This story raises a whole lot of questions. I'm going to copy the journal article when I get down to the medical library Monday (having another echo-
please pray or send positive vibes) so I can read the specifics.
High-Fat Diet Linked With Impaired Brain Function found in Neurobiol Learning Memory 2001;75
---------------------------------------------------------------------------

WESTPORT, CT (Reuters Health) Feb 22 - The results of animal studies suggest that a high-fat, carbohydrate-poor diet may impair brain function over time, according to researchers at the University of Toronto.
Rats that were fed high-fat diets were slower in learning new tasks compared with rats fed a standard diet, investigators report in the March issue of Neurobiology of Learning and Memory. The high-fat diet animals also performed more poorly on tests of learning and memory.
The study authors, Drs. Carol Greenwood and Gordon Winocur, believe high-fat diets may hinder brain function by promoting insulin resistance. "At this point, we believe the link [between high-fat diets and impaired brain function] is diabetes," Dr. Greenwood said. This theory, she told Reuters Health, supports work suggesting that diabetics often suffer a decline in certain mental functions such as long-term memory.
Moreover, Dr. Greenwood and her colleagues have evidence from human studies that carbohydrates may boost memory. In a small study of older adults, they found that a "breakfast" of mashed potatoes or barley increased participants' performance on memory tests.
Dr. Greenwood explained that a diet lacking in carbohydrates reduces the supply of glucose, which can impede the acetylcholine synthesis.
In the current study, the investigators found that the test performance of the memory-impaired rats improved after glucose injections.
However, this does not mean that adding carbohydrates to a high-fat diet will prevent any ill effects on the brain. "My argument," Dr. Greenwood said, "is to displace the fats with carbohydrates." _ _ \|/(_)_(_)\|/ @~ (o.o) ~@ /___( * )___\ Maureen in Mukilteo / `U' \ k...@ix.netcom.com ( . ) `>---<' No information in this post should be taken as a _\ /_ recommendation.

Hmmm. I'd be interested to learn what kind of fat was in that rat feed. IMHO, EFAs, while fats, are more likely to improve brain function than impair it.
Even a certain amount of cholesterol is necessary for proper brain function. I could more likely see it, though, if the fats were saturated fats.
And what's a "carbohydrate poor" diet? None? Very little? How much carbos in proportion to the fat? Not enough info here.
Whaddya think?

Heh, heh... well, Maureen's going to ferret (!) it out, never fear...
Maybe they gave 'em crankcase oil, who knows?
I figure they're in the soup and just snatching at straws myself. As long as the high fats are things like salmon oil and other related antioxidants (like ALA) I can't see how brain function would be anything but improved myself.
This one looks like a real clunker but I'm going to wait for Maureen to get us the whole enchilada.
I don't think I've ever had an enchilada. Sam? what's an enchilada?
Love from Mrs Magoo

<<Monday (having another echo- please pray or send positive vibes) >> Maureen, I am totally sorry - I read this and was so taken with the rest of your post that this item fell out one of the holes in the seive I call my brain. I am so sorry - I forgot until I saw Sammie's post. So of course you ought to be getting all sorts of good wishes and healing thoughts etc etc and especially I do hope that the results are top notch. Please do let us know what happens. I suppose this is going to be first thing in the morning kind of thing. I will be thinking of you.
Love from Mrs Magoo ;-)

Well, I don't make 'em 'cause they're hard to make (I think) but basically it's a meat, chicken or bean filling (sorta like taco filling) rolled in a corn tortilla, covered with a tomato-based sauce, covered with cheese and baked in the oven till the cheese is melted. They're pretty good - when somebody else makes them. When I try to make them the traditional way, everything just seems to fall apart on me and I end up with a great tasting conglomeration instead of nicely rolled enchiladas!
Oh, and when made traditionally, they're pretty high in fat. Sam in Texas ?§(??????)?§ Minds are like parachutes; they function best when open.

You are in my prayers.
Good luck finding the specifics of this article--your delving into this sort of thing is one of the reasons I keep coming back to this group after all these years!
