Chris and Xand continue their conversation about fibre with Dr Deirdre Tobias, an obesity and nutritional epidemiologist at the Brigham and Women's Hospital and Harvard Medical School in Boston, USA.

Together, they dig further into the relationship between our fibre intake and our microbiome. Plus, they delve into some of the socioeconomic aspects of increasing our intake of fibre.
