Oolong Tea: Other Health Benefits
Posted by Susan Lutfallah on June 7, 2009
In addition to its weight loss benefits, oolong tea has gained immense popularity for its many health benefits – in fact, there are hundreds of studies done on the various benefits of oolong tea.
Firstly, oolong tea promotes general health and well-being since it contains a large quantitiy of polymerized polyphenols which have been shown to:
• promote strong, healthy teeth;
• improve cognitive functioning and mental well-being;
• prevent eczema, allergies;
• clarify skin aberrations, giving it a healthy, radiant look
• strengthen immune system
Again, oolong tea has long been consumed in Chinese society for centuries, and has been consumed for its many health benefits – nowadays, many recent studies have shown that oolong tea can help reduce the risk of cancer, and in some cases it has been shown to inhibit the growth of cancer cells.
In one study, researchers found that oolong tea polyphenol extract (OTPE) induced apoptosis (programmed cell-death) in human stomach cancer cells – this means that the OTPE was able to trigger a genetic program in these stomach cancer cells which caused them to die. Moreover, another study found that oolong tea contains the compound chafuroside, which is a new flavone derivative – chafuroside has been found to be a strong anti-inflammatory compound, and the same study found that chafuroside from oolong tea maybe a good chemopreventive agent against colon cancer.
Not so surprisingly, there are numerous studies that demonstrate the anti-aging benefits of oolong tea. In fact, one study performed on older Chinese adults found that regular consumption of oolong tea is associated with lowered risk of age-related cognitive impairment and decline. The study involved 2501 subjects over 55 years old, and they found that total oolong tea intake was significantly associated with a lower prevalence of cognitive impairment.
A 2001 Japanese study found that drinking 1 litre of wulong tea a day can take 2 years off the internal organ ‘age’. To point out the weight loss benefits of oolong tea, researchers also reported that out of the 11 participants, 9 experienced 2 centimetres reduction in their waist size and 8 experienced 2 centimetres reduction in their upper arms. Finally, they also observed lower bad cholesterols levels (LDL levels).
Oolong tea also contains high concentrations of antioxidants which are beneficial for your health. Here’s a list of all the wonderful things antioxidants do for your body:
– Helps inhibit growth of cancer cells
– Reduce high blood pressure.
– Protection against getting a stroke.
– Improved blood flow to the heart.
– Reduce cholesterol.
– Helps inhibit the formation of blood clots in artery walls.
– Maintains even blood sugar levels.
– Lowers the risk for osteoporosis.
– Enhances immune function and helps fight infections.
– Inhibits the growth of bacteria that can cause gum disease, cavities, and bad breath.
Reduces Blood Pressure
Oolong tea has also been shown in studies to reduce the risk of hypertension – in fact, many of these studies come from Chinese research done on various segments of the Chinese tea drinking population. One study measured the risk of newly diagnosed hypertension in 1507 subjects aged 20 years and older. In this study, researchers found that the risk of developing hypertension was reduced by 46% for subjects who drank 120 to 599ml of oolong tea per day – staggeringly, for subjects who drank more than 600ml of tea, the risk of hypertension was reduced by 65%.
