Adding more fiber to your diet from fruit, vegetables, beans, or whole grains can cause temporary gas that may decrease over time (roughly 2-4 weeks) as your body adjusts. The amount of gas will vary from individual to individual. It’s important to eat fruit and vegetables, not only because of the fiber, but the many other important nutrients and beneficial compounds that we don’t even fully understand yet. The following tips may also help prevent gas:
Eat more slowly
Chew food thoroughly
Walk for 10-15 minutes after eating
Do not chew gum
Do not drink carbonated beverages
Avoid artificial sweeteners, such as sorbitol and mannitol, found in some sugar-free foods, gums and candies.
