Consumer Reports latest health bulletin also pushes Brazil nuts as a defense against Alzheimers.
Apparently selenium is some pretty good stuff, but it can be overloaded, which is why only one or
two nuts a day is recommended.

Too bad most of them are hard to get into. If I am buying them loose I
shake every one.

I ordered a pound of shelled ones from Amazon. A pound will probably last a year.

How do you store them. I find the ones I get at Christmas are garbage
by Easter (gummy with a funny taste)

Ziploc bag in the freezer.



I figure I've received a lifetime of selenium resulting from several
projects back in the 80's. I was involved in designing, testing and
running several high vacuum deposition systems that coated aluminum
drums with selenium (which is a photo receptor material) used in
copying machines used during that period. Built them for Ricoh,
A.B. Dick and other, replacement drum manufacturers. The smell and
dust buildup when you opened the deposition chamber is still burned
in my mind.

Does burning up a rectifier count?



Depends on how many I suppose. I remember as a little kid
the family Motorola black and white TV had
the selenium rectifier go bad. Nothing you had to
guess at.


This was a really big one. The plates were about 4" square and there
were a bunch of them, just not quite enough for 120vac in.
I think it was rated for 48v or something once I investigated it.
Then I found out a tiny silicon diode would do the same thing.
This was in the early 60s and I didn't really know much about silicon.
I never touched selenium since.
It did put on quite a show before the breaker popped and I am sure I
got a lifetime supply of selenium dioxide smoke.
The apartment needed a good airing out too.
