Are there any positive effects of caffeine?
Effects on the Body:
* Hormones- You can feel the effects of caffeine in your system within a few minutes of ingesting it, and it stays on your system for many hours-it has a half-life of four to six hours in your body. While in your body, caffeine affects the following hormones: * Adenosine- Can inhibit absorption of adenosine, which calms the body, which can make you feel alert in the short run, but can cause sleep problems later. (More on this below.) * Adrenaline- Caffeine injects adrenaline into your system, giving you a temporary boost, but possibly making you fatigued and depressed later. If you take more caffeine to counteract these effects, you end up spending the day in an agitated state, and might find yourself jumpy and edgy by night. * Cortisol- Can increase the body's levels of cortisol, the "stress hormone", which can lead to other health consequences ranging from weight gain and moodiness to heart disease and diabetes. * Dopamine-Caffeine increases dopamine levels in your system, acting in a way similar to amphetamines, which can make you feel good after taking it, but after it wears off you can feel 'low'. It can also lead to a physical dependence because of dopamine manipulation. These changes caffeine makes in your physiology can have both positive and negative consequences: * Sleep Caffeine can affect your sleep by keeping you awake longer, thereby shortening the amount of sleep you get, and giving you less time in the restorative stages of sleep, which takes a toll on your level of alertness the next day and overall health. Interestingly, though, caffeine doesn't affect the stages of sleep the way other stimulants do, so it's a better choice than speed or other 'uppers' to use if you need to stay awake. * Weight Many experts believe that increased levels of cortisol lead to stronger cravings for fat and carbohydrates, and cause the body to store fat in the abdomen. (Abdominal fat carries with it greater health risks than other types of fat.) Also, if increased cortisol levels lead to stronger cravings for caffeine-laden foods, the body goes into a cycle that leads only to worse health. The good news, though, is that caffeine can speed up metabolism. Also, it can help the body break down fat about 30% more efficiently if consumed prior to exercise. (You must be exercising to get this benefit, though.) Additionally, caffeine can keep blood sugar levels elevated, leaving you feeling less hungry. * Exercise If caffeine elevates levels of cortisol and other hormones for a temporary boost, after caffeine wears off, the body can feel fatigued and feelings of mild to moderate depression can set in. This can make physical activity more difficult. On the positive side, caffeine has been found to enhance physical performance and endurance if it isn't overused. This, combined with its effect of fat burning during exercise, can actually enhance workouts and enable you to get in better shape if you take it at the right time.
Beer does not naturally contain caffeine unless it's brewed with caffeine-containing ingredients.
Does caffeine reduce headaches?
Yes. as your blood sugar level rises, the body begins to produce insulin to bring it back to normal levels. If the body makes too much insulin, you "crash" and your blood sugar level drops too low for a time. During that time you will feel sluggish, irratable and have a massive headache. At least I do.
How does caffeine affect metabolism?
The caffeine that is located in coffee can affect or alterate the metabolism.
First, the caffeine accelerates the pulse rate, then it accelerates the metabolism and finally the digestive system (you burn calories faster and digest what you ate faster)
A Perfect example of metabolism is a plant cell.
The plant cell needs energy so that it can convert the sun´s energy into energy useful for the cell and if this part of the cell die (this part of the cell is called chloroplast)
the cell can not produce energy and the metabolism stops working and after all the cell dies.
What is the legal status for caffeine?
Like most legal things, nobody has thought, or had the time, to make it illegal. It is such a part of modern life that even if it were found to be dangerous, it would be hard to pass a law to ban it.
I would say yes and no because it is a type of drug and it can a variety of effects on your body or system, some good and some bad.
It is a stimulant that affects the brain and the heart for instance. It is an addictive drug and like any drug, in overdose it can cause problems (headache, tremor, etc). In fact it works in the same way cocaine works!
Most people take caffeine daily as it is found in coffee, tea, chocolate and cola drinks.
For the millions who take it in moderation, so far there appear to be no major problems although it depends on how you take it. Taking it daily in tea will clearly have a different effect than taking it as chocolate.
For the heart, coffee raises blood pressure but its effects are temporary, lasting less than an hour.
Many scientific studies have been done on caffeine and on coffee with no major problems uncovered and in fact some benefits. Read more about it at via the link below.
Does green tea ice cream have caffeine?
Check the ingredients. If it's made with tea as an ingredient, it does! I happen to know that Haagen-Dazs' green tea ice cream is made using real green tea, and therefore it does contain caffiene. Some brands might use artificial flavors instead of real tea, and those brands will not have caffeine.
My guess would be that it contains more caffeine per unit of volume than actual green tea (though green tea has less caffeine than black tea), but this is mere speculation.

