Weak Gut Causes Type 2 Diabetes, Obesity- Study Finds

obesity-kidA new study has found that people who have weak gut due to a poor dietary diversity are vulnerable to common ailments, including Type-2 diabetes, obesity and inflammatory bowel disease.

The study by researchers from Pennington Biomedical Research Centre in US has attributed the reduced richness of gut microbiota or the bacteria that lives in human gut to the reduction in diversity of foods that we consume.

Dietary diversity, which can be defined as number of unique food items consumed over a given period of time, keep the bacteria ecosystem in our stomach in tact, hence helps us fight against the diseases.

The researchers, therefore, emphasised on a balanced, diversified diet in order to get a strong gut health. According to them, many of this century’s common pathologies, including Type-2 diabetes, obesity and inflammatory bowel disease, occur due to reduced microbiotic richness.

“Healthy individuals posses a diverse gut microbiota but a reduced microbiotic richness gives rise to Type 2 diabetes, obesity and inflammatory bowel disease,” researchers noted in their paper published in the journal Molecular Metabolism.

For poor dietary diversity, experts have blamed changes in farming practices in the last half-century that has led to reduced agricultural and dietary diversity.

Human gut microbiota works as an effective endocrine organ, which metabolise specific nutrients from the foods and generate particular substances that are metabolic signals in the host.

In healthy individuals, the richness of microbiota species indicate diverse gut microbiome. On the other hand, any loss in species diversity is commonly found in a number of diseased conditions.

Undigested or partially digested food, as well as drugs and dietary supplements too can confer abundance of energy to the microbiome. This energy is converted into new molecules by every microbiotic species in the biome and the abundance of molecules might send messages to the host’s physiological systems. The increased variations indicates the increased diversity of the microbiome, making it more adaptable to perturbations and produce an increased range of physiological responses, the researchers noted.

“The greater the repertoire of signals, the more likely is the ability to maintain homeostasis when dietary intake is perturbed,” researchers said.

So, if you think that slim and trim people can’t get struck by diabetes or become obese then you should think again, as the fresh findings have concluded that it is a weak ecosystem of bacteria in human gut which causes type 2 diabetes or obesity.

The findings are published in the journal Molecular Metabolism.
