Daily Caffeine Protects Your Brain

Chroniton writes "The BBC has a story that many Slashdot geeks will be happy to hear: the caffeine from a cup of coffee a day can help prevent Dementia, by blocking the damage of cholesterol. (At least in rabbits) This is in addition to the already-known protection against Alzheimer's Disease. More research is needed to test the effect on humans."

Just make up your fucking minds already, every other week coffee is bad, then good, then bad again.

like it's going to stop anyone drinking it anyway...

Old news flash: most stuff is okay as long as you enjoy it in moderation. If your coffee percolater feeds directly into an IV line then you probably aren't doing your body any good, but one or 2 cups a day and she'll be 'right.

most cholesterol is produced in you body and has little to do with what you eat e.g. some people can eat stake all day and be fine other can eat nothing but lattice and have a cholesterol problem.

Studies on eggs have show that they make no difference and infact a bit more exercise would help a world more than changing you diet.

It's the media. They take a single study and purport it to be some kind of fact. Science doesn't work that way. Science only considers something 'known' when independent study after independent study shows the same thing to be true, and no studies which may have been contradictory have been shown to contradict the findings.

These things take time. Looking at one study alone can be interesting, but it's stupid to take that study's findings as gospel truth.

Perhaps then Alzheimer's is caused by cholesterol damage? You know, if it walks like a duck and quacks like a duck, then... what was I about to say? Ah, yes, then, perhaps eating too much duck meat is bad for your cholesterol if you are a rabbit?

Who ARE You ?!?

It also seems to be the case that the less applicable your study, the more coverage you get. It's running joke now in epidemiology that you get more impact and coverage by showing a potential mechanism in 10 rabbits than you do by demostrating a genuine preventive effect in a population study of 100000 people.

You are entirely correct, sir. If you eat pointy sticks all day, there's no way you will be getting excess cholesterol, whereas eating pastries all day can't be good for you.

This is so unfortunately true. Health fads are all about misinterpretation of the available data, and incomplete data for that matter. Every time there's some news item about the supposed health benefits of something, some idiot takes it to an extreme. Shortly thereafter conflicting data is released and suddenly everything we thought we knew was wrong. Eggs used to be heathy, then they were poisonous, now they're healthy again.

Nobody is going to live forever because of some nutritional change. If you eat a wide variety of fresh unprocessed foods you'll do fine. Everything in moderation.

Re:god damn it

[somersault]

Not yet - reduce the daily dosage steadily every 3 days - half a scoop of grounds per day should be manageable - until you're down at about 2 scoops per day. Then comes the tricky part. You should be able to work your way back to mugs, but be careful not to bite down on the rim. Your body will also be used to a steady stream of caffeine, so keep it coming regularly at first - say a cup every half hour, otherwise you get those monkey on your back cravings and may find yourself climbing up the side of your building naked while listening to the 2001 OST and flinging faeces at people. That only happened one time though; I've now learned to be more careful when easing off after a deadline.

Good luck.

It is true that most cholesterol is produced in the body, but that does not mean that dietary cholesterol is not important. First of all, the typical American diet is heavily weighted in favor of saturated fats. Saturated fats stimulate the body to release more cholesterol into the blood, of the LDL ("bad") variety. So while eating a food high in cholesterol may not contribute directly to your cholesterol level, typically those high cholesterol containing foods also contain large amounts of saturated fats, and those saturated fats will contribute to your cholesterol level. Steak is definitely a rich source of saturated fat, so you should moderate your intake.

Which brings up another point: some people are more susceptible to the effects of high blood cholesterol than others. Unless you know for sure which group you're in (and who really does?), don't you think you should use a little discretion in choosing your diet? Furthermore, by getting your daily fat intake from vegetable sources, you're doing yourself additional favors, because you are probably also increasing your intake of dietary fiber, bioavailable vitamins, minerals, and anti-oxidants (which also has an LDL-lowering effect).

You're right about the exercise bit, though. If people spent half as much energy worrying about their exercise regimen as they do fretting about whether they should eat carbs or not, people in general would be a lot healthier. Trust me, once you reach a certain level of daily exertion, your body will burn just about anything efficiently.

