Commonly Used Caffeine-Containing Plants
The most commonly used caffeine-containing plants are coffee, tea, and to a lesser extent cacao.
First off, coffee and tea aren't plants. Second, I don't see anything related to this sentence in the citation, but I can barely read the citation so yeah. I can't think of any way to fix this without messing up the flow of the paragraph, so I'll leave it here.Ziiv (talk) 02:03, 1 July 2009 (UTC)
Caffine and Stunted growth. Main article inaccuracy...
- Regarding the mistaken conclusions of Nutritionist Joy Bauer cited in the main article.
- Caffine intake stunts the development of long bones. This development has nothing to do with osteoporosis, which is caused by a decrease in density of bone tissue. - Caffine intake slows osteogenesis, conducted by osteoblasts, at the epiphyseal plates of the long bones thereby retarding their growth. The long bones begin growth at conception and continue to grow (on average) into the early to mid twenties. The consumption of caffine durring this growth period will stunt the bones growth by reducing the amount of new bone created at the epiphyseal plate. There is little in the way of long term scientific study since the inhibitory effects can only be measured after the fact. Stated simply, caffine slows bone growth along the long axis. The diminished action at the epiphyseal plate may not cause osteoporosis, but less growth means that the long bone will not form to its full potential. —Preceding unsigned comment added by 24.176.175.218 (talk) 03:53, 6 July 2009 (UTC)A case of list cancer
The list of caffeinated products has been growing steadily, as such lists tend to do. I wonder if anything can be done to impose some sort of discipline on it? Looie496 (talk) 21:12, 7 July 2009 (UTC)
References
Please update the references, an article on the new york times should not be referenced as evidence that caffeinated beverages don't cause dehydration. This is just unacceptable.
Capacity, capability, and perception
There's an edit war going on as to whether C increases capacity for labor, or just increases the amount you can do before you feel tired without increasing the actual capacity. That's a really interesting question. Of course in order to make the article specific about that, we need reliable sources on it. So in meantime, what we need to do is move the article towards language that states only what we have evidence for, and add as little as possible interpretation on top of the facts. The facts (that we, the editors know about from reliable sources) are the experimental results listed below the passage in question.
The new language about perception was very specific about what leads to the increased performance observed. I don't think we know that, so we certainly shouldn't say that. The old language, "capacity," was a little more vague. I didn't find a precise definition for capacity in this context, so it's open to interpretation, just like the data are. That seems fine to me, but I tried to do a little better, but substituting "capability." I don't think that's a whole lot better, and I encourage others to find wording that might more specifically mean what people are able to do in practice, as opposed to what they might hypothetically be able to do before they collapsed. That could include finding a better word, or writing that idea out in more detail. That's all we can do without more information from reliable sources.
I also encourage finding reliable sources that might enable us to put a more detailed explanation of the experimental observations in. But I think that a detailed explanation without a source should be reverted. Ccrrccrr (talk) 02:16, 2 October 2009 (UTC)
Oops
This wiki is kind of a mess. Stimulant? In a way. My son has ADHD and after reading texts on alternative treatments (versus prescribed amphetamines like ritalin), which recommended caffeine, we tried coffee (Starbucks) which calmed him down although a second cup put him to sleep. I spoke with his High School Principal who told me of an ADHD student who passed out after two esspressos and had to be carried home. I've known a dozen adults, not on medication, who get sleepy after drinking coffee. The mechanism that caffeine binds and stimulates ATP Cyclase (not neurotransmitter specific), bound to the neuron interior membrane and activated by a neurotransmitter specific protein bound to the exterior of the neural membrane.Hence, activity of all neurotransmitters is increased: GABA, Cholinergic, Nitric Oxide, etc.
'Caffeine resembles strychnine' and 'Caffeine resembles Adenosine' are both rediculous statements with no basis in chemistry. I could get behind alternate activation sites on the receptors like opiates and endorphins or tetrahydrocannabinol and anandamides. Next I'll hear that Barack Obama and Margaret Thatcher look alike?
Nobody noted that caffeine sublimes and that much of the commercially available caffeine comes from the roasting process. Esspresso roasts acually have less caffeine, but oxidation of caffeic acid and tannins create other (quinone) stimulants and unbinds caffeine from tannins. The pKa link goes to an illegible japanese page. pH of 1% solution is 6.9
Laxative? Rem that cocaine was usually cut with "baby laxative" (mannitol), some people equated the strength of the cocaine by how fast they had to use the bathroom. Loperamide and atropine are muscle relaxants and stop diahrea. More likely the tannins and other stomach irritants in Coffee rather than caffeine are responsible.
FYI although arabica was the shade and robusta was the partial shade type, newest ababicas are gene engineered to full sun. Used to be arabica more acid and robusta higher caffeine, but probably no longer.
Caffeine is a vasopressor, causes high blood pressure. If it is a smooth muscle relaxant it makes sense it is a vasodilator. Caffeine is a repiratory stimulant. Cholinergic effects should be noted .
Even with references there are so many conflicting studies about the "dangers" and "benefits" of caffeine and coffee. I just came accross one of those stupid "chromosome breakage from caffeine" ones that don't have the scientific methodology of a first grade science project. This is re the section on 'caffeine as insecticide' and 'caffeine as plant inhibitor' sections in the Caffeine wiki. This goes with the 'use coffee grounds as mulch' advice in the 'green' section of the newspaper. Turns out it is the acidic tannins that kill plants and those little black flies that suck roots thrive in that coffee soil. My own Fruit Fly lab experiments and this more recent one seem to debunk the lie that caffeine is bad and should be an insecticide. --Shjacks45 (talk) 19:03, 9 November 2009 (UTC)
