Is Flatulence Good for You? (Does It Depend on the Smell?)

Jillian Levy, CHHC via Dr. Axe – Most of us have been there: experiencing excessive farting that feels out of our control and causes a whole heck of a lot of embarrassment. While the average person farts nearly every day, some people deal with a bloated stomach and excessive flatulence more often than others. One of the most aggravating things about having gas is that it can seem impossible to minimize and to narrow down the exact culprit, considering dozens of different things can potentially be to blame. As you’ve probably experienced firsthand many times, some farts can be pretty foul-smelling and noisy, while others easily slip below the radar. Wondering how much farting is too much? A mostly healthy person might pass gas 14–18 times per day, sometimes not even realizing it because the farts are mostly silent and odorless. A mostly healthy person might pass gas 14–18 times per day Rather than how often you fart, however, you might want to take a look at the smelliness of your flatulence and to examine other digestive symptoms present in order to determine if it’s really become a problem. Is there likely anything to be worried about when it comes to your gas? Yes and no. Some flatulence is normal, especially when eating a whole foods, high-fiber diet — but excessive gas coupled with other symptoms can be a sign that something inside is going wrong, especially when it comes to digestion of certain foods. Too much farting can be a warning sign that normal intestinal gas dynamics have become compromised. This might result in subtle dysfunctions in intestinal motility, bacteria growth or changes in the microbiome composition taking place. Keep reading to learn more about flatulence and when you should and should not be concerned about your farts. What Is Flatulence? What is a fart exactly? A fart, also called gas, “passing wind” or flatulence, is caused by the internal buildup of gases that are formed during the process of digestion and respiration. The causes of farts, and how they develop within the digestive tract vary considerably depending on the person and circumstance. The main type of gas that gets trapped inside the body and leads to flatulence is nitrogen, which researchers estimate accounts for about 20 percent to 90 percent of all the gas that causes farts. Followed by nitrogen, carbon dioxide also contributes to the gaseous volume of farts (about 10 percent to 30 percent) along with oxygen (up to 10 percent), methane (around 10 percent) and hydrogen (about 10 percent to 50 percent). Methane and hydrogen are actually both flammable gases — which explains why you might have seen some cartoon characters light their farts with a flame when you were a kid. The combination of gases described above usually causes a smell because some contain sulfur, the same smelly compound found in foods like eggs or cruciferous vegetables. Why is there such a range in the percentages of gases within a fart and the level of smelliness, depending on the specific person? This has to do with how much air is swallowed by someone in a typical day, the types of foods within someone’s diet, and also the internal chemical reactions taking place within the microbiome or intestines during digestion. The severity of smells associated with flatulence mostly has to do with the percentage of different gases present in the body at any given time. Surprisingly, most of the gas within a fart is odorless, and only a very small percent (around 1 percent) causes the signature foul smell of farts. The reason for stinkiness in general comes down to how much sulfurous gasses form within the intestines. Within a fart, several sulfur-related compounds develop that contribute to the intensity of the fart’s smell. These include: Hydrogen sulphide: This is the component of a fart that usually smells like rotten eggs. Not only does it smell unpleasant, but it’s also flammable and can be toxic when consumed in large amounts. The human body makes some of its own hydrogen sulphide, but interestingly, it’s also produced within the environment in things like swamps, sewage systems and certain types of explosive volcanic rock. Methanethiol: This is found naturally within the human body, mostly within the blood and brain. Ever open up your refrigerator and get a strong whiff of leftover veggies? Methanethiol has a strong smell similar to cruciferous veggies, including broccoli or cabbage. This same compound also contributes to other types of body odors, including bad breath. Dimethyl sulphide: Here’s another chemical compound that contributes to the smelliness of veggies. This is responsible for the smell produced when you cook things like Brussels sprouts. It’s present in foods along with methanethiol and created from the formation of certain bacteria. Causes You’re probably wondering what causes your gas accumulation, right? Excessive gas and gas pains can be attributed to all sorts of health problems, normal variations in hormonal levels that affect digestion (such as your menstrual cycle) or specific foods. While the triggers are somewhat different from person to person, the way that gas forms in the body is mostly the same. Within the body, gas travels down the same pathway in your digestive system as poop does. Eventually, accumulated gas makes its way to through your intestines and out of your colon, just like feces. Along the way, certain things can stop or interfere with the normal release of built-up gas, causing gas pains, bloating and indigestion. This unpleasant feeling is a sign that you’re having a hard time ridding your body of excess gas — possibly because certain foods in your diet are irritating your gut or digestive organs, causing side effects like bacteria growth or fermentation along the way. Bloating and gas usually go hand in hand because when a certain amount of gas is retained within the gut, people develop abdominal distension (a puffy belly) and various gassy symptoms. Just like farting, abdominal distension is related to the volume of gas within the gut and depends both on intestinal motor activity (gas