Do
decaffinated teas still have caffeine and if they do what
is a healthy percentage of caffiene? Which is healthier
green or black tea?
Decaffeinated
teas and coffees still have small amounts of caffeine. Caffeine
occurs naturally in coffee and cocoa beans, kola nuts and
tealeaves. It is a key ingredient of cola drinks, chocolate,
many non-prescription medications and even dietary and sport
supplements. Caffeine acts as a mild central nervous system
stimulant so it provides an initial boost of energy, keeps
us alert and prevents fatigue. Our main sources of it are
coffee, tea and soft drinks.
A moderate amount of caffeine
per day, approximately 300 milligrams, is relatively harmless
for most people. Excessive caffeine can give you the shakes,
lead to anxiety, upset your tummy, and keep you from sleeping.
A recent study (Pediatrics, 2003) suggests that drinking
too many caffeinated soft drinks might be preventing some
adolescents from getting a good night’s sleep. This
is a good enough reason for some parents to insist that
their children’s schools should not have soft drink
vending machines.
Some individuals may be sensitive
to the effects of caffeine at very small doses, and pregnancy
and aging can affect this sensitivity. So these people should
be careful with their intake. Caffeine is an ingredient
in more than 1000 over-the-counter drugs, as well as prescription
drugs. Read product labels and ask your pharmacist if you
are concerned about caffeine intake.
