When you say green tea, does that apply to the hot tea only or do teas like arizona green tea have similar effects?

Fresh-brewed best!: Teas like Arizona green tea lose over 90% of their beneficial antioxidants and are loaded with sugars, so are not a healthy choice. Fresh-brewed green tea is MUCH healthier- it is OK to cool it but it should be consumed within hours of being brewed for maximum benefit. You can add a bit of sugar or erythritol.
