The : The gas you pass is manufactured by the bacteria that live in your colon when they consume food substances that are not completely absorbed in the small bowel. The gas is produced primarily from incompletely absorbed carbohydrates. The undigestible fiber found in the fruits and vegetables are a wonderful feast for the bacteria resulting in an increased production of gas. Interestingly, the type of gasses we pas are partly due to the very specific mixture of bacteria that populate each person's colon. This is different from person to person so that the same foods don't necessarily cause the same odor in different people. An increase in gas after a change in diet is not necessarily a sign of illness. You can test this by seeing if the gas subsides by going back to your prior diet. It is possible that the gas represents a more specific problem absorbing certain types of foods (one example is lactose intolerance); you should talk to your physician to make sure.

Sulfur rich foods: The more sulfur rich the foods you eat, the more your farts will stink because bacteria will generate sulfides and mercaptans as they break down the nutrients.
