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 (http://www.pwsplayroom.com/efa.htm ).
