                                According to a 2022 study in *Nature Metabolism*, hydrogen sulphide, produced by gut microbes, can interact with other chemicals in the gut, with potential consequences for human health. This foul-smelling gas is the result of intestinal bacteria breaking down sulfur-containing compounds found in many common foods.
