Chocolate covered espresso beans are a common treat, so I don't think they're a universal health threat at least. I'm not sure what problems you found you had after crunching on a few beans, but I wonder what actually caused it. I do have more GI upset when I drink too many of the grounds out of my french press or cupping bowl, but oddly enough I can't say I've ever had any issue with crunching on beans.
Ah, okay. I'll take care to crunch my beans in moderation.
Each coffee bean has more than 10 mg of caffeine in it, which lowers the strength of the esophageal sphincter and causes acid reflux, just like a cup of coffee. Coffee beans themselves are acidic, and decaf coffee beans have been shown to increase gastric acid production without the aid of caffeine. This all leads to a very acidic and potentially extremely uncomfortable situation, above and beyond what the bean juice alone could produce.
This was all just a long way to say: eat them if you like to, don't eat them if they bother you.
