Well, then, since so many millions of Americans have an ancestor from early New Sweden which was populated by Saami foresters -- there must be an epidemic of B-12 Deficiency in this country.
Are you saying that NOBODY who takes Vit.B-12 *ever* develops Alzheimer's Disease, or are you making some kind of joke that I'm too dense to catch?
So, yeah, people with an ancestor or two, or a hundred, or a thousand in and among the original New Sweden or York PA settlements probably have an hereditary B-12deficiency.
The B-12 and beet notes have been discussed earlier. The most recent one using "beet" in the title is at http://www.freerepublic.com/focus/f-chat/2619626/posts
You'll also want to go to http://www.webmd.com/alzheimers/news/20101018/vitamin-b12-linked-to-lower-alzheimers-risk to get started.
Simultaneously with the US and British reports on the topic the Scandinavian researchers put out their own stuff showing a negative correlation of Alzheimers in folks on what amounts to a strictly seafood and meat diet ~
Beets darned near disappeared from grocery store shelves. I went to the local Safeway and took their last two cans! (BTW, that was my first trip outside the house except to the doctor in months ~ the eye thing).
