A new study published in JAMA Oncology suggests that a healthy diet may help men with low-grade prostate cancer reduce the likelihood of cancer progression. Conducted by Johns Hopkins Medicine researchers, this study is among the first to provide scientific evidence linking high-quality diet adherence to a slower progression of prostate cancer among men undergoing active surveillance. Active surveillance is a strategy for low-risk cancer patients who avoid immediate treatment, opting instead for regular monitoring to minimize side effects.
Led by Dr. Bruce Trock, the team studied 886 men diagnosed with grade group 1 prostate cancer. Participants completed dietary questionnaires, and their diets were scored based on the Healthy Eating Index (HEI), which evaluates how well a diet aligns with the USDA’s dietary guidelines. Men with higher HEI scores showed a statistically significant reduction in the progression of their cancer, with a 15% reduction in the risk of advancing to grade group 2 and a 30% reduction for grade group 3.
Researchers also explored the potential link between diet-related inflammation and cancer progression, though they found no strong correlation. These findings offer promising insights for men on active surveillance who are motivated to adopt dietary changes. However, further studies with more diverse populations are needed to confirm these associations and develop concrete dietary recommendations.
