How much spit do you produce in a year?

Answer 1

The estimates of saliva or spit production range from 0.75 liters per day to 1.5 liters per day so this is 273.75 to 547.5 liters per year. Now you might wonder how many gallons that is? Well, 547.5 liters = 144.634199 US gallons and 273.75 liters = 72.3170993 US gallons. Now you may wonder what is in all that spit? Well, it has water and electrolytes. Here is the electrolyte composition of spit. * 2-21 mmol/L sodium * 10-36 mmol/L potassium * 1.2-2.8 mmol/L calcium * 0.08-0.5 mmol/L magnesium * 5-40 mmol/L chloride * 25 mmol/L bicarbonate * 1.4-39 mmol/L phosphate Of course there is also mucous which makes it sticky. There is an important immunoglobulin know as IgA and there are some enzymes too that help break down foods. There are also some proteins that are important for your teeth. There are lots of cells both human and bacteria. Also, there is a chemical called Opiorphin which is a very potent pain killer, even more potent than morphine. This is only a partial list, but next time you hock a loogie, think twice about what you are getting rid of.
