The impact of diet on prostate cancer prevention and recovery has been a very hot topic for medical research over the last year. Not surprisingly, the same things that help heart function and weight are proving beneficial to reducing risk of prostate and other cancers, and reduced risk of rising PSA’s after treatment.
Here are some interesting findings from recently-published research: A current survey of recent literature supports the role of specific foods in reducing the incidence of prostate cancer. Vitamin E and D, selenium, quercetin, Omega 3 fatty acids, carotenoids, and lycopene are among the products receiving special focus in research. Dark green vegetables like spinach, asparagus and broccoli are great sources of many of these compounds, as are intensely colored veggies like peppers and carrots. Green tea contains EGCG, a compound believed to provide a strong anti-oxidant effect and is used in several anti-cancer treatments.1,2 We know these foods are good for us, and now we know that they are good for your prostate health so eat more of them!
Research on a number of risk factors has indicated a diet high in Omega 6 fatty acids may increase prostate cancer risk, while Omega 3 fatty acids in our diet may reduce risk. Research using mice with a genetic propensity for prostate cancer showed a significant reduction in cancer cell proliferation when consuming a diet high in Omega 3 fatty acids. Even study mice that had a regular diet high in Omega 6 fatty acids showed a big improvement when changed to an Omega 3 rich diet.3
Omega 3 fatty acids offer big benefits for your heart and circulatory system too. Good Omega 3 fatty acids show up in organic range-fed meats and eggs, and a variety of cold-water fish.
Omega 3 fish oil capsules are easy to find in vitamin supplement isles, and Omega 3 rich meats and eggs can be found in most grocery outlets.
While the research is still ongoing, we might safely assume that what is good for reducing the risk of prostate cancer is going to benefit you after your diagnosis and treatment as well– and there is some evidence that post treatment changes can help.
A recent look at eight survivor observational studies and 17 intervention or lab studies showed a diet high in plant-based nutrients and reduced meats and dairy, may serve as an important additional treatment in reducing the risk of recurrence or advancement of prostate cancer.4
While much of this food-based research may aid in prevention or recovery, it is not a substitute for careful monitoring, nor is it a replacement for surgery or radiation if a diagnosis of prostate cancer is obtained. Bottom line: A smart, green diet is one part of optimizing your health that helps reduce your risk of developing prostate cancer and can speed recovery for those undergoing surgery. And it can be pretty enjoyable eating too!
