I may be very off on many scientific details here, but I'm always all ears.
As far as I understand, any food that is eaten goes to the stomach, gets broken down even further into smaller food molecules, and after a period goes through the intestines where nutrients are absorbed out of this... stomach-output.
Let's say I eat food A sometime, and it's gone down and is now sitting in my stomach, waiting for the stomach to start breaking it down. After a while, I eat food B.
When digestion occurs, is it possible that the stomach only starts breaking down food A's material first before it gets to food B? Is it possible that food B's output goes into the duodenum before food A's output?
Please help break any of this down if it's obvious I've been living in a cave. Thanks!
