He has published over 300 papers and is particularly known for his pioneering work on the importance of colonic bacteria to health and the role of carbohydrates, especially resistant starch and dietary fibre, as substrates for fermentation and the metabolism of short chain fatty acids. In 1998, he moved to the University of Dundee. John Cummings has served on many national, European and international bodies concerned with diet and health. He has been a member of the WHO Nutrition Guidelines Advisory Group since 2009. In 1993 Professor Cummings was awarded the Caroline Walker Science Prize and the Cleave Trophy of the McCarrison Society in recognition of his work on public health aspects of diet.
