I could go on and on about essential fatty acids (EFAs). They are important. They are found in breast milk. Only recently are they being put in formula and only in the more expensive lipil formula. They are similar to the cod liver oil that our parents may have given us. There are plant sources of EFAs (i.e. flax) and animal sources (i.e. fish). Animal sources appear to be better absorbed and more effective than plant sources. There is a good and well thought out article on EFA's that can be found at PWS Playroom.

These unsaturated fatty acids are easily used by your body to form the brain and the lipid layer around cells. Saturated fats (like butter) compete with unsaturated fats. There is some talk that ingestion of EFAs contributes to brain formation and intelligence. Have you heard about breast fed babies being smarter? If it is true, it is likely due to EFAs. Have you heard of fish being brain food? If this is true it is likely due to EFA's.

Check out the cherab organization website. There is a lot of anecdotal evidence about fatty acids and language development. I found this story persuasive.

Finally, there is the role of these EFA's in metabolism. I haven't seen much discussion about this. I would welcome anyone's opinion as this is a stretch for me. But, there are a group of receptors called PPAR. They bind fatty acids and they are involved in numerous diseases including diabetes. Saturated fatty acids appear to bind them and initiate an inflammatory response that can have many bad downstream effects, such as heart disease. Unsaturated fatty acids compete for these receptors and have an anti-inflammatory effect. I am mulling this over...
