There isn't really much evidence that meats in general are bad for you.

There is some evidence fatty meats or red meats aren't good for you.

There is more evidence that fatty red meats are bad for you.

And there is a lot of evidence that heavily processed(specifically cured) red meats such as hot dogs and bacon are bad for you.

Or you can just google cured meats mortality, bacon mortality, etc...
