苏打, commonly known as soda, is a carbonated beverage that is often sweetened and flavored. It is made by dissolving carbon dioxide gas in water, creating bubbles that give it a fizzy texture. Many sodas contain added sugars, artificial flavors, and colors, making them popular choices for refreshment. Soda comes in various types, including colas, fruit-flavored drinks, and diet options. Some well-known brands include Coca-Cola and Pepsi. While enjoyed for their taste, sodas are often criticized for their high sugar content and potential health effects when consumed in excess.
