Dr John Sinn 

MBBS (Syd), M Med (CEpi) DCH, Dip Paed, FRACP

Paediatric Allergist and Neonatologist


Dr John Sinn is a paediatric allergist for infants and children at The Paediatric Centre. Dr Sinn's special interest is to decrease food allergy sensitivity via step ladder approach. Common allergens like egg, cow's milk and all type of nuts can be modified by food preparation techniques and are used to develop tolerance  with eventual  aim of desensitisation. Prevention and treating eczema is the first step in the management of allergies. Aeroallergens like dust mite, grasses and pollen often exacerbate eczema and can be treated with immunotherapy. 


Dr John Sinn is also a Consultant Neonatologist at Royal North Shore Hospital.  He is a full member of ASCIA and has been on policy boards of RACP, ASCIA, EAACI, FSANZ, PSANZ and NHMRC.  He has extensive publications in areas of allergy prevention, food intolerances, cows milk allergy, probiotics and prebiotics, and immunisations. He has written national policies on cow's milk intolerance and food allergy prevention strategies.  He has written more than 10 Cochrane reviews which are the major reference points for probiotics, prebiotics, allergy prevention, hydrolysed protein, iodine, soy, amino acid, ADHD and omega 3.  There are more than 2700 publications that has cited Dr Sinn's research papers. He is an international and national invited speaker, presenting regularly on nutrition, probiotics, microbiome and allergy. Internationally he has been invited to speak at government levels from countries like China, Hong Kong, India, Vietnam and Malaysia. He is an author on the guideline for the first 1000 days which is in every new mother's information pack in Australia and New Zealand.
