Daily Caffeine Protects Your Brain

Posted by samzenpus on Thu Apr 03, 2008 06:52 AM
from the it's-what-brains-crave dept.
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."

[+] Coffee Can Reduce the Risk of Alzheimer's 242 comments
Amenacier writes "Recent studies by Finnish and Swedish researchers have shown that drinking moderate amounts of coffee can reduce the risk of Alzheimer's disease in people. The reason for this is as yet unknown, although it has been hypothesized that the high levels of antioxidants found in coffee may play a role in preventing dementia and Alzheimer's. Alternatively, some studies have shown that coffee can protect nerves, which may help prevent Alzheimer's. Other studies have shown that coffee may also help to protect against diabetes, another disease which has been shown to have links to Alzheimer's disease. However, researchers warn against drinking too much coffee, as 3 cups or more may cause hallucinations."

                Runner's World [runnersworld.com] 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.

            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 [wikipedia.org] 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.

          Won't work. Most of the cholesterol in your body is PRODUCED by your body, not obtained from ingested food.

          Indeed there's some controversy in medical-science circles currently over to what degree food-cholesterol (like in eggs) influence blood-cholesterol at all.

          Regardless of how that particular debate ends though, you'll have cholesterol in your blood even if you eat -zero- of it.

          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.

        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.

      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.
