It does not, however, disprove the hypothesis. I made no comment, just posted the research for information. Life isn't a test drive and I don't want to discount any credible research in the hope that it proves wrong. If the NiH and Mayo Clinic are claiming it's a risk at even moderate levels of consumption, I'm paying attention. There's also plenty of evidence that red meat may be bad for prostate enlargement.
Some studies found an increased risk of BPH in men who ate more red meat. But other studies found a decreased risk of BPH in men with a high total protein intake, especially protein intake of leaner forms of protein such as fish.
