- Turns out that there are only 4 types of tea: green, black, white, and oolong. Herbal "Teas" are not actually tea because they are made from a different plant (i.e. chamomile, peppermint, etc.) and exhibit different nutritional content. Look for the word TEA in the ingredients list to find out if it is actually tea.
- What differentiates the 4 teas? It's all in the leaf - black tea is wilted and fully oxidized, green tea is only wilted, oolong tea is sun-dried and slightly oxidized, and white tea is wilted and partially oxidized.
- What are the health claims? All four teas contain polyphenols - antioxidant compounds that may offer protection from various cancers, lower cholesterol, protect from plaque buildup on teeth, and reduce the risk of heart attack or stroke.
- Can they help cure a cold? Scientific evidence is lacking. Subjective support says that hot tea can be soothing on a sore throat and comforting.
- Try adding citrus - such as fresh squeezed lemon or orange juice - to increase the nutritional content (think Vitamin C!).
- All four teas contain caffeine (the highest content in black) and therefore may interfere with the ability to fall asleep - so be careful when drinking before bedtime. On a beneficial side, the caffeine is shown to increase mental alertness.
- Beware of bottled or prepared teas - they may contain sugars or other additives.