is better tolerated when the gut and digestive muscles are relaxed) and the inner distribution of gas. Some of the reasons gas gets trapped inside the body abnormally include: Swallowing air (aerophagia): This involves inadvertently swallowing air that accumulates in the stomach and is then released by belching or farting. This process is triggered by changes in the muscles that control the intake of air, followed by repetitive and ineffective attempts of belching that causes air to be introduced into the stomach. One reason you might be swallowing air and farting as a consequence? You could be eating too fast and therefore not chewing your food properly. Gaseous odor accumulation: Smelly farts are usually the cause of gas produced by colonic bacteria during fermentation of unabsorbed food residues arriving into the colon. Changes in the microflora: Gas also depends on the composition of the colonic flora — in other words the type of bacteria living within the digestive system. We know that each person is different in terms of microbiome composition, which means inter-individual variations exist that might contribute to, or protect us from, excessive gas production and evacuation. Constipation: Impaired anal evacuation produces gas retention. Constipation also prolongs the fermentation process of foods in the digestive system, increasing internal gas production. Here’s the million-dollar question: Why do some farts make a noticeable sound, while others are “silent but deadly”? This has to do with the alignment of muscles within your colon or rectum. Certain muscles help control how quickly gas is released, either tightly keeping gases inside or allowing them to be released more quickly, which can cause a sound. Know someone who can “fart on demand”? That’s likely because that person’s sphincter muscles, the ones that control the gateway of gas and waste out of the body, are easily relaxed, which lets them release internal gases whenever they want to. Of course, diet has an effect on flatulence as well, and underlying conditions can contribute to gas and farting. Are Farts Bad for You (or Beneficial)? Farting is considered a normal reaction within the human body and something we all deal with at one time or another. Because it’s the act of releasing internal gas from the body, just like a burp or even breathing, it’s usually harmless and in fact needed for normal metabolic functions. Most of the time your farts are just inconvenient but not something to necessarily get riled up about. In fact, they might even be protective in some instances! That’s right — your farts might be a clue that your “gut bugs” are well-fed and working hard and that your diet is a mostly healthy one. Diets high in fiber-rich foods after all tend to cause gas, but they also feed good bacteria that make up your immune system and help protect you from various diseases, like heart disease, cancer, diabetes and obesity. Aside from being a sign that you’re eating plenty of fiber, gases within your farts might even be beneficial. Farts contain hydrogen sulphide, a gas produced by certain natural bodily processes and needed as part of cellular functions. While I wouldn’t necessarily go smelling yours, or anyone else’s, farts just yet, it’s possible that inhaling hydrogen sulphide (yes, from your very own farts!) in small doses might help protect cells’ mitochondria and stop cellular damage at some level. On the other hand, excessive farting can be a sign that digestive processes are going amuck and that an underlying issue might be blame. Some underlying reasons for excessive gas accumulation can include: food sensitives or intolerances (see the list of common culprits below) fermentation of bacteria within the gut from eating FODMAP foods leaky gut syndrome or digestive disorders, including Crohn’s, celiac disease and irritable bowel syndrome constipation SIBO (small intestinal bacteria overgrowth)/excessive bacteria in the small intestine. Normally food intermingles with digestive juices in the intestines and nutrients are absorbed into the bloodstream while waste is sent to the colon, but with SIBO, malabsorption occurs, particularly of fat-soluble vitamins and iron, leading to abnormal bacteria growth and gas. How do you know if your gas is something to actually be worried about? Check if you experience other warning signs at the same time as being very gassy. When you’re up against a lot of flatulence, look for other abnormal symptoms including: weakness or fatigue skin rashes, acne or hives signs of allergies, like watery eyes and itchy throat constipation or diarrhea blood in your stool or urine pain around your lymph nodes, including in your groin, throat or armpits changes in your body temperature, weight, sleep and menstrual cycle Natural Remedies If you find yourself repeatedly dealing with bad gas, the first thing to do is address your diet. You might be having trouble breaking down certain foods or experiencing an accumulation of sulfur, bacteria or yeast. The tendency for foods to cause excessive gas varies from person to person considerably, so it usually takes some trial and error to figure out what your biggest triggers are. That being said, there are some “common culprits” in the world of farting that are likely involved in your struggle. Some of the Worst Foods for Gas Beans: Perhaps more than any other food, beans are notorious for causing gas. That’s because they contain a type of carbohydrate called polysaccharides, which easily ferment once they enter the gut. The bacteria living in your gut thrive off of these carbohydrates, which causes fermentation and an increase in gas. Luckily you don’t have to avoid beans and legumes all together — soaking them overnight prior to cooking helps make them more digestible (the same applies to nuts, which are similar in terms of their carb content), which is good news considering they can provide plenty of nutrients and fiber. Dairy: Lactose intolerance is a common digestive problem worldwide, although many people might be unaware that they cannot properly digest foods containing milk, cheese, yogurt or traces of...

