Far From Free I'm sure you've seen the phrase "caffeine-free" on product packaging, as well as the phrase "no caffeine." So…do those two phrases mean the same thing? They should, but they absolutely do not. Far from it. Caffeine drives me up a wall. Literally. So it's in everyone's best interest if I avoid even a mild caffeine jolt. But I do love a good cuppa joe. And I've been under the impression that decaf is about 97% caffeine free. So every now and then I'll indulge in a cup of decaf from my local Starbucks, confident I'm only getting a trace of caffeine. Little did I know I was flirting with disaster. Consumer Reports (CR) sent out a team of secret shoppers to purchase small cups of coffee (10-12 ounces) at six coffee emporiums: Starbucks, Dunkin' Donuts, Seattle's Best, 7-11, McDonald's, and Burger King. The different javas were analyzed in the CR lab, producing these results: - More than half of the decafs contained less than 5 milligrams of caffeine (the typical small cup of coffee contains about 100 mgs of caffeine, compared to about 30 mgs in a can of Coke)
- The highest level of caffeine in a small decaf was found in one of the Dunkin' Donuts samples: 32 mgs!
- One of the Seattle's Best samples came in second with 29 mgs, followed by a Starbucks sample, weighing in at just over 20 mgs
- The samples that were consistently lowest in caffeine came from McDonald's - each sample contained less than 5 mgs
Here's the result I found most surprising: Caffeine levels varied wildly in both decaf AND caffeinated samples. In the non-decaf coffees, caffeine levels ranged from 58 mgs to 281 mgs! Any 12-ounce cup of coffee that contains more than 200 mgs of caffeine pretty much qualifies as rocket fuel. When it comes to caffeine surprises, Consumer Reports has been on the job for years. Back in 2003, CR ran a feature titled "Test Your Caffeine IQ." I'll dispense with the test and get right to the stimulating stats: - A 1.4-ounce bar of dark chocolate contains nearly 30 mgs of caffeine
- The same amount of milk chocolate may contain as much as 10 mgs
- Dannon coffee flavored yogurt (6-ounce) contains about the same amount of caffeine as a 12-ounce can of Coke
- Decaf coffee typically contains 2-4 mg of caffeine per 8-ounce serving
Obviously, that last stat was just a tad off the mark - updated by the more current CR caffeine report. The 2003 quiz also noted that some bottled waters contain caffeine - the ones enhanced with vitamins, herbs, and other "energy" components. But you'd never know that by reading bottled water nutrition panels because the FDA doesn't require any products to list caffeine content. So what's a consumer to do? You can visit energyfiend.com In the e-Alert "Clear and Present Danger" (1/9/07), I told you about "The Limits" - an Energy Fiend feature that helps you calculate how much coffee it might take to actually kill you - good information if you're ever locked up overnight in a Starbucks. In addition to the dark humor, Energy Fiend provides databases that list caffeine levels in food and beverages and the sugar content in more than 200 beverages. But if "decaf" isn't in your vocabulary and you can't get through the day without loading up on caffeine by the bucketful, then Energy Fiend will quickly direct you to such super- caffeinated beverages as Wired X344, with 344 mgs of caffeine per 16 ounces.
