How are Gut Microbes involved in Food Sensitivity?

Involvement of Gut microbes in food sensitivity

There is a growing body of evidence indicating gut microbes’ complex role in a number of GI disorders including IBS. Adverse food events (flareups or symptoms after ingesting certain foods) could be related to changes in gut microbiota.

GI bacteria responsible for fermentation of poorly absorbed fermentable carbohydrates may be altered in people with IBS resulting in looser stools and increased gas production.

Disruption in an individual’s gut microbiota may lead to a change in how the immune system reacts to certain foods. Disruptions can be caused by:

  • Environmental triggers (e.g., food-borne illness)
  • Genetics
  • Lack of microbial diversity
  • Pathogens (e.g., harmful bacteria)
  • Decrease in useful bacteria
