Abstract :

Introduction & Objective: Polyunsaturated Fatty Acids (PUFA) long chain, especially n-6 Arachidonic Acid (ARA) and the Docosahexaenoic acid n-3 (DHA) are important in the development and maturation of the newborn brain system. Their content in Human Milk (HM) varies with the mother’s diet. Supplementation with n-3 PUFA (α-Linolenic Acid, ALA) could increase the concentration of DHA in milk. The objective of the study was to assess the composition of breast milk after 15 days supplementation of n-3 PUFAs. Material & Method: Multicentric randomized trial (Human milk banks: Bordeaux, Lyon, Paris, Montpellier), according to a factorial design 4 groups of 20 women each. From D0 to D15, same diet (olive oil) and from D15 to D30 diets were: Olive oil (O); margarine rich in n-3 PUFA (M); rapeseed oil (C) and M+C (MC). Diets 1-4 provided an increasing ALA intake. In the 4 groups, there was constant supply of DHA (500 mg/d, 170 g Mackerel 2 times/week). The FA composition of milk (% of total FA) was determined by direct transesterification and analyzed by GC-FID, blinded group. Nutritional surveys were analyzed by Bilnut software. FA concentrations at day 30 were compared between groups by linear regression, with a test interaction between M and C. Result: 80 mothers of term infants were included: Age 31.5±4.2, 66.1±9.8 kg (mean±SD). ALA was higher in MC (2.2%) C (1.3%) and M (1.1%) groups (p<0.003) vs. group O (0.8%). There was a tendency for the DHA to be higher in the MC group (0.54%) vs. O group (0.39%) (p=0.11). The ratio LA/ALA was the lowest=5.5 (p<0.001) in the group MC and bonded to an ALA rate to 2.1%. ARA is the highest in group C (0.37% vs. 0.33% MC, M and O=0.32, 0.34%; p=0.02). The dietary survey showed a slightly high fat diet compared to RDA. Conclusion: We recommend for lactating women, a balanced varied diet consisting of 170 g mackerel two times/week or equivalent, which covers the needs for DHA and ARA. Margarine consumption omega 3 and rapeseed oil improves the ratio LA/ALA (5.5) the most favorable ratio to increase the synthesis of DHA from ALA
