Hi, Acetone (Propanone, C3H6O) is a natural product of fermentation,
produced from the oxidation of propanol, an alcohol with one more
carbon group than the familiar alcohol ethanol. It is as you know toxic
in large doses, however, "acetone has been shown to have anticonvulsant
effects in animal models of epilepsy, in the absence of toxicity, when
administered in millimolar concentrations (see: Likhodii et al, 2003)."

Don't forget Hutch. People have been eating bread for thousands of
years. Any downsides have been well documented by now.

Take care,

Jim
