Interesting, also interesting that this is a 9 year old article. I'm surprised that the elderly are noted as not getting enough sulfur, because I believe eggs are a good source and (barring incidents like the avian disease outbreak last year) are a generally inexpensive source of protein as well.
My experience is that older people fear eggs because of the bad campaign against them in the 80s (70s?).
Can't eat eggs, they have cholesterol!
It is somewhat depressing how much of the stuff we have done "for health reasons" ends up being less healthy than the original.
