In Japan, the phrase Autumn appetite (食欲の秋) explains the special tastes and hungers of the Fall season. Today my sense of taste was uncommonly acute. Perhaps it is the Autumn air, perhaps it is biorhythms, or perhaps it is from taking 1200 mg of the dietary supplement Quercetin this morning.
Quercetin is a flavonoid derived from apples, berries, tea, onions, etc. presently under intense study by DARPA for the US military. It reportedly can bind to viruses and bacteria to stop them replicating, stimulating immune response (see New Scientist 2007-09-19, p.10); I got my Quercetin from Vitamin World.
