Abstract/OtherAbstract:
Both animal and human studies demonstrate that the docosahexaenoic acid (DHA) content of plasma and/or tissue lipids is increased during pregnancy. We hypothesised that increasing the α-linolenic acid (ALA) or longer chain (n-3) PUFA content of the maternal diet during pregnancy influences fetal fatty acid composition and the fetal immune system. Pregnant rats were fed a low-fat (LF) soybean oil diet, or high-fat (HF) soybean, linseed, salmon or sunflower oil diets from conception to 20d gestation. The ALA-rich Linseed-HF diet resulted in an equivalent eicosapentaenoic acid (EPA) status in fetal immune tissues and an equivalent DHA status in the fetal brain to that achieved with the Salmon-HF diet. An (n-3) rich maternal diet during pregnancy associated with the highest expression of CD3 (Salmon-HF) and CD8 (Linseed-HF and Salmon-HF) on fetal thymic CD3(+)CD8(+) cells. The Linseed-HF diet resulted in the highest proportion of CD161(+) cells within the fetal thymus, which correlated with the production of IL-4. These data indicate that dietary ALA supplementation may confer some of the benefits of LC (n-3) PUFA during pregnancy. This should be examined in suitably designed human studies.
