BEHOLD, the most fragrant news you'll read all day.
Gut microbiome expert Dr Maximilienne Allaart has lifted the lid on the science of flatulence, with a veritable treasure trove of fun fart facts.
Writing in The Conversation, she notes that the link between what you eat, how much gas you create and how the gas smells is due to the gut microbiome.
It may surprise people - at least those who don't socialise with body builders - to learn that animal protein is one of the biggest, smelliest culprits.
This is down to hydrogen sulphide, which is produced if your food contains sulphur.
"Sulphur is typically found in the amino acids cysteine and methionine, which are part of proteins," wrote Dr Allaart.
These amino acids tend to be higher in animal proteins, such as eggs and red meat, than in plant proteins, and too much is not a good thing.
Vegetable fart smells, on the other hand, are down to volatile fatty acids produced when the body breaks down fibrous food.
Another fascinating learning is that you produce your own signature fart scent.
"Your gut is a complex jungle of interactions between the body, its microbes and your food.
"And just as each person's microbiome is unique, so is the scent of the gas it produces."
The good news is that there are foods that can make your farts less smelly, including rice, corn, potato, quinoa, skinless chicken, turkey and fish.
