Farts come from?
When we eat, food is digested and absorbed in the stomach and intestines, and most of the nutrients are absorbed and utilized by the body, but there are some components that cannot be absorbed, and these components enter our large intestine. And then it's the turn of our bacterial friends, and the bacteria in the gut will help break down these unabsorbed components. In the process, some gas is produced, which eventually forms the fart that we are familiar with. So,The ** of fart is actually the gas produced by the bacteria in the intestines of the components that are not absorbed during our digestion. They are discharged through the **, giving us moments of joy and embarrassment. Why do some farts stink and some don't?
There are different types of "fart", and the most embarrassing is "stinky fart". Have you ever encountered that embarrassing fart smell?Why do some farts stink unbearably and others don't smell?It turned out,The smell of a fart mainly comes from the sulfides it contains, such as hydrogen sulfide and methyl mercaptan. These sulfides usually come from the breakdown process of proteinsEspecially foods that contain sulfur amino acids. As a result, when you consume more sulfur-containing amino acids, your farts may become more foul-smelling and pungent.

What behaviors can lead to "serial farts"?
The birth of "fart" is a natural process, and our behavior affects the characteristics of fart, and some habits can cause farts to foil frequently. 1.Eat high-fiber foods:Legumes, whole-grain foods and vegetables are difficult to digest and are broken down by bacteria to produce more gas when they enter the intestines. Ways to improve:Adjust the diet structure and reduce the intake of gas-prone foods such as legumes, sweet potatoes, potatoes, yams, and chestnuts. These foods are mainly protein and starch, which will allow chyme to stay in the digestive tract for a long time, causing bacteria to ferment and produce too much gas. 2.Eat too fast:Eating too fast can lead to swallowing too much air, which can also increase fart production. Ways to improve:Change your eating habits and chew your food slowly, 20 to 30 times per bite of food so that you don't swallow too much air. Savoring food not only reduces the number of farts but also helps in better digestion and absorption of nutrients. What behaviors cause "biofarts"?
Some people jokingly compare the stinky fart to a "biochemical fart", so how does a "biochemical fart" develop?1.Eating foods that contain sulfur amino acids:Certain ingredients contained in food, such as onions, garlic, and especially certain dairy products, can increase the sulfide content in the fart, which can increase the smell of the fart. Ways to improve:Reduce the intake of high-fat, high-protein, cold, and spicy foods that easily stimulate the gastrointestinal tract, and increase water intake, so as to avoid the food being decomposed by the flora in the digestive tract and producing a large number of amines, which makes the fart smell very smelly. 2.Gut bacteria are active:Bacterial activity in the gut can also have an impact on fart odor, so maintaining a good balance of gut flora is also key to reducing fart odor. Ways to improve:Some probiotics and prebiotics, such as yogurt, fermented foods, and vegetables, can be ingested to help maintain gut health and reduce odors. Moderate exercise can promote the harmonious peristalsis of the intestines, avoid long-term accumulation of food and excessive fermentation, and also reduce the production of odors. Fart smell is the body detoxifying
Actually,This claim is inaccurate and unscientific. The production of farts has nothing to do with the detoxification process of the bodyAnd it is related to the "birth" and "cultivation" of the "fart" we talked about above. In general,It is normal to fart a few times a day because farts are part of the normal digestive processThey are one of the ways our bodies flush out unabsorbed ingredients. Healthy farts are smelly and mild. While farts inevitably have some smell, healthy farts are usually not too pungent or unpleasant. If your fart smells very bad or unbearable, it may be due to certain foods or an imbalance in the intestinal floraAdjusting your diet and maintaining good gut health can help reduce the smell of fart. However,If there is a change in the number and smell of farts, or if it is accompanied by symptoms such as abdominal pain, bloating, diarrhea or constipation, it may be a sign of certain digestive problems. For example, indigestion, intestinal infections and diseases such as inflammatory bowel disease, colon cancer, etc., can all cause abnormal changes in fart. Therefore, if you notice that your fart is abnormal, it is best to consult a doctor for further examination.

Conclusion
By uncovering the ** of farts and explaining the health knowledge of farts, we can know: more farts and farts smell does not mean that the body is detoxifying. The production of farts is part of the normal digestive process and has nothing to do with detoxification of the body. Therefore, don't be fooled by the statement that "farts are too much, and fart smells are detoxifying the body".
