Farts, while natural, can be embarrassing, especially when they are particularly odorous. An expert discusses how the smell of farts can be linked to gut health and dietary choices. The process begins in the gut when bacteria break down food into gases. While most gases are odorless, hydrogen sulfide is responsible for that familiar rotten smell, produced from sulfur-containing foods. Foods like eggs, red meat, and even artificial sweeteners can amplify this odor, highlighting the connection between diet and gastrointestinal health.
A fart has to be one of the most mortifying bodily functions. ... Now, an expert has lifted the lid on why some farts smell worse than others and how the stench could provide clues about what's going on in your gut.
There's a correlation between what you eat, how much gas your belly creates and how the gas smells. This is because each food affects your body and your gut microbes differently.
Sulphur is typically found in the amino acids cysteine and methionine, which are part of proteins. There are generally higher levels of these amino acids in animal proteins - such as eggs and red meat.
Artificial sweeteners have also been linked to smelly farts, indicating that diet choices can greatly influence the odor of gas.
