Feeding soya-based formula as opposed to st and ard cow 's milk formula did not reduce the risk of having asthma or wheeze at any age .
In infants with at least one first degree relative with atopy , hydrolysed formula for a minimum of 4 months combined with dietary restrictions and environment measures may reduce the risk of developing asthma or wheeze in the first year of life .
There is insufficient evidence to suggest that soya-based milk formula has any benefit
BACKGROUND In infants with a family history of atopy , food allergen avoidance has been advocated as means of preventing the development of atopic disease when breast-feeding is not possible or supplemental feeding is needed .
Most infant formulas are based on cow 's milk protein .
Alternative choices include soya based and hydrolysed cows milk formulas .
OBJECTIVES To estimate the effect of dietary avoidance of cow 's milk protein on the development of asthma or wheeze in children .
Effect of combined maternal and infant food-allergen avoidance on development of atopy in early infancy: a randomized study.
The effect of maternal and infant avoidance of allergenic foods on food allergy was examined in a prenatally r and omized , controlled trial of infants of atopic parents . The diet of the prophylactic-treated group ( N = 103 ) included ( 1 ) maternal avoidance of cow 's milk , egg , and peanut during the third trimester of pregnancy and lactation and ( 2 ) infant use of casein hydrolysate ( Nutramigen ) for supplementation or weaning , and avoidance of solid foods for 6 months ; cow 's milk , corn , soy , citrus , and wheat , for 12 months ; and egg , peanut , and fish , for 24 months . In the control group ( N = 185 ) , mothers had unrestricted diets , and infants followed American Academy of Pediatrics feeding guidelines . The cumulative prevalence of atopy was lower at 12 months in the prophylactic-treated ( 16.2 % ) compared to the control ( 27.1 % ) group ( p = 0.039 ) , result ing from reduced food-associated atopic dermatitis , urticaria and /or gastrointestinal disease by 12 months ( 5.1 % versus 16.4 % ; p = 0.007 ) , and any positive food skin test by 24 months ( 16.5 % versus 29.4 % ; p = 0.019 ) , caused primarily by fewer positive milk skin tests ( 1 % versus 12.4 % ; p = 0.001 ) . The prevalences of allergic rhinitis , asthma , and inhalant skin tests were unaffected . Serum IgE levels in the prophylactic-treated group were marginally lower only at 4 months . Thus , reduced exposure of infants to allergenic foods appeared to reduce food sensitization and allergy primarily during the first year of life
