A recent study published in JAMA Network Open examined the impact of plant-based diets on the progression and recurrence of prostate cancer in men. The study found that individuals with the highest intake of plant-based diets had a 47% lower risk of the disease progressing or recurring compared to those who primarily consumed meat and dairy-based diets.
The researchers pointed out that fruits and vegetables contain phytochemicals that have been shown to protect against prostate cancer, while plant foods are a source of dietary fiber that can promote satiety and regulate blood glucose levels. On the other hand, animal-based foods like meat and dairy have been associated with increased exposure to potentially harmful substances and have been linked to increased insulin resistance and prostate cancer risk.
Lead author Vivian N. Liu and her colleagues analyzed data from 2,062 men with prostate cancer as part of the Cancer of the Prostate Strategic Urologic Research Endeavor (CaPSURE) study. They found that participants with high intakes of plant-based diets had better outcomes, including a lower body mass index and reduced likelihood of smoking.
The researchers emphasized the importance of incorporating more nutrient-dense plant-based foods into the diet, such as vegetables, fruits, and whole grains, to improve prostate cancer outcomes. They also highlighted a previous study that reported a 19% lower risk of fatal prostate cancer associated with plant-based diets.
Overall, the study suggests that adopting a plant-based diet may be advantageous for individuals with prostate cancer. By reducing intake of animal products and focusing on nutrient-rich plant foods, individuals may improve their overall health and potentially reduce their risk of prostate cancer progression or recurrence.
