Is there any actual science behind the claims that meat is bad from a health perspective? From what I've seen it looks similar to the "science" that told us that eggs were bad, and that we should avoid fat at all costs--in other words, a bunch of loose correlations from studies with poor reproducibility and poor controls.

In the US, red meat consumption per capita has dropped over the last 50 years, suggesting that it is not the major contributor to our current health problems that some claim.
