Why Do Humans Have a 'Gut Feeling'?

Your gut feeling is like having a helper inside your body that talks to your brain. When you eat something, or when something scary happens, it sends messages up to your brain so you can decide what to do, like choosing between two ice creams or jumping out of the way of a falling object.
