Oolong Tea? What is it?

Oolong tea is a traditional drink in China. It has been a part of Chinese culture for its various health benefits for a long time. 

Oolong tea is made from Camellia Sinensis plant leaves. These leaves are also used in the making of green and black teas. The basic difference between the oolong and the other two types of teas is the way they are processed. 

All tea leaves do the process of oxidation due to the presence of some certain enzymes in them. The oxidation process is what turns the leaves into deep black color leaves. 

The leaves used in black tea are oxidized until their color changes to black, whereas the green tea leaves are not oxidized to this extent. The leaves used in the oolong tea are between these two and are oxidized partially. 

The characteristic taste and the color of oolong tea come from this partial oxidation process. But, these color characteristics of this tea can vary from brand to brand.

A recent study on oolong tea with diabetes patients has proven that the patients who took 1.5 liters of oolong tea per day had up to 30% reduction in their blood sugar levels after 30 days. Another study shows that those who took 1 liter of oolong tea for 30 days had a 3.3% reduction in blood sugar levels. 

The oolong tea studies don’t show just the good effects, but a recent study shows that those who had more than 480ml or more of oolong tea per day had higher chances of diabetes.

In the study, it was seen that both caffeine alone tea antioxidants + caffeine increased calories burning. But, only tea antioxidants + caffeine caused fat burning. 

It proves that the fat-burning effects of tea are also due to plant compounds and not the caffeine alone. 

Furthermore, the oolong tea benefits were varying from participant to participant, which shows that it has different effects on person to person basis.
