Many doctors recommend pregnant women take relatively large amounts of animal fats, which are an excellent source of cholesterol is necessary for normal development of the nervous system.
Recent research conducted on animals suggest another possible advantage of such a diet - it turns out that included, inter alia, in meat and eggs choline directly affects the activity of important genes in the fetus. Our study in mice indicates that the pregnant mother's diet, especially choline contained in it, can control "switches" controlling fetal brain development, says Dr. Steven Zeisel, a worker the University of North Carolina and senior author of the study. For the purposes of the study team dr. Zeisel have kept the two groups of pregnant mice. Animals in one group fed an additional dose of choline (1.1 mg / g body weight), while in the other used a simple. At a time in which the developing offspring in the hippocampus was created (one of the memory centers of the brain), fetuses removed, and isolated from their precursors of nerve cells were transferred to culture in vitro. In cells derived from offspring of mothers receiving an additional dose of choline found an accumulation of changes in histon - proteins function like their spool around which wraps a fragment of the DNA strands. These proteins protect in this way formed the "ball" of genetic material and restrict its activity. Choline-dependent changes were observed especially in related segments of DNA containing genes for G9a and Calb1, a protein important for the development and maturation of nerve cells. This means that an additional dose of choline in a direct way to affect the activity of genes and can thus accelerate the development of hippocampus. Ladies expecting a baby can also accelerate the development of his brain and by products. An excellent source of choline is in fact as well as any variety of nuts.
