Scientist Giulia Enders shows that rather than the utilitarian and - let's be honest - somewhat embarrassing body part we imagine it to be, the gut is one of the most complex, important, and even wondrous parts of our anatomy. Beginning with the personal experience of illness that inspired her research, and going on to explain everything from the basics of nutrient absorption to the latest science linking bowel bacteria with mental disorders, this is an entertaining handbook for those looking to improve their health and deepen their understanding of their body.
