There is no evidence that PUFA supplementation in infancy has an effect on infant or childhood allergy , asthma , dermatitis/eczema or food allergy .
However , the quality of evidence was very low .
There was insufficient evidence to determine an effect on allergic rhinitis
BACKGROUND Early dietary intakes may influence the development of allergic disease .
It is important to determine if dietary polyunsaturated fatty acids ( PUFAs ) given as supplements or added to infant formula prevent the development of allergy .
OBJECTIVES To determine the effect of higher PUFA intake during infancy to prevent allergic disease .
The introduction of allergenic foods and the development of reported wheezing and eczema in childhood: the Generation R study.
OBJECTIVE To examine whether the timing of introduction of the allergenic foods cow 's milk , hen 's egg , peanuts , tree nuts , soy , and gluten is associated with  eczema and wheezing in children 4 years of age or younger . DESIGN Population -based prospect i ve cohort study from fetal life until young adulthood . SETTING Rotterdam , the Netherl and s , from April 2002 through January 2006 . PARTICIPANTS A total of 6905 preschool children participating in the Generation R study . MAIN EXPOSURE Timing of introduction of cow 's milk , hen 's egg , peanuts , tree nuts , soy , and gluten collected by question naires at 6 and 12 months of age . MAIN OUTCOME MEASURES Information on the outcomes eczema and wheezing were obtained by questions from the age-adapted version of the " International Study of Asthma and Allergies in Childhood " core question naire and question naire data on parentally reported physician diagnosis for eczema . RESULTS Of 6905 children ,  wheezing was reported in 31 % at age 2 years and in 14 % at ages 3 and 4 years . Eczema was reported in 38 % , 20 % , and 18 % of children at the ages of 2 , 3 , and 4 years , respectively . The introduction of cow 's milk , hen 's egg , peanuts , tree nuts , soy , and gluten before the age of 6 months was not significantly associated with eczema or wheezing at any age after adjustment for potential confounders ( P > .10 for all comparisons ) . The results did not alter after stratification according to the child 's history of cow 's milk allergy and parental history of atopy . CONCLUSION This study does not support the recommendation for delayed introduction of allergenic foods after age 6 months for the prevention of eczema and wheezing
