Carbonated soft drinks are beverages that contain dissolved carbon dioxide gas, which creates bubbles and a fizzy texture. These drinks typically combine carbonated water with sweeteners (like sugar or artificial sweeteners), flavours (such as cola, citrus, or fruit), and sometimes colours and preservatives to produce a refreshing taste. People around the world consume them cold as thirst‑quenchers, mixers with other beverages, or as accompaniment to meals and social occasions. Carbonation adds not just texture but can enhance the sensory experience, making these drinks feel more refreshing, especially in warm weather or after physical activity. Beyond enjoyment, some carbonated drinks now include functional ingredients like prebiotics or vitamins aimed at supporting digestive health or offering lower‑sugar alternatives, reflecting evolving consumer preferences for healthier options. In addition, many brands have expanded into zero‑sugar or reduced‑calorie versions to cater to those monitoring caloric intake or sugar consumption a trend seen widely in the beverage industry.
