Is there a big difference between synthetic and natural caffeine? Apparently, synthetic caffeine is much more powerful than the caffeine found naturally in plants. The question is, is synthetic caffeine harmful?
Some fairly ominous-sounding chemicals are used to process synthetic caffeine. Websites are unclear as to whether the ethyl acetate and methylene chloride (and carbon dioxide) used to process urea to manufacture synthetic caffeine remain in the product. Ethyl acetate is used as a flavoring in some foods, though, so perhaps it is not harmful and may remain in synthetic caffeine.
Why does soda have caffeine in it? Caffeine does add to the complex flavors of the various types of caffeinated soda. In fact, the taste of caffeine is bitter and has to be balanced with sugars or sweeteners and other flavors. Caffeine also adds a boost in energy to the drinkers of soda.
But what reason do the manufacturers give for adding caffeine to soda pop?
Some research has suggested that caffeine may stimulate thermogenesis - a scientific name for the way your body generates heat and energy from the calories in your food; but nutrition experts say that this effect probably isn't enough to produce significant weight-loss. Caffeine may also reduce your desire to eat for a brief time, but again, there's no good evidence over the long-term that this effect leads to weight-loss. To date, no conclusive clinical studies have been done to determine the long-term effect of caffeine on weight loss, and the smaller studies that have been done show a lot of variability in the outcomes.
How bad is caffeine withdrawal? People who have a caffeine habit may empathize with a scene of the 1931 production of Frankenstein, in which the mad scientist exults over the animation of his monster, exclaiming “It’s alive! It’s a alive, it’s alive!” I know I get animated in the morning after drinking my first cup of the ichor we call coffee.
Caffeinated products are wildly popular worldwide, used by as much as 90 percent of the adult population. An estimated 80 percent of American adults take caffeine in one product or another, and it’s estimated half of those people are prone to headaches for one reason or another. If you are among the caffeine users who get caffeine withdrawal headaches from coffee, tea or energy drinks, there are a few things you can do to minimize the pain.
The afternoon slump would be OK if you could just lie down for a little nap. But most of us have to earn a living, and management would likely frown on anyone who went home from 2 to 4 p.m. for a siesta.
If a nap is out of the question, how can a worker cope with an urge to sleep after lunch? First, let’s explore the reasons why some people become drowsy after lunch.
Studies of caffeine show that it does not increase the risk of death, but it causes a habit or possibly a dependence that the American Psychiatric Association now lists in its diagnosis manual as a disorder that warrants more study.
Scientists study caffeine and its use by humans a lot, some say more than any other psychoactive substance in the world. Caffeine is the most widely used drug, and more scientists are saying now there should be yet more studies into dependence and other aspects of caffeine consumption.
What is the chemistry of coffee? Caffeine is the most famous chemical compound in coffee, but roasted coffee beans contain more than 1,000 other compounds. Some of these chemicals are noxious but still are not unhealthy because they are present in such low amounts.
You never hear anybody wake up and say, “I need a big dose of putrescine and dimethyl disulfide in my morning cup.”
Preparing for exams and tests in high school and college may be essential to getting an A, entering the university of your dreams or making the grade to go on for a master’s degree. Assuming you’ve studied the subject or subjects thoroughly, what should you do just one before an exam?
If it’s a big mid-term or final, an Advanced Placement or a Graduate Record Exam or other graduate school test, most people have to study the subjects thoroughly during the semester or school year or years. Attempting to learn all the material one hour before the very end is not a good strategy for a final exam or for a placement test.
Caffeine and fasting are controversial in some circles. Is it truly fasting if you have coffee or other liquids during your time of abstaining from eating? Some people say to be a pure fast, one must drink only water and eat nothing. Others maintain that having coffee and/or other liquids is healthier and ensures you don’t become dehydrated.
What is the latest thinking on avoiding coffee before a blood test?
You have a problem. You must fast for 12 hours (overnight) before your blood test, but you have a real dependence on coffee or caffeine. You need that cup of caffeinated energy before you even walk out the door. Otherwise, grogginess, a headache and a general feeling of malaise may set in.
May we suggest that you get up earlier than your usual coffee time and arrive at the laboratory as early as possible?