Interestingly enough, drinking coffee can cause higher cholesterol, even though it contains none. French press coffee contains cafestol which seems to boost the body's production of cholesterol (or inhibit the degredation, it's not clear). There's a measurable dose dependent effect, so as much as it pains me I've quit drinking French press coffee in favor of drip, a paper filter seems to bind the cafestol and remove it.

Who wood eat nothing but stakes or lattice anyway?

They own Java, though I didn't know that contained caffeine.

How odd

[Anonymous Coward]

That's funny, because the more cups of coffee I drink, the crazier everyone else says I am. I must just be the only sane one, sitting here rearranging my pencils after my eighth cup this morning.

Re:How odd

[Kamineko]

Here's a challenge. Try to arrange six pencils of the same length so that they're all touching every other pencil.

Without snapping or disintergrating them.

How could they possibly know this?

[LaughingCoder]

Surely the number of rabbits who enjoy a daily cup of coffee is such a small population as to be statistically insignificant.

Re:How could they possibly know this?

[loftwyr]

Yes, but the number of rabbits with dementia is huge based on my cartoon viewing. So at least they have a good sized population to test it with.

Perhaps we should start testing with ducks next. I've never seen a non-demented duck.

Re:How could they possibly know this?

[solraith]

You're dethpicable.

Demented rabbits?

[unstable23]

How do they know?

As anyone who's ever owned a rabbit will tell you, they're pretty demented to begin with.

And a rabbit on caffeine is just plain scary.

Re:Forgot the difference

[SimonGhent]

Alzheimer's is a specific disease.

Dementia is just a general term for (usually) old-age brain rot.

Re:Hmm yes

[Doc Ri]

A glass of wine is good, too. A bottle? Perhaps not.

This is why I own glasses that can hold the entire content of a bottle.

Re:Yeah, yeah...

[Sobrique]

It is entirely possible that a glass of wine can both prevent altzheimers, and cause high blood pressure. Just because some of the effects of something are beneficial, and some are negative doesn't mean that one precludes the other.

Most medicines, after all, include side effects.

A single factor of many

[athloi]

Coffee helps protect against dementia.

But, it leeches calcium from your bones.

Still, it avoids erectile dysfunction.

However, it destroys a good night's sleep.

Yet it can keep you thin.

But, it might make you take up smoking...

And so on, forever and ever, until people admit that even scientists recognize the world is more complicated than a single factor at a time.

Re:Caffeine or coffee?

[aadvancedGIR]

Shut up and buy what the study sponsor wants to sell you.

Re:Hmm yes

[CastrTroy]

Does it annoy anybody else that a cup of coffee is a standard in and of itself? A 12 cup coffee maker only makes 12, 5 oz. cups. Since when is 5 oz. equal to a cup? A measuring cup is 8 oz. the and cup that most people use for coffee is probably around 10-16 oz. So, in this study, do they mean the 5 oz. cup, the 8 oz. cup, or the 16 oz. cup?

Recommended daily allowance?

[Samedi1971]

I thought my rabbit was going to be perfectly healthy on a diet of hay and fresh greens. How many cups of coffee should he be drinking daily to be safe?

Adopt a rabbit!

Re:exercise

[Mister Whirly]

"There are lower-impact sports, such as cycling"

Ah, but the trade-off there is that you have to wear those fruity little pants. No thanks, I'll risk the knee injuries.

Re:exercise

[TigerNut]

Runner's World says (and an increasing number of over-60 runners bears this out) that Running Is Good For You. Good for your bones, because your bone density doesn't reduce as much. Good for your muscles, because if you don't use them, you lose them. Good for your joints, because the impact of running (in moderation) keeps things lubricated. And also good for your brain because exercise releases endorphins and other hormones that keep things in balance.

The problem is that folks generally have this view that they could never run a marathon, so why run at all (extend that to any given sport)? The answer is to recognize that pretty much anyone can improve their fitness from where it's at today, and it's amazing to see how quickly the body can become accustomed to an increased level of activity, so long as the increase is kept within reasonable bounds. Being more fit makes just about every daily activity more fun and less stressful, and it amazes me that in so many of the 'self-help' TV shows that are on the tube these days, they turn to surgery for what is really just a lack-of-exercise problem.
