What beverage causes intestinal gas in adults?

Carbonated Beverages, such as soda and sparkling water, can cause intestinal gas in adults due to the carbonation, which introduces carbon dioxide into the digestive system. Additionally, certain beverages containing high levels of sugar or artificial sweeteners, like sorbitol or mannitol, can contribute to gas production during digestion. Drinking these beverages quickly can also exacerbate the issue by swallowing excess air.
