Black teas contain the highest levels of caffeine among all types of tea. For someone who is looking for an efficient energy boost, this would be a great choice. However, for caffeine sensitive individuals, consumption of black tea should be moderate. Black tea does contain low levels of catechins, but is noted for having the highest levels of theaflavins and thearubinins.

As more research is showing, these compounds are just as effective as the catechins in green tea in preventing heart disease, stroke and cancer, and lowering cholesterol. So don’t think that your morning black tea isn’t as healthy as your cup of green tea in the afternoon. You are just consuming a different variety of healthy compounds.