Is caffeine oraganic or inorganic?
Caffeine is a chemical compound found in a variety of plants. I was tought this by my coolies science teacher. Here is the source:
Caffeine is a bitter, white crystalline xanthine alkaloid that acts as a psychoactive stimulant drug. Caffeine was discovered by a German chemist, Friedrich Ferdinand Runge, in 1819. He coined the term "kaffein", a chemical compound in coffee, which in English became caffeine.[3] Caffeine is also part of the chemical mixtures and insoluble complexes guaranine found in guarana, mateine found in mate, and theine found in tea; all of which contain additional alkaloids such as the cardiac stimulants theophylline and theobromine, and often other chemicals such as polyphenols which can form insoluble complexes with caffeine.[4] by solian.

Why can't mormom's drink caffeine?
6 And, behold, this should be wine, yea, pure wine of the grape of the vine, of your own make.
7 And, again, strong drinks are not for the belly, but for the washing of your bodies.
Answer
Yes, of course we *can* drink alcohol, but as the user above noted, we are commanded not to.
see related link;The Word of Wisdom
Chapter 18
Anyone can drink alcohol, although why is beyond me. People probably lose about 20 or more IQ points when they're drunk. Alcohol was originally meant for external use. If something is meant for external use, you probably shouldn't ingest it.
We can't, and most of us don't, but a few do. I, for one, am HIGHLY against it, even though I'm only 13, but that doesn't make much of a difference.
Members of the Church of Jesus Christ of Latter-day Saints (the "Mormon" church) believe in following the "Word of Wisdom", which is a health code that was revealed from God to Joseph Smith. This health code prohibits the consumption of alcohol, and specifically states that alcohol is meant for cleaning purposes.
One must avoid alcohol to qualify for baptism and to qualify to hold leadership or teaching positions in the Church.

Does decaf mean zero caffeine?
Just like decaf coffee, decaf tea does contain a small residual amount of caffeine. The caffeine content will depend on the company producing tea and the process they use, as well as on the original tea's caffeine content. Apparently the High Pressure Carbon Dioxide Process developed in Europe produces the best decaf tea as it removes most of the caffeine, does not leave any residual carbon dioxide and extracts less of the flavor. However, no decaffeination process is perfect, and all decaf tea loses some flavor.
People who want a truly caffeine-free drink that resembles tea will need to drink naturally caffeine-free herbal teas.
any soda if caffinated has to list caffeine as an ingrediant. to the best of my knowledge (not being able to ingest any stimulants due to a bad heart) all gingerale is caffeine free. check your ingredients if your not sure!
Does camomile tea have caffeine?
No, camomile tea does not contain caffeine, but that does not mean that some brand manufacturers will not add a bunch of ingredients that will make the overall product contain caffeine. You will have to check the brand/labels of the product before you can be sure it is caffeine free.
If you grow you own, it will be free of caffeine.
How do you break down caffeine?
There are many different methods to remove the caffine. one way is below, it is a long process and not easy. It would be much easier to just buy decaf at your local market.
In the direct method the coffee beans are first steamed for 30 minutes and then repeatedly rinsed with either methylene chloride or ethyl acetate for about 10 hours. The solvent is then drained away and the beans steamed for an additional 10 hours to remove any residual solvent. Sometimes coffees decaffeinated using ethyl acetate are referred to as naturally processed because ethyl acetate can be derived from various fruits or vegetables. However for the purpose of decaffeination it is not generally possible to create such a large quantity of ethyl acetate, thus the chemical is synthetically derived.
