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 .
Modification of dietary polyunsaturated fatty acids via complementary food enhances n-3 long-chain polyunsaturated fatty acid synthesis in healthy infants: a double blinded randomised controlled trial
Objective : To study the effect of modified polyunsaturated fatty acid ( PUFA ) profiles of complementary food on long-chain ( LC ) PUFA composition in healthy infants . Design : Double blinded , r and omised , controlled intervention trial . Setting : Dortmund , Germany . Patients : Free-living sample of healthy term infants . Methods : Participants were r and omly assigned within the first 2 months of life . During the intervention period from 4 to 10 months , the control group ( n = 53 ) received commercial complementary meals with corn oil ( 3.4 g/meal ) rich in n-6 linoleic acid ( LA ) , the intervention group ( n = 49 ) received the same meals with rapeseed oil ( 1.6 g/meal ) rich in n-3 alpha-linolenic acid ( ALA ) .  Fatty acid intake was assessed from dietary records throughout the intervention period . Fatty acid proportions ( % of total fatty acid ) in total plasma were analysed before and after the intervention . Results : Plasma fatty acid profiles did not differ between the intervention and control groups before the intervention . During the intervention , the only difference in fatty acid intake between the intervention and control groups was a higher intake of ALA in the intervention group , 21 % deriving from study food and a lower ratio of LA/ALA ( 10.7 vs 14.8 ) . At the end of the intervention , the plasma proportions of total n-3 fatty acids and of n-3 LC-PUFA , but not of ALA , were higher and the ratios of n-6/n-3 fatty acids were lower in the intervention group . Conclusions : Feasible dietary modifications of the precursor fatty acid profile via n-3 PUFA-rich vegetable oil favoured n-3 LC-PUFA synthesis in the complementary feeding period when LC-PUFA intake from breast milk and formula is decreasing
