Beware of nutritional yeast

15 May 2009

Although nutritional yeast is a good source of vitamins and minerals, including
folic acid, it is nonetheless very high in glutamate, which is a major excitatory
neurotransmitter in the central nervous system. As a result of its high
glutamate
concentration, yeast is moderately addictive and can cause or aggravate asthma
and headaches. Despite its nutritional and flavor-enhancing properties, it is
best
to avoid glutamate in all its forms, including the ubiquitous monosodium
glutamate.
