I recently did a search for products that contain caffeine. Products we don't expect to contain caffeine, I should say. I have a caffeine allergy and have to be more and more careful these days. I had not suspected the Bloody Mary I ordered at the bar would contain caffeine. I've since learned that there is in fact caffeinated vodka and caffeinated Bloody Mary mix. Quite a good idea.
I knew about all the energy drinks and sodas of course but had no idea we have caffeinated: granola, gummy bears, beef jerkey, hot sauce, ice cream, oatmeal etc. Not to mention all the restaurants that put coffee and chocolate in their short rib, pot roast, chili recipes.
Wow! I'm surprised schizophrenia isn't an epidemic. Are you concerned about your caffeine intake?
P.S. Why hasn't anyone figured out how to make decaf chocolate??
