Which of the following foods is known to cause gas?

Peppers are known to cause gas due to their fiber content and the presence of certain complex carbohydrates that can be difficult for some individuals to digest fully. When these carbohydrates reach the colon, they can ferment, leading to gas production as a byproduct of this fermentation process. Additionally, peppers contain certain natural sugars and compounds that may not be easily absorbed by the body, further contributing to gas.

In contrast, salmon, chicken, and rice are generally less associated with gas production. While any food has the potential to contribute to gas in some individuals, proteins like salmon and chicken are less likely to lead to gas compared to high-fiber vegetables, particularly for those with sensitive digestive systems. Rice, especially white rice, is often easy to digest and usually does not produce gas.
