Fish oil diet could slow prostate cancer progression, study suggests
A groundbreaking study has revealed that a high omega-3, low omega-6 diet, supplemented with fish oil, could significantly slow the progression of prostate cancer in men on active surveillance. The findings, published in the Journal of Clinical Oncology, suggest that dietary changes could be a powerful, non-invasive tool for managing the disease.
What the Study Found
The CAPFISH-3 trial, conducted at UCLA, tracked 100 men with low-to-moderate-risk prostate cancer over a year. Participants were split into two groups: one followed a diet rich in omega-3 fatty acids with fish oil supplements, while the other maintained their regular diet.
By the end of the study, the group on the specialized diet saw a 15% reduction in a key cancer biomarker, the Ki-67 index, which is linked to tumor growth. In contrast, the control group experienced a 24% increase. While secondary outcomes, such as tumor grade and PSA levels, showed no significant changes, the reduction in the Ki-67 index is a promising sign.
Challenges and Benefits
The dietary intervention wasn’t without its challenges. Four participants withdrew from the study due to adverse reactions to fish oil. Despite this, the findings highlight the potential of dietary changes to complement existing treatment strategies.
Lead researcher Dr. William J. Aronson said, “This study underscores the role of diet in influencing cancer progression and offers hope for men seeking non-invasive options while on active surveillance.”
Implications for the Seafood Industry
The findings may also benefit the seafood industry. With fish oil as a primary source of omega-3 fatty acids, salmon and other fatty fish could see a surge in demand as consumers seek natural ways to improve their health. The study reinforces long-held beliefs about the health benefits of omega-3-rich diets.
The researchers plan to conduct larger trials to confirm the findings and explore whether the diet can have long-term impacts on survival rates. For now, the study offers a beacon of hope for men looking to actively manage their condition through lifestyle changes.
