Studies have estimated that the average person produces about 0.6 to 1.8 liters of gas every day. Gastrointestinal gas has two sources where it is either swallowed (exogenous) or produced by bacteria in the intestines (endogenous). This gas in the intestines is composed of varying amounts of carbon dioxide, oxygen, nitrogen, methane, and hydrogen. Carbon dioxide, oxygen, and nitrogen come from the exogenous source while methane and hydrogen come from the endogenous source where the bacteria in the intestines break down food residue. Based on the analysis of intestinal gas, it comprises mainly of exogenous air and a small amount of endogenous air.
Intestinal gas has a bad odor as the intestinal bacteria produces sulphur-containing compounds. The human nose has the ability to detect hydrogen sulphide and is, therefore, sensitive to the passing of intestinal gas. Gas can be released via the anus as flatus or via the mouth by burping or belching. A normal healthy person passes flatus about 12 to 25 times a day. Generally, swallowed air remains in the stomach before passing through the rest of the gastrointestinal tract in small amounts regularly. It moves rapidly as it is propelled by peristalsis (rhythmic contractions in the gastrointestinal tract). When the gas reaches the colon, movement slows, and gas is released through the anus in small amounts. During sleep, there is very little air swallowed and most gas is passed. This is why there is minimal gas at the beginning of the day.
There are various factors that can influence the amount of gas such as diet, bowel motility, medications, and stress. Read on to learn more about foods that do not cause gas.
Food That Does Not Cause Gas #1: Celery
Celery is an edible plant that is cultivated as a vegetable. It has a long fibrous stalk that tapers into leaves with seeds that are used as a spice. It has an extremely high water (95 percent) and potassium content. Potassium can be beneficial as it helps control water retention and bloating.
Celery is commonly used as a digestive aid to help repair a leaky gut and control gas. The insoluble fiber found in celery further helps the regulation of bowel movements as it benefits individuals with both diarrhea and constipation. Celery is best eaten cooked as it helps to soften the indigestible fibers to reduce gas.
