Bacon is ok, Kool-ade is bad.
From what I can tell, it isnt the best choice but dang it taste good. I think the biggest issue is that it is difficult to get "clean" pork sources. The hormones and antibiotics used in farmed pigs tends to collect in the fat areas, which end up being bacon. I dont know exactly how accurate that is but it seems to make sense. Same really with beef. Fatty grass fed beef is great but if eating more conventional sourced beef, it is probably better to go leaner.
