29 Oct 2018 --- The gut microbiota has the ability to affect how cells respond to insulin, and can thus contribute to Type 2 diabetes, according to a study published in the journal Cell. According to the study authors, the findings show how important the interaction between gut microbiota and diet is to understand the metabolism in health and disease. During recent years, the gut microbiota has been associated with health and several disease conditions. However, only a few studies have investigated whether an altered gut microbiota can directly affect disease.
