What is the most unhealthy meat to eat?

Could you elaborate on what makes a particular type of meat the most unhealthy to consume? Are we talking about the fat content, the processing methods, or perhaps the presence of harmful additives? Is there a specific type of meat that consistently stands out as the least healthy option, and if so, what are the main reasons behind this classification? Additionally, are there any healthier alternatives or cooking methods that can mitigate the negative effects of consuming this type of meat?
