Gut Feelings: The Microbiome and Our Health by Alessio Fasano and Susie Flaherty reveals how understanding this alien inner world will make it possible to target medicines to an individual s needs at the molecular level.   New Scientist

"Gut Feelings is a detailed and scientifically rigorous survey... [Fasano and Flaherty] scrupulously assess the many studies on the microbiome and human health with an echoing drumbeat of conditional terms, cautioning the reader that research in rodents may not be replicable in humans,
and that correlations found in human populations or individual patients ultimately may not prove causative. Such caveats distinguish this book from popular works on nutrition that make exaggerated claims about how manipulating the microbiome can treat a variety of illnesses. Gut Feelings, by contrast, gives readers a clearer sense of the current state of medical knowledge."  Jerome Groopman, The New York Review of Books
