Many people who have medical conditions like hypertension and heart arrhythmia as well as those taking certain medications would be better off without the caffeine so they turn to decaffeinated coffee.

What they don’t know is that decaf coffee contains caffeine too and that in large doses could actually reach the levels present in a cup or two of caffeinated coffee.

Some people may experience adverse effects even from small amounts of caffeine.

Some of the recent studies have been conducted to see how much caffeine is likely to be found in popular decaffeinated coffees. The cups of decaf coffees were purchased from different coffee shops and restaurants. To their surprise, 9 out of 10 cups were found to contain anywhere between 8.6 milligrams to 13.9 milligrams. The amount of caffeine found in decaf cups represents one tenth of the caffeine found in regular coffee.

Researchers report that even the small amounts of caffeine found in decaf coffee is enough to cause dependence. They are also trying to warn the public that decaf is not the same as caffeine-free and that those people who have to watch their caffeine intake should be very careful about what they are getting.
