Please note this page needs updating for current guidelines around preventing food allergy and introducing potential allergenic foods. See this excerpt in the meantime.
On this page I’m going to attempt to pull together all of the information we have on diet, allergy, intolerances and gastric reflux disease. Some infants presenting with signs of gastric reflux may have their symptoms relieved entirely by changing their diet. It is my experience that if there is a food allergy present, it is impossible to gain good control of gastric reflux disease with medication.
If there is a history of any allergy (including hay fever) in either parent there is an increased risk that their children will have allergies and if both parents have allergies this is further increased to 50-60%. Even in a non-allergic family there is a 5-15% risk of allergies.
Studies have shown that about one third of infants with gastric reflux disease will have a cow’s milk protein allergy or intolerance.1 Skin prick or blood RAST testing will often not pick up this “gastrointestinal” food allergy as it may be a delayed reaction, and is best diagnosed by an elimination diet and challenge. This involves removing dairy from the mother’s diet if breastfed or a trial of a non-cow’s milk based formula. A trial of a dairy free diet is in fact the first recommendation on our treatment guidelines: GORD and Managing Uncomplicated Reflux. Some parents have found that unproven forms of testing such as Kinesiology have helped them to remove offending foods. GRSNNZ doesn’t endorse these and would recommend that limited diets also be supervised by a dietician, that a medically qualified health professional (paediatrician, allergist, immunologist etc) be involved and if appropriate the foods be challenged after a suitable time lapse.
Cow’s milk protein allergy should not be confused with lactose intolerance. Breast milk always contains lactose even if the mother is on a strict dairy free, lactose free diet so a baby who responds to a change in their mother’s diet, does not have a lactose intolerance. Please contact us if you would like an article on Lactose Intolerance vs. Milk Protein Allergy.
For more information please see: Food and Reflux
Solids should be introduced around six months of age.2 In addition to this, it is our experience that a number of infants with GOR do not cope well with the introduction of gluten (wheat, barley, rye and oat products) and may develop an intolerance to this. Good first foods that are less likely to cause a reaction include plain baby rice (please check the ingredients as some brands of baby cereal contain milk products), kumara and pumpkin. Taking the introduction of solids slowly should allow you to work out which foods cause problems.
