Fish Oil Diet

The purpose of this study was to investigate the effect of long-term supplementation with dietary lipids on growth and fatty acid composition of rabbit’s brain. Soybean oil, fish oil, sesame oil, docosahexaenoic acid and arachidonic acid were fed to weanling rabbits for 100 days. The rabbits were decapitated and brain sample was removed, homogenized and fatty acid concentration was measured by gas chromatography. Dietary lipids had a distinct effect on growth rate only in males. Rabbits fed the fish oil diet showed the highest total w-3 fatty acids and lowest w-6/w-3 ratios. Rabbits fed the DHA diet had highest total saturated fatty acids and lowest values of total MUFA, total PUFA, total w-6, and total w-3 in females. This study shows that w-6/w-3 ratios have tremendous effect on the fatty acid composition of rabbit’s brain. Effect of treatment was not significant among different gender except for total saturated, ARA, C20:1 and C16:0. FO, DHA and DHA+ARA groups showed the w-6/w-3 ratios within the recommended range. This study shows that fatty acid composition of brain can be modulated by dietary lipids and long-term supplementation of dietary lipids especially fish oil (FO) has very good effect on the fatty acid composition of rabbit’s brain.

Fish Oil Diet

Very long-chain n-3 PUFA from fish are suggested to play a role in the development of the brain. Fish oil feeding results in higher proportions of n-3 PUFA in the brains of newborn piglets. However, the effect of fish oil on the fatty acid composition of specific cerebral brain lobes in juvenile pigs is largely uninvestigated. This study examined the effect of a fish oil diet on the fatty acid composition of the frontal, parietal, temporal and occipital brain lobes in juvenile pigs (7 weeks old). Pigs were randomly allocated to a semipurified pig diet containing either 4 % (w/w) fish oil (n 19) or 4 % (w/w) high-oleic acid sunflower oil (HOSF diet, n 18) for a period of 8 weeks. The fish oil diet resulted in significantly higher proportions (%) of DHA in the frontal (10·6 (sd1·2)), parietal (10·2 (sd1·5)) and occipital brain lobes (9·9 (sd 1·3)), but not in the temporal lobe (7·7 (sd1·6)), compared with pigs fed the HOSF diet (frontal lobe, 7·5 (sd1·0); parietal lobe, 8·1 (sd 1·3); occipital lobe, 7·3 (sd1·2), temporal lobe, 6·6 (sd1·2). Moreover, the proportion of DHA was significantly lower in the temporal lobe compared with the frontal, parietal and occipital brain lobes in pigs fed a fish oil diet. In conclusion, the brains of juvenile pigs appear to be responsive to dietary fish oil, although the temporal brain lobe is less responsive compared with the other three brain lobes. The functional consequences of these differences are a challenging focus for future investigation.
