Caffeine, I found out, is a naturally occuring drug that is found in coffee, tea, and drugs. Colas have caffeine added to give these drinks a little "zip." Decaffeinated coffee have some of the caffeine removed; they still contain at least 2%. The first decaffeinated coffee was Sanka, a contraction of the French term sans caffeine. A cup of brewed coffee contains up to 180 mgs of caffeine. Instant coffee (which I drink at home) contains roughly two-thirds as much, and teas even less. Noncola drinks such as Mountain Dew contains 53 mgs.
Did you know caffeine is used in aspirins and acetaminophens to enhance their painkilling abilities? When ingested, caffeine's full effects are felt within fifteen to forty-five minutes and leaves the blood stream after five or six hours. The British have it right. The best time of day to have a cup of coffee or tea is at the traditional "tea time." Your body's internal clock is peaking around 4:00 p. m.
Recent medical research has touted some of the health benefits of caffeine. I won't go into the details; you can go to this site if interested: http://www.medicalnewstoday.com/articles/270202.php Coffee may be protective against type 2 diabetes. Coffee may help control movement in people suffering from Parkinson's; coffee consumption can lower the incidence of cirrhosis of the liver; and drinking coffee in moderation protects against heart failure.
Now, excuse me. It's time for my nightcap...coffee, of course.
