1. Iced black tea is not a carbonated drink.

2. Because the main ingredients of iced black tea include vitamin B6, protein, pantothenic acid, carbohydrates, folic acid, dietary fiber and other nutrients, and do not contain carbon dioxide, iced black tea is just a beverage. Carbonated drinks refer to drinks filled with carbon dioxide gas under certain conditions. The main ingredients of carbonated drinks include carbonated water, citric acid and other acidic substances, sugar, spices, and some contain caffeine, artificial colors, etc. In addition to sugar, which can replenish energy for the human body, aerated "carbonated drinks" contain almost no nutrients.
