Food allergies for children have been on the rise in Australia over the last decade. After a frightening experience with his own daughter, Paediatric Gastroenterologist Dr Vincent Ho took a closer look at the impact of gut health on allergy prevention. His book The Healthy Baby Gut Guidelooks at all the ways parents can help their children develop a healthy gut, which in turn can help prevent food allergies. Vincent explains the latest research on allergy prevention through pregnancy, breastfeeding and starting solids.
