Hot Findings on Iced Tea

by Diane Lofshult on Jul 01, 2005

Recent studies have extolled the virtues of different varieties of tea, which contains powerful antioxidants that can ward off cancer and heart disease. But most studies to date have focused on home-brewed hot tea. To determine whether today’s convenience cold teas pack the same healthy punch, researchers at compared the total antioxidant power, or oxygen radical absorption capacity (ORAC), in different iced-tea products. Here’s what they found:

  • Most of the homemade teas tested did contain more antioxidants than convenience teas, which tend to lose nutrients when processed.
  • Black and green teas had similar (high) levels of antioxidants.
  • Teas brewed hot and then chilled did not contain more antioxidants than teas designed to “brew” in the refrigerator.
  • The teas that won accolades as having “excellent” ORAC levels were Salada Green Tea bags (prepared overnight in the fridge); Tetley Original Blend black tea bags (hot-water brewed); and Nestea Liquid Concentrate Iced Tea (green tea with honey).
