Omega-3 fatty acids are a major component of neural membranes. They are essential nutrients for normal biochemical development of the brain and retina and may affect behavior. In our studies of long-term dietary omega-3 fatty acid deficiency, we have found a new effect of this deficiency in rhesus monkeys. Deficient monkeys visited the home cage drinking spout more frequently than controls (Experiment 1), and drank more water over 24 hours (Experiment 2). The increase in intake was mirrored by increased combined output of urine + feces over 24 hours (Experiment 3), and was not due to spillage (Experiment 4). The dietary deficiency greatly reduced omega-3 fatty acids in red blood cells but did not affect serum electrolyte levels. The changes in fluid intake and output may be related to direct or indirect effects on central or peripheral control mechanisms for drinking or excretion, which may be mediated by altered composition of neural or other membranes or changes in eicosanoid metabolism.
