Question: Does decaf green tea have the same benefits as green tea with caffeine?
First, your site is awesome. I just found it and look forward to spending lots of time here. Congratulations on this wonderful site.

My questions is: Does decaf green tea have the same benefits as green tea with caffeine? I am fibrocystic and try to stay away from caffeine, but it would be worth it to drink the caffeine if this is the only way to derive the wonderful benefits of green tea.

Thank you for your time and consideration.

Answer: Drinking green tea is a great way to get flavanols and antioxidants. Decaffeinating green does have an effect on the healthy components. According to one green tea 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, however, so if you drink the decaffeinated green tea you will just need to drink more green tea to get the same amount of flavanols and antioxidants as regular tea.
