It looks like just another “One More Reason to Drink Coffee” article…
A coffee with your doughnut could protect against Alzheimer’s disease
A daily dose of caffeine blocks the disruptive effects of high cholesterol that scientists have linked to Alzheimer’s disease. A study in the open access publication, Journal of Neuroinflammation revealed that caffeine equivalent to just one cup of coffee a day could protect the blood-brain barrier (BBB) from damage that occurred with a high-fat diet.
The symbiotic relationship between coffee and donuts is proven!
Oh wait. It seems they are saying that the major problem with eating a donut is that it is high fat – not that you’ve just consumed 50g of sugar. Further, we are told that a high-fat diet damages the BBB. So how was this worked out?
In this study, researchers gave rabbits 3 mg caffeine each day – the equivalent of a daily cup of coffee for an average-sized person. The rabbits were fed a cholesterol-enriched diet during this time. After 12 weeks a number of laboratory tests showed that the BBB was significantly more intact in rabbits receiving a daily dose of caffeine.
Oh NOW I see. This isn’t about high-fat. It’s about cholesterol.
Hey why is my pet bunny eating cholesterol when he’s a herbivore?!? Isn’t it possible this means the results are totally irrelevant as far as omnivorous humans are concerned?
And if cholesterol is the evil here… what does it have to do with my doughnut? Are they starting to make those with lard again? Last I checked doughnuts were full of vegetable oil and hence “cholesterol free.”
Maybe they mean THIS donut…
The Lady’s Brunch Burger – yes it is really called that
OK my bad. Some donuts, do have cholesterol (must be the eggs). So, you may want to choose, say, a Boston Kreme as your healthy cholesterol-free choice.
But I digress…
If I’m not mistaken, it was feeding cholesterol to rabbits which started this whole scare about dietary cholesterol in the first place. I admit I’m surprised that they keep feeding cholesterol to these animals given that the relevance of the research will always be disputed.
Personally I’m waiting for the study where they feed bamboo to lions and conclude that a high-fibre diet is bad for you.
So what’s the conclusion of bunnies on coffee and donuts?
High levels of cholesterol are a risk factor for Alzheimer’s disease, perhaps by compromising the protective nature of the blood-brain barrier. For the first time we have shown that chronic ingestion of caffeine protects the BBB from cholesterol-induced leakage.
A risk-factor or correlated?
This seems like one more dubious study hijacked to support the existing gospel on the evils of cholesterol and fat consumption. And the icing on the cake is sloppy presentation confusing high-fat with elevated dietary cholesterol.
Henceforth I propose that all such research should be presented to the killer rabbit before publication.
Monty Python and the Holy Grail. The Vorpal Bunny lays waste to the unworthy.
