Why do fights smell like poop?
Flatulence: Stink farts can be avoided very easily
Who eats, digests and has to fart at some point. It often stinks. But that can be prevented - even without having to go without cheese, eggs or meat.
If there is rumbling in the intestine, flatulence is not far off. This is due to the bacteria in the intestinal flora, which break down the food pulp.
They convert the carbohydrates it contains into hydrogen, carbon dioxide and methane. These substances sometimes escape loudly, but do not smell. The intestinal bacteria also break down the proteins. And they give the escaping gases the foul smell of foul-smelling hydrogen sulfide.
Less farting despite proteins
This is uncomfortable for the person concerned, but also for those around him. In addition, the musty-smelling farts are suspected of increasing the risk of chronic intestinal diseases or even colon cancer.
That is why researchers at Monash University in Melbourne have investigated how the formation of hydrogen sulfide in food can be restricted - without having to completely do without protein-containing products such as cheese, eggs or meat.

Amino acid as a hydrogen sulfide booster
To this end, Chu Yao's team examined the feces of seven healthy adults and added certain amounts of cysteine to the samples in the laboratory. This sulphurous amino acid is found in high concentrations in protein-rich foods.
The re-analysis of the stool samples showed that the intestinal bacteria contained therein now produced seven times the amount of hydrogen sulfide compared to before.
Something can be done about that
The researchers also found that the whole thing is also reversible. By adding slowly degradable carbohydrates. This significantly reduced hydrogen sulfide emissions.
Starch, which is found in potatoes, bananas and cereal products, turned out to be a particularly effective substance. But so-called fructans, i.e. multiple sugars found in wheat, artichokes and asparagus, among other things, worked wonders. The fabrics reduced bad smells by 75 percent.
New nutritional advice
If the result is confirmed in a study with humans, it will overturn some dietary suggestions, comments the "New Scientist" on the results presented at the annual meeting of the Gastroenterological Society of Australia.
So far, people who suffer from excessive, odor-intensive flatulence - so-called meteorism - have been advised to avoid foods rich in fiber. This could change now.
If you eat the right thing, you smell less. (Video: Youtube / New Scientist)
