Current research targeting oolong tea health benefits supports ancient wisdom about this delicious, healing tea.
As oolong tea becomes better known around the world, the many health benefits of oolong tea will become the target of increasingly more research studies.
Even though oolong health benefits have been treasured in China for centuries, oolong tea and its healing properties are still new to many of us.
As you get to know the delicious taste of oolong tea, know that you are enjoying the following oolong tea health benefits, as well. More oolong tea information is available in current research focusing on...
A 2009 population study at Kyoto University in Japan involved almost 77,000 participants between the ages of 40 and 79, each with no history of stroke, coronary heart disease, or cancer at the onset of the study.
Research results indicated that regular consumption of oolong and/or green tea reduces the threat of heart disease and lessens the risk of death from cardiovascular disease. Click here to read the research abstract.
Oolong tea may also protect you from heart disease by helping to lower high cholesterol levels.
High levels of LDL cholesterol can increase your risk of heart attack, and a 2003 study at the Institute for Health Care Science in Osaka, Japan, found that the antioxidants in oolong tea may lower high LDL levels.
In this 2004 study of the long-term effects of drinking tea on high blood pressure, results showed that drinking oolong or green tea regularly can significantly lower your risk of developing high blood pressure.
In the study, which examined the tea drinking habits of over 1500 participants in Taiwan, the risk of developing hypertension decreased by 46 percent for habitual tea drinkers who consumed at least 120 ml (1/2 cup) oolong or green tea daily for at least one year. For those who drank over 600 ml (2 1/2 cups) oolong or green tea each day, that risk was decreased by 65 percent.
Tea consumption for more than a year did not lead to additional risk reduction.
Twenty participants with type 2 diabetes taking prescribed hyperglycemic medication participated in this 2003 study conducted in Taiwan.
After consuming 1500 ml (about 6.3 cups) Chinese oolong tea each day for 30 days, the study participants had significantly lower blood sugar levels. (Chinese, rather than Taiwanese, oolong tea was selected for the study because its shorter oxidation process typically results in higher levels of antioxidants in the tea.)
More oolong tea health benefits... the study also found that oolong tea in combination with hyperglycemic medication was more effective in lowering blood sugar levels than the medication alone.
Even though oolong tea has been valued in China for many years for its health and wellness properties, many of us are still just getting to know this wonderful tea!
While many of us don't bother with scientific research to tell us about the health benefits of tea, current studies do provide more oolong tea information and confirm the traditional wisdom about the many healing benefits of oolong that has been passed down through the generations.
