You may, or may not have heard that green tea can be rather good for you. But how true are some of the benefits it provides?

It promotes weight loss - It’s thought that by combining the antioxidants catechin and caffeine, it can help speed up the metabolism.

It can however be a great substitute to standard sugary drinks, indirectly saving you calories and helping you lose weight.

It prevents cancer - It’s been reported that green tea can help reduce the likelihood of getting certain cancers. However, a review of 51 relating studies in 2009 found no evidence to link the two.

It cuts cholesterol - The same review in 2014 also found that green tea can have a positive effect in reducing cholesterol. However, it is unclear how much tea you would need to drink in order to see any notable improvements.
