Eat prunes to swallow the core. Can you eat the kernel of prunes or not? Doctor's words have authority. The prunes are able to help digestion, but the prune kernel is, after all, hard, eat into the stomach and intestines certainly will not be digested, eat more, but also may get intestinal obstruction. In fact, unintentionally eat a small amount of prune kernel does not matter much, but do not consciously go to eat a lot of prune kernel.
