I could could copy/paste study after study if you need "science" as proof. :-) And of course there is no unbiased study. Raw milk advocates will prove their point, while others will prove their point as well.
Question: have you ever TRIED raw milk from grass fed cows?
All of this research, bogus studies from all sides usually to sell a product as you mentioned, but where is the personal experience? This is the only source of info I deem even partially credible these days.
I can personally advocate the benefits of fresh, organic 100% grass fed raw cow milk, though I do not have a prostate. :-)
