Their subjects were 50 men who consumed similar amounts of coffee or water while researchers measured their urine output.

In a study published this year, however, researchers in England looked specifically at caffeinated coffee. Their study, which followed subjects for 11 days of controlled caffeine consumption, came to this conclusion: вЂњThese findings question the widely accepted notion that caffeine consumption acts chronically as a diuretic.вЂќД«ecause caffeine has been considered a diuretic, people have worried that drinking coffee can contribute to dehydration. But University of Connecticut researchers studied the effects of caffeine on healthy, active men in 2005 and found no indication of such an effect. But the forms are distinguishable by laboratory analysis.ДЄnyone who has slammed a large cup of coffee and then been stuck in a traffic jam may conclude that caffeine is a diuretic. Whatever the origin, the chemical is the same, and it has the same physiological effects. The caffeine is not extracted from natural plant products such as coffee or tea, but assembled from chemical precursors including urea and chloroacetic acid. Some caffeine is still produced this way, and some as a byproduct of coffee decaffeination.Д«ut most of the powdered caffeine we now use is synthesized in pharmaceutical plants, primarily in China but also in Germany and India. In the early days, it was produced by domestic chemical companies such as Monsanto, which began extracting caffeine from waste tea leaves in 1905 to supply Coca-Cola.

(When the practice began, Coke and Pepsi were marketed as tonics for fatigue, and caffeine gave them their pep.) The United States now imports more than 15 million pounds of powdered caffeine annually most for use in soft drinks. Most pure caffeine is derived from plants like coffee and tea.ДЇor more than 100 years, bottlers have been blending the pure, powdered form of the drug into soft drinks. That is a lot, but an equal-size serving of Starbucks coffee would have twice as much.Д«ottom line: If you want a strong caffeine jolt, stick to the joe.ДЈ. A 22-ounce bottle of NOS, an energy drink bottled by Coca-Cola, does contain 220 milligrams of caffeine. Few energy drinks approach the latter level, which equals four Red Bulls. Starbucks claims approximately 260 milligrams of caffeine per 12-ounce cup of drip-brewed coffee (вЂњtallвЂќ) and 330 milligrams per 16-ounce cup (вЂњgrandeвЂќ). A can of Monster contains 184 milligrams.Д«ut even these larger energy drinks donвЂ™t approach the caffeine levels of Starbucks coffee, which tends to have higher caffeine concentrations than DunkinвЂ™ Donuts coffee, for example. One analysis found an average of 188 milligrams of caffeine per 16-ounce cup of coffee. At this serving size, the drinks begin to approach the caffeine levels of coffee. ThatвЂ™s equivalent to a mere four ounces of drip-brewed coffee from Starbucks.Д¬ans of the super-size energy drinks such as Monster and Rockstar are twice the size of the little Red Bulls, with roughly twice the caffeine. The original 8.4-ounce can has 80 milligrams of caffeine. Energy drinks have more caffeine than coffee. ThatвЂ™s something to bear in mind the next time you hear phrases like вЂњIn our hyper-caffeinated societyВ .вЂ‰.вЂ‰.В вЂќДў. But, with their lower caffeine content, soft drinks have not replaced the caffeine weвЂ™ve dropped from our diets by drinking less coffee. Two recent surveys, one by the Food and Drug Administration and one for an industry-backed research group, show that coffee accounts for two-thirds of the caffeine in the American diet.ДЄs coffee drinking fell, soft drink consumption surged, rising from 11 gallons per person annually in 1947 to 51 gallons in 2005. And despite the abundance of new ways to consume caffeine, we still get most of our caffeine from coffee. From 1946 to 2005, it declined roughly by half, from 46 gallons per person each year to 24 gallons. coffee consumption peaked 65 years ago, then fell dramatically.