Game-Changing Technology to Remove Carbon Dioxide From Air

AHA Publisher — Fri, 04 Feb 2022 08:00:15 +0000

American Physiological Society (APS) via Newswise – University of Delaware engineers have demonstrated a way to effectively capture 99% of carbon dioxide from air using a novel electrochemical system powered by hydrogen. It is a significant advance for carbon dioxide capture and could bring more environmentally friendly fuel cells closer to market. The research team, led by UD Professor Yushan Yan, reported their method in Nature Energy on Thursday, February 3. Game-Changing Tech for Fuel Cell Efficiency Fuel cells work by converting fuel chemical energy directly into electricity. They can be used in transportation for things like hybrid or zero-emission vehicles. Yan, Henry Belin du Pont Chair of Chemical and Biomolecular Engineering, has been working for some time to improve hydroxide exchange membrane (HEM) fuel cells, an economical and environmentally friendly alternative to traditional acid-based fuel cells used today. But HEM fuel cells have a shortcoming that has kept them off the road — they are extremely sensitive to carbon dioxide in the air. Essentially, the carbon dioxide makes it hard for a HEM fuel cell to breathe. This defect quickly reduces the fuel cell’s performance and efficiency by up to 20%, rendering the fuel cell no better than a gasoline engine. Yan’s research group has been searching for a workaround for this carbon dioxide conundrum for over 15 years. A few years back, the researchers realized this disadvantage might actually be a solution — for carbon dioxide removal. “Once we dug into the mechanism, we realized the fuel cells were capturing just about every bit of carbon dioxide that came into them, and they were really good at separating it to the other side,” said Brian Setzler, assistant professor for research in chemical and biomolecular engineering and paper co-author. While this isn’t good for the fuel cell, the team knew if they could leverage this built-in “self-purging” process in a separate device upstream from the fuel cell stack, they could turn it into a carbon dioxide separator. “It turns out our approach is very effective. We can capture 99% of the carbon dioxide out of the air in one pass if we have the right design and right configuration,” said Yan. So, how did they do it? They found a way to embed the power source for the electrochemical technology inside the separation membrane. The approach involved internally short-circuiting the device. “It’s risky, but we managed to control this short-circuited fuel cell by hydrogen. And by using this internal electrically shorted membrane, we were able to get rid of the bulky components, such as bipolar plates, current collectors or any electrical wires typically found in a fuel cell stack,” said Lin Shi, a doctoral candidate in the Yan group and the paper’s lead author. Now, the research team had an electrochemical device that looked like a normal filtration membrane made for separating out gases, but with the capability to continuously pick up minute amounts of carbon dioxide from the air like a more complicated electrochemical system. In effect, embedding the device’s wires inside the membrane created a short-cut that made it easier for the carbon dioxide particles to travel from one side to the other. It also enabled the team to construct a compact, spiral module with a large surface area in a small volume. In other words, they now have a smaller package capable of filtering greater quantities of air at a time, making it both effective and cost-effective for fuel cell applications. Meanwhile, fewer components mean less cost and, more importantly, provided a way to easily scale up for the market. The research team’s results showed that an electrochemical cell measuring 2 inches by 2 inches could continuously remove about 99% of the carbon dioxide found in air flowing at a rate of approximately two liters per minute. An early prototype spiral device about the size of a 12-ounce soda can is capable of filtering 10 liters of air per minute and scrubbing out 98% of the carbon dioxide, the researchers said. Scaled for an automotive application, the device would be roughly the size of a gallon of milk, Setzer said, but the device could be used to remove carbon dioxide elsewhere, too. For example, the UD-patented technology could enable lighter, more efficient carbon dioxide removal devices in spacecraft or submarines, where ongoing filtration is critical. “We have some ideas for a long-term roadmap that can really help us get there,” said Setzler. According to Shi, since the electrochemical system is powered by hydrogen, as the hydrogen economy develops, this electrochemical device could also be used in airplanes and buildings where air recirculation is desired as an energy-saving measure. Later this month, following his dissertation defense, Shi will join Versogen, a UD spinoff company founded by Yan, to continue advancing research toward sustainable green hydrogen.
