The current junior high craze is coffee shops. Although my girls drink only decaffeinated coffees, I'm concerned that even these have caffeine.
Decaffeinated coffee does contain caffeine, but the amount is quite small.
The same 7-ounce cup of regular coffee has about 115 to 175 milligrams, depending on brew strength. Moderate caffeine consumption has not been shown to be harmful to adults or children. While individual sensitivity varies, children appear to be no more susceptible to the effects of caffeine than adults. Studies have shown that moderate amounts of caffeine do not cause hyperactivity, or increase the risk of cancer, osteoporosis, or cardiovascular disease. One real concern is that more nutritious beverages may be ignored by teens who routinely reach for sodas and coffees.
