So slow down and enjoy your food. Your meals should last at least 30 minutes. Also, keep in mind that digestion begins in the mouth, and you can decrease bloating just by chewing your food more.
There's another benefit to slowing things down: When you take your time to thoroughly chew and taste your food, your snack or meal becomes more satisfying. And studies have shown that if you eat more slowly, you may end up eating less.
