[edit] Lysine and Niacin

Niacin deficiency can occur when both niacin and tryptophan intakes are low (tryptophan can be converted to niacin in the human body). Lysine, AFAIK, has nothing to do with all that. The niacin page doesn't even mention it, either. Aragorn2 17:12, 15 May 2005 (UTC)

This dubious claim has been removed from the article - no references on the web. Exabyte (talk)­ 03:48, Jun 5, 2005 (UTC)

Is this problem resolved? The article says a lack of niacin and tryptophan causes pellagra, but then says a lack of available lysine in untreated corn is the problem. The link between those two statements is unclear. Lobosolo 02:29, 4 November 2005 (UTC)

Also, the Joseph Goldberger link redirects to here. Shouldn't there be a separate Goldberger entry, even if it's brief? Lobosolo 02:29, 4 November 2005 (UTC)

Well, as you can see the problem is not resolved. The Lysine article says that lack of lysine causes deficiency in niacin. Some quick googling gave me this: The absence of the amino acids lysine and tryptophan, however, make half of the niacin in corn indigestible. [1]
Some more research is probably needed. Feel free to amend the article, or I will at some other time.
Regarding Goldberger, it's stupid to link a redirect back; however, I would avoid creating a substub. Conf 12:59, 4 November 2005 (UTC)
I took a stab at rewriting that section for clarity. I couldn't find much support for the lysine theory, so I de-emphasized it. If you get a chance, take a look at it and see if it works for you. --Arcadian 17:41, 9 December 2005 (UTC)
Anyone want to take a stab at that Goldberger entry? MarcoTolo 00:07, 8 March 2006 (UTC)
Okay, I created a separate Joseph Goldberger entry - have at it.... MarcoTolo 01:00, 13 March 2006 (UTC)

[edit] caused by hexachlorobenzene?

See hexachlorobenzene: "American Pellagra was a disease affecting 250,000 people between 1900-1950 caused by hexochlorobenzene residue from new bleaching and degermination procedures for corn and wheat. Hexachlorobenzene was banned from use in the United States in 1966." --Espoo 09:07, 4 May 2006 (UTC)
