Pros
Green tea is a common health drink that people turn to for many reasons. One reason being the health benefits it can offer to the body. Green tea contains antioxidants called catechins. These have been known to help with certain cancers, diseases, and weight control. The cancers include: oral, prostate, stomach, breast, heart disease, and pancreatic. Green tea has also been known to help prevent the onset of type 2 diabetes and help with weight control by boosting the metabolism and increase fat burning.
Cons
