People Fall Into Three Categories Of Gut Microbiota : Implications for Nutrient and Medicine Uptake

by an international consortium of scientists including Jeroen Raes, of the VIB and Vrije Universiteit Brussel, published in Nature. Metagenomics is the study of the genetic material of complete ecosystems, in this case the human gut.

“The three gut types can explain why the uptake of medicines and nutrients varies from person to person,” says bioinformatician Jeroen Raes of the VIB and Vrije Universiteit Brussel, one of the two lead researchers in the study. “This knowledge could form the basis of personalized therapies. Treatments and doses could be determined on the basis of the gut type of the patient.” Improved knowledge of the gut types could also lead to other medical applications, such as the early diagnosis of intestinal cancer, Crohn’s disease and the adverse effects of obesity..

While studies have shown that probiotics may help people with a host of digestive conditions, their benefit hasn’t been proven in people with severely compromised immune systems, the association says.

On the other hand, probiotics may help treat people with:

  • Irritable bowel syndrome (IBS).
  • Inflammatory bowel disease (IBD).
  • Diarrhea caused by infection with a virus, bacteria or parasite.
  • Diarrhea caused by taking antibiotics.
