All fat and protein, won’t spike your blood sugar at all.

In my original articles on the subject, I argued that the real reason for the bacon-mania explosion has to do largely with the intersection of taste and economics. Simply put, factory farming churns out huge amounts of cheap but tasteless foods. Bacon (and cheese) becomes a quick fix for the processed- and fast-food industry. Essentially, pile on bacon and cheese to almost anything — potatoes, salads, soups, meats and now even desserts — and you add a riot of flavors and aromas for just a few pennies more but you can charge a couple of dollars more.

There are also important cultural trends like the locavore movement and bacon as a signifier of masculinity and rejection of “feminine” diet and healthy eating, but the restaurant industry slogan says it all: “When in doubt add bacon and cheese.”
