1. As long as the number of cups you drink remains the same, replacing your morning coffee with a cup of green tea will reduce your caffeine intake by about 70%. One cup of coffee contains 100-150mg of caffeine; a cup of green tea has only about 25mg of caffeine. However, there are many variables affecting these numbers. For example, the caffeine content of different types of green tea can vary; also a longer brewing period can result in more strongly caffeinated tea.
2. Green tea contains two other stimulants in addition to caffeine. These substances, theobromine and theophylline, may affect heart rate and the central nervous system in a way somewhat similar to caffeine. These substances are also found in chocolate.
