Dear Colleagues: There is an excellent article on the ins and outs of adding various unsaturated fatty acids to artificial infant formulas in the September 1996 issue of AAP News,page 22. It strongly supports the issue that breast milks' unique fatty acid composition is terribly sophisticated and we don't yet understand this field well enough to just dump some new fatty acids in formulas and presume they are safe for the bottle-fed infant. It does a great job of illustrating the point that just adding exogenous DHA or Aracidonic acid to formulas may be more harmful than helpful and that a great deal more research is needed before these substances should be added to formulas. Its good reading. Tom Hale, Ph.D.
