Here’s an eye-opening example of how delicious we look to lions.  There’s a zoo in China that features a glass partition between the visitors and the big cats.

Somebody filmed a one-year-old boy with his back to the glass while a lioness tries to paw him.  Then she OPENS her massive jaws and attempts to eat the kid.  He doesn’t see that happen, but when he does turn around he tries to pet her.
