is it healthier to eat no meat?

[FlatAssembler]

Cancer gets us all, on a long enough timescale. If you want to scare people you've gotta find something weirder than cancer. You should make a youtube video about how eating meat, even thinking about eating meat... comes with a 7-14% increased risk of ebola.

But that would be obviously false. We know what causes ebola: it's a virus. There is no mechanism by which eating meat could increase the chance of getting it. Regularly taking Aspirin probably increases mortality from it, as the mechanism by which ebola kills is causing internal bleeding and Aspirin increases the chances of internal bleeding, but there is no such obvious mechanism by which meat might increase mortality from it either.
Heme iron (found practically only in red meat) almost certainly does increase the risk of colon cancer. There is mechanistic evidence of that, there is epidemiological evidence of that...
