Sometimes this gas is produced in such huge quantities that the sulfide oxidase enzyme in the wall
of the gut is not able to oxidize all
of it and convert it to thiosulfate. This
gas has a smell of rotten eggs. You need to cut down food items that contain sulfites. Most of this gas comes from sulfites a person consumes, which is a part of all preservatives. Sulfites are present in all juices, molasses, yellow dye in ready made food stuffs, and red wine.
