Pflanzliche Ernährung ist ein Segen für Männer mit Prostatakrebs

Recent research suggests that a plant-based diet low in dairy and meat but rich in fruits, vegetables, grains, and nuts can improve sexual health and urinary health in patients being treated for localized prostate cancer.

These findings, published February 13, 2024, in the journal Krebs, support previous research showing that a plant-based diet can reduce the risk of recurrence and improve survival outcomes for men with prostate cancer.

„The current study, for the first time, shows a correlation between consuming more plant-based foods and improved quality of life outcomes in patients diagnosed with prostate cancer,“ said Stacy Loeb, MD, a urologist at NYU Langone Health in New York City, who led the research.

Loeb and her colleagues analyzed data from over 3,500 men with prostate cancer as part of the Health Professionals Follow-Up Study, which began in 1986 and is sponsored by the Harvard TH Chan School of Public Health. The dataset included over 50,000 male dentists, pharmacists, optometrists, osteopaths, podiatrists, and veterinarians.

The average age of prostate cancer diagnosis was 68 years, with 48% of patients undergoing radical prostatectomy and 35% receiving radiation as primary therapy. None of the patients had known metastatic disease.

Participants completed a food consumption questionnaire every four years, as well as a biennial survey assessing other health issues, including the frequency of incontinence, erectile dysfunction, as well as bowel, energy, and mood problems.

Loeb and her colleagues divided the patients into quintiles based on the proportion of plant-based versus animal-based food that they reported consuming. The authors found that those consuming the most plant-based foods had 8–11% better scores in measures of sexual function than the group consuming the least of these products.

These men also reported up to 14% better scores for urinary health, with fewer cases of incontinence, constipation, and irritations, as well as up to 13% better scores for hormonal health, characterized by symptoms such as fatigue, depression, and hot flashes.

Justin Gregg, MD, a urology researcher at MD Anderson Cancer Center, and Kenneth Jacobsohn, MD, Professor of Urology and Director of Lifestyle Medicine at the Medical College of Wisconsin, commented on the study’s findings, highlighting the positive role of dietary quality and plant-based nutrition.

Jacobsohn noted that the study was limited by its retrospective nature and the type of dietary assessment used, but emphasized the importance of considering compelling data about the protective effects of plant-based diets on the risk of cardiovascular diseases, especially for men with a history of prostate cancer.

Loeb, Gregg, and Jacobsohn reported no conflicts of interest. Some of the study authors disclosed a variety of potential conflicts.
