'Being identical twin sisters, we have a passion (teetering on obsession) for finding out what's different about us. Twins are a great constant for medical research and we became the 'chief guinea pigs' for the British Gut project where we discovered that despite us having 100% the same DNA our guts have only 40% the same microbiota, which could explain why our bodies behave so differently. Thus our 'gut journey' began.'
