Is their some sort of study out there that finds the correlation to be causal?
I've seen some that suggest that, but I'm on an anecdotal basis for my question. I've never attempted a literature search on the topic.
I did a search on the link between red meat and heart disease and discovered that most of well done studies suggest that red meat greatly reduces the risk of heart disease, with the caveat that you don't want to be greatly overweight. Beef being such rich food that a 10-ounce steak every day isn't necessary.
