wiseslawa,
Ne bih mogla da se slozim sa vama po pitanju konstantnosti kvaliteta majcinog mleka.
U poslednjih nekoliko godina je objavljeno vise voma znacajnih studija koje pokazuju upravo suprotno. Posebno po pitanju zavisnosti koncentracije polinezasicenih masnih kiselina (omega-3, omega-6 i njihovog medjusobnog odnosa) u majcinom mleku i kvaliteta ishrane same majke. Danas kada znamo koliko su masne kiseline vazne u ishrani odojceta i male dece (posebno dokozaheksaeonska - DHA i arahidonska - AA), narocito za razvoj nervnog sistema i imunog sistema, ovakve informacije ne bi trebalo da se zanemaruju.

American Journal of Clinical Nutrition, Vol. 85, No. 6, 1457-1464, June 2007
http://www.ajcn.org/cgi/reprint/85/6/1457Both DHA and AA have been found in all breast milks examined to date via appropriate methods. Short-term diets clearly influences the LCPUFA content of breast milk, and there is evidence that habitual intake has an influence as well (4-6). In small studies, fish-eating populations have higher breast-milk DHA concentrations than do populations that do not consume marine foods (7,8), and there is evidence that poorly nourished mothers conserve PUFAs and LCPUFAs in their breast milk at the expense of saturates (9). Breast-milk FA concentrations, therefore, vary with the lifestyle of the population of lactating mothers under study; thus, FA concentrations vary by region.
Concentrations of DHA and AA in breast milk depend on the amount of these preformed FAs in the mother's diet and their biosynthesis from precursors. Milk DHA content appears to be closely linked to maternal dietary DHA intake, with dose-dependent linear increases in breast-milk concentrations of this nutrient with increased maternal intake (109). In our study, the 5 locales with the greatest breast-milk DHA concentration are Canadian Arctic, Japan, Dominican Republic, Philippines, and Congo (1.4–0.6%); all but Congo are coastal or island populations that have a high marine food intake. In contrast, the lowest breast-milk DHA values are for Pakistan, rural South Africa, Canada, the Netherlands, and France (0.06–0.14%). These populations are either inland or are developed countries, both of which are usually associated with low marine food consumption. Thus, the extreme values are consistent with studies suggesting that marine food–consuming populations have greater breast-milk DHA concentrations (7,8).
Jos vise ima dokaza da majke koje konzumiraju hranu u kojoj ima previse trans-masnoca (kakva je tipicna, svakodnevna ishrana vecine ljudi u razvijenom svetu) te iste trans masnoce prenose i bebi koju doje. Valjda nam je svima jasno kako trans-masnoce uticu na opste zdravlje.
