What makes it taste so good when it is so bad for you? Fat! Salt! Nitrates! Processed meat! Cholesterol! I have had a number of relatively observant Jewish friends over the years, and the one pork product that they did not even try to resist was bacon. As for my Muslim origin friends, they were not observant, but in any case they ate bacon, too. Apparently it is very hard to resist. I wouldn't be surprised if a number of vegetarians eat bacon in secret.
Actually, I was reading up on it a bit, and it is not quite as bad as was once thought. About half of the fat is fat that is "good" for you (within reason), and as for cholesterol, apparently the cholesterol that you consume in food is not nearly as bad as the cholesterol that your body makes all by itself. Bacon is full of B vitamins, which is good -- but lots of other food has B vitamins, too. Nitrates are carcinogens when you fry them. Oops.
And then there's the salt. Not much you can do about that if you still want it to taste like bacon...
I do love bacon but don't find myself eating it very often.
The flavor is outstanding.
The last time I had bacon in some form was at lunch where I had a soup that was a cream based soup that had oysters in it and was flavored with anise and small slices of bacon (not "bacon bits" which are an abomination!).
Without the bacon the soup would have been bland and tasteless.
