Great points, as usual. Perhaps some of those answers are in the full text of the study – which I unfortunately don’t have access to.

re: Vitamin D and elderly men/prostate cancer

I would think that such a connection might be apparent by now. A recent meta-analysis didn’t find any link between D and prostate cancer incidence or mortality:

Other reviews have found mixed but similar or slightly protective effects of sunlight and PC risk and severity:

Though more research is needed due to conflicting findings:

Also, it’s important to note that Vitamin D analogs are currently being evaluated as treatments for PC:

It’ll be interesting to see what the future holds. Hopefully some more definitive answers.

I’ll do my best to return the favor when I next visit your site – by adding any constructive input I can think of!

The Vitamin D increases Testosterone in Men Study, was done on nearly 3,000 men who were being tested for coronary artery stenosis and they were probably middle aged/elderly men.

It would have been more interesting if they had included details of whether those who had coronary disease were more numerous in the lower vitamin D level group than those in the higher Vitamin D level. I think they missed a trick there!

As these men were also getting on they probably had a few prostate cancer cells.

The jury is still out on whether higher T levels are good for elderly men or not, due to some studies showing it increased the spread of prostate cancer cells and can be associated with the more aggressive form of PC. On the other hand some studies show the opposite.

I think older men should be aware of this conflict on higher T levels for elderly men, before taking very high doses of T or Vitamin D.

I personally prefer more in-depth articles when it comes to health, as I am of the opinion that these complex topics cannot possibly be answered in just one paragraph. I am convinced that optimal wellness can only be achieved with a combination of diet, supplements, exercise, and proper mind/body practices. Many times I feel that “headline” style articles isolate the topics and make it sound like each individual topic is the “solution,” when really it is just the tip of the iceberg.

I am really a fan of your current writing style! My only suggestion would be adding “sections” to longer articles, so that the reader can easily skip to the section that is most interesting to them. But again, I am just learning myself, and would like to hear any feedback that you have for me!
