Any study that happens to support global warming activist propaganda (red meat is bad for the planet) is automatically suspect.
“Scientists” everywhere have been given their marching orders
As a scientist, I post to forums like this to try to explain the difference between methodologically sound science, and "studies" like this one that start with a conclusion and gather "data" to support it.
Publishing this kind of bilge, blaming one kind of food while failing to point out (even in the peer-reviewed publication) that the study actually compared the effect of eating balanced vs. unbalanced diets and drawing politically correct conclusions makes all scientists look bad.
I very much want scientists to keep looking good--after all, few professions are respected as much as science, and I would like to keep that respect.
Only the ones who live by the grant.
The rest of us are free to think.
