Q: “I just finished re-reading your detox diet book. Under the caffeine section you discussed the use of tea as a stimulant, then went on to make a distinction between black and green tea, but not enough for clarity. I drink many cups of green tea per day. Should I be weaning off of that too? And if I go to a decaffeinated green tea, does that reduce the healing properties associated with green tea? Also , does green tea consumption count towards the daily intake of water requirement?”

Caffeine is present in tea leaves and in coffee. Tea also contains two other alkaloids, theobromine and theophylline. These last two relax the smooth muscles where caffeine stimulates the heart and respiratory systems. I have worked with many people who find that the caffeine from both black and green tea do not create the same intense effects as coffee. While this is anecdotal, several clients, including myself, find that coffee produces a jittery, anxious energy, headaches, and a serious caffeine crash.
You can reduce the amount of caffeine found in your tea by steeping it for 30 seconds and discarding this first cup. Most of the caffeine is released in the first 30-60 seconds when it comes to green tea. Make a 2nd cup of less-caffeinated tea with the same bag.
Also, the health promoting aspects of green tea are reduced when the leaves are decaffeinated. According to one study:
“flavanol content varied from 21.2 to 103.2 mg/g for regular teas and from 4.6 to 39.0 mg/g for decaffeinated teas. The antioxidant values varied from 728 to 1686 trolox equivalents/g tea for regular teas and from 507 to 845 trolox equivalents/g for decaffeinated teas.”
Decaffeination doesn’t destroy all of the healthy components of green tea, so if you want to reduce your caffeine intake, you can happily enjoy decaf green tea and know that you’re still getting a good, thought smaller, dose of flavanols.
Since caffeine is a diuretic, I don’t count regular green and black tea as “water.” Non-caffeinated herbal teas do “count” in my world.
