Fourth, avoid sugarless foods. Sorbitol, a natural sugar used in sugarless gums and candies and many diet sodas is hard to digest and causes gas. Fifth, reduce carbonated beverages. The bubbles and fizz in carbonated beverages such as soda, beer, champagne and sparkling water produce lots of gas. Sixth, cut out the caffeine.
Caffeine irritates the colon and an irritated colon is often a noisy, gassy one.
Tea, chocolate and most sodas also contain caffeine. Seventh, increase your exercise. Gas does not stay trapped in your body when you are moving around. Finally, if these changes do not help, you should buy some activated charcoal from the drugstore. This helps absorb gas trapped in your colon.
