DailyDirt: This Is Your Brain On Caffeine. Any Questions?
from the urls-we-dig-up dept
Making the perfect cup of coffee is an experiment that's been studied for decades -- if not for hundreds of years since coffee was first brewed in the 1300s. It's not an exact science yet, but studies on coffee drinking seem to point to it being mostly beneficial. Here are just a few interesting links for coffee lovers out there.- According to one study, you're probably drinking too much coffee if you consume more than 28 cups per week. But if you're over 55, it apparently doesn't matter much to your health if you're drinking more than that amount of coffee. So if you're younger than 55 and drinking more than 4 cups every day, you just need to live a little longer and you can drink as much as you want. In fact, some other studies say coffee can lower the risk of premature death. [url]
- If you think that decaffeinated coffee is free of caffeine, think again. Decaf just has lower amounts of caffeine -- 3 to 15 milligrams per cup versus 85 milligrams (or more) for regular coffee. Those milligrams can add up if you're drinking a lot of decaf coffee. [url]
- Conventional wisdom says that pregnant women shouldn't drink coffee (or drink alcohol or eat sushi), but maybe the risks of doing so aren't that high? Better safe than sorry, though, right? [url]
- Even though people have been drinking coffee for centuries, the effect of coffee on our health isn't really clear. Caffeine might not be the only active ingredient in coffee, and studies haven't always separated out the smokers who seem to drink a lot of coffee. [url]
Thank you for reading this Techdirt post. With so many things competing for everyone’s attention these days, we really appreciate you giving us your time. We work hard every day to put quality content out there for our community.
Techdirt is one of the few remaining truly independent media outlets. We do not have a giant corporation behind us, and we rely heavily on our community to support us, in an age when advertisers are increasingly uninterested in sponsoring small, independent sites — especially a site like ours that is unwilling to pull punches in its reporting and analysis.
While other websites have resorted to paywalls, registration requirements, and increasingly annoying/intrusive advertising, we have always kept Techdirt open and available to anyone. But in order to continue doing so, we need your support. We offer a variety of ways for our readers to support us, from direct donations to special subscriptions and cool merchandise — and every little bit helps. Thank you.

But all this does is reenforce my decision not to drink coffee.

Are Drugs Bad?
Want a more precise term than “drug”? How about “psychoactive substance”?
Some people don’t like the thought of imbibing drugs for pleasure. A lot of these same people don’t like to see ethanol and nicotine lumped in with other drugs.
Also I’ve seen repeated studies try to find something bad about caffeine—even trying to link it with cancer. So far, none of the charges have stuck.

caffeine factoid...
(ie is MORE 'deadly')
just sayin'...

Re: caffeine factoid...
Here for your entertainment, see the funny named compounds that exist from Arsole to Draculin
http://www.chm.bris.ac.uk/sillymolecules/sillymols.htm
Check with the IUPAC, CAS number, ATC Code, PubChem, DrugBank, ChemSpider, UNII, KEGG, ChEBI or ChEMBL databases
You learn more factoids about the compounds you are looking for.

Re: caffeine factoid...
So LD50 in mice for Caffeine is 192 mg/Kg(when ingested orally) in rats.(Just wait for it.) In humans LD50 is considered 150-200 mg/Kg depending on sensitivities and what not. So we take an average human(180 lbs, convert to Kilograms 180/2.2 = 81.81repeating. Take that number and multily by the mean of the LD50(I say is 175 mg/Kg) = 14.318repeating Grams is the LD50.
For cocaine it is roughly guessimated(All sites never broke past 1.5G so I decided to use this number) to be 1.2-1.5 Grams for a human. So in other words cocaine is a significant figure more lethal than cocaine.
So instead we'll use a different method. We can assume that a ratio of LD50s when compared to in Rats will produce a ratio that should represent the approximate ratio in humans.
Therefore the LD50 of caffeine for rats is 260 mg/Kg(Injected into cavern) and for cocaine it is 92mg/Kg(Injected into cavern.) This produces an approximate ratio of cocaine being 3 times more lethal than caffeine, which is supported above.

Re: Are Drugs Bad?
Could be, it depends on a lot of things, like genetic makeup of the subject exposed to it, mean of exposure(oral, nasal, injected, absorbed, etc), dose, lenght of exposure, production of the substance that may not be entirely pure and may have contaminants(e.g. Ontario Minamata disease, which used the Castner–Kellner process which is a mercury cell that despite recycling the mercury still contaminates the products and by-products of the process.
Now it is a grave threat to humans?
I don't think so, is not like caffeine is produced with dangerous chemicals that can contaminate it, and people have been using it for almost a thousand years without mass dying or severe consequences, different from heavy metals like lead that was used by VIP's in antiguity for cosmectics or mercury that a Chinese imperor drank to be immortal or something and died.
But I am glad that we are almost at the point where sensors for almost everything are just around the corner, than we will be to create huge databases of information to see what is what, if governments don't screw it up, I don't know how they will do it, but I am certain someone somewhere will find a way to use this to screw others and it will be a threat to privacy, then we will need rules to guide us to how we collect and interact with such data, data that we need to keep us safe but that it can also be misused.
But I digress, when I encounter a chemical, I look at what it does, its toxicity, how it is produced and how it could interact with others chemicals, this information is not easy to come by though, I would love to see a public database of all known chemical reactions where I could just type the inCh, SMILE or popular name and see what it happens.
It took me months to realize that gases from burning biomass can be turned into gypsum and other useful substances so that toxic "sulfur" would be transformed into something inert, still this is just the tip of an iceberg.
Imagine using Hydrogen sulfide as a precursor for another substance or substances. That smelly gas can be used to produce elemental sulfur and hydrogen or be transformed into another substance that uses hydrogen and sulfur.
Can you imagine when you can take samples from your air, water and see the substances that are in it, and query a database about possible chem reactions? which can be influenced by temperature, PH, pressure and some other factors, and you can transform "toxic" elements into useful things for yourself?
This is one initiative trying to sense the enviroment we live in.
http://publiclab.org/
That is the time when we transform ourselves as a group from parasites to a symbiotic relationship with our environment I believe.

Of all the ways
True, they're all addicting, but I've never seen anyone held up by a crazed caffeine addict saying:
"Your coffee cup or your life."

Is there really a need to address century-old food consumption habits? Isn't the problem the overindustrialization of food to begin with? I take those studies with a ton of salt, not a grain. Really. Specially when they address food that's been around for ages.

Re:
Which I believe is a bit suicidal, any organism that adapts itself to great amounts of resources may fail in the long run.
So all those illness caused by over consumption of food like diabetes type II are not necessary a bad thing, they are a warning from our biological systems to stop munching so much and those who don't pay attention will die.
I think over production is a symptom of over consumption.
As the old saying goes, the poison is in the quantity.
In this case the quantity you consume.
