AUTHORS ' CONCLUSIONS Feeding with a soy formula can not be recommended for prevention of allergy or food intolerance in infants at high risk of allergy or food intolerance .
BACKGROUND Allergies and food reactions in infants and children are common and may be associated with a variety of foods including adapted cow 's milk formula .
Soy based formulas have been used to treat infants with allergy or food intolerance .
However , it is unclear whether they can help prevent allergy and food intolerance in infants without clinical evidence of allergy or food intolerance .
OBJECTIVES To determine the effect of feeding adapted soy formula compared to human milk , cow 's milk formula or a hydrolysed protein formula on preventing allergy or food intolerance in infants without clinical evidence of allergy or food intolerance .
Effect of allergen avoidance in infancy on allergic manifestations at age two years.
BACKGROUND One hundred twenty children , identified before birth as being at high risk for atopy , were prenatally assigned to prophylactic or control groups . METHODS The infants in the prophylactic group either received breast milk from mothers on an exclusion diet or an extensively hydrolyzed formula . Their bedrooms and living rooms were treated repeatedly with an acaricide , and they used polyvinyl-covered mattresses with vented head areas . The infants in the control group were fed conventionally , and no environmental control was recommended . RESULTS A significant advantage , first demonstrated at 1 year of age , persists for children in the prophylactic group . They have less of any allergy or eczema , but the reduced prevalence of asthma is no longer significant . Only three children in the prophylactic group had positive skin prick test results compared with 16 in the control group , suggesting a significant reduction in sensitization . CONCLUSION A dual approach to allergen avoidance , focusing on foods and aeroallergens , appears to be beneficial in selected high-risk infants . Avoidance of potent allergens in early life increases the threshold for sensitization in these high-risk infants . Whether sensitization has been avoided or merely deferred has yet to be proved
