"Probably the best example of this interaction is the discovery that IBS symptoms develop in up to 10 percent of previously healthy subjects after a single episode of gastroenteritis caused by an infection through bacterial pathogens like Salmonella, Shighella or Campylobacter, which can severely disrupt the microbiota balance," says Prof. Barbara. An additional problem results from the fact that not only infections, but also the antibiotics that are used as a remedy, may increase the risk for IBS, as they, too, can alter the gut microbiota in a negative way.
Nutrition is key
Another important factor is nutrition. Food that is rich in carbohydrates, particularly fiber, tends to produce larger amounts of gas than a diet without these ingredients. In some individuals, this might lead to repeated bloating and flatulence. The potentially negative impact of this kind of nutrition applies in particular to individuals who already suffer from IBS. Recent studies show that such a "flatulogenic" diet (for example, bread, cereals and pastries made of whole wheat, and beans, soy beans, corn, peas, Brussels' sprouts, cauliflower, broccoli, cabbage, celery, onions, leek, garlic, artichokes, figs, peaches, grapes and prunes) induces profound changes in the microbiota of IBS patients, thus prolonging and increasing the symptoms. However, at the same time, the gut microbiota
