Special Precautions of Oolong Tea
In some individuals, high doses of caffeine may lead to a number of adverse effects (such as anxiety, increased heart rate and blood pressure, and the worsening of ulcer symptoms).
The benefits of Oolong Tea are
- Mental alertness. Drinking oolong tea or other caffeinated beverages throughout the day seems to maintain alertness and mental performance. Combining caffeine with sugar as an "energy drink" seems to improve mental performance better than either caffeine or sugar alone.
- Heart Disease : In a population study published in 2010, researchers found that consumption of oolong tea was linked to a reduced risk of mortality from cardiovascular disease. Participants included 76,979 adults, all of whom were ages 40 to 79 and free of stroke, heart disease, and cancer at the start of the study. In surveying study members about their beverage consumption, the researchers determined that those who drank coffee, green tea, and/or oolong tea on a regular basis had a lower risk of heart disease (compared to those who didn't drink such beverages).Previously published test-tube research suggests that oolong tea may help keep cholesterol in check, possibly due to its antioxidant effects.
- Diabetes : When paired with standard care, oolong may benefit people with type 2 diabetes, according to a small study published in 2003. After drinking 1,500 ml of oolong tea daily for 30 days, diabetes patients experienced a greater reduction in blood sugar levels (compared to those who drank water instead of tea). The study involved a total of 20 diabetes patients, all of whom took hyperglycemic drugs as prescribed.
- Weight Loss : Several studies indicate that oolong tea may help promote weight loss. In a 2009 study of 102 overweight or obese subjects, for instance, researchers concluded that consumption of oolong tea could improve fat metabolism and, in turn, reduce body weight. After six weeks of drinking oolong tea daily, 64 percent of obese subjects and 66 percent of overweight subjects lost more than 2.2 pounds. Overall, 22 percent of participants lost more than 6.6 pounds.Previous studies suggest that oolong tea's anti-obesity effects might be due to its caffeine.
- Preventing Ovarian Cancer. Women who regularly drink tea, including black tea, green tea, or oolong tea, appear to have a significantly lower risk of developing ovarian cancer. One study found that drinking 2 or more cups of tea daily seems to cut ovarian cancer risk by almost half.
- Eczema : A study more than a decade ago in Japan found that oolong tea was effective in easing treatment-resistant eczema
