07 Aug 2018 --- Montmorency tart cherries may play a role in improving gut health, suggests a first-of-its-kind human trial of nine adults combined with a parallel laboratory study published in the Journal of Nutritional Biochemistry. An international team of scientists found that Montmorency tart cherries helped to positively impact the gut microbiome – a collection of trillions of bacteria and other microbes that live in the intestinal tract. The study has been highlighted by the trade association The Cherry Marketing Institute.
