Obesity and gut bacteria linked together
There have been many studies now showing that your gut bacteria population influences your weight dramatically. Healthy rural African children have a very different gut bacteria profile than do overweight Western children. The thing that influences your gut bacteria more than any other single thing is, of course, your diet.
The latest research
In 2008 The National Institutes of Health Human Microbiome Project started funding varied ‘health and the human gut’ studies around the world. So far they have discovered links between the microorganisms in the gut and flu in young children, digestive disorders of all kinds, skin problems and cancer. In the 310-strong Amish research, University of Maryland School of Medicine scientists identified one of three standard communities of bacteria that were common to all. However the people with high blood pressure, insulin resistance, metabolic syndrome and obesity also had 26 other rare intestinal bacteria linked to insulin resistance, high blood pressure, cholesterol imbalance and blood sugar levels.
Dr. Alan R. Shuldiner, an associate dean in personalized and genomic medicine at the University of Maryland School of Medicine says “The big question is how these microorganisms affect health and disease in humans. It may have something to do with genes, or various lifestyle factors and the environment”. Lita Proctor, coordinator of the NIH Human Microbiome Project suggested that “perhaps the metabolic functions of the microorganisms somehow influence the metabolic functions of the human body”.
