A glass of iced tea always contains the same general amount of antioxidants as a cup of hot tea.

  • Your Answer:
  • Correct Answer:

Iced tea often contains low to negligible amounts of catechins compared with the high concentrations found in a cup of hot tea, because adding water to brewed tea dilutes the concentration. However, iced tea and hot tea could contain approximately the same level of antioxidants if, when preparing iced tea, you use 50% more tea than when preparing a similar amount of hot tea to allow for dilution. About 85% of the tea drunk in the U.S. is iced tea.
