So,  I've been told to wait 20-30 minutes after drinking to eat, and to wait 20-30 minutes after eating to drink.

I think I'm clear on why we don't drink fluids after eating.  A) slows absorbtion since it pushes the food quicker   B) it can expand our pouch   C) makes it so we can eat more


I'm not clear on why we can't drink prior to eating.  Can someone enlighten me as to why it is a bad idea prior to eating?

A) Allows you to feel fuller faster and you may not eat  B) it can expand our pouch   C) makes it so we can eat more
