More Research about the Benefits of Using Green Tea

Much current scientific research is targeting the benefits of using green tea, thanks to tea's renewed popularity and also to traditional knowledge that touts tea as an amazing health and wellness beverage.

Teas from the Camellia sinensis tea plant are coming into their own, as people around the world grow to appreciate that these teas have so much more to offer than a soothing cuppa at the end of the day!

Green tea, in particular, has caught our attention, and its popularity is sure to continue to grow, as more and more of us discover the multitude of health benefits this simple tea provides.

Benefits of using Green Tea

Let's take a look at more current research about the benefits of using green tea. (If you're not really a research person, you can find an overview of the benefits of using green tea on our Green Tea Benefits page.)

Benefits of using Green Tea for Weight Management

A 2005 Japanese study focusing on tea and weight loss found that oolong tea enriched with green tea extract was much more effective for weight loss than oolong tea on its own.

After 12 weeks of drinking the enriched oolong tea, the overweight participants lost more weight and had greater reduction of BMI (body mass index) and waist measurements than those participants who drank oolong tea without the supplementary green tea extract.

The higher levels of catechins (antioxidants) in the oolong tea/ green tea extract mixture were credited for the research results. For more information, you can find the research abstract here, or view the full article here.

Green Tea fights Cavities and Tooth Decay

In 1995, a study of 14-years-olds in England discovered that tea drinkers had fewer cavities and better overall dental health when compared to those who typically chose coffee or carbonated drinks - and this was true whether or not sugar was added to the tea!

More information about this study targeting beverages and dental health can be found here.

Green Tea protects against Diabetes

A study involving 300 older men and women (aged 65 to 100) living on various Mediterranean islands found that drinking green or black tea regularly can reduce the risk of developing diabetes.

Results from this study, which took place between 2005 and 2007, showed that long-term consumption of green or black tea - 1 to 2 cups each day - can significantly lower fasting blood sugar levels, leading to a lower risk of developing diabetes.
