I remember reading some threads in the past about cravings for certain kinds of foods and what deficiency in the body they might be signaling. I tried doing some searching, but couldn't find exactly what I was looking for.
Anyways, does anyone know if constantly craving vinegar is a sign of something else going on? Why would someone crave vinegar? The person whom I am speaking of will drink vinegar straight from the bottle because of the cravings. He also craves sour things. Any thoughts?
