The main causes of intestinal gas
Flatulence results from swallowed air and fermentation in the intestines. Swallowing air by eating too quickly or talking during meals increases the amount of gas. Carbonated drinks amplify this phenomenon.
Diet plays a central role. Some foods ferment more easily, producing more gas. Cruciferous vegetables like cabbage, broccoli, and cauliflower are among the best known. Legumes, rich in fiber, can also cause flatulence when consumed in large quantities. Similarly, some poorly absorbed sugars, found in milk or certain fruits, ferment in the colon and generate gas.
