Health Benefits
Tea has always been a health beverage. As of late this has been more prevalent in the mainstream media and in health journals. The different types of tea are known to have different benefits. Thus a white tea has different health boosting properties than a green or a black tea would.
You’ll hear all kinds of terms thrown around such as “flavonoids”, “antioxidents” and “free radicals.” Know that these don’t have anything to do with flavor, oxidation or radical politics! Flavonoids are a type of antioxident compound which break down free radicals. Free radicals are believed by scientists to cause damage to the body over time.
Tea has been suggested to lower your risk of cancer, prevent heart disease and strokes, boost your immune system, improve bone health and promote proper oral hygeine including improving your breath! Some teas have even been found to assist in weight loss!
Note that while the efficacy of tea’s health benefits is not always the same between men and women, however we all get healthy benefits from drinking tea. Studies have not been able to find any detrimental effects of drinking tea, regardless of the amount you drink. Five, ten, fifteen cups a day… you’re healthy, happy and well hydrated! Bonus for tea being tasty!
