What is the nutritional value of snot?
Well, basically snot is dried mucus plus whatever you accidentally breathed into your nose, often hairs, dirt, dust etc. Mucus flows continually through the nose to stop harmful bacteria and everything else from being able to enter your body through the nasal passage, but hardens and then either falls or is sneezed out. It is a way for your body to remove unwanted materials, hence the nutritional value is pretty much 0. It will contain a bit of salt in it because excess salt is excreted through the same glands which produce the mucus, but this is of course excess salt so you don’t even get the benefit of that.
