Why is swallowing food an essential part of the “experience”?

167 views

When I was younger my brother came up with a plan for how we could eat as much candy as we wanted without actually consuming all the sugar it containes. We would simply chew the candy, giving us the taste and feel, and then spit it out instead of swallowing it.

This did not work as intended. It was, in fact, worse than not having any candy at all. The urge to swallow is incredibly strong and the feeling of dissatisfaction once you spit it out is overwhelming.

To this day I get uncomfortable thinking about it.

What gives?

The entire point of eating is to get calories to keep you alive. Spitting out the food does not achieve that goal. There is a *very* strong evolutionary imperative baked in at a low level to eat so you don’t die; this is why high calorie foods (like candy) taste so good.

Your brain has evolved to make you feel good when you do things that are more likely to keep you alive (in an evolutionary sense). This means, among other things, don’t spit out the tasty food.
