When we look at the brain, we now know that 60% of the brain is made from and runs on fats and oils. We also know now that 50% of these fats and oils is one single fatty acid DHA (docosahexaenoic acid). (Schmidt, M et al 97). So the most important and prevalent nutrient that the brain requires to grow properly and to function properly is DHA, which is found in abundance in Cod Liver Oil.
Then, when we look at how the brain grows and develops, we see that most of the brains growth, the actual size, is completed by seven years of age. At birth, the brain’s weight is 70% of an adult, a further 15% of brain growth occurs during infancy, and remaining brain growth takes place in the early school years. (J.Pediatrics March 2005)
Understanding when and how the brain grows leads us to understanding how essential and important the right fats, oils, and especially DHA are, in infancy and childhood to support this growth.
This is why we see studies like this one, from J.Pediatrics, Jan, 2003 that showed that when mothers supplemented their diet with Omega 3 DHA, during pregnancy and also while nursing their baby, that it actually increased the child’s IQ, by the age of four. It’s incredible what one nutrient can do.
