Having spent her early years in and out of ICU units, suffering from chronic illness, and her 20s battling an ever-escalating list of ailments, Creed found herself on dozens of medications, seeing innumerable doctors and specialists, and undergoing endless tests and thirteen sinus operations. After decades of searching for a stable sense of medical wellbeing, it wasn't until Dr Robbie Simons gave Creed back her health and her life that she decided to study the subject further. She went on to achieve a postgraduate diploma in Clinical Nutrition and later studied Functional Medicine. Sally-Ann Creed is the author of nine books, including the bestselling Let Food Be Your Medicine, which is still viewed as a classic today.
