I’ve read that it can contribute to birth defects and other problems by slightly affecting your DNA overtime.

Meh, after caffeine stopped working I switched to Ginseng. Now I just alternate between the two uppers when one stops working.

Receptors are molecules (proteins) not cells…. the whole whole article remains suspect as long as the basic science remains so fundamentally wrong! Actually the whole thing esp the you vs kids hypothesis is so crap I wont touch it further.

I stopped drinking caffeine only a week ago, and already I’ve noticed that I’m no longer an insomniac and that I have a much more natural rhythm to my day. By the way, this article states that chocolate provides caffeine, but chocolate actually contains theobromine, which admittedly is extremely similar to caffeine, but it isn’t caffeine… just thought I’d point out that common misconception [http://www.xocoatl.org/caffeine.htm].

This article is so full of flaws. Besides the mentioned corrections in comments, it is important to note that caffeine works on different levels besides the described adenosine blocking. It increases adrenaline and serotonine levels too, resulting in quick energy release and positive mood change.

Forgot the kidney stones. Excess caffeine, as I have so recently discovered can cause kidney stones.

that’s like saying people are molecules (atoms). which is true. but they’re also people.
neurons in your brain have receptors which are made of biomacromolecules (proteins) but theyr’e also.. damn i’m out of things lying to my brain to tell me to keep thinking

Rob Goretksy says: While I enjoy (need) a cup of office coffee to start the day in the morning, I stay away from Starbucks and Dunkin Donuts’ due to the insane amounts of caffeine those coffees contain. One tall Starbucks coffee has as much caffeine as 4 or 5 cans of cola, and about triple your standard drip coffee. Getting used to this high an amount just can’t be healthy.. Everything in moderation! Comment by Rob Goretsky of Hoboken, NJ

Caffeine also has another important effect not discussed here:
Acetylcholine is a neurotransmitter. When excreted into your brain, it causes nerve impulses. Acetylcholine esterase is an enzyme that normally degrades acetylcholine and prevents the brain from maintaining an excited state for unnecessarily long times. Caffeine messes this all up by inhibiting the action of acetylcholine esterase. Thus, your neurons just keep on firing.

This article is poorly researched and poorly sourced. There is, in fact, no caffeine in chocolate. Thie primary source of intake for children (0-12) and adolescents (12-18) is consumption of “softdrinks” which are laced with caffeine.

Nice article very informative, I changed to guarana to keep me going, longer lasting then caffeine and seems to do the trick for me.

big corporations (like starbucks) know that people are prone to addiction, and they’re not helping… i say it’s all a conspiracy… and everybody is buying into it.
although i do love a cup of coffee in the morning, i also practice self control. as long as caffeine (or any substance, really) is taken in moderation, it won’t really be detrimental to your health. be smart.

I just had to make a few comments about this caffeine thing.
I’am 65 years old and in better shape than most people my age or younger.
I started drinking coffee(black) when I was in the seventh grade. That was my breakfast before going to school. At that time I had about 2-3 cups, then would have 2-3 cups in the evening. This escalated to my daily average of about 12 or more cups per day, which I have consumed for the last 25 or so years, along with my pack or so of cigarettes daily.
I’am not nervous and jerky and I get my normal 6 hours of sleep a day.
All of this talk about what caffeine does to you,(in my opinion)is just bull.
I believe it all depends on a persons metabolism. That is, like your DNA, everybodys metabolism is different.
So for all of you people that can’t handle it, I will have my first cigarette and my first cup of coffee tommorrow morning, thinking of you. Cheers.
