A recent study, led by Dr. Deanna L. Gibson from the Department of Biology at the University of British Columbia (Canada), has found that cardiorespiratory fitness is correlated with increased microbial diversity and increased production of faecal butyrate in healthy humans.

It has been previously reported that the gut microbiota could be involved in the pathogenesis of metabolic diseases such as diabetes. A recent study, led by Dr. Wolfgang zu Castell from the Scientific Computing Research Unit at Helmholtz Zentrum München in Munich (Germany) has found that butyrate may have a protective effect in the pathogenesis of type 1 diabetes.
