What not to eat

I'm reading capsule endoscopy studies again (I'd put in a link to my previous rants/posts on the subject, but I don't know how). I learned some valuable info about Chicken n' Stars soup, which I used to really like growing up. The stars don't digest. Stomach acid, pancreatic enzymes, and 5 hours in the small bowel aren't enough to digest the stars. I know this because I spent 30 minutes watching stars, and the occasional bit of stringy chicken, travel through someone's digestive tract. OK, now I'm hungry.
