"I have read ten to fifteen books on the gut, both by doctors and non-doctors. Yours is the best!”—Eva Leander-Fryk, specialist in General Medicine and Geriatrics “Soki Choi's book Kombucha and Kimchi is a very fact-packed book with an impressive reference list for each chapter. In summary, this book is very readable for ‘nerds’ regarding food, medicine, microbiology, and veterinary medicine."—Torkel Wadström, professor emeritus in medical microbiology "In a playful and easy-to-understand way, Soki makes new, cutting-edge research understandable for both the doctor and the layman. Soki's passion for public health also shines through the whole book. Highly recommended."—Cecilia Tibell, doctor, Internal medicine, endocrinology, functional medicine
