Tea is generally good for your health and green tea in particular (antioxidants, other minerals). Consuming tea can result in healthier living provided it replaces any sugary drinks/soda in your diet. This will result in a reduction in the amount of sugar and calories in your daily intake which will result in a healthier body-mass index in the long term (depending on your age, build, health condition, etc.).

Green tea has been shown to activate your metabolism and increase your metabolic rate which results in faster burning of fat/calories per day. See this article for more: Green Tea Boosts Metabolism, Protects Against Diseases[WebMD].

Another article on green tea and how it helps “natural” weight loss vs. going to the gym, etc. which are activities that help you live better: How Green Tea Can Help You Lose Weight Naturally [Authority Nutrition]

PROs are:

• Plenty of antioxidants which has health benefits (metabolism, etc.)
• Nutritional and “hydrating” beverage with zero calories and fat/sugar

CONs can be summarized into 2 general points:

• “Too much of any good thing is a bad thing” i.e. don’t over-consume (15+ cups per day)
• Green tea can suppress hunger and irregular drinking can change your eating pattern/schedule which can have unintended/negative consequences

If you’re looking for a high quality green tea to consume regularly, I highly recommend this Darjeeling loose leaf variety: The Jade of Bengal | Single-Estate Darjeeling Green Tea

Note: This recommendation is for green tea which is unsweetened and without the addition of any other materials. I highly recommend using only high-quality loose leaf tea to brew the tea in order to get the nutritional/mineral benefits.
