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 .
Visual-acuity development in healthy preterm infants: effect of marine-oil supplementation.
Docosahexaenoic acid ( DHA ; 22:6n-3 ) is important for normal visual development . We hypothesized that preterm infants fed formulas with marine oil as a source of DHA  would have better visual acuity than infants fed formulas without marine oil  , as measured by the Teller Acuity Card procedure . Marine oil ( P < 0.001 ) and age ( P < 0.0001 ) influenced visual acuity , by repeated- measures analysis of variance ( ANOVA ) corrected for the effect of subject . Marine-oil-supplemented infants had better visual acuity than those fed st and ard formulas at 2 and 4 mo of age , by Fishers ' least-squares difference ( LSD ) . Acuity of both dietary groups improved through 6.5 mo of age , then plateaued . Through 4 mo of age , acuity was inversely related to oxygen supplementation ( log10 h ) and positively related to DHA status , by general-linear-models ( GLM ) analysis . After 4 mo of age , birth weight and gestational age were the only variables consistently related to visual acuity by GLM . We conclude that marine-oil-supplemented formula improved visual acuity of preterm infants through 4 mo of age by improving DHA status
