Diet tips - pomegranates and blueberries and vitamin D?

Postby janet.parks » Sun May 01, 2016 3:18 pm

Hi everyone,

Would like some tips on diet for my husband. We have been told about how effective pomegranates and blueberries can be so he’s consuming more of them, also cutting out dairy/red meat and trying more soya instead (to replace meat and milk). But really, how effective is this? Not expecting it to prevent PCa completely but is it significant?

I’ve also heard low vitamin D is linked to PCa - is this true and would you recommend supplements to counter this? Any other tips on diet, what should he be eating and avoiding etc.?

Hi, Janet and thanks for your questions.

We know from twin studies and migration studies that the risk of getting prostate cancer rises significantly when men move from the poorer parts of the world to more affluent countries. For instance, a Vietnamese man living in the USA has a much greater risk of developing prostate cancer than his identical twin brother living in Vietnam.

We think that the most important environmental factors that cause this difference in prostate cancer risk are diet and exercise. We now have good evidence that the risk of getting prostate cancer is higher in overweight/obese men and that if they get it, it tends to be more aggressive. We also have good evidence that the saturated fat found in red meat and dairy products is relatively harmful, just as the antioxidants and phytoestrogens (natural plant compounds that behave like the female hormone oestrogen) found in fruit and vegetables are relatively protective. So the best advice to prevent prostate cancer naturally is to exercise regularly, keep your weight down, eat red meat and dairy products sparingly and eat lots of fruit and vegetables regularly.

As far as vitamins, supplements and trace elements are concerned the landscape seems to be quite fluid. A good example of this is Vitamin E, which at one stage was thought to be helpful in preventing prostate cancer but has recently been shown by the SELECT study to increase the risk of developing it when given alone.

Other supplements that have been suggested as being useful in reducing the risk of prostate cancer include:-
• Vitamins A, C and D.
• Lycopene (found in tomatoes).
• Green tea.
• Soy products, pomegranate, broccoli and turmeric.

It seems that a diet that is rich in saturated fat also increases the aggressiveness of prostate cancer - another reason to avoid it http://www.practiceupdate.com/c/38431/3/0/?elsca1=emc_enews_top-10&elsca2=email&elsca3=practiceupdate_uro&elsca4=urology&elsca5=newsletter.
