Certain vegetables, such as lettuce, cauliflower, cabbage, brussels sprouts and broccoli, can increase the amount of gas in the body, according to Mayo Clinic. Hard candy, sugar alcohols and chewing gum also produce excess gas when the body is unable to digest these foods properly.

Patients can prevent excess gas by drinking and eating slowly to reduce the amount of air swallowed, as pointed out by Mayo Clinic. It is best to avoid beer and carbonated drinks because these beverages release carbon dioxide gas. Smoking also leads to an excess amount of swallowed air that can cause excess gas.
