The Caffeine Debate
—Still Brewing Strong
Caffeine is a mild stimulant that is present in many plants, the most popular of which are coffee beans,tea leaves, and cocoa nuts. This, of course, is howcaffeine sneaks into our daily diet, from our morningcup of Starbuck’s to that late night munch on aHershey bar. Caffeine is also artificially added toother products, including a number of beverages.
A typical drip-brewed cup of coffee may contain around 100 milligrams of caffeine, and that’s just asix-ounce cup. What about tea? Often hailed as thecompletely safe alternative to coffee, a six-ounce cupof tea contains 70 milligrams of caffeine, making itsomewhat less threatening, but clearly not as inno-cent as most assume. In any event, more than half ofus in this country take in more than 300 milligramsof caffeine each day.

As a stimulant, caffeine doescause a small, short-lived rise in blood pressure,which is most noticeable to those who have not hadcaffeine for a period of time.

Granted, there are theheadaches that some suffer when they try tocut down or eliminate caffeine from theirdiet. This symptom, however, is clearly in adifferent league from the withdrawal pains ofa cocaine or heroin addict.
Caffeine has been the subject of thousands of research projects, making it one of themost heavily studied commodities of theworld. But the results of these studies—andhow to interpret those results—are hardlyconclusive. Some experts claim that there isno firm data to prove that caffeine is a riskfactor in such problems as breast cancer,colon cancer, bladder cancer, pancreatic can-cer, ulcers, or miscarriage.
