For 2M years, humans ate meat and little else: study
My father had a mid-life crisis in the mid 90&#x27;s, and went from being an avid hunter and fisherman to being a hardcore animal rights vegan.  (It was all precipitated by him meeting and dating a woman who worked at PETA)<p>He was about 45 at the time.  Within 2 years, his health had markedly declined.  There are healthy vegan diets, but his was an unhealthy vegan diet.<p>Despite no history of heart attacks on either his mother or father&#x27;s side, he developed heart disease in his early 50s.  This was where I first became aware of the scientific fraud that is the lipid hypothesis, and how wrong it is.  The Framinham Heart Study has been a source of data that actively refutes the lipid hypothesis for decades, but the nutritional science community has similar issues to many other organizations with tenured experts whose entire reputation is tied to their theories being right.<p>My experience dealing with militant vegans is that there is no amount or type of evidence that would convince them that a diet that includes ANY amount of animal products is healthy.  It&#x27;s a religion to them, and that&#x27;s that.<p>I was a teen when he converted to veganism, and my encounters with these various activists made me absolutely despise them and their ilk.  Truly contemptible people in general, who fully believe the ends justify any means.
