Bottled Tea vs. Brewed Tea
Antioxidants are substances that protect cells against damage from unstable molecules called free radicals. They may play a role in preventing a host of diseases, including cancer, cardiovascular disease and Alzheimer’s.
Li and colleagues measured the level of polyphenols of six brands of tea purchased from supermarkets. Half of them contained what Li characterized as “virtually no” antioxidants. The rest had small amounts of polyphenols that Li said probably would carry little health benefit, especially when considering the high sugar intake from tea beverages.
