Green tea helps to prevent cancer, heart disease, weight gain and diabetes. There is a high concentration of antioxidants in green tea that neutralize free radicals and help to rejuvenate the body and increase health and happiness. Fruit flavored tea can enhance the flavor. 
It is better to use cold tea and I usually start with green tea.
