Sorry about the duplicate post on this topic one day last week. The copy was
intended for an individual, not the list.
On my latest visit to a hfs, I took a closer look at the KAL yeast bag and
made a surprising discovery. (When Tracy was looking for yeast that has zinc,
I posted that KAL brewer's has a natural presence of 3.1 mg zinc per 15
grams.) Even though the label says "brewers" in large lettering, the contents
are actually nutritional yeast! This was evident because the word "primary"
was on the label. I called KAL for clarification. The reason the label says
"brewers" is simply tradition. The company was selling inactive brewer's
yeast as a nutritional supplement before what is called nutritional yeast
came into existence. Because the species of yeast didn't change, no need was
perceived to change the name "brewers" to "nutritional," even though the
yeast is now grown on blackstrap molasses.
