( Coffee lovers who have made the choice ...)Decaffeinated Coffee... Not Really!,Health

Coffee lovers who have made the choice to shift gears and use decaffeinated coffee to avoid caffeine in their diet may be in for a shock.// A recent research and data compiled by the University of Florida notes that decaffeinated coffee cannot be virtually free of caffeine.

This month's Journal of Analytical Toxicology. has recorded the findings compiled by the researchers which warn that ,coffee which is one of the most prominent sources of caffeine, a drug warned to be used cautiously by those suffering from systemic disorders like hypertention, renal calculi, or even pregnancy where caffeine is contra-indicated, may not be free from caffeine even when "decaffeinated".

"If someone drinks five to 10 cups of decaffeinated coffee, the dose of caffeine could easily reach the level present in a cup or two of caffeinated coffee," said co-author Bruce Goldberger, Ph.D., a professor and director of UF's William R. Maples Center for Forensic Medicine. "This could be a concern for people who are advised to cut their caffeine intake, such as those with kidney disease or anxiety disorders."

Despite caffeine's widespread use, most medical texts have no guidelines for intake, Goldberger said, but even low doses might adversely affect some people. So UF researchers set out to conduct a two-phase study designed to gauge just how much caffeine is likely to turn up in decaffeinated coffees.

First they purchased 10 16-ounce decaffeinated drip-brewed coffee beverages from nine national chains or local coffee houses and tested them for caffeine content. Caffeine was isolated from the coffee samples and measured by gas chromatography. Every serving but one - instant decaffeinated Folgers Coffee Crystals - contained caffeine, ranging from 8.6 milligrams to 13.9 milligrams.

In comparison, an 8-ounce cup of drip-brewed coffee typically contains 85 milligrams of caffeine.

In the study's second phase, scientists analyzed 12 s
