In the randomised controlled PINGU intervention trial, we tested the effects of complementary foods with different contents of alpha-linolenic acid (ALA) and docosahexaenoic acid (DHA) on term infant LC-PUFA status. Methods Healthy infants born at term were randomised to receive from the introduction of complementary feeding at the age of 4 to 6 months until age of 10 months ready-made complementary meals either with ALA-rich rapeseed oil (intervention group (IG)-R), with salmon twice weekly to provide preformed DHA (IG-F), or with linoleic acid-rich corn oil (control group, CG). Fatty acid composition was assessed in erythrocyte (RBC) and plasma glycerophospholipids. Results Complete data of fatty acids in RBC (plasma) were available from 158 (155) infants. After intervention, infants assigned to IG-F showed higher RBC and plasma percentages of eicosapentaenoic acid (EPA), DHA, and total n-3 LC-PUFA than CG (each p < 0.001). In IG-R, levels of ALA and the ratio of ALA to LA in plasma and RBC (all p < 0.0001) as well as RBC-EPA (p < 0.0001) were higher than in CG, while DHA levels did not differ between IG-R and CG. Conclusions Regular fish consumption during complementary feeding enhances infant EPA and DHA status. The usage of rapeseed oil in small amounts concordant with EU-law for commercial meals enhances endogenic EPA-synthesis, but does not affect DHA status. Provision of oily fish with complementary feeds is advisable to prevent a decline of DHA status.

Copolymers with different ratios of these monomers were prepared via two different routes (ADMET and thiol-ene) and studied in detail. Both monomer and polymer synthesis were optimized in order to achieve high yielding synthetic procedures that meet the requirements of green chemistry. Some thermal properties of the resulting copolymer series were then studied and correlated to the co-monomer composition.}, language = {en} }
