evaluated mostly cohort studies, along with cross-sectional studies, and a small number of randomized controlled trials. It has included data from vegetarian diets, vegan diets, and vegetarian diets, such as the Mediterranean diet. Several small cohort studies showed a significant reduction in the velocity of prostate cancer, although the benefit did not last at 6 months, Fertagh reported.
Two of the five ED studies reviewed found an association between plant-based and improved diets International Index of Erectile Function scores, although one reported worse scores. The two studies included in ED reported a lower relative risk of ED for patients following a vegetarian diet. Five of six studies on BPH found that vegetarian diets were inversely associated with the development of BPH.
Feiertag and colleagues note in the SMSNA Abstract that the results were not generalizable because the trials were limited to observational and cohort studies that relied on patient-reported diet assessments. They said more high-quality studies are needed to assess the relationship between diet and urinary tract conditions.
However, no studies have reported unrelated or harmful effects of a vegetarian or vegan diet. “For patients who want to change their diet, this is good for them. It certainly won’t hurt,” Fertag said. MedPage today.
Feiertag and the co-authors have not disclosed any ties to the industry.
