Tea is the most commonly consumed beverage in the world after water. Green Tea, in particular. If you need to grab a drink when you're out, Green Ice Tea of any brand is the most convenient option. But there are some problem.
There's good evidence that Green Tea can be good for your health, but a bottle of iced tea is just another soft drink. Iced tea isn’t as healthy as it’s sometimes cracked up to be. First of all, ready-made Green Tea contains much lower levels of flavonoids than freshly brewed tea because it’s made from Green Tea extract, not from fresh brewed Green Tea. For example Lipton Ice Tea Green (made from Green Tea extract) contains 170mg of flavonoids per 500ml bottle and you'd get about 700mg of flavonoids from the same quantity of freshly brewed Green Tea. So you can’t get the same health benefits from iced tea diet as from a traditional cuppa.
The second problem is the plenty of sugar most brands do contain. All the brands of bottled Green Tea are heavily sweetened with either sugar or artificial sweeteners. It ranges from 7 to 11 or even more teaspoons of sugar per 500ml bottle. It’s not useful for your teeth and specially for your weight. If that's not enough some brands offer a diet Green Tea version sweetened with aspartame and ace-k. So you don’t enjoy pure Green Tea because of enjoying the very subtle flavor.But Green Tea is very good without sweetener of any kind and if you get real good tea (imported from China or Japan) you don't need to put anything else in it to make it taste better.
