Green Teas: Tea is derived from a tree called camellia sinensis. The leaves contain antioxidant polyphenols which have an anti-carcinogenic effect. The lighter the tea, the less it has been processed. White and green teas are especially helpful. Black teas have been dried and fermented. The linus pauling institute reported a study that suggest extracts from green tea can act as a plant-based alter >>.

A 37-year-old member asked:

How healthy is green tea?

Unclear: Green tea may have a significant amount of caffeine in it, which can cause elevated blood pressure or heart palpitations. However, it may provide some health benefits. There are no long term studies available yet about the health benefits of green tea, so proceed with caution.

Does green tea have any side effects?

Yes, from caffeine: Green tea has many health benefits, due to its antioxidant effects. There is evidence it can prevent cancer and cardiovascular disease, improve immune function, prevent tooth decay, lower blood sugar and stimulate weight loss. It is safe and generally well tolerated, but it does contain caffeine (though decaffeinated forms are available). Thus, the most common side effects are due to excess caffeine, including insomnia, anxiety, heart palpitations, nausea and vomiting. However, the amount of caffeine in green tea is about 1/4 the amount in coffee, so one will not likely experience such effects unless they drink large quantities. There is also the potential for large amounts of green tea to interact with certain medications- for example, it can reduce the effects of Coumadin (warfarin) (but then again, thousands of substances interact with coumadin!) and lower blood levels of lithium.

Yes: Green tea does increase your metabolism, albeit only slightly. The resulting weight loss is not immediate or drastic, but the molecules in green tea do help increase metabolism without increasing heart rate. Green tea has many health benefits such as protecting the heart and helping prevent cancer. So bottoms up!
