Kernkonzepte
A predominantly plant-based diet is associated with a lower risk of prostate cancer progression in men after diagnosis and treatment.
Zusammenfassung
This study examined the relationship between plant-based diets and the progression of prostate cancer in over 2,000 men. The researchers used two dietary indices - the Plant-based Diet Index (PDI) and the healthful PDI (hPDI) - to assess the proportion of plant-based foods in the participants' diets.
The key findings are:
- Men who consumed the most plant-based diets according to the PDI had a 47% lower risk of disease progression compared to those in the lowest PDI quintile.
- For men with aggressive prostate cancer (Gleason score ≥ 7), those in the highest hPDI quintile had a 55% lower risk of progression compared to the lowest hPDI quintile.
- The study did not examine vegan or vegetarian diets specifically, as even the highest PDI quintile participants consumed some meat and dairy products.
- The researchers concluded that a predominantly plant-based diet in men with prostate cancer may be associated with better prostate cancer-specific outcomes, and dietary assessment and counseling could be beneficial.
Statistiken
Men in the highest PDI quintile had a 47% lower risk of disease progression compared to the lowest PDI quintile.
For men with aggressive prostate cancer (Gleason score ≥ 7), those in the highest hPDI quintile had a 55% lower risk of progression compared to the lowest hPDI quintile.
The study followed 2,062 participants for a median of 6.5 years after they completed the food frequency questionnaire.
During the follow-up period, there were 190 cases of prostate cancer progression and 61 prostate cancer-specific deaths.
Zitate
"What makes this relatively high-profile published study interesting is that it examined whether diet is relevant for the recurrence of prostate cancer in over 2000 men with 6.5 years of follow-up after diagnosis."
"It may be beneficial to assess the diet of prostate cancer patients and offer nutritional counseling as needed to establish healthy eating habits and support well-being and overall health."
