Foods that Causes Gas and Bloated Feeling

Many foods contain soluble and insoluble fiber. Soluble fiber dissolves easily in water and takes on a soft, gel-like texture in the intestines. Found in oat bran, beans, peas, and most fruits, soluble fiber is not broken down until it reaches the large intestine, where digestion causes gas.

No: do not cause gas. Gas is a by-product of the effects of gut  on ingested food.

In the meantime, though, there are a few common culprits that often cause gas, flatulence, and digestive discomfort. Here are seven foods you might want to examine more closely to see if they’re the cause of your tummy troubles.

The sugars that cause gas are raffinose, lactose, fructose, and sorbitol.

The third cause is side effects caused by certain medications such as antibiotics or cholesterol lowering drugs. These medications cause gas to enter the lumen from the blood stream. This is a diffusion of gas into the lumen by varying intestinal pressures. These drugs that selectively inhibit bacterial hydrogen breakdown noticeably increase the amount of hydrogen excretion (flatulence).There is growing evidence that some people with IBS may be more prone to produce gas (or excess gas) from foods that do not cause gas, or only cause minimal gas, in people without IBS. This is thought to be due to a disruption of the normal balance of bacteria in the gut.

For instance, some bacteria in the large intestine can destroy the hydrogen that other bacteria produce. Therefore, some people have more and others have less gas.The bacterial system in the human colon is incredibly complex, with more than 400 different species of microbes. Acacia provides fuel for microbial fermentation. Interestingly, fermentation is an action that many people think of as causing an increase in gas. However, it is foods that rapidly ferment in the gut that can cause high gas production. Foods such as Acacia ferment slowly, and this fermentation promotes growth of the gut's beneficial lactic acid bacteria (such as bifidobacteria and lactobacilli). This in turn helps actively reduce gas and bloating, which is exactly the goal you're trying to reach. In addition, the fermentation of Acacia leads to short chain fatty acid production, which lowers the ph balance of the gut, allowing beneficial conditions for lactic acid bacteria to thrive. The greater short chain fatty acid production may also reduce inflammation of the gut and colorectal cancer risk, two nice bonuses.Other causes of gas may include surgery, changes in hormone levels and medical conditions such as gastrointestinal disorders and food allergies. If you experience gas for these reasons, it’s best to report this discomfort to your healthcare provider.In general, foods with natural sugars, high-fiber foods, and starchy foods are all likely to cause gas because of the way the body breaks them down, or has difficulty breaking them down.

Contrary to many other health conditions related to diet, a healthier diet may actually make your gas worse rather than better. Bacteria breaks down the food you eat once it gets to your colon, and that bacteria produces gas. Swallowing a lot of excess air while you eat can also cause more gas in your digestive tract. Some of the bacteria in the intestines includes hydrogen, carbon dioxide and methane.
