Supplements and prostate cancer prevention
A recent article by Collins on the CalorieLab web site offers a sound summary of “where we are” with regard to the use of supplements in the prevention of prostate cancer.
Perhaps surprisingly (since there are at randomized Phase III clinical trials with the product ongoing), Collins makes no mention of pomegranate juice/extract.
According to author's opinion, some experts believe that efforts to identify specific nutrients or compounds for supplementation may be better spent elsewhere, focusing on healthy dietary patterns and lifestyle habits, for example.
In his update Collins emphasizes the following major issues:
- Selenium, vitamin D, and vitamin C supplements failed to demonstrate any impact on prevention of prostate cancer in recent, very large, randomized clinical trials (in the doses and formulations used in these trials).
- Research is ongoing on isothiocyanates — natural compounds found in broccoli and other cruciferous vegetables.
- Research is continuing on the potential of lycopene, a cousin to beta-carotene and a powerful antioxidant, which is commonly found it tomatoes (although a small, recent trial showed no evidence of clinical benefit in late stage disease).
- Several compounds found in garlic offer antioxidant, anti-inflammatory, and specific anti-cancer effects and can affect PSA levels in later stages of prostate cancer development.
- Products in other foods, such as green tea, flaxseed, soy, and perhaps other beans may help to prevent prostate cancer, although no evidence of a direct link to lower prostate cancer risk has been established as yet.
- Excessive amounts of milk or high doses of calcium (more than 1,500 mg daily) may increase prostate cancer risk. ts were recently presented at the 26th World Congress Endourology meeting in Shanghai, China.
