Health benefits of yeast?

Question

Only want scientific studies of benefits not anecdotal info

Answer 1

Brewer's yeast is very rich in protein, B complex vitamins, all the essential amino acids, minerals such as chromium and numerous others and numerous other nutrients.

A web search for "brewer's yeast" + "health benefits" will give you further and more detailed information.

Answer 2

I am unclear there are any.  You will find there is much more reseach that speaks about its lack of health benefits, depending of course upon what type of yeast you're talking about.  The exception to this would be nutritional yeast, which is an extremely high source of B vitamins.
