Website SciTechDaily reports results of a large study (n = 16,000 adults) finding animal and plant protein in the diet was not associated with higher mortality rates. And that wasn't the most exciting finding.
The results revealed no elevated risk of death linked to greater animal protein intake. Instead, the data pointed to a small but meaningful decrease in cancer-related deaths among people who consumed more animal protein.
It is what I'd expect to find for a predator hominid species like ours. Hat tip to Instapundit for the link.
Reminder: correlation does not prove causation. It is possible affluence enables more animal protein in the diet and also enables healthier behavior.
