If you're open to alternatie medicine, traditional Chinese medicine (and probably ayurvedic medicine) splits food into hot/cold groups that affect your body's balance. My personal armchair doctor explanation is that the inside of the mouth experiences a lot of small cuts, but our immune system takes care of those before they turn into larger wounds. When your immune system is weaker, or your mouth is drier, then those small wounds open into larger ones.
