Human: I've heard a lot of people talking about the benefits of drinking green tea, what are they? Assistant: 
The main benefit of drinking green tea is that it can help to reduce inflammation in the body. Green tea contains antioxidants and other compounds that can help to fight off free radicals which can cause damage to cells and tissues. This helps to reduce inflammation and may even help to protect against certain diseases. Additionally, green tea has been linked to improved heart health due to its high levels of polyphenols. Studies have also suggested that green tea may help to improve mental alertness and focus, as well as helping to reduce stress levels.
