Our brains are mostly fats. Most of the fat in the brain is in the form of long chain fatty acids.
These long chain fatty acids are in breast milk as well as more expensive bay formula in the form of DHA and AA.
Long chain fatty acids are synthesized in the body from short chain fatty acids in our foods. Oils, nuts, meats, and dairy are the primary source of the various fatty acids in our diet. Our body can synthesize these long chain fatty acids which are the building blocks of the brain. The process is similar to making a long railroad train by connecting the individual boxcars with links.
So what do trans fats do? They BLOCK the enzyme the body uses to make these links. I mean if God were to make a specific compound to block this long chain fatty acid making process it would be trans fats. Trans fats are so similar to the real thing that they totally confuse the process.
Fetal Cord blood measurement of fatty acid composition at birth have shown an inverse relation between trans fat levels and DHA levels in the blood. Please read this study-- http://www.ajcn.org/cgi/content/abstract/74/3/364
Also a study published in Nature compared cognitive function in infants breast fed. vs formula with LCFA vs formula without LCFA added. Cognitive function was clearly lowest in the third group.
Visual development issues are important too as the retina is struturally neural tissue.
Uauy, R., D. R. Hoffman, et al. (2003). "Term infant studies of DHA and ARA supplementation on neurodevelopment: results of randomized controlled trials." J Pediatr 143(4 Suppl): S17-25.
Healthy term infants who are not breast-fed may need long-chain polyunsaturated fatty acids (LCPUFA) in their feeding, based on the changes in plasma and tissue fatty composition. However, consistent functional effects across different studies conducted over the past two decades has been more difficult to document. The interpretation of these data has scientific and public interest with the introduction of LCPUFA supplemented formula. There are 14 controlled trials in term infants that have included formula feeding with or without LCPUFA and functional assessment of visual and other measures of neural development; in addition, 7 have evaluated specific measures related to cognitive development. We chose to examine the effect of DHA dose provided daily on the development of visual acuity to explain the differences in visual acuity responses across randomized studies. A "meta-regression" was performed with the use of a DHA effective dose as the independent variable and visual acuity at 4 months as the dependent variable. Since the two main dietary determinants of DHA status are the LNA provided and the preformed DHA consumed, we defined DHA equivalent dose across studies by assuming a 1%, 5%, and 10% conversion of LNA to DHA. Results indicate a strong and significant effect of DHA equivalent dose on magnitude of the visual acuity response at all conversions tested; greatest significance was found when using a 10% bioequivalency (r(2)=0.68, and P=.001). We conclude that there is a significant relation between the total DHA equivalents provided and effectiveness as defined by visual acuity measurements at 4 months of age.
SO MOMS--NO FAST FOOD AND FRANCHISE FOOD IN PREGNANCY AND LACTATION FOR THE MOM. WATCH THE LABELS FOR HYDROGENATED OILS. EAT SIMPLY.
More later. Have a smart baby!
