Processed foods that are high in sugar, such as candy, are examples of fast carbs. In general, slow carbs, or carbohydrates that are digested by the body more slowly, are considered more healthy, whereas fast carbs, or carbohydrates digested by the body more quickly, are considered less healthy.To determine the rate at which carbohydrates are digested, you can use the glycemic index scale.A simpler method, however, is to classify foods that are high in fiber and nutrients as slow carbs and more processed foods that are lower in fiber and nutrients and higher in sugar as fast carbs. simpler method, however, is to classify foods that are high in fiber and nutrients as slow carbs and more processed foods that are lower in fiber and nutrients and higher in sugar as fast carbs.
Not all types of fiber cause gas. Fiber comes in two types, soluble and insoluble. Foods that contain soluble fiber tend to produce more gas than foods high in insoluble fiber. Some sugars as well as fiber can cause gas; foods that contain both soluble fiber and sugars that cause gas have extra gas-producing potential. The types of bacteria you have in your gut -- which varies from person to person -- can also affect how much gas you produce.
One top offender is dietary fiber. Foods that are high in fiber, such as beans, whole grains, and fresh fruits and vegetables can make you gassy. Unfortunately, increasing your fiber intake can help treat other symptoms of IBS, but can cause bloating and gas. You can try bringing up your dietary fiber slowly to allow your digestive system to get used to it, or you can try using supplemental fiber.
