Sweet Potato Greens and Prostate Cancer

Welcome to Weekly Health Update



New research suggests that sweet potato greens may have a role in prostate cancer prevention and treatment.



SWEET POTATO GREENS AND PROSTATE CANCER

As I discuss in my bestselling evidence-based book, A Cancer Prevention Guide for the Human Race, even conservative clinical research assessments strongly suggest that at least 50 percent of all new cancer cases are linked to modifiable lifestyle and dietary habits.  Polyphenols, a group of powerful dietary antioxidant compounds that I extensively discuss in A Cancer Prevention Guide for the Human Race, have been extensively studied in numerous laboratory and clinical research studies as potential cancer prevention nutrients.  Now, a newly published study suggests that polyphenol-rich sweet potato greens may have significant anticancer activity against prostate cancer

In this new study, which appears in the current issue of the journal Carcinogenesis, an extract of sweet potato greens was first tested in the laboratory with human prostate cancer cells growing in culture.  Molecular studies were then performed, which revealed that sweet potato greens extract shut down important cell growth biochemical pathways in human prostate cancer cells, and accelerated cancer cell death through a mechanism known as apoptosis.  (Interestingly, and importantly, however, sweet potato greens extract appeared to have no adverse effects on normal human prostate gland cells.)

As it is well known that the results of laboratory-based studies often cannot be reproduced in animal or human studies, the authors of this study then implanted human prostate cancer cells into laboratory mice.  These same mice were then fed sweet potato greens extract (400 milligrams per kilogram per day), while another group of mice (the “control group”) did not receive any sweet potato greens extract.  At the end of the study, the scientists conducting this research discovered that the prostate cancer tumors growing in the mice who received the sweet potato greens extract were, on average, almost 70 percent smaller than the tumors growing in the control group mice!  (Once again, there also appeared to be no adverse effects on normal tissues and organs in the mice that received the sweet potato greens extract.)

This research study is the first study to identify significant anticancer effects against prostate cancer associated with sweet potato greens in both cancer cell cultures and in mammals.  The potent anticancer effects of sweet potato greens extract, as demonstrated in this very elegant study, and combined with the apparent lack of toxicity, suggest that this polyphenol-rich vegetable may have a role in prostate cancer prevention and, perhaps, prostate cancer treatment; although it will be necessary to repeat this laboratory study in humans to determine if sweet potato greens have similar anticancer effects in people.

    That would not be true. The region is felild with tiny nerves and the prostate is very sensitive. They inject the prostate with something like Novocaine to dull the sensation before they begin. I had a biopsy a couple of months ago. They insert this ultrasound device into your rectum to help guide them in finding the exact location for the biopsy. they insert the biobsy needles, which are attached to a gun with a trigger. when they release the needle it snaps out really quickly and grabs the surrounding tissue. It isn’t painful exactly, it feel more like being snapped with a rubber band. it gradually becomes more uncomfortable though, and by the 10th one I was ready for them to stop. They took twelve samples. The Dr. told me there might be a little blood in my urine for a few days and some blood in my semen for up to a week. There was a lot of blood! it freaked me out .but it did go away quickly. Other than that, it wasn’t that bad,
