    TITLE ESSENTIALITY OF DIETARY OMEGA 3 FATTY ACIDS
    FUTURE YEARS 1
    ABSTRACT:

    The essentiality of dietary omega-3 fatty acids remains an unresolved issuein human nutrition. The high content of docosahexaenoic acid (22:6omega3or DHA) in the phospholipids of the retina and cerebral cortex suggestsan important role in photoreceptor and neuronal membrane functions. We areinvestigating the effects of omega-3 fatty acid deprivation in rhesus monkeysduring prenatal and postnatal development. DHA levels in retinal and brainphospholipids were greatly reduced, visual acuity development was delayed,retinal function as measured with the electroretinogram (ERG) was abnormal,and several behavioral changes have been identified. Effects on the ERGwere not reversible by refeeding with fish oil or pure DHA at 10 monthsor older. We propose to complete two studies which are now in progress toaddress several remaining critical questions about the effects of dietaryomega-3 fatty acid deficiency and supplementation:

    1. What form of dietary omega-3 fatty acids is optimal for functional development?Should infants receive preformed DHA, arachidonic acid and the other very-long-chainessential fatty acids present in human milk? We are comparing several aspectsof development in rhesus infants receiving a standard formula providinglinolenic acid and in those receiving a formula with fatty acid compositionsimulating primate milk.

    2. Can effects of low dietary omega-3 fatty acids be separated from thoseof high omega-6 fatty acids? In the current studies, omega-3 fatty aciddeficient diets are matched to control diets in their level of omega-6 fattyacids.

    3. Does omega-3 fatty acid deficiency affect other aspects of sensory function,and does it affect complex behaviors and cognitive abilities? We have newevidence for effects on behavioral reactivity and infant visual informationprocessing, and we are exploring several other aspects of behavior and cognitivefunction in both infants and adults.

    4. How do deficiency and supplementation alter phospholipid molecular speciescomposition as well as the fatty acid composition of the retina, cerebralcortex and other tissues? Are there changes in the density and morphologyof synapses in the cerebral cortex or in levels of key neurotransmittersand their receptors?

    These studies will help to determine nutritional needs for omega-3 fattyacids during development, and the results will have important implicationsfor the composition of human infant formulas as well as for the optimumdiets of pregnant and lactating women. These studies will also help to definethe roles of these fatty acids in neural, sensory and behavioral development.
